The process requesting the key required exclusive, read-write locking authority , meaning no other process could be using the key, and no previous process left a stale, locked handle behind. Common Scenarios:
: Another system task or user has an "Exclusive" or "Shared" lock on the data set or specific key record, preventing your task from obtaining the necessary exclusive access.
START VSAM-FILE KEY IS GREATER THAN WS-KEY. READ VSAM-FILE NEXT. IF NOT END-OF-FILE READ VSAM-FILE RECORD INTO WS-REC UPDATE *> CRASH if the NEXT record's key is gone. mvsckey not found exclusive
Design batch jobs to detect key-lock failures and trigger a CKDS refresh if necessary.
If you rely on a cloud-based Key Management Service, temporary network timeouts can cause the local cryptographic subsystem to report that the key was "not found." Step-by-Step Troubleshooting Guide READ VSAM-FILE NEXT
You will need to temporarily disable ESET self-defense protection.
Then verify index-data consistency:
Use D ICSF,K,LABEL(label_name) to see if a lock exists.
Resolution of Error: mvsckey Not Found (Exclusive) Status: Resolved / Pending Priority: High If you rely on a cloud-based Key Management
