IDAEDB2P05 - User DB2 plan-exit program for current RUN cannot be loaded

Reason:

The user DB2 plan-exit program name is initialized through the command SET ENV DB2PLAN-EXIT loadname.

The program is always employed with transactions that use the CA Ideal DB2 RCT exit program @IADRCTX. Possible reasons for the error include:

The user inadvertently switched to a transaction that uses the CA Ideal RCT exit when, in fact, the user intended to use a transaction that does not employ the CA Ideal RCT exit.
The program loadname specified in the command is misspelled.
The program specified by the command is unavailable to the current environment.

Action:

Verify that the program is executed under the CICStransaction-ID if being run online. Make appropriate changes to commands and programs to assure that the correct CICS transaction is invoked at the point where the error occurred.
Verify the SET ENV DB2PLAN-ID command was correctly entered before the RUN, and make corrections if necessary.
Make certain that the correctly spelled program set in the command is available to the environment. In CICS, this can be caused by an inappropriately issued NEWCOPY operation. In all available environments, this can be caused when the program specified is not in the concatenation of available load-libraries.
