Greetings to All!

I am totally new to Oracle...TOTALLY new. Right out the gate, I experienced the problem of not being able to start the
DBCONSOLE immediately after installing Oracle 11G R2 onto my Windows 7 box. Here is what I have ran from the command line:


Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Users\sandifer>emctl start dbconsole
Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.

C:\Users\sandifer>SET ORACLE_HOSTNAME=localhost

C:\Users\sandifer>SET ORACLE_UNQNAME=orcl

C:\Users\sandifer>emctl status dbconsole
OC4J Configuration issue. C:\app\sandifer\product\11.2.0\dbhome_1/oc4j/j2ee/OC4J_DBConsole_localhost_orcl not found.

I checked the above listed file path, and sure enough, OC4J_DBConsole_localhost_orcl is missing.

Would deeply appreciate it if someone would point me in the right direction.

Thanks,

Rob

what exists instead?
DIR C:\app\sandifer\product\11.2.0\dbhome_1/oc4j/j2ee/OC4J*

>OC4J_DBConsole_SANDIFER1.americas.hpqcorp.net_orcl
above indicates that once upon a time the system had a hostname of "SANDIFER1.americas.hpqcorp.net" before it was re-christened "localhost".

you must re-create EM's repository before EM will start for you.

Thank you...

So now my task becomes recreating the repository... It looks as though I will be researching how to do that and come up on the repository
learning curve...

After the repository has been recreated...are there any other steps that I need to perform...or will I then be able to bring up OEM? Thanks!

Regards,

RobS

Hi, Rob - you are doing OK for a beginner! And you have hit one of the most common issues: dbcontrol does not anything that hints of a hostname change. Try this:

emca -deconfig dbcontrol db -repos drop
emca -config dbcontrol db -repos create

And for the full sntax of the utility,

emca -h

Good luck. You'll need it.

Hi Rob, the listener must also be started before running EMCA utility.check the listener also, then only creating Enterprise Manager will be correct.

Greetings To All Of You Again,

I apologize for taking so long to get back; I got too busy with my Oracle learning classes and so had to temporarily pause this project of getting
EM to work - but I am back and would very much like to continue this discussion so that I can get this thing up and working properly!

John,

I followed your instructions to rebuild the em; and during the course of doing so, I received the following message:

"SEVERE: Listener is not up or database service is not registered with it. Start the Listener and register database service and run EM C
onfiguration Assistant again ."

I checked the status of the listener and it is running; so do I take this to mean that the database service is not registered with the listener...and if so, is there a proper way to do this? Thanks again!

Regards,

Rob
