APAR status

• Closed as program error.

Error description

• Customer had a need to update the Clusters "Server read/write
  timeout retry count" (serverIOTimeoutRetry in plugin-cfg.xml).
  Customer determined that when they did this, that the plugin
  generation failed with a PLGC0018E: An exception occurred while
  reading the server cluster configuration for cluster
  <clustername>.
  

Local fix

• By examining the cluster.xml customer determined if they did
  NOT enable the "use cluster address" and fill at least the
  cluster address name with a dummy value, then save and disable,
  the cluster.xml would enter the following:
    <clusterAddress xsi:nil="true"/>
  
  This seems to cause the plugin generation to fail, once
  customer enabled and entered the dummy information, and
  disabled it, then the clusterAddress line disappears and this
  appears in it's place:
  <clusterAddressProperties xmi:id="
  ClusterAddressProperties_1403018039315" waitForContinue="false"
  connectTimeout="0" extendedHandshake="false" maxConnections="-1"
  serverIOTimeout="900"/>
  
  This does not cause the web server plugin generation to fail.
  It was to set the serverIOTimeoutRetry value in the plugin,
  which did seem to update the plugin to the applications
  requirement of "0":
     <ServerCluster CloneSeparatorChange="false"
  GetDWLMTable="false"
  IgnoreAffinityRequests="false" LoadBalance="Round Robin"
  Name="WASC3"
  PostBufferSize="0" PostSizeLimit="-1"
  RemoveSpecialHeaders="true"
  RetryInterval="0" ServerIOTimeoutRetry="0">

  ****************************************************************
  After setting "Server read/write timeout retry count"
  (serverIOTimeoutRetry in plugin-cfg.xml),the plugin
  generation fails with a PLGC0018E: An exception occurred while
  reading the server cluster configuration for cluster
  <clustername>.
  

Problem conclusion

• The generation code was attempting to use an option value
  before checking to see whether it was set or not. Modified
  code to check to see if set before attempting to use the value.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4.  Please refer to the Recommended Updates
