Our ADF Application running on weblogic 10.3.5 is bit slow in operation. This is the only application deployed in this server machine.
The server specification is below -
Intel Xeon Processor @3.0GHZ
RAM 5 GB
Windows Server 2008 Standard Edition Service Pack 2 64 Bit
Weblogic is using bundled JDK 1.6_24 - 32 Bit JVM.
We already have tuned our Application. We want to tune weblogic more.
Sometimes, it takes time to load UI & communicating with database. Our application EAR file is of 28 MB.
How can we allocate more memory for weblogic ?
More memory will (probably) not resolve your issue.
"Sometimes, it takes time to load UI & communicating with database."
Take a look at the queries that are used, in the UIs that load slow.
To increase the memory, you can use setDomainEnv and set the Xmx and Xms to a higher value or set (and use) the USER_MEM_ARGS parameter.
Some example are given here: http://middlewaremagic.com/weblogic/?p=6388
You can follow this link to get into weblogic tuning details :
Firstly you will have to identify the probable areas where the application is getting slow. These can be lack of memory/cpu, high i/o, network congestion or db response. Depending on the responses you can tune your overall application deployment.
