Question

problems with OracleDBConsole

Asked by: AlainD

Hi,

(Win Server 2003)
(Oracle 11g)

I need help troubleshooting a problem I have when re-starting the OracleDBConsole
in order to use the OEM again.

It has worked for the past week. then it started to behave erratically, like not displaying the "performance" page entirely. Then I could no longer connect.
Now i can't even get the logon page.

I read alot of PAQs and found out about the windows service OracleDBConsole,
which I tried to re-start unsucessfully. now it is "stopped".

The error I get in the Windows Event Viewer log is:

The OracleDBConsole***** service terminated with service-specific error 1 (0x1).

I tried using
emctl status dbconsole
at the command prompt but I get:

Environment variable ORACLE_SID is not defined. Please define it.

BUT..

select name from v$database
gives me the correct ORACLE_SID.

So the database is up and fine, I can log on using sqlplus, many people are using too,
I even tried our APEX installation and it works.

Any help will be appreciated.

Thanks,

initially it looks like you have created another instance which has rewritten your ORACLE_SID value in the registry.
please go to regedit and check that you have the right values under Oracle entry.
let me know!

 

by: it-rexPosted on 2009-09-28 at 15:59:42ID: 25444355

also have you done any recent upgrades

 

by: it-rexPosted on 2009-09-28 at 16:04:22ID: 25444382

also as per metalink
Doc ID:  752764.1
for The OracleDBConsole<SID> service terminated with service-specific error 1 (0x1).
do as follows:
1. Stop the database control
2. Please check if there is any process running with emagent, if so, kill/end the process.
3. Delete the following files
<ORACLE_HOME>/hostname_SID/emctl.pid
<ORACLE_HOME>/hostname_SID/emctl.pid_agent

4. Now start the DBConsole from the services panel or by using the command "net start OracleDBConsole<SID>"

This will start the service without any issues.

Registry: all entries are accurate under ORACLE>>SYSMAN>>OracleDBConsoleSID

No upgrades done either.

So as suggested I tried this:

I made sure the OracleDBConsole was stopped.
Checked if any process running: none.
Deleted file emctl.pid
Re-started the OracleDBConsole via the net command.

I got a progress bar for 15 minutes that ended with this:

------------------------------------------------

M:\>net start oracledbconsole******
The OracleDBConsole**** service is starting....................................
................................................................................
................................................................................
................................................................................
................................................................................
......................
The OracleDBConsole**** service could not be started.

A service specific error occurred: 1.

More help is available by typing NET HELPMSG 3547.

M:\>net helpmsg 3547

A service specific error occurred: ***.

EXPLANATION

A service-specific error occurred.

ACTION

Refer to the Help or documentation for that service to determine the problem.

---------------------------------------------------

While the service was trying to start,
I queried the v$session view and saw 2 new sessions with program = 'emagent.exe'

When the process failed to start, those two sesions dissapeared.

what do you currently have under <ORACLE_HOME>/hostname_SID?

 

by: it-rexPosted on 2009-09-28 at 17:51:36ID: 25445087

 

by: AlainDPosted on 2009-09-28 at 17:52:30ID: 25445096

a folder named "SYSMAN"
and a file named emctl.pid

 

by: AlainDPosted on 2009-09-28 at 18:02:34ID: 25445160


So i'll try this as your link suggests:

"
delete files under:
\sysman\emd\state
\sysman\emd\upload
and
\sysman\log

After that,
emctl start agent "

(or emctl start oracledbconsole ?)


 

by: AlainDPosted on 2009-09-28 at 18:51:58ID: 25445375

...and it failed.

I'm thinking about re-creating the whole EM, maybe using emca?
not sure what I'm getting into..

 

by: AlainDPosted on 2009-09-30 at 05:54:34ID: 25458243

Ok this is what I did:

emca -deconfig dbcontrol db -repos -drop

then I got errors saying a file could not be deleted
(datasources.jar)

tried deleting the file manually: some process had a handle on it so I could not.
re-booted the server

emca -deconfig dbcontrol db -repos -drop,
error message saying could not dropped user DBMS?

decided to try to build it instead:
emca -config dbcontrol db -repos -create

and that worked.

the perfomance page is still slow and I got certificate errors whenever I access the page but that'll be something to fix on another day.

Thanks for your help it got me started figuring this out,
