How can the -904 error be resolved?

Solution:

The Package PTADRVAC performs SELECTs from the following ACM Tables;

PTALT_ACM_0610
PTALT_SYSTBL_0610

These are both in Tablespace PTITSTBL.

The package was unable to perform it's SQL due to either of these tables being locked.

Changing the THREADS parameter of the BATPROC PARMLIB member from 2 to 1, should resolve this problem.

A THREADS parameter of 1, specifies that Batch Processor will use single-thread SELECT and SQL processing. This should eliminate the contention and allow the ssid0001 Install task to complete.

If object contention such as this occurs regularly when using Batch Processor, then consider setting THREADS(1) permanently, otherwise use THREADS(2) for improved performance.

THREADS(1) - single-thread processing
THREADS(2) - multiple-thread processing
