Logical message recovery

Logical messages created with a disposition of PAGING are kept in CICS® temporary storage between creation and delivery. BMS constructs the temporary storage queue name for a message from the 2-character REQID on the SEND commands, followed by a six-position number to maintain uniqueness. If you do not specify REQID, BMS uses a value of two asterisks (**).

Temporary storage can be a recoverable resource, and therefore logical messages with a disposition of PAGING can be recovered after a CICS abend. In fact, because CICS bases the recoverability of temporary storage on generic queue names, you can make some of your messages recoverable and others not, by your choice of REQID for the message. The conditions under which logical messages are recoverable are described in the CICS Recovery and Restart Guide.

Routed messages are eligible for recovery, as well as messages created for your principal facility. We explain routing in Message routing.
