Output Management Web Viewer

Issue/Introduction

We had an unexpected shutdown of the Web Viewer task.  Not an abend, but what appears to be a 'clean' shutdown in the middle of the day.

Environment

  • Output Management Web Viewer for USS 12.1
  • z/OS UNIX System Services
  • Apache Tomcat®

Cause

Insufficient heap size. java/lang/OutOfMemoryError

Resolution

Database problems with many error messages. There have been no problems at all since the Heap Size was increased in the Tomcat task. 

Set  IJO="$IJO -Xms1024m -Xmx6144m"  (it was 4096m).
