Issue/Introduction

DB13111E - BASE <dbid> IS OPEN FOR UPDATE IN MULTI-USER, RESET REJECTED

The Multi-User Facility (MUF) indicates that a database identifier (DBID) is open for update in a CICS region, despite the CICS region being closed or cycled. Attempts to issue a RESET command for the database directory (CXX) via DBUTLTY are rejected with message DB13111E. System monitoring tools may show active RunUnits for the of the CICS region even when no active tasks are visible within CICS.

Cause

This issue occurs when the Datacom CICS Services termination process fails to execute during CICS shutdown. The technical trigger is typically the absence or commenting out of the program DCCOCPR in the CICS Program List Table for Shutdown (PLTSD). When DCCOCPR is not invoked during shutdown, Datacom CICS Services cannot communicate the termination of active RunUnits to the Multi-User Facility (MUF), leaving "orphaned" connections that prevent other batch jobs from accessing the database for update.

Resolution

1. Verify PLT Configuration: Review the CICS Program List Table source for both Startup (PLTPI) and Shutdown (PLTSD).
2. Update PLTSD: Ensure that program DCCOCPR is defined in the PLTSD. This program is responsible for the orderly termination of Datacom CICS Services.
3. Update PLTPI: Ensure that program DCCOCPR is defined in the PLTPI to automate the connection to the Multi-User Facility (MUF) during CICS initialization.
4. Clear Orphaned RunUnits: If the PLT configuration is corrected but orphaned RunUnits persist in the current MUF session:
   • Perform a MUF failover to a Shadow MUF or cycle the MUF region to clear the internal RunUnit tables.
   • Verify that the DBID is no longer marked as open for update by issuing a COMM STATUS command to the MUF.

Additional Information

Official Message Documentation:

• Message Text: DB13111E - BASE <dbid> IS OPEN FOR UPDATE IN MULTI-USER, RESET REJECTED
• User Action: The RESET function cannot be processed if the database is currently open for update in the MUF. Ensure all regions (CICS, Batch, etc.) using the database for update are closed before attempting the RESET.
