ATB062I
LOGICAL UNIT luname FOR TRANSACTION SCHEDULER schedname HAS BEEN TERMINATED DUE TO ALTERNATE APPLICATION TAKEOVER.

Explanation

An application outside of Advanced Program-to-Program Communication (APPC) tried to open an access method control block (ACB) that was originally opened by APPC. This causes the system to close the logical unit (LU) associated with the ACB.

The fields in the message text are:
luname
The name of the logical unit that the system closed.
schedname
The name of the transaction scheduler that was using this logical unit.

System action

The system continues processing.

Operator response

Notify the system programmer. Enter the SET APPC command to re-activate this logical unit if necessary.

System programmer response

This problem may be due to a security violation. Only authorized programs defined to RACF® can open an ACB that was originally opened by APPC.
