Local fix

• If the server is receiving IIOP requests from a WebSphere for
  z/OS 6.0.2 server, ensure APAR PK84457 is applied on the 6.0.2
  server.

  ****************************************************************
  * PROBLEM DESCRIPTION: WebSphere Application Server for z/OS   *
  *                      terminates with ABENDDC3/ABENDSDC3,     *

  ****************************************************************
  A misbehaving or defective CORBA client could send two
  concurrent IIOP requests with duplicate request IDs. This is a
  violation of the CORBA specification. If a client sends
  multiple requests on the same connection with the same request
  ID, it can lead to the controller region terminating with
  ABENDDC3/ABENDSDC3, reason code 000C0006.
  
  PK84457 fixes a potential cause of duplicate request IDs in
  WebSphere Application Server V6.0.1.
  

Problem conclusion

• WebSphere Application Server for z/OS will now check for
  duplicate request IDs on a connection. If an incoming request
  specifies the same ID as an already active request, the new
  request will receive an error response with minor code
  C9C26A4C and the connection will be aborted.
  
  APAR PM10291 requires changes to documentation.
  
  NOTE: Periodically, we refresh the documentation on our
  Web site, so the changes might have been made before you
  read this text. To access the latest on-line
  documentation, go to the product library page at:
  
  http://www.ibm.com/software/webservers/appserv/library
  
  Changes to the WebSphere Application Server Version 7.0
  Information Center will be made available in
  October, 2010.
  
  The topic "Error minor codes" will be updated to include
  the following description of the C9C26A4C error minor
  code:
  
  C9C26A4C
  
  Explanation:
  The server received a GIOP request with a request ID that
  is already in use by an active request on this connection.
  This means the IIOP client is sending multiple concurrent
  requests with the same request ID, which is a violation
  of the CORBA specification.  The duplicate request fails
  with this exception.  The server aborts the connection.
  
  User response:
  Look for errors in the IIOP client that is sending
  duplicate request IDs.
  
  APAR PM10291 is currently targeted for inclusion in Service
  Level (Fix Pack) 7.0.0.13 of WebSphere Application Server V7.0.
