Troubleshooting Tips
Consider the following when configuring and deploying a cluster configuration:
During the initial deployment of a cluster configuration, it is strongly recommended that the following debug flags be set in the wt.properties files on the master cache and all client caches hosts:
wt.cache.verboseServer=true
wt.cache.verboseClient=true
Monitor the server manager and method server log files and pay attention to Security Exceptions: Access denied and/or Server Unreferenced. Either of these could indicate a name resolution misconfiguration.
Using the JMX Console, you can monitor the method servers configured in the cluster. You can also use the Server Status page to see system activity.
Using the PTC System Monitor, you can monitor the method servers configured in the cluster.
For information about this monitoring tool, see Using the PTC System Monitor.
