While trying to run a backup on a database that has never had a problem, error messages appeared:
DB00101I - STARTED JOB-DBBACKUP1 NUMBER-11334 CXX=DBMUFPR1 MUFNAME=DBMUFPR1
CSV003I REQUESTED MODULE 01{{ Ý NOT FOUND
CSV028I ABEND806-04 JOBNAME=DBBACKUP1 STEPNAME=BKPSTEP4
The CXX showed that User Compression was turned on for a table, but the Compression Exit shows corruption: USER COMPRESSION - YES(01{{ Ý.Å)
Release: All supported releases.
The cause is currently unknown, but there are several diagnostics to perform, after which a support case should be opened.
If you have determined that nothing should have changed with this database definition, you have two options:
Note that if you reload the CXX data from a backup and if this is an active database, your record counts could now be incorrect, and you should run a DBUTLTY RETIX DBID=###,AREA=xxx,KEYNAME=*SETR command to recount the records in each area.
