Well, EPM is strange at
times. It gives you this weird errors and then it tells you the probable causes
for the error. Now, I have no issue with probable causes of error. But if I
have to google an error just to understand what it means, somewhere something is
seriously wrong.
The other day I was trying to
access my Workspace page, when I got this huge mumbo jumbo error from something
called as Weblogic Bridge Message ( I must admit, it sounds kinda cool). The
error is as follows:-
Failure of server APACHE
bridge:
No backend server available for connection: timed out after 10 seconds
or idempotent set to OFF or method not idempotent
Now the catch is that, with so much explanation, I first got
stumped at idempotent. The last idempotent I heard was in college where we had
an idempotent matrix( a matrix which when multiplied by itself gives itself).
So you see the error message is useless in understanding the issue. Although
the error message is useless, the first half does give a neat idea on what
might be the issue. “No backend server
available for connection.”
So I decided to check, if the Middleware home is accessible
or not. Generally, this would be running on port number 7001 by default.
When I checked the Oracle Middleware home in a browser on
path 7001, it shows the classic web error.
“The page can’t be displayed.”
Now, we are getting somewhere. So I decided to start the
Oracle Weblogic server once.
Now, to fix the issue, you will need to start the Weblogic
server.
This can be done by running the following batch file/shell
script:-
{MIDDLEWARE_HOME}\user_projects\domains\EPMSystem\startWebLogic.bat
If you check out the above snapshot, you will see that
WebLogicServer is now up and running.
Now, we check the Oracle Fusion Middleware page on port
number 7001 and it opens up as shown in the below snapshot.
My Workspace page also opens up as shown below.
