Increase oacore process in Oracle EBS 12.1.3

STEP1:

Take a backup of context file and opmn.xml file. a. /u01/inst/apps/<CONTEXT_NAME>/ora/10.1.3/opmn/conf/opmn.xml
b.$CONTEXT_FILE

STEP2:

Modify $CONTEXT_FILE as follows
From
<oacore_nprocs oa_var=”s_oacore_nprocs”>8</oacore_nprocs>
To
<oacore_nprocs oa_var=”s_oacore_nprocs”>16</oacore_nprocs>

Modify /u01/inst/apps/<CONTEXT_NAME>/ora/10.1.3/opmn/conf/opmn.xml file under oacore section as follows:
(<process-type id=”oacore” module-id=”OC4J” status=”enabled”
working-dir=”$ORACLE_HOME/j2ee/home”>)
From
<process-set id=”default_group” numprocs=”8″/>
To
<process-set id=”default_group” numprocs=”16″/>

STEP4:

Bounce Apache services, no need of autoconfig.  If your application services are already running, just reload the ocaore processes using adopmnctl.sh reaload command.
