Abstract
Takes long time to start dmgr when a lot of clusters are
configured.
Download Description
USERS AFFECTED:
WebSphere Application Server 5.0 users of Workload Management, Network
Deploymnet and the Deployment Manager.
PROBLEM DESCRIPTION:
The performance of the Deployment Manager is slow when it is started.
RECOMMENDATION:
When the Deployment Manager is started, if there are numerous clusters
configured, the startup process will be slowed by approximately 40 seconds
per cluster.
PROBLEM CONCLUSION:
In the ClusterMgr MBean code, which is loaded and started in the
Deployment Manager when the Deployment Manager is started, invokes an
MBean call itself that was not scoped to just the Deployment Manager
process. The fix to the problem was scoping the ClusterMgr MBean
invokation on another MBean to just the DMgr process. Otherwise ,the MBean
invokation was sent out to the node agent process's as well, thus taking
longer to complete then was necessary.
