Resolution

The QUEUE RETENTION clause of the SysGen SYSTEM statement specifies the time period in days that the system retains queues that are created dynamically. It was first introduced at r18.0.

Before that, it originally defaulted to 255 (never expires). r12.0 APAR CO82484 changed it to 170. Then optional APAR CS82781 allowed users to change it to whatever they wanted.

Due to the fact that this was a variable value and not simply an ON/OFF setting, this could not be implemented as an RHDCOPTF bit number.

Therefore, it was implemented as a clause on the SysGen SYSTEM statement.

The recommended setting is FOREVER or OFF, unless you were using CS82781 in the past, in which case, set it to the same value.
