Problem summary

    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V9.0                                 *

    * PROBLEM DESCRIPTION: Application servers created within an   *
    *                      existing profile are configured with    *
    *                      unexpected default initial and maximum  *
    *                      heap sizes.                             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When using the Administrative Console or administrative
    commands to create a new application server within a
    v9.0 profile, the configuration of the new server unexpetedly
    contains the default initial and maximum heap sizes for
    V8.5.5 rather than V9.0.
    For WebSphere Application Server V9.0, the default initial and
    maximum heap sizes for an Application Server are,
    respectively, 256M and 512M for the Adjunct and Control
    regions; 512M and 1024M for the Servant region.
    When necessary for pre-existing Application Servers, you can
    perform the following procedure to set the initial and maximum
    heap sizes. The procedure applies also to Node Agents and
    Deployment Managers.
    1. In the Administrative Console, select the target server
    to configure.
    For Application Servers
    Servers > Server Types > WebSphere application servers
    Select the server you want to work with -- for
    example, server1
    For Node Agents
    System Administration > Node Agents
    Select the Node agent you want to work with
    For Deployment Managers
    System Administration > Deployment Manager
    2. On the Configuration tab, under Server Infrastructure,
    expand Java and Process Management, and click Process
    Definition.
    For z/OS the following tasks must be performed for each
    of the regions (Control, Servant, and Adjunct) as applicable
    to each Application Server, Node Agent, and Deployment Manager.
    3. Under the Additional Properties section, click Java
    Virtual Machine.
    4. In the Initial heap size field, enter the initial heap size
    available to the JVM, in megabytes -- for example, 512
    5. In the Maximum heap size field, enter the maximum heap size
    available to the JVM, in megabytes -- for example, 1024
    6. Ensure the Generic JVM Arguments field does not contain JVM
    options that set the initial and maximum memory sizes, -Xms and
    -Xmx.
    7. Apply and Save the changes.
    The new values for the initial and maximal heap sizes are now
    set in the target server configuration.
    8. Restart the target server for the changes to take
    effect.
    

Problem conclusion

  • Apply APAR PI87963 to enable the Administrative
    Console and administrative commands to create Application
    Servers configured with the default initial and maximum heap
    sizes for V9.0, specifically:
    
        Region    Initial   Maximum
        ----------------------------
        Control   256 M     512 M
        Adjunct   256 M     512 M
        Servant   512 M     1024 M
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 9.0.0.6.  Please refer to the Recommended Updates page for
