EXEC CICS LINK interface messages

When you call the adapter operation functions START and STOP from an application program using EXEC CICS LINK, the resulting messages are written to both the system console and a transient data queue (TDQ) named CKQQ.

When the application program returns from the LINK, it can read back the messages by repeating EXEC CICS READQ TD QUEUE(CKQQ) until the queue is empty. The following restrictions apply:
  • The TDQ queue name is CKQQ and cannot be changed. The definition for CKQQ is supplied in the CICS® CSD group DFHDCTG.
  • The queue is not cleared before it is written to.
  • If you have more than one application writing to the TDQ, the messages are not serialized. The calling programs must serialize themselves.
  • The same set of messages is also displayed on the system console.
