I'm getting the following error message when trying to access the grid website for 11g OEM.
Backend WLS or EM application seems to be down
Does anyone have any clue as to why?
When i do a status on opmctl i get the following:
opmnctl status
Processes in Instance: instance1
---------------------------------+--------------------+---------+---------
ias-component | process-type | pid | status
---------------------------------+--------------------+---------+---------
ohs1 | OHS | 23452 | Alive

Backend WLS or EM application seems to be down
To resolve this error: Backend WLS or EM application seems to be down there are couple of things.
I have my database/agent/oms grid all on the same server. It was getting difficult to determine how to get this solved. I started to stop everything for a clear start.
I shutdown the database, then then agent and opmctl stopall . now nothing in the oracle account is running :
ps -aef|grep oracle
I finally figured out what the cause was.

This was quiet easy to resolve this : Backend WLS or EM application seems to be down
Apparently the OMS was down so we have to start it up.
Since I brought everything down, I followed the below steps to start everything back up.
* startup the database
* startup the listener
* startup the OMS using following commands:
opmnctl startall
/u01/app/oracle/product/11.2.0/Middleware/oms11g/bin/emctl start oms
/u01/app/oracle/product/11.2.0/Middleware/agent11g/bin/emctl start agent
Once I did this everything was ok. The website was back online and the login prompt showed up.
Thanks.
Hope this helps.

You can follow the same steps for when you get the following error message:
Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.
The only difference is, set the ORACLE_UNQNAME to following for different environments:
GRID:
export ORACLE_UNQNAME=/u01/app/oracle/product/11.2.0/gc_inst/WebTierIH1
AGENT:
export ORACLE_UNQNAME=/u01/app/oracle/product/11.2.0/Middleware/agent11g
This will help resolve it. Just set these values to the values that are appropriate for your enviornment.
