Console

This chapter introduces the Oracle Enterprise Manager Console and provides an overview of its components. The following topics are discussed in this chapter.

Enterprise Manager Console

The Console is the primary interface used for all Oracle Enterprise Manager operations. It provides menus, toolbars, and the framework to access Oracle tools and utilities in addition to those available through other vendors. The graphical configuration of the Console and the tools available are determined by the optional products installed and user preferences. See Figure 1-1, "Console Window" for an illustration of a Console screen.

Components

The Console uses a master/detail configuration to provide an integrated, consistent, and efficient way of managing your enterprise environment. When an object in the Navigator (master) is selected, the appropriate interface is displayed on the right-hand side of the Console (the detail pane). Information displayed on the right-hand side of the Console can be a multi-column list, property sheet, or overview page.

Navigator

The Navigator displays a hierarchical list of all the targets in a network, providing a direct view of targets such as databases, groups, listeners, and nodes, plus the objects that they contain. The Navigator shows all the network targets with their relationships to other objects. Objects within the Navigator can be managed via context-sensitive menus. For example, you can also perform many administration tasks from the Navigator, such as creating, editing, or dropping tablespaces. See Chapter 3, "Navigator" for information.

Detail Pane

The Detail pane displays information or functionality relevant to whatever object is selected in the Navigator. Some elements that can be displayed are multi-column lists summarizing attributes or contents of an object, property sheets providing object information and any functionality relating to the object, or comprehensive overview pages with links to related Quick Tours or functional overviews.

Console Menus

The Console menu bar provides access to the following menus:

Figure 1-2 Console Main Menu

Text description of menu.gif follows.

Text description of the illustration menu.gif

The File, Object, Tools, Configuration, and Help menus are described in this section.

When using the Console menus, note the following:

Context-Sensitive Menus

You can click the right mouse button on objects in the Navigator or some windows of the Console to display a context-sensitive. This menu usually contains a subset of the options that are available through a menu in the main menu bar, or functions that are specific to a selected object in the Navigator. For example, if you click the right mouse button on a group in the Navigator, a menu appears with the menu options from the Object menu. Dialogs and property sheets displaying objects in general use the context-sensitive menus for most, if not all operations that can be performed on an individual object.

File Menu

The File menu items allow you to exit the system.

Object Menu

The Object menu provides object-specific functionality for an object selected in the Console Navigator. Though menu options change depending on the object, five base menu options always appear.

Create

Displays the Create Object dialog allowing you to create Navigator objects such as jobs, events, database objects, and report definitions.

Create like

Displays the object's Create/Edit property sheet allowing you to create a new object based on the original object's parameter settings.

View/Edit Details

Displays the object's Edit property sheet allowing you to modify the selected object's parameters.

Delete

Deletes the selected object from the Navigator.

View Published Reports

Displays the Enterprise Manager reporting home page.

Configuration Menu

The Configuration menu provides options to set up administrator and system configurations.

Preferences...

Displays the Edit Administrator Preferences property sheet, which allows the current administrator to change preferences, including access levels and login credentials. See "Changing Administrator Preferences" for more information.

Add Services to tnsnames.ora

Updates the local network configuration file (tnsnames.ora) with discovered services information.

Font Settings

Changes the font settings for the Console as well as any applications launched from the Console.

Font settings in pop-up menus will not change even if you have specified to change the font settings.

Report Data Purge Options

Displays the Report Data Purge Options dialog. This dialog allows you to set the purge policy for the report data log. The report data log contains information that is collected over time and used in service level reports and enterprise reports. The report data log is stored in one or more tables within the Enterprise Manager repository. All event occurrences and service level response time tasks are logged to the report data log.

SQL Logging

Allows you to log SQL in a permanent log file. SQL Logging allows you to specify the SQL logging file information and options. When you are connected to the Management Server, you can query the log (View SQL Log).

View SQL Log

Available only when you are connected to a Management Server, this menu item displays the SQL Log Viewer, which allows you to view and purge contents of the log.

