IC88423: WMB V8.0 : ENABLING DEBUGGER CAN IMPACT DEPLOYMENT TIMES

APAR status

  • Closed as program error.

Error description

  • When the debugger is enabled for an execution group, the time
    taken for deployment of certain runtime artifacts can be
    impacted. This can be seen to occur when the user deploys
    large/complex XML or DFDL schemas to an execution group.
    The problem occurs because the JVM JIT compiler is unnecessarily
    disabled when the debugger is enabled.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere Message Broker V8.0.
    
    
    Platforms affected:
    z/OS, MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    When the debug port (the jvmDebugPort property of the
    ComIbmJVMManager object) is set to a non-zero value to enable
    flow debug using the WebSphere Message Broker Toolkit, the
    execution group JVM is configured to start in debug mode. The
    JVM debug mode options used at V8.0.0.0/V8.0.0.1 disable the
    JIT, which can impact deployment times of large/complex XML or
    DFDL schemas and other artifacts. However, disabling the JIT
    is unnecessary and not recommended at the JVM level supplied
    with WebSphere Message Broker.
    

Problem conclusion

  • WebSphere Message Broker has been modified so that the
    recommended JVM debug mode options are used.
