Updated version of AL7BKUP to avoid leaving the LOCKs in place.

Products

• CA-11

Issue/Introduction

The AL7BKUP job contains LOCK and UNLOCK statements in the DBUTLTY step.

If for some reason the BACKUP job does not complete successfully (i.e., the BACKUP portion failed) then the UNLOCK doesn't execute leaving the LOCKs in place. Please utilize this version of the AL7BKUP job to prevent this from happening.

Resolution

The AL7BKUP job contains LOCK and UNLOCK statements in the DBUTLTY step.

If for some reason the BACKUP job does not complete successfully (i.e., the BACKUP portion failed) then the UNLOCK doesn't execute leaving the LOCKs in place. This is because the LOCK/BACKUP/UNLOCK are in the same DBUTLTY step.

An adjusted version of AL7BKUP, which is included below separating the LOCK and BACKUP statements into one step, and the UNLOCK statements into a second step with a COND=EVEN which will allow it to run regardless of what happens prior.

Please utilize this version of the AL7BKUP job to prevent this from happening. The permanently updated version of this is upcoming and will be available later for CA 11.
