Defining diagnostic snapshot log streams

For optimal performance of the Incident Log task, it is recommended that your installation define operations log (OPERLOG) and logrec log streams for the CEA component of z/OS®. Doing so allows the system logger component to determine the storage characteristics for storing diagnostic snapshots.

How to check if this step is done

To display the OPERLOG logstream, enter the following command: 
D LOGGER,L,LSN=SYSPLEX.OPERLOG
Figure 1 shows the expected results:

If this step is not already done

To create the log streams, you can use a batch job like sample job CEASNPLG, which is supplied by IBM® in SYS1.SAMPLIB(CEASNPLG). The CEASNPLG job deletes and redefines CEA diagnostic snapshot model log streams, using the IBM utility program, IXCMIAPU. For information about the IXCMIAPU utility, see z/OS MVS Setting Up a Sysplex.
