  * 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
