A
Troubleshooting Appendix

This appendix describes different ways of troubleshooting problems that may occur when you are using change management applications.

You may decide to contact an Oracle Worldwide Customer Support representative regarding a problem with the change management applications. If so, you may be asked to use one of the approaches described in this appendix to obtain information that will help the representative determine the source of the problem.

Using Environment Variables When Running Change Manager from the Command Line

You can set environment variables in the MS-DOS or UNIX command line before you run the Change Manager application from the command line. The following environment variables may provide information that is useful for troubleshooting and debugging change management application problems:

Enabling Tracing and Debugging for Change Management Applications

You can turn on tracing and debugging facilities for the change management applications to help troubleshoot problems.

You can enter different properties in the ClientConfig.properties file in the ORACLE_HOME/sysman/config directory for Oracle Enterprise Manager to obtain more tracing and debugging information about change management applications. Table A-1 displays the properties and a description of each property.

By default, the trace files for change management applications are written to the ORACLE_HOME/sysman/log directory for Oracle Enterprise Manager.


Note:

The OCM_TRACE.ENABLED property in the ClientConfig.properties file must be set to true for the other properties whose names begin with OCM_TRACE in the ClientConfig.properties file to be meaningful. 


Table A-1 Using ClientConfig.properties to Enable Tracing and Debugging  
Property and Settings  Description 

OCM_TRACE.ENABLED={true|false} 

If true, enables output of informational and problem trace messages. 

OCM_TRACE_FILE.ENABLED={true|false} 

If true, enables output of trace information to a file. The setting of the OCM_TRACE_VERSIONING.ENABLED property determines the name of the trace file. 

OCM_TRACE_VERSIONING.ENABLED={true|false} 

The OCM_TRACE_FILE.ENABLED property must be true for the OCM_TRACE_VERSIONING.ENABLED property to be meaningful.

If the OCM_TRACE_VERSIONING.ENABLED property is true, a new version of the trace file is created for each run of the application. The file has a name in the format Oracle Change Manager_nnnnnn.log, where nnnnnn represents a series of numbers.

If a change management application is running in more than one session on your machine, examine the timestamp of each trace file to determine the trace file that is associated with each session. The trace file with the earliest timestamp is the trace file for the session that started first, and so on.

If the OCM_TRACE_VERSIONING.ENABLED property is false or not used, the trace file has the name Oracle Change Manager.log, and the file is overwritten for each run of the application. 

OCM_TRACE_DEBUG.ENABLED={true|false} 

If the OCM_TRACE_DEBUG.ENABLED property is true, general debugging information (such as property values) is output to the trace file while Change Manager runs. 

OCM_TRACE_DEBUG_VERBOSE.ENABLED={true|false} 

If the OCM_TRACE_DEBUG_VERBOSE.ENABLED property is true, more detailed debugging information, including class names and line numbers, is output to the trace file while Change Manager runs. 

VDB_DEBUG={true|false} 

If the VDB_DEBUG property is true, database calls are output to the trace file.

This property is not specific to change management applications. It can be used with other Oracle Enterprise Manager applications.

Use this property in the ClientConfig.properties file to capture database calls in the trace file when you are running Change Manager standalone.

Use this property in the omsconfig.properties file in the $ORACLE_HOME/sysman/config directory to capture database calls in the trace file when you are running Change Manager connected to an Oracle Management Server.

Use this property in both the ClientConfig.properties file and the omsconfig.properties file if you want to capture database calls in the trace file regardless of how you are running Change Manager. 

VDB_VERBOSE_DEBUG={true|false} 

If the VDB_VERBOSE_DEBUG property is true, more detailed information about database calls, including SQL statement issued and return values, is output to the trace file.

This property is not specific to change management applications. It can be used with other Oracle Enterprise Manager applications.

Use this property in the ClientConfig.properties file to capture database calls in the trace file when you are running Change Manager standalone.

Use this property in the omsconfig.properties file in the $ORACLE_HOME/sysman/config directory to capture database calls in the trace file when you are running Change Manager connected to an Oracle Management Server.

Use this property in both the ClientConfig.properties file and the omsconfig.properties file if you want to capture database calls in the trace file regardless of how you are running Change Manager.
