To determine what value you have set for the QCODE in SC00OPTS, in each CICS region, issue the command DBUT M=SC00OPTS +8 OR in CA Ideal,
enter @I$SCF PGM=SC00OPTS OFF=8
In the following example, the QCODE is set to B.
000C1BD8 +0008 C2404040 40404040 00000000 00C10418 *B .....A..* 000C1BD8
Per CA IPC Implementation Guide: How to Modify the SCF Static Options
QCODE: A single byte that ensures that enqueue names are unique across systems. Code a single character without quotes or use the format C'x'.
Note: Before you change this value, make sure all affected CICS systems and batch jobs are not running. If they are running, the library can become corrupted.