Configure Paging/Email

Allows you to set up enhanced notification (paging/email) systems for administrators. This menu option is only available to super administrators.

Manage Administrators

Displays the Administrator Manager Accounts property sheet for adding, modifying, and removing administrators. This option is only available to Super Administrators. See "Managing Enterprise Manager Administrators" for more information.

Grant Access to Targets

Displays the Access to Targets dialog, which allows super administrators to customize Navigator views for all regular administrators. See "Granting Access to Targets" for more information.

Set Paging/Email Blackout

Displays the Paging/Email Blackout dialog. Paging/Email Blackout allows an administrator with super administrator privileges to suspend paging and email notifications for specified targets and/or services that have been previously discovered in the Navigator. See "Paging/Email Blackout" for more information.

View Reporting Website Configuration

Displays the current Reporting webserver configuration. An error message is displayed if no webserver has been configured.

Define Management Regions

Displays the Management Regions property sheet. The Management Regions feature allows super administrators to partition the targets of a particular repository and assign them to a subset of the available Management Servers.

Tools Menu

The Tools menu allows you to execute database applications and other utilities that have been installed on your system. The menu options in the Tools menu depend on your installed Oracle Enterprise Manager configuration. The standard complement of options includes:

Other optional applications may also be available from this menu.

Help Menu

From the Help menu, you can access the Enterprise Manager online help system. You can also access Enterprise Manager's Quick Tours. Enterprise Manager comes with a variety of Quick Tours, each providing a comprehensive overview for Enterprise Manager and specific integrated applications. Enterprise Manager version information is also available.

Toolbars/Tool Drawers

The Console toolbar, located along the upper-left side of the Console, allows you to access basic manipulation functions for objects in the Navigator and the Console in general. Some functions of the toolbar will be unavailable depending on the object selected in the Navigator. Object functionality are (top to bottom):

Figure 1-3 Console Toolbar and Tool Drawers

Text description of ch_cons3.gif follows

Text description of the illustration ch_cons3.gif



The Console tool drawers, located below the toolbar, provides quick and easy access to a wide variety of integrated applications. Placing the cursor over any drawer, or content of that drawer displays the application name.

Managing Enterprise Manager Administrators

Enterprise Manager is a multi-administrator system: every person who is administering systems using Enterprise Manager has their own administrator account which they use to log into the Console.

Types of Enterprise Manager Administrators

The installation of Enterprise Manager creates two super administrator: reports_user and sysman. The reports_user super administrator owns all predefined reports of the reporting system. See "Enterprise Manager Reporting"for more information. The super administrator sysman creates administrators using the Manage Administrators option in the Console Configuration menu. In addition to an administrator name and password, each account can be tagged as a "Super Administrator" account or an account to which the administrator has access to only jobs and/or events. Differences between the two types of accounts are as follows:

Typically, all administrators share a single Enterprise Manager repository, which allows administrators to share information. Although you can set up multiple repositories, administrators using different repositories will not have access to each other's information; there is no sharing of data between repositories. Administrative data stored in the repository is filtered based on administrator permissions.

Preferred Credentials must be set up for each administrator account. When an administrator connects through the Navigator, the preferred credentials used are those defined explicitly for that administrator.

Managing Administrator Accounts

Enterprise Manager administrators are created, edited, and deleted with the Manage Administrators option of the Console Configuration menu. The Manage Administrators option displays the Manage Administrator Accounts dialog (Figure 1-4, "Manage Administrator Accounts"). The Manage Administrators option is only available to Super Administrators. Super Administrators have full privileges for all objects and can create, edit, and delete other administrators. The Super Administrator sets up the administrator name and initial password and determines whether an administrator is a Super Administrator or regular administrator. The Super Administrator also determines whether the administrator has access to the job and event systems.

In this dialog, you can:

Figure 1-4 Manage Administrator Accounts

Text description of addadmin.gif follows.

