Issue/Introduction

Periodic "RMOCPP05 WAITING FOR CHECKPOINT" messages are issued, and the system hung.

 

Environment

Deliverâ„¢
Output Management Deliverâ„¢ for z/OS

Resolution

In this instance, Workload Manager (WLM) was in use, and Deliver (RMO) was a victim of WLM.  WLM was limiting the service class that RMO runs in. 

There were many people using the CICS integrated test environment, and WLM was giving that activity all of the cycles. When this was resolved the messages no longer appeared and the system did not hang.
