Chapter 2. LogsThis topic provides information about the OMEGAMON for Db2 PE logs.

The OMEGAMON for Db2 PE logs provide summarized information about various events duringOMEGAMON for Db2 PE execution. You can save some of this summarized information for use in laterprocessing. The following events are reported:

• Records in exception status• DB2 START/STOP TRACE commands• Reduction interval completion by report set• SAVE subcommand completion by report set• RESTORE subcommand completion by report set• Errors and messages• IFCID record distribution

How to generate logs or how to prevent log generation

The OMEGAMON for Db2 PE logs are generated automatically for each OMEGAMON for Db2 PE execution,provided there are valid DD statements in your JCL. To prevent generation of these logs, omit the ddnamefrom your JCL (the preferred method), or specify DUMMY in the definition.

Different log types

The following OMEGAMON for Db2 PE logs are available:

• The DPMLOG execution log provides a listing of messages issued during command stream validation andOMEGAMON for Db2 PE initialization. It also reports any errors during the execution of OMEGAMON forDb2 PE.

• The exception log provides a listing identifying accounting and statistics records with at least one fieldcontaining a value outside user-specified limits.

• The job summary log includes the following occurrences in OMEGAMON for Db2 PE processing:

– Detection of a DB2 START TRACE or DB2 STOP TRACE command– Reduction interval completion by report set– SAVE subcommand completion by report set– RESTORE subcommand completion by report set– Key error and w