Text description of the illustration addadmin.gif

Creating or Editing an Administrator Account

To add a new administrator, click Add in the Manage Administrator Accounts dialog to display the Create Administrators dialog.

In the Create Administrators dialog, enter a unique administrator name and password for the Enterprise Manager administrator. Note that the administrator name (account login used by Enterprise Manager) is not the same as a database username (account login used by the database).

Figure 1-5 Create Administrator Account

Text description of ctreadmn.gif follows.

Text description of the illustration ctreadmn.gif

Check the access available to the administrator:

Super Administrator

Allows the administrator to add other administrators, as well as access to all created objects, e.g., jobs, events, and groups.

Access to Job System

Allows the administrator access to the Job system, but does not automatically give access privileges for specific jobs.

Access to Event System

Allows the administrator access to the Event system.

After an administrator has been created, the administrator can log in to the Enterprise Manager Console and set up administrator preferences.

If you click the Edit button, the Edit Administrator Preferences window displays. You can then edit the preferences for the selected administrator.

Granting Access to Targets

Enterprise Manager Super Administrators can control what regular administrators see in the Console Navigator through the Access to Targets dialog. This dialog can be displayed by either choosing Grant Access to Targets from the Console's Configuration menu, or clicking Grant Access to Targets from the Manage Administrator Accounts dialog. See "Managing Administrator Accounts".

Figure 1-6 Access to Targets Dialog

Text description of accessta.gif follows.

Text description of the illustration accessta.gif

The ability to control what targets and services appear to different users helps simplify maintaining your enterprise. For example, if you are managing 100 targets in your enterprise, and Administrator A's responsibilities require that he manage a only 10 targets, the Super Administrator can specify that only the 10 managed targets appear in the Navigator when Administrator A logs into the Enterprise Manager Console. Again, only Super Administrators can customize Navigator views.

To customize the Navigator for regular administrators:

  1. From the Console's Configuration menu, choose Manage Administrators. The Manage Administrators Accounts dialog appears.
  2. Click Grant Access to Targets. The Access to Targets dialog appears. The Targets column can be expanded to display lower level objects in the Navigator.
  3. Under each administrator, click all checkboxes that correspond to the objects you want to appear in the Console Navigator when that user logs in.
  4. Click OK when finished to close the dialog.
  5. Click Close to close the Manage Administrator Accounts dialog.

Reassigning Object Ownership

If you attempt to delete an administrator who owns any object, the Object Ownership Management dialog appears. See Figure 1-7, "Object Ownership Management". The dialog allows you to reassign the objects to another Enterprise Manager administrator. If you do not reassign the objects, the objects are deleted along with the administrator.

Figure 1-7 Object Ownership Management

Text description of objowner.gif follows.

Text description of the illustration objowner.gif

Changing Administrator Preferences

The Edit Administrator Preferences property sheet is displayed with the Preferences option of the Configuration menu and allows you to modify the administrator preferences of the user who is currently logged into the Console. The pages in the property sheet are:

General

The General Preferences page allows a Super Administrator to change an administrator's password and access privileges.

Figure 1-8 Administrator General Preferences

Text description of genprefs.gif follows.

Text description of the illustration genprefs.gif

Notification

The Notification page allows you to set up paging and email notification methods for the administrator. This page consists of a hierarchical tree list and a right-side modal area that changes according to the object selected in the navigator. The tree list consists of three top-level objects:

Figure 1-9 Administrator Notification Preferences

Text description of notipref.gif follows.

Text description of the illustration notipref.gif

Filters

Notification filters allow each administrator to specify when to send an email notification as opposed to a page notification as a result of a job or event status change.

Job Notification Filter

The Job Notification Filter allows you to filter email/pages sent to an administrator according to job status. As with the Event Notification Filter, filtering is set at the user level by checking or unchecking the desired option. Selecting all job statuses provides no filtering.

Email

This page allows you to specify notification parameters for email.

Figure 1-10 Administrator Notification Preferences: Email

Text description of notemail.gif follows.

