Workspace WebSphere Liberty
Created by Guest
Created on Jun 22, 2026

Terminate the Liberty server when a stop server request is received while MDB application has been running longer than the configured timeout value.

Backgrounds
Customer is migrating from WAS for z/OS traditional to WAS for z/OS Liberty. During the migration, many incompatibilities have been identified between WAS for z/OS traditional and WAS for z/OS Liberty. We understand that WAS for z/OS traditional and WAS for z/OS Liberty are different products; however, from the customer’s perspective, IBM recommends migration to WAS for z/OS Liberty, nevertheless mandatory functions are not implemented in WAS for z/OS Liberty, which is considered a functional regression by the customer. In particular, the customer places the highest priority on the ability to detect hung MDB applications.

Problem
If stop server request is received while MDB application is hanging, WAS for z/OS Liberty server never stopped. It lead the termination hang for WAS for z/OS Liberty server when stopping the server. In case of WAS for z/OS traditional, it has the capability to stop and restart a servant region when an MDB timeout occurs. 

Customer Request
Customer requests that the Liberty server to be terminated when a stop server request is received while an MDB application has been running longer than the configured timeout value. Currently, for Servlet applications, the Liberty server can be successfully stopped when a stop server request is received if the stopTimeout value in applicationManager is configured. The customer believes that similar behavior should be applicable to MDB applications, not only Servlet applications.
