APAR status

  • Closed as program error.

Error description

  • In a clustered environment a list of possible servers is
    returned from the naming service for construction of  the
    resolve initial reference value.   Adding logic to check for a
    local reference in the list and using that local reference
    gives preference that the ejb will be dispatched locally.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of z/OS IBM WebSphere             *
    *                  Application Server V7.0, V8.0, and V8.5.    *
    ****************************************************************
    * PROBLEM DESCRIPTION: WebSphere Application Server for z/OS   *
    *                      does not prefer to resolve object       *
    *                      URLs, such as those used for naming     *
    *                      lookups, to a local server, if one      *
    *                      exists.                                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If one WebSphere Application Server for z/OS server is looking
    up a JNDI name in a cluster, the naming code uses an object
    URL to locate a member of the cluster to resolve the lookup
    to.  When resolving the object URL, the intent is to resolve it
    to a local server if possible, but the current code does not do
    this.  Instead, the object URL is resolved in sequential
    order, such that resolution to the first address in the URL is
    tried first, regardless of whether that address is local or
    remote.
    

Problem conclusion

  • The code that resolves object URLs was changed to prefer to
    resolve the URL locally, if possible.  Resolution is
    attempted first to all local address.  If the local address
    cannot be reached (for example, if the target server isn't
    started on the local machine), remote addresses in the URL are
    then tried.
    
    APAR PI13281 requires a change to documention.
    
    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:

    The following changes to the WebSphere Application Server
    Version 7.0 Information Center will be made available inr
    June, 2014.
    
    The topic "Application server custom properties for z/OS" will
    be updated to include the following description of the new
    custom property:
    
    protocol_iiop_resolve_object_url_local
    
    Specifies whether or not the application server should resolve
    object URLs to a server that is local to the LPAR, if possible.
    By default, the object URL is processed in order and the first
    server that can be reached is chosen.
    When this property is set to 1, any servers local to the LPAR
    are checked first and only if none of those servers are
    reachable will resolution be attempted to a remote server.
    
    Data Type  Integer
    Default  0
    Acceptable values  0 or 1
    
    APAR PI13281 is currently targeted for inclusion in
    Service Level 7.0.0.33, 8.0.0.9, 8.5.5.3 of WebSphere
    Application Server.
