ACVO
Explanation
The transaction routing program in the terminal-owning region issued an ISSUE PREPARE request and received either a nonzero return code or a response which violates CICS transaction routing protocols.
The return code is located in TCASPRC and the response is located in TCASPSN1.
System action
The task is abnormally terminated with a transaction dump and an exception trace entry.
User response
Use the transaction dump to determine whether the problem is caused by the return code or the response. If terminal control was unable to process the request, the abend may occur when:
-
The program in the connected region terminates abnormally. In this case, determine the reason why the program has abnormally terminated.
-
The session has failed.
Otherwise the distributed application programs may have violated APPC conversation protocols.
