APAR status

  • Closed as program error.

Error description

  • URL-Alias is defined with a JNDI name at cell scope. Clusters
    was overwritten with the URL-Alias from the cell scope.
    

Local fix

  • add "-Dcom.ibm.ws.runtime.disableResourceReload=true" as a
    generic JVM
    argument on the server process

    * RECOMMENDATION:                                              *
    ****************************************************************
    When changes are detected to resource configuration documents,
    the WAS resource manager reloads resources at the scope(s) at
    which it detects changes to the resources.  In cases where
    changes are detected in wide-scoped resources (such as a cell
    or cluster), the resource manager's reload process rebinds
    resources in these definitions to JNDI.  If there are
    resources with the same JNDI name defined at a more immediate
    scope (such as a node or server), this can override the
    existing JNDI name binding for those resources, causing
    unexpected resource definitions in those nodes or servers.
    

Problem conclusion

  • A configuration setting has been added to prevent the
    resource manager from performing a partial reload of the
    resource configuration.  To enable this setting, add
    "-Dcom.ibm.ws.runtime.disableResourceReload=true" as a generic
    JVM argument on the server process.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.13 and 9.0.0.6.  Please refer to the
