R12.2 Adding server to Weblogic
In R12.2 with Weblogic now playing a huge role as well as java also creating resource heavy processes you will eventually run into a situation where you want to add servers to Weblogic. I'd actually recommend adding at least one more oa_core server as this is the one we've noticed is causing most of the issues.
Some checks and background #
Oracle recommends up to 150-200 concurrent users per JVM of size 2 GB. You can use theto find the current value but you should track this over time to give you an indication of how many users are in the system.

Adding Server #
Add oacore_server2 via command line:
perl $AD_TOP/patch/115/bin/adProvisionEBS.pl ebs-create-managedserver \ -contextfile=$CONTEXT_FILE \ -managedsrvname=oacore_server2 \ -servicetype=oacore \ -managedsrvport=7205 \ -logfile=/tmp/addMS_oacoreserver2.log
Start the new managed server as follows:
$ADMIN_SCRIPTS_HOME/admanagedsrvctl.sh start oacore_server2
Added details of the newly added managed server into the OHS configuration files mod_wl_ohs.conf and apps.conf via command line as below:
perl $FND_TOP/patch/115/bin/txkSetAppsConf.pl \ -contextfile=$CONTEXT_FILE \ -configoption=addMS \ -oacore=testserver.example.com:7205 perl $FND_TOP//patch/115/bin/txkSetAppsConf.pl \ -contextfile=<CONTEXT_FILE> \ -configoption=addMS \ -oacore=<host>.<domain>:<port> \ -oafm=<host>.<domain>:<port> \ -forms=<host>.<domain>:<port> \ -formsc4ws=<host>.<domain>:<port>
Bounce the apache server:
sh $ADMIN_SCRIPTS_HOME/adapcctl.sh stop sh $ADMIN_SCRIPTS_HOME/adapcctl.sh start
