Replacing existing transient data queue definitions

You can replace an existing transient data queue if certain conditions are satisfied.

About this task

All the following conditions must be satisfied before you can replace an existing transient data queue:
  • CICS® initialization is complete
  • The queue TYPE is the same as the existing definition
  • The intrapartition queue is disabled
  • The extrapartition queue is disabled and closed

Existing definitions cannot be replaced during a cold start of CICS. If you are using multiple groups, take great care to ensure that duplicate names do not exist. Duplicate names cause error messages to be issued. The duplicate definition is not used to replace the existing one.

You can use the following transactions and commands to inquire about, set, and discard transient data definitions after they have been installed:
  • CEMT INQUIRE TDQUEUE (or EXEC CICS INQUIRE TDQUEUE)
  • CEMT SET TDQUEUE (or EXEC CICS SET TDQUEUE)
  • CEMT DISCARD TDQUEUE (or EXEC CICS DISCARD TDQUEUE)
  • The CECI transaction