Text description of the illustration notemail.gif

Email Subject

This page allows you to select the content and format of the email subject line. By default, Type, Name, and Status are selected. You use the left/right arrows to move items back and forth between the Available and Selected lists.

Once an item has been selected, you can control the order in which the item appears by selecting it in the list and using the up/down arrows (located to the immediate right of the Selected list) to reposition the item within the list.


Note:

The following information also applies to inserting content into the Email/Paging message body.

Text description of notpage.gif follows.

Text description of the illustration notpage.gif

Paging Status Codes for Numeric Pages

Numeric pages need to be interpreted as follows:

For job notifications, you will receive a 3 digit number which indicates the job status.

For event notifications you will receive the a 3 or 4 digit number indicating the event status.

The event status and job status codes are listed as follows:

100 = Job Started

200 = Job Completed

300 = Job Failed

400 = Job Deleted

500 = Event Cleared

600 = Event Warning

700 = Event Critical

800 = Event Node Down

900 = Event Unknown

1000 = Event Assignee Changed

Email/Paging Message Body Definition

This page allows you to select the content and format for the body of the email or page message. By default, Name, and Status are selected. You use the left/right arrows to move items back and forth between the Available and Selected lists.

Figure 1-12 Administrator Notification Preferences: Email/Paging Body

Text description of empgbody.gif follows.

Text description of the illustration empgbody.gif

Expanding the Message Body object in the navigator and selecting per Test allows you to use a subset of the following option settings on a per test basis. See "Email Subject" for more information on manipulating message content.

Timestamp Format

This option is available if Timestamp is chosen from the Selected list. You use the pull-down menu to select one of the pre-defined formats.

Do not include titles

When selected, classification titles such as Status, Service Name, and Timestamp are omitted from the message.

Append job output

When selected, job output is appended to the end of the notification. For instances where job output is large, you may want to specify a limit to the message length. If the job output pushes the notification length past the specified limit, then the job output will be truncated, not the message itself.

Schedule

Use this property sheet page to indicate when you want to be paged and/or e-mailed. Determine the day, hour, and the method of notification. You will receive notifications only on the objects you have permission to access.

Figure 1-13 Administrator Notification Schedule

Text description of schdpref.gif follows.

Text description of the illustration schdpref.gif

An administrator can be notified by email, paging, or both email and paging. Paging is recommended for urgent jobs, events, or critical systems.

To determine notifications:

  1. Select in the appropriate day/hour to set the notification method for that time period.
  2. Click No Notification, Pager, Email, or Pager and Email at the bottom of the dialog to set the notification type for
  3. Repeat steps 1 and 2 for each notification method.

If you want to set the same notification an entire day or an hour of the day, click on the heading for that row or column. For example, if you want to set up paging notification for Saturday, click on the Sat heading after you have selected Pager at the bottom of the screen. You can also drag the cursor to "paint" across multiple cells.

Access

Use this property sheet page to determine the default permissions you want to assign to other administrators for the objects you create. This allows other Enterprise Manager administrators to share objects, such as events and jobs, that you have created. If you work on a team, this page lets you assign access privileges to all the members of the team at one time. When an object is created by an administrator, that administrator is the owner and automatically has full permissions. The owner's permissions cannot be modified.

Figure 1-14 Administrator Default Permissions

Text description of defperms.gif follows.

Text description of the illustration defperms.gif

Access-control permissions apply to event, group, and job objects. When these objects are created, the default permissions are assigned to other Enterprise Manager administrators according to the selections in this page. These initial permissions can be overridden with the Permissions page of the object's property sheet.

For more information, see the following sections:


Note:

Changing your default access level does not retroactively change access levels on existing objects.




The levels of access that you can assign to an Enterprise Manager administrator are shown in Table 1-3, "Administrator Access Levels".

Table 1-3 Administrator Access Levels
Permission Level Description

None

This access does not allow the administrator to view this object anywhere.

View

This access allows the administrator to view the object, inspect object properties, view job/event status and outputs, and receive notifications if the object is an event.

