When CA Symdump for CICS is started every Monday morning, all dumps in the PROTDMP file have been removed and the entire dump repository is empty.
When the PROTDMP file was created and initialized, the 'Automatic Purge of Dumps' was set to use the default value of YES. This field, in conjunction with the 'Automatic Purge Hold Days', which was set to the default value of 1, caused all dumps older than one day to be purged at startup.
CICS/TS executing in a z/OS environment with CA Symdump for CICS release 9.1 installed.
In order to prevent the PROTDMP file from being emptied automatically, you can either use the online SYMI transaction or run a batch job IN25DMPU to change the necessary settings to accomplish the desired result.
The following settings are recommended:
Using the online SYMI transaction:
If you choose to run the batch job IN25DMPU, please be aware of the following restrictions.
//MDFY EXEC PGM=IN25DMPU
//STEPLIB DD DSN=CAI.SYMDUM91.CABALOAD,DISP=SHR - your Symdump loadlib
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DSN CAI.SYMDUM91.PROTDMP - your existing protdmp file
OPT PURGE N - change the autopurge at startup from the current Y to N
OPT DYNAPURGE Y - change the dynamic purge of oldest dump from current N to Y
OPT HOLD 7 - hold dumps in the PROTDMP file for a minimum of 7 days. The oldest will be deleted if necessary
LIST ALL - this will list the dumps within the repository as well as the PROTDMP file statistics
OPT ALL - display all the options - the changes you've just made should display
Once the changes are made using either method, restart Symdump and the changes will be permanent.
