OC4J Configuration issue...

First you should check database/instance configure for DATABASE CONTROL


If a hostname_sid directory does not exist in the Oracle Database 10g home directory, then the Oracle Enterprise Manager 10g Database Control Console was not configured for the database instance.




E:\>set oracle_sid=db01

E:\>emctl getemhome
Oracle Enterprise Manager 10g Database Control Release 10.1.0.2.0
Copyright (c) 1996, 2004 Oracle Corporation. All rights reserved.
EMHOME=C:\oracle\product\10.1.0\Db_1/taj.domainname.local_db01

If you get above output mean DATABASE configure FOR DB CONTROL otherwise DATABASE is not configure for DB CONTROL and you will see message like "EM Configuration issue".

We can configure DATABASE/INSTANCE for DB CONTROL through TWO WAY
1.DBCA
2.EMCA

DBCA
E:\>set oracle_sid=sh

E:\>emctl status dbconsole
OC4J Configuration issue. C:\oracle\product\10.1.0\Db_1/oc4j/j2ee/OC4J_DBConsole
_taj.domainname.local_sh not found.

E:\>dbca
Note : dbca ---> Configure Database option ---> Select DB and give PWD ---> Check Mark on Configure database with enterprise manager. ---> Finish
E:\>set oracle_sid=sh

Note : In 10.1.0.2.0 RepManager is not working properly so that we are not able to use below command.


emca -config dbcontrol db -repos recreate

If is working in 10.1.0.3.0
for you have to manully drop repository and create again.

Hi, Taj:

do you need to shutdown db to put it into a restricted mode to drop the repositary and user?

thanks

M.S.Taj said...

Hi,
Yes You need to shutdown your database.
like
[code]
shutdown immediate;
SQL> STARTUP RESTRICT;
After drop repository. again disable restricted session.

SQL>ALTER SYSTEM DISABLE RESTRICTED SESSION;


Hope this helps
Taj

Hi Taj,

Just like to say thank you for your tips i was able to run the EM for Oracle 10g after changing the hostname.

Thanks again!

Hi,

You are Welcome !!!

Hi Taj,

I am not a technical person but I have a virtual machine too on my laptop along with Oracle 10G. As soon as I start the virtual machine with Linux, the EM home changes and points to the linux host name. How do I run both of them simultaneously.

Pankaj

M.S.Taj said...

Hi,
Without Virtual Machine are you able to access OEM.

Dear Taj;
I have installed Oracle 10g on Window XP platform on my standalone machine and everything seemed fine during installation. I am able to run the commands from command prompt and SQL prompt. But after loggin in under EM, I am unable to proceed further.
While logging the EM does not throw any error message as wrong user or password, but it does not proceed to next page too.
From Command prompt following reading shows:-
emctl status agent shows Agent is running and ready.
emctl status dbconsole shows Oracle 10g EM is running.
NOW HOW TO SUCCESSFULLY LOG THROUGH EM... CAN YOU HELP ME PLEASE.

Regards-
rsp.

Hi, What does 2 SIDs: db01 and sh represent?
-Vincent

M.S.Taj said...

Hi,
"DB01","SH" is Database Name.
I have Two Database.

"DB01" is configure for DATABASE CONTROL.

"E:\>set oracle_sid=db01

E:\>emctl getemhome
Oracle Enterprise Manager 10g Database Control Release 10.1.0.2.0
Copyright (c) 1996, 2004 Oracle Corporation. All rights reserved.
EMHOME=C:\oracle\product\10.1.0\Db_1/alwarid-taj.fakhruddin.local_db01"



"SH" is not configure for DATABASE CONTROL


E:\>set oracle_sid=sh

E:\>emctl status dbconsole
OC4J Configuration issue. C:\oracle\product\10.1.0\Db_1/oc4j/j2ee/OC4J_DBConsole
_alwarid-taj.fakhruddin.local_sh not found.


For just example i used TWO DATABASE.

Taj

Taj, I am unable to restart dbconsole on an Oracle Database 10.2.0.1.0 instance. OEM was running successfully prior to performing an RMAN backup. After the backup I was unable to start agent or dbconsole. Below are some logs, trc file outputs. The os is Linux AS Release 4.

Prior to this I was unable to backup DB via OEM I had to use RMAN. The database is up but I am unable to access it via OEM and I and unable to start agents, dbconsole, etc. Additionally this instance houses HTML DB which was installed via the companion disk. Any insight would most appreciated.

Hi taj, I just installed Oracle 10G OIM and during the database creation there was an error regarding the repository and it tells me to run later the emca utility. However when I tried to use the emca and has set all the parameters like port, sid, etc. there was this error that the repository is already existing. My problem is that I cannot start my dbconsole and whenever i tried it it takes too long and will end up to failed.
What should I do in this case? should I drop the repository? and recreate again since reconfiguration is not able to work? please advise thanks!

Restart is not needed.

Mohammed Taj said...

...Restart is not needed....
Which services your talking about?
If you talking about DBCONSOLE services then it is needed to stop before drop otherwise you will get error message.

Greetings! I know this is kinda off topic
nevertheless I'd figured I'd ask. Would you be interested in
exchanging links or maybe guest writing a blog post or
vice-versa? My website goes over a lot of the
same subjects as yours and I think we could greatly benefit
from
each other. If you are interested feel free to
shoot me an email. I look forward to hearing from you! Fantastic blog by the way!
