APAR status

  • Closed as program error.

Error description

  • If there is a time delay in obtaining Dmgr connection or
    communication, RMI communication threads from Managing server
    pile up causing excessive creation of threads.  An optimization
    is required in JMXDelegate to eliminate the periodic
    conversation with Dmgr as this is done only in a cluster
    environment to obtain the cluster name.
    
    
    
    Users Affected: Potentially all WebSphere platforms running
    ITCAM for Application Diagnostics.

Problem summary

  • ****************************************************************
    DESCRIPTION:
    ITCAM Data Collector connects to the Websphere Deployment
    manager to get the status of cluster members and also to obtain
    the statistics like Database connection pool max size.
    
    This connection sometimes causes the Managing server
    communication RMI threads to hang if the Dmgr is not reachable.
    
    This APAR removes the logic to contact Dmgr and obtains the
    necessary data through other means.