Modify

This access allows the administrator to edit the object's properties except those reserved for Full permission.

Full

This access allows the administrator to delete the object, modify permissions for other administrators, and change the ownership of the object.

Notify

This access allows the administrator to receive event notifications on the objects. Notify permission cannot be assigned if the administrator's permission level is set to None.



Preferred Credentials

The Administrator Preferred Credentials property sheet page displays a list of targets in the network, along with the target type and the administrator name for accessing the target. The property sheet page is accessed with the Administrator Preferences option of the Configuration menu. Each row in the list of the property sheet includes:

You can click on a column heading to sort on that column. See Figure 1-15, "Administrator Preferred Credentials"for an illustration of the property sheet.


Note:

Individual instances of an Oracle 9i Real Application Cluster are listed. Oracle recommends that all instances of a Oracle 9i Real Application Cluster use the same preferred credentials as the Oracle 9i Real Application Cluster.




Also, the Intelligent Agent authenticates the user name and password for all jobs and many events that it runs. These credentials are used when you access a network service in the Navigator or Group, and when running jobs and registering events. If you do not set the preferred credentials correctly, jobs and events may fail. See "Job Credentials" and "Registering Events" for more information.


Important:

Changes to the Preferred Credentials will not be automatically propagated to previously registered jobs and events. In order to update these jobs and events with the new preferred credentials, you must de-register and subsequently re-register the jobs and events.




Oracle recommends that if some services of a particular type require the same credentials, use the <DEFAULT> credentials selection for that service type to have those credentials used by all services of that type.

For example, if Administrator_1 has a username and password of foo/bar on all the databases that he manages, the administrator needs to enter foo/bar as his credentials in the <DEFAULT> database entry. All database administration tasks will use these <DEFAULT> credentials.

Furthermore, if the administrator has just one database which requires different credentials from foo/bar, he can enter different credentials for that database by selecting that specific database.

For NT users, you must set the preferred credentials for the node (where the NT Intelligent Agent resides) to be the same as the user that is set up to "Logon as a batch job."

Figure 1-15 Administrator Preferred Credentials

Text description of prefcred.gif follows.

Text description of the illustration prefcred.gif

Setting Administrator Credentials

Select any row to update the credential fields for the object identified in the row.

Username

Enter the username. This field is required if a password needs to be entered.

Password

Enter the password associated with the username.

Confirm Password

Confirm the password.

Role (Database only)

Select the role from the pull-down list. You need to login with the SYSDBA or SYSOPER role to start up or shut down a database.

Changes to the credentials are recorded when you move to another line. When you are finished, save all your updates by clicking the OK button at the bottom of the property sheet.

Saving Logon Information as a Preferred Credential

Another convenient way to specify Preferred Credentials for discovered services is to select the Save as Preferred Credential option when manually connecting to a service from the Console or integrated application. For example, you attempt to access a newly discovered database from the Console Navigator. Enterprise Manager displays the Connect Information dialog so that you can log in to the database. You type in the requisite information and check the Save as Preferred Credential option. Click OK to log on to the database and save the logon information as a Preferred Credential for this service.

Saving the Contents of a List

Save list allows you to extract information from a multi-column list (such as the Job or Event History panes) and save it in a variety of formats (text, HTML, or Comma-Separated-Values). For example, you can select one or more entries in the Event History pane. By selecting the Save List from the Object menu, you can save the list information (Event, Target, Target Type, Severity, Date/Time, Assigned To, Owner) to an HTML file. The dialog consists of the following elements:

File Name

The name and directory to which you want to save the file information.

Browse

Displays the File Save to dialog. Choose the desire location and file name.

Format

Select HTML (table), Text row, or comma-separated-values (used by spreadsheets or other applications).

View

Active only when HTML is selected as the file format, allows you to view the generated HTML table through the default browser for your system.

