Modifying the Logstream Dump Procedure CASFDUML

CA SMF Director provides a JCL procedure that is automatically executed when a switch command is issued for the logstreams. Procedure CASFDUML uses the CA SMF Director logstream interface as well as CA SMF Director to archive SMF data that has been recorded to the logstreams and to keep an inventory on a logstream basis by SMF ID.

If you want to change the started task name that is used or limit which SMF logstreams will be managed, you must modify user exit SMFLSTBL. A sample skeleton exit is provided in the sample library. Sample JCL to assemble and link this exit are provided in the sample library.

The default action for automatic dumping is to start the CASFDUML procedure for all logstreams that are actively recording SMF data, so if this is what you want to occur when the SWITCH SMF command is issued, you do not need to take any action with SMFLSTBL.

If the action needed is something else, you must take the following steps in this order:

1. Make any necessary changes to the SMFLSTBL sample program as needed by your data center. For more information about the SMFLSTBL user exit, see the Systems Programmer Guide.
2. Modify the sample JCL member LSTBLAL to your data center standards, submit it to assemble the SMFLSTBL exit, and link it.
3. If your CASFLOAD target library is in the link list, you must perform a Linklist Look Aside refresh. To do this, issue this command from the operator console:

   F LLA,REFRESH
   

   If your CASFLOAD target library is not in the system link list, the SMFLSTBL program that you assembled and linked must be copied to a data set in the system link list. Once the program is copied to a link list data set, perform a Linklist Look Aside refresh with the same command.

4. Disable and reenable the automatic dumping exit intercept. To do this, you must run the CAS9 procedure twice. Run it the first time with this statement to disable the existing automatic dump procedure:

   PRODUCT(CA-SMF AUTODUMP) VERSION(SFC6) INIT(SMFINIT) PARM(DISABLE)
   

5. Run it again with this statement to re-enable the intercept:

   PRODUCT(CA-SMF AUTODUMP) VERSION(SFC6) INIT(SMFINIT) PARM(ENABLELS,LX=name)
   

   where name is the name of your exit. For example, the name is SMFLSTBL if you have not renamed the sample exit.
