Increment Advisor will not adjust thread count
Last updated on DECEMBER 11, 2017
Applies to:Oracle WebLogic Server - Version 10.3.6 and later
Information in this document applies to any platform.
Fixed version : 12.1.3
The Increment Advisor, which decides when to increase and decrease thread in self-tuning thread pool, sometimes behaves erroneously.
In some cases, you would see underutilized thread pool and the self-tuning thread pool does not have sufficient threads which could manage the workload at that point of time
In order to confirm this, browse to AdminConsole => <servername> => "Monitoring" TAB and "Threads" SubTab and you could see most of the threads in STANDBY state and still number of pending requests exists.
Note : The above messages are <DEBUG> messages and will only point out to "Suspicious conditions being hit".
This is to further confirm the faulty behaviour "Increment Advisor"
