M204.0590  Share-dasd enqueueing inactivated​,​ FPL of file token is on a read-only device

SHARE-DASD enqueueing protects a file from concurrent access by multiple Model 204 runs. Write access to the disk containing the indicated file is required to activate SHARE-DASD enqueueing. Since the file is being opened for READ-ONLY access, the OPEN will be allowed, but unexpected results may occur.

Response: Notify your system manager.

System manager response: Changing the access mode of the disk containing the indicated file to READ/WRITE will prevent inconsistencies between multiple runs accessing the file concurrently.
