Issue/Introduction

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)

 

 

 

Resolution

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.
