MustGather: Cluster RippleStart problems on Versions 5.0, 5.1, 6.0, 6.1
 Technote (troubleshooting)
 
Problem(Abstract)
MustGather for problems with the IBM® WebSphere® Application Server ClusterRippleStart component. Gathering this information before calling IBM support will help familiarize you with the troubleshooting process and save you time.
 
Resolving the problem
RippleStart combines stopping and starting operations. It first stops and then restarts each member of the cluster. For example, your cluster contains three cluster members named server_1, server_2 and server_3. When you click RippleStart, server_1 stops and restarts, then server_2 stops and restarts, and finally server_3 stops and restarts. Use the RippleStart option instead of manually stopping and then restarting all of the application servers in the cluster.
If you have already contacted support, continue on to the component-specific MustGather information. Otherwise, click: MustGather: Read first for all WebSphere Application Server products.

RippleStart specific MustGather information

  1. Stop all servers and clear the entire logs directory.
  2. Set tracing of the Admin component for the dmgr, nodeagent and all cluster members for the cluster
    • V5.0 => Admin=all=enabled:WLM*=all=enabled:Cluster*=all=enabled
    • V6.0 => Admin=all:WLM*=all
    • Make sure the trace output Maximum File Size limit is large (20MB recommended) and Maximum Number of Historical Files is greater than 5.
    • See the appropriate Information Center for additional information on tracing.
