We believe the record hold table wait queue threshold exceeded user exit provided by APAR PJ39312 can be used to satisfy this request. If the WQTX user exit is enabled, a UXITC XP=WQTX is executed if the wait queue threshold has exceeded for a specific file record. If you want to use this user exit, routine UCCWQTX in cusr.cpy is expected to determine how you want to handle the request. you can either: (a) queue the request, (b) request that the ECB be exited, or (c) return to the caller with an error.
Please respond to the questions we posed on 11/26/19 so we can proceed with this RFE. Thank you.
APAR PJ39312 provided the record hold table wait queue threshold exceeded user exit. If the WQTX user exit is enabled, a UXITC XP=WQTX is executed if the wait queue threshold has exceeded for a specific file record. If you want to use this user exit, routine UCCWQTX in cusr.cpy is expected to determine how you want to handle the request. You can either: (a) queue the request, (b) request that the ECB be exited, or (c) return to the caller with an error.
Does this user exit provide you with the capability that you are requesting?
If not, are you asking for a new return on FIWHC and FINHC that is similar to the ENQC NOWAIT option? The ENQC NOWAIT option goes to a specified label if the resource is already held. A similar option on FIWHC and FINHC would go to a specific routine if the record is currently held. It would not be based on the number of ECBs on the hold queue.
Can you provide details about the application that you expect to use this capability that you are requesting? How would the application use it? For example, if a record is already held, what would the application do? Give an error response? Abort a utility? SERRC? Something else? The application might need to back out other database updates.
