AEZD
Explanation
An attempt has been made to run a program defined as EXECKEY(USER) as part of a transaction defined as TASKDATAKEY(CICS). These attributes are incompatible and the transaction is abended. This incompatibility could occur as a result of the program definition being autoinstalled. See the Customizing with user exit programs and the Defining resources for more information about program autoinstall.
System action
The transaction is abnormally terminated. Message DFHAP1226 will show the incompatible program and transaction.
User response
Redefine and install a new definition either for the transaction with TASKDATAKEY(USER), or for the program with EXECKEY(CICS).
If this abend occurs when running a CICS transaction, a possible cause is that you are not using the CICS-supplied definition for the program. If you are using your own copies of CICS-supplied program definitions, they must be defined as EXECKEY(CICS).