Rows

Configuring Enhanced Notifications (Paging/Email)

Enhanced notifications allows Enterprise Manager administrators to be notified either via email or pager. Email configuration allows you to specify the mail service information for your system. Paging configuration allows you to define paging servers, specify pager numbers, and specific paging parameters. For explicit infomation on setup and configuration, see the Oracle Enterprise Manager Configuration Guide.

Management Regions

A management region is a subset of the managed nodes and a subset of management servers. The same Enterprise Manager repository can contain multiple management regions, but a particular node is a member of one and only one management region. You can only assign the Management Server to be in one and only one management region.

The management regions feature allows you to partition the nodes of a particular repository and assign them to a subset of the available Management Servers.

Once this partitioning is performed, the failover and load-balancing operations guarantee that cross-regional traffic is eliminated. The Management Servers that belong in the same partition distribute the management load amongst themselves.

For example, if you have a large, global deployment of Enterprise Manager, or have Enterprise Manager deployed across a mixture of LANs and WANs, using management regions can greatly improve performance over slow networks by allowing you to assign a subset of Management Servers and a subset of discovered nodes to a management region, thus eliminating cross-regional/cross-network communication. Additionally, the ability to segregate a large network makes the use of management regions ideal for mapping firewall boundaries.

If no Management Server is available to service a particular management region, even though Management Servers exist and are serving other regions, you can log on using a Management Server from a different region. The Oracle Enterprise Manager Console will not experience any disruption from an unmonitored management region. You can connect to a Management Server in any Management Region and you will be able to see all nodes in all Management Regions.

Defining a New Management Region

There are two ways to define a Management Region:

By default, Enterprise Manager Configuration Assistant creates the initial "default" Management Region. Under this configuration, all Management Servers that use the existing Repository, as well as all discovered nodes within the Repository, are placed within this DEFAULT Management Region. This single, default management region is sufficient for most situations. However, in order to take advantage of the management region functionality, you must create additional management regions and specify a subset of discovered nodes with a subset of Management Servers within each management region.

To create a new Management Region using the Enterprise Manager Console:

  1. Logon as a super administrator to any of the Management Servers working in DEFAULT region.
  2. Select Define Management Regions from the Console Configuration menu to access the Management Regions property sheet.
  3. Select the Regions tab from the Management Regions property sheet. The Regions page appears.
  4. Click the Add Regions button on the Regions page. The Add Management Regions dialog appears.
  5. Create a new region by typing the its name into the Management Region Name field and clicking the OK button.

Alternatively, you can use Enterprise Manager Configuration Assistant to create new Management Regions by editing an Oracle Management Server configuration and pointing it to a new repository.

Adding a Management Server to a Region

In this example, we are assuming that there are two already existing Management Servers (OMS1 and OMS2) using the same Repository. In this example, both OMS1 and OMS2 are running.

  1. Logon as a super administrator to any of the Management Servers working in DEFAULT region.
  2. Select Configure Management Regions from the Console Configuration menu to access the Management Regions property sheet.
  3. Select the Regions tab from the Management Regions property sheet. The Regions page appears.
  4. Click the Add Regions button on the Regions page. The Add Management Regions dialog appears.
  5. Create a new region by typing its name (R1 for this example) into the Management Region Name field and clicking the OK button.
  6. Select the Assign Management Servers tab on the Management Regions property sheet. The Assign Management Servers page appears. Assign OMS1 to R1.
  7. Select the Assign Nodes tab from the Management Regions property sheet. The Assign Nodes page appears. Assign the required nodes to R1. Important: To assign nodes to R1, the Management Server for R1 must be running. Click OK.

Adding Discovered Nodes to a Management Region

  1. Logon as a super administrator.
  2. Select Define Management Regions from the Console Configuration menu to access the Management Regions property sheet.
  3. Select the Regions tab from the Management Regions property sheet. The Regions page appears.
  4. Click the Add Region button on the Regions page. The Add Management Regions dialog appears.
  5. Create a new region. For example, R3, by typing the name into the Management Region Name field and clicking the OK button.
  6. Install Management Server or Management Servers.

