Running backup once a week and writing to the same tape for a month. The following report only gives the current week:
// TLBL TAPEIN,'PSYS.EXPDALY.HIST',,,,,,2 // TLBL TAPEOUT,'PSYS.EXPDALY.HIST',,,,,,2
// EXEC EXPUTIL,SIZE=EXPUTIL
SUMMARIZE - INPUT(TAPEIN) - OUTPUT(TAPEOUT) - TYPE(CICSPERF) - INTERVAL(1 HOUR) -
COMPRESS(YES)
SUMMARIZE/COMPRESS is not doing a RESET.
TAPEIN and TAPEOUT should not be using the same DSN name
Example:
// ASSGN SYS001,280
// TLBL TAPEIN,’EXPCARC.BACKUP.OLD’
// ASSGN SYS000,281
// TLBL TAPEOUT,’EXPCARC.BACKUP.NEW’
After this runs, make TAPEIN ’EXPCARC.BACKUP.NEW’ and tape out a different name to accumulate the records.
