Over the last few months the customer experienced 2 abends (S813-04) in a DB2 Reorg job $DB2xyz using Tape Work files on CA-VTAPE. The DB2 Reorg job is run every Saturday morning in parallel with another DB2 Reorg Job $PRIxyz.  At the time of the abend there is a VTAPE Cache Full condition (message SVT1V0432E 0106,G73123,$PRIxyz ,Cache Full, Mount pending and will resume when Cache become available).  The CA-VTAPE Cache Full condition has occurred several times this year, and each time during the execution of the above DB2 Jobs (on 2/26, 4/23, 5/7, 5/21, and 6/4). The abend of job $DB2xyz happened on 2 occasions this year (5/21 and 6/4).

Release : 12.6

Component : VTAPE


Vtape is scratching some temporary volumes prematurely. 


The Vtape scratch/sync processing was occurring at the same time that the DB2 jobs were running, with CA1 using WRKFLS set to 'YES' (the default) allowing Vtape to scratch some temporary files/volumes prematurely.  The resolution is to either schedule the Vtape scratch/sync housekeeping jobs to occur at times when the DB2 jobs are not running, or else set CA1 WRKFLS to 'NO'.
