PM77266: A workspace conflict causes containers to not start.

APAR status

• Closed as program error.

Error description

• During concurrent starts of containers that are hosted on
  WebSphere Application Servers, a workspace conflict causes the
  container to not start.
  
  The following workspace conflict is displayed in the logs:
  
  [12/11/12 12:20:05:412 GMT] 00000000 WorkSpaceMast E
  WKSP0011E: Unable to create existing session id file

  talogComponentImpl_684_1352722805366\workspace\.workspace_
  --java.io.IOException: Access is denied.
  
  A trace shows that this conflict causes the deletion of the
  catalogservice.xml file:

  When the catalogservice.xml file is not found, the container
   defaults to using catalog.services.cluster property.
  If this property is not found, the container default to looking
  for the catalog server on the deployment manager (DMGR). If
  the DMGR is not hosting the catalog service, the request will
  timeout, with the following message:
  
  [12/11/12 12:21:05:582 GMT] 00000042
  ServerImpl    W   CWOBJ7300W: This server failed to bootstrap to
  a catalog server at the following address(es):
  dmgr.ibm.com:9809.  Will retry in 5000 ms.
  
  This causes the container to not start.
  

Local fix

• Workaround:
  
  On 7.1.1, the catalog.services.cluster is deprecated but still
  used as a backup.  Defining the catalog servers with this
  property will allow the containers to start.

  ****************************************************************
  Each container needs a session identification to access
  configuration information.  Containers starting on the same
  host were using the same identification and conflicting with
  each other.
  

Problem conclusion

• Each container now starts with a unique session identification
  based on its name and a time stamp.
