Hello,

My application deployed in the Weblogic instance is dead slow sometimes.
I'm using ADF 12c for application development
Weblogic Version: 12.2.1 in Windows Server 2012 R2
Java Vendor: Oracle Corporation
Jdk version : 1.8-65
Database : Oracle 11g

I don't know how to resolve this issue and couldn't yet understood the root cause for this.
So far, I managed to gather the following details.
• At this specific time, Managed server log file shows the following error related to Stuck Threads:

<Error> <WebLogicServer> <ManagedServer_1> <[STANDBY] ExecuteThread: '124' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <2c76372a-dbe4-4308-a06c-b9944a2d5d3a-0001b9dc> <1472636531716> <[severity-value: 8] [rid: 0] [partition-id: 0] [partition-name: DOMAIN] > <BEA-000337> <[STUCK] ExecuteThread: '117' for queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "630" seconds working on the request "Http Request Information: weblogic.servlet.internal.ServletRequestImpl@714bd487[GET /abcV3/adwwls/wls.ads]

Initially, Max Stuck Thread Time was 600 seconds. But, increasing the stuck threads time did not resolve my issue.

• I have set the following arguments at server start :
-Xms1024m -Xmx4096m -XX:NewRatio=2 -XX:SurvivorRatio=3 -XX:+AggressiveHeap
• The CPU usage of the server where Database is running :19% (Processes-19%, Services - 15%)
• The CPU usage of the server where application is running :97%
• Coming to the database side,
ps_txn table shows the count as : 7608

• Heap usage : 2228.21
• Active session : 29

Can anyone please help me in this regard? Any suggestions are most welcome.
Thanks in advance.
