Ending performance explorer

To end the performance explorer session, use the End Performance Explorer (ENDPEX) command.

The End Performance Explorer (ENDPEX) command performs the following actions on the collected data:

• Places the collected data in files QAYPExxx in the library that you specify. Use OPTION(*END) and DTAOPT(*LIB) to do this. The database member name for all the QAYPExxx files uses the session name as the default unless you specify a name for the DTAMBR parameter. You can specify RPLDTA(*NO) to erase data that was collected using this session name or RPLDTA(*YES) to add the collected data to the existing data. Unless you are a very sophisticated user, use RPLDTA(*NO).
• Places the collected data into a single IBM-defined file. Use OPTION(*END) and DTAOPT(*MGTCOL) to do this. Typically, you would use *MGTCOL only under the direction of an IBM^® service representative. Specifying the *MGTCOL value on the DTAOPT parameter saves the collection information into a management collection object. The management collection object option should be used only if the data is going to be shipped to IBM. The performance tools can analyze only the database files.
• Discards the collected data. Use OPTION(*END) if you want to save the data or DTAOPT(*DLT) to discard any collected data. You do this when you determine the collected data cannot be used. For example, one of the suspected jobs did not start as expected. If you choose the *DLT option, the collected performance data for the session is never saved.
• Suspends the collection session but does not end it. Use OPTION(*SUSPEND) to do this. You can later start the data collection again by issuing the STRPEX command with OPTION(*RESUME) for the specific session ID.
