History records for the CA 11 JHF601 are retained via the mutually inclusive installation options of MAXDAY and MINCNT. The following run of a MANT cycle checks the MAXDAY and MINCNT for each job to determine if there are history records to be purged. If a job's history retention is not met during a MANT run, the JHF601 potentially grows in size.
The SET2PURG function is useful in purging history records for job that no longer run, causing their records to be retained. This option is not designed to perform normal maintenance of the JHF601. Once the SET2PURG indicator has been set to ‘YES’, the following run of a MANT cycle deletes the history record for that job.
To change the SET2PURG flag online, select the JUPD function from the CA 11/ISPF menu. Next, choose REP DATA: SET2PURG and mark the Control RECORD TYPE:C This flag is found only in the Control record. See example below:
OPTION ===> SCROLL- PAGE
Jobname : MYJOBA Record Type : C Profile :
PROD Date : RRUN Date : Remote:
PROD Time : RRUN Time :
Rep Data : SET2PURG=YES
To change the SET2PURG flag for multiple jobs in batch, use the U11OBD program as shown below:
//STEP1 EXEC PGM=U11OBD,PARM='(profile)'
//STEPLIB DD DISP=SHR,DSN=CA11.CAL7LOAD
//RMSRPT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSIN DD *
