Question : Slowness of Weblogic server

After an update to the application on a Weblogic 9.2 MP2 system there is a feel of slowness of the server. How can we troubleshoot what can be the issue.

Answer : Slowness of Weblogic server

Hi snorkelfish,

This is the action list that I always use to monitor first when my application is going slow.
Thread - To check what the server is doing
JTA/Transaction - To check whether is there any stuck transaction.
Datasource - To check whether connection pool is enough and some usage statistic.
Queue (If you'are using) - To check how much message in the queue.
Server log - To check is there any exception happen.

Actually, this is not an easy task, it needs experience and if you have to solve in a short time you should ask support from product owner.

Here is some useful link to get start.