    Install the Management Server in a new ORACLE_HOME.

    If you are installing from the database CD, choose the install type: Oracle9i Management and Integration>Oracle Management Server.

    If you are installing from the separately licensable packs CD, choose the install type: Oracle Enterprise Manager Packs and Management Infrastructure> Custom>Oracle Management Server.

    Refer to the installation guide provided with the database release or the installation guide provided with the separately licensable packs.

  7. Configure this Management Server (or Management Servers) to be in the new region, R3, using the Enterprise Management Configuration Assistant.
  8. Bring up this Management Server (or Management Servers). At this point there will be two regions available: DEFAULT and R3.
  9. Log on as a super administrator using one of the new Management Servers in R3.

Discover all the nodes you need to add. They will automatically be placed in the R3 region.

Removing a Management Region

A Management Region must be empty before attempting to remove it. First, ensure that there are no nodes in the region. Second, ensure there are no Management Servers in the region.

  1. Logon as a super administrator.
  2. Select Define Management Regions from the Console Configuration menu to access the Management Regions property sheet.
  3. Select the Regions tab from the Management Regions property sheet. The Regions page appears.
  4. Select the region you wish to remove.
  5. Click the Delete Region button. You are asked if you wish to continue.
  6. Click Yes.

Managing HTTP Servers

HTTP server management allows you to discover, start up, shut down, and monitor the server's operational status via the Event system. Additional functionality (extra job tasks and event tests) are available when the e-Business Management Tools (part of the Diagnostics Pack) are installed.

Discovering HTTP Servers

You discover a web server as you would any other managed target from the Enterprise Manager Console. See "Discovering Targets". The discovery process does not require the web server to be running. Once discovered, you set the server access authorization through the Enterprise Manager Preferred Credentials (Node). See "Preferred Credentials".


Important:

When running on UNIX, if the web server is listening on a port number less than 1024, the administrator must have root privileges in order to submit startup or shutdown jobs to the server.




Starting Up or Shutting Down a HTTP Server

Once an HTTP server appears as a managed object within the Console Navigator, you can select Startup from the context-sensitive menu. HTTP server management utilizes the Enterprise Manager Job system to perform the actual startup operation. For this reason, you can also start the HTTP server by selecting Create Job from the Console Job menu, selecting Web Server as the Target Type, and selecting the Startup job task. After the startup job task is submitted, a dialog displays indicating the task has been submitted to the Job system. Status messages pertaining to this task appear in the Console's Job Pane.

To stop an HTTP server, select the desired HTTP server from the Console Navigator and select Shutdown from the context-sensitive menu. As with web server startup, you can also shut down the server from the Edit Web Server General page, or use the Enterprise Manager Job system directly.

Alternatively, you can select Edit to display the Edit Web Server General Page. The current web server state is selected (Shut Down or Started). To start the web server, select Started and click OK.

Determining the Status of HTTP Servers

Select a discovered HTTP server from the Console Navigator. HTTP server status and configuration information displays in the detail view. Information displayed pertaining to the selected web server includes:

Paging/Email Blackout

Paging/Email Blackout allows an administrator with super administrator privileges to suspend paging and email notifications for specified targets and/or services that have been previously discovered in the Navigator. Paging/email blackouts deactivate enhanced notification (email/paging), thus preventing Enterprise Manager administrators from being flooded with emails and pages if a managed target/service is brought down. For example, if a target is brought down on a regular basis for scheduled maintenance, a super administrator can schedule a paging/email blackout for that target to prevent enhanced notification during the maintenance period.

In addition to paging/email blackouts, the Enterprise Manager administrative framework also allows you to specify target-level blackouts to suspend all management and data collection activity for specific targets in your enterprise. See "Target-level Blackouts".

Specifying Total Paging/Email Blackout

Total paging/email blackout specifies that a blackout be started immediately with an indefinite duration. The super administrator must manually turn off Total Paging/Email before any new blackout schedules can take effect or existing blackout schedules resume. To specify a total paging/email blackout:

  1. Choose Set Paging/Email Blackout from the Console's Configuration menu.
  2. Check Total Paging/Email Blackout
  3. Click OK.

