Q. Why do we get error when we run “opmnctl status” from “$INST_TOP/ ora/ 10.1.3/ opmn/ bin” where as $ADMIN_SCRIPTS_HOME/adopmnctl.sh works ?
For those who are new to Oracle Apps R12 or OPMN
ORACLE_HOME in application tier in Applications R12
Similar to Oracle Applications 11i, there are two ORACLE_HOMEs (but of version 10g) on application tier (three in total including database)
i) 10.1.3 (10g R3) for Web-Apps Tier (HTTP, OC4J – oacore, oafm, forms)
ii) 10.1.2 (10g R2) for forms & reports server

What is opmnctl/adopmnctl ?
OPMN - Oracle Process Manager & Notification Server is component in Oracle Application Server (10g) to manage (start/stop/status) Application Server components (HTTP, OC4J)
adopmnctl - is wrapper around opmnctl to manage application server (10g R3 & 10g R3) in Oracle Applications (EBS) R12 . More information here
.
What is INST_TOP in Oracle Apps ?
INST_TOP denotes new TOP in Apps R12 INSTANCE_HOME, more information here . INSTANCE_HOME contains scripts, log and configuration files .
.
Now back to question Why do we get error when we run “opmnctl status” from “$INST_TOP/ ora/ 10.1.3/ opmn/ bin” although we get output on running $ADMIN_SCRIPTS_HOME/ adopmnctl.sh
When you run opmnctl status from $INST_TOP/ora/10.1.3/opmn/bin you get error like below
$ ./opmnctl status
Error reading opmn.xml
Message:{$INST_TOP/ora/10.1.2/opmn/conf/opmn.xml (No such file or directory)}
Filename:{$INST_TOP/ora/10.1.2/opmn/conf/opmn.xml}
FileContent:{}
.
This is because when you run “opmnctl status” from $INST_TOP/ora/10.1.3/opmn/bin, opmnctl executable picks up OPMN config file (opmn.xml) from $ORACLE_CONFIG_HOME/opmn/conf/opmn.xml and $ORACLE_CONFIG_HOME by default is set to 10.1.2 ORACLE_HOME .
It is still possible to display status using $INST_TOP/ora/10.1.3/opmn/bin/status but first set $ORACLE_CONFIG_HOME to 10.1.3 (This can be done by executing 10.1.3 environment file i.e. $INST_TOP/ora/10.1.3/$SID_$hostname.env )
.
Why don’t you get above error by running $ADMIN_SCRIPTS_HOME/ adopmnctl.sh ? adopmnctl.sh calls $INST_TOP/ora/10.1.3/$SID_$hostname.env and sets $ORACLE_HOME and $ORACLE_CONFIG_HOME to 10.1.3 related executable and configuration files. adopmnctl.sh is correct script to manage services (start/stop/status) controlled by OPMN in R12
