CA SymDump

TECH TIP: IN25DMPU allows you to modify the options of an existing PROTDMP file created for CA Symdump for CICS.

When creating a PROTDMP file for use with CA Symdump for CICS, the initial options are set using program IN25INIT; it cannot be run against a previously initialized file.   IN25DMPU can be used against an existing PROTDMP file should you wish to change these initial settings.  You can use this utility to list the file statistics, the options, and to modify any of these options set with IN25INIT when the file was originally created.

For example, IN25INIT sets the default number of duplicate dumps that can be written to the PROTDMP file to 1.  IN25DMPU allows you to override this default. 

 

Duplicate dump suppression is controlled by two options:

  • SUPPRESSD=Y or N which specifies whether or not dump suppression is in effect; the default is N.
  • SUPPRESSL=001 - 999 the dump suppression limit.  The default is 001 and must be set with a 3 digit number as shown.  SUPPRESSL only takes effect when SUPPRESSD is set to Y 

 

Once the PROTDMP file is created and assuming you want to change the duplicate dump suppression values they can always be modified using IN25DMPU.  If this is the primary PROTDMP file used in the CICS region, CA Symdump must be inactive when this job is run.  Otherwise, if the file is not in use by CA Symdump for CICS, this job can be run at any time.

 

The following JCL changes the options of SUPPRESSD to Y and the SUPPRESSL value is increased to allow 10 duplicate dumps. The LIST ALL displays the file statistics as well as any dumps that exist in the file.  OPT ALL displays the options that were set or modified.
