Issue/Introduction

When analyzing RC/Migrator for Db2 for z/OS (RCM) strategies concurrently, this message could occur:

It is not always obvious what other strategy is in use, what causes the message.

Resolution

When running multiple batch jobs to analyze RC/Migrator strategies this message can occur.

RMA132E STRATEGY IS CURRENTLY BEING ACCESSED BY ANOTHER USER

The processing that drives this message issues a z/OS ENQ coded as follows:

ENQ (QNAMEM,RNAMEM,E,20,SYSTEMS),RET=USE

The QNAME is "MIGRATOR" and the RNAME is made up of 3 pieces of information:

RNAME (20) = SSID (4), CREATOR (8), STRATEGY (8)

There are two ways to correct this:

1. Use different CREATORs on each LPAR, thus allowing unique resource names.
2. Stagger the starting of these jobs so they each run without contention.
