How to increase oacore/jvm processes in R12.1.3

Below are the steps to increase oacore process:

STEP1: Take a backup of context file and opmn.xml file. 

a. $INST_TOP/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">1</oacore_nprocs>

To

<oacore_nprocs oa_var="s_oacore_nprocs">2</oacore_nprocs>

STEP3: Modify $INST_TOP/ora/10.1.3/opmn/conf/opmn.xml as follows

$INST_TOP/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="1"/>

To

<process-set id="default_group" numprocs="2"/>

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.

                                                        OR 

Bounce the Application services for safe side.
