How to Increase min number of executable threads in Weblogic 10.3.0

Question

Hi,
I was trying to increase the Min number of executable threads using the following startup argument
"set USER_MEM_ARGS=-Dweblogic.threadpool.MinPoolSize=30" in startWeblogic.cmd. But doing so haven't increased the "execute thread total count" to the desired number when I verified it in console.
Kindly help me to configure this.
PS: Changing the configuration file (config.xml) is not recommended.
Thanks
Prasanth

In 10.3 usually work managers are used for this purpose. (http://download.oracle.com/docs/cd/E12840_01/wls/docs103/upgrade/compat.html#wp1117123)
You can use the 8.1 thread pool if you want (http://download.oracle.com/docs/cd/E12840_01/wls/docs103/perform/appb_queues.html#use81)
but generally work managers are the preferred way: http://download.oracle.com/docs/cd/E12840_01/wls/docs103/config_wls/self_tuned.html
Coming back to your original question:
"I was trying to increase the Min number of executable threads using the following startup argument "set USER_MEM_ARGS=-Dweblogic.threadpool.MinPoolSize=30" in startWeblogic.cmd. But doing so haven't increased the "execute thread total count" to the desired number when I verified it in console."
Can you add the option in the setDomainEnv file, located in the ${DOMAIN_HOME}/bin directory, for example,
@REM *************************************************************************
set WL_HOME=C:\bea\wlserver_10.3
for %%i in ("%WL_HOME%") do set WL_HOME=%%~fsi
set BEA_JAVA_HOME=C:\bea\jrockit_160_24_D1.1.2-4
set USER_MEM_ARGS=-jrockit -Xms512m -Xmx512m -Xgc:throughput -Dweblogic.threadpool.MinPoolSize=100
set SUN_JAVA_HOME=To check if it indeed shows the number of threads you can follow the steps presented here: http://m-button.blogspot.com/2009/02/tuning-default-workmanager-on-weblogic.html
