When the EVT0161 reaches 80% utilization or higher a message similar to the following is issued:

*TRACWARN - CAI.JOBTRAC.PROD.EVT0161  AT  88% FULL IN  10 EXTENTS

If maintenance is not done on a regular basis, the EVT area will eventually become full affecting Jobtrac processing.    

The TRACWARN message means that your current schedule space usage reached the threshold percentage (80% is the default).  The EVT area if allocated with secondary extents will take another extent until 100% full.  The EVT area is the current active schedule.  It is dynamic and changing as events are submitted, tracked, completed, and moved to archives. Loading a schedule adds events to the current schedule.  When archive job GJTRJARC runs it marks the events as archived, removing them from the active view.   When GJTRJPRG runs it removes jobs flagged as archived.                         

To maintain the EVT area and keep it from filling up, run the archive job GJTRJARC followed by a periodic run of purge job GJTRJPRG.   The archives should run every day to clean up the current scheduler, however the GJTRJPRG can run on a weekly basis.   When running archives it is highly recommended to include parm CLEAN. This will removes old, missing event, and extension records.  There will be no impact to the active workload.   Below is sample job to clean up the EVT area:                                 

//GJTRJARC EXEC PGM=GJTRJARC,PARM='ARCH,ALLC,CLEAN'                           

//STEPLIB     DD  DSN=JOBTRAC.CAILIB,DISP=SHR 

//                 DD  DSN=DATACOM.CUSLIB,DISP=SHR                           

//                 DD  DSN=CATACOM.CAAXLOAD,DISP=SHR                    

//SYSPRINT   DD  SYSOUT=*                                                      

//SYSTERM    DD  SYSOUT=*                                                      

//SYSMDUMP  DD  SYSOUT=*                                                     

//SYSUDUMP  DD  SYSOUT=*                                                     

//IPLPRINT     DD  SYSOUT=*                                                      

//JOBTRACx   DD  DUMMY               <==change     'x' is the Jobtrac token        

NOTE:                                                                       

C Selects only completed events that have no successors waiting (default)    

ALLC selects all completed events, regardless of the successors' status.     

CLEAN removes old, missing events, and orphaned event-related table records.                                                                     

Job should complete with RC=00.  

After the GJTRJARC completes the GJTRJPRG should be run.

Below is a sample of the GJTRJPRG (specify the values for the keywords appropriate for your site).

//GJTRJPRG EXEC PGM=GJTRJPRG,

//               REGION=4096K

//STEPLIB     DD DSN=JOBTRAC.CAILIB,DISP=SHR

//                 DD DSN=DATACOM.CUSLIB,DISP=SHR

//                 DD DSN=DATACOM.CAAXLOAD,DISP=SHR

//SYSPRINT  DD SYSOUT=*

//SYSTERM   DD SYSOUT=*

//SYMDUMP  DD DUMMY

//JOBTRACx  DD DUMMY                         <==change     'x' is the Jobtrac token        

//SYSIN        DD *

EVENT=*,GEN=5,DAYS=90,DELETE

STTDAYS=01

AUDDAYS=90

Below are the keywords that can be specified for GJTRJPRG.

EVENT={evname|prefix*|*}[,GEN=nnnn]|[,DAYS=nnnn]

[,DELETE|NODELETE][,DTFMT={A|I}][,FULL|SUMM]

[STTDAYS=nnn]

[AUDDAYS=nnnn]

[IPLDAYS=nnnn]

Additional information on GJTRJARC and GJTRJPRG can be found in the Jobtrac Reports, Maintenance and Recovery Guide.

NOTE:

It is recommended after running maintenance jobs to periodically perform a DBUTLTY DEFRAG to compress the index area.  The DEFRAG can be run at any time without any impact to Jobtrac.    See Article ID: 53438 for sample DEFRAG job.
