Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Servers of WLM, or *
* workload management. *
****************************************************************
* PROBLEM DESCRIPTION: In a large environment, cluster *
* actions may take a long time *
* to complete. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Cluster operations such as starting or stopping a cluster
member in a large environment may take a long time to
complete. With this fix the Cluster / ClusterMgr MBeans
have been improved to perform better when the environment
consists of many Clusters / Cluster members. A hard number
can not be put on the quantity since variables such as number
of nodes, quality of hardware, number of applications, etc
all are part of the equation.
Problem conclusion
The problem was basically the Cluster MBeans would read
all of the XML config information for all of the clusters
even when all of the other clusters were not part of the
cluster specific action. So as a WebSphere cell grew
in size, the problem also grew in size.
Temporary fix
There is no workaround for this problem.