Note:

You can also access Total Paging/Email Blackout menu item from a target's context-sensitive menu in the Enterprise Manager Navigator.




Defining a Paging/Email Blackout

To define a paging/email blackout for a specific node:

  1. Select a target from the Navigator and then choose Set Paging/Email Blackout from the Console's Configuration menu. Optionally, you can select an object in the Navigator and access Set Paging/Email Blackout through the context-sensitive menu.
  2. Click Create. The requisite naming and scheduling UI are displayed. Important: Be sure that Total Paging/Email Blackout is not checked for either the specific service or its parent target.
  3. Specify a Blackout Name. All Blackout names for this node/service must be unique. Note: the Target name reflects the node/service selected in the Navigator and is not editable from this dialog.
  4. Select an Occurrence

    Select the frequency that you want the paging/email blackout to occur. The choices are Once, On Interval, On Day(s) of Week, and On Date(s) of Month.

    • Once--schedules the blackout only one time beginning and ending on the dates and times you choose.

Select the value you want to change and click on the scroll buttons. You can also type in a new value. Select an Effective Period in which your blackout schedule will be valid.
    • On Day(s) of Week--allows you to schedule the blackout on one or multiple days (Sunday, Monday, etc.) of the week. Click on the days of the week to select the days you want the blackout period scheduled and set a start time or duration. Select an Effective Period in which your blackout schedule will be valid.
    • On Day(s) of Month--allows you to schedule the blackout on one or multiple days (1 - 31) of the month.

  5. Click OK.

Important:

When selecting On Day(s) of Month or On Day(s) of Week, be aware that each day terminates at 12:00 A.M. This is important when scheduling paging/email blackout periods that span the day change (12:00 A.M.).

For example, if you wish to schedule a blackout that begins on Tuesday at 10:00 P.M and lasts for six hours, you must define two blackout periods:

  • Tuesday from 10:00 P.M. to 11:59 P.M.
  • Wednesday from 12:00 A.M. to 4:00 A.M.



Making a Copy of an Existing Blackout Schedule

To schedule a paging/email blackout schedule for a node that is identical to that of another managed node:

  1. Choose Paging/Email Blackout from the Console's Configuration menu. Optionally, you can select an object in the Navigator and access Paging/Email Blackout through the context-sensitive menu.
  2. Select a Blackout Schedule entry from the Blackout Name list.
  3. Click Create Like. A new entry is created in the list prefixed by "Copy of."
  4. Modify the blackout period parameters (such as Blackout Name) as desired and click OK.

Turning Blackout Schedules On and Off

Once you have defined one or more paging/email blackout periods for a node/service, they persist in the Blackout Name list associated with the node/service until deleted. You can turn paging/email blackout on or off by checking the box located to the left of the individual blackout name. You can edit the Occurrence parameters to reflect the present date and time. Paging/email blackouts are set ON by default.

Deleting Paging/Email Blackout Periods

  1. Choose Paging/Email Blackout from the Console's Configuration menu. Optionally, you can select an object in the Navigator and access Paging/Email Blackout through the context-sensitive menu.
  2. Select the desired Blackout Name.
  3. Click Delete.

Viewing Blackout Periods

Once you have defined blackout periods on multiple nodes, you can view them by selecting the desired target in the Console Navigator and choosing Paging/Email Blackout from the Navigator menu. If you select a high-level folder from the Navigator, such as Databases, Groups, or Nodes, rather that an individual target, all blackout periods defined in the container type are displayed.

Target-level Blackouts

Target-level Blackouts allow Enterprise Manager users to suspend any or all management and/or data collection activity on one or more managed targets. This capability permits maintenance or emergency operations to be performed. Target-level Blackouts must be set on the target running a 9i version of the Intelligent Agent and cannot be set from the Console. See the Intelligent Agent User's Guide for more information.
