Problem starting database. [message #310568]

First post, so hopefully i'm putting this in the right forum.

I'm pretty new to both Oracle and Redhat and recently installed Oracle 10g on my home machine. After the installation everything worked, and I could use the URL to login to Enterprise Manager. I'm currently working through getting everything to startup at boot. The problem I just ran into is a little odd though, after logging in, starting the listener, logging into sql, starting/mounting the database, i get nothing when i try to use the Enterprise Manager URL. It's not giving any sort of Invalid URL/Can't Connect error...it's just loading a blank screen. Any help would be greatly appreciated.

You need to start the dbconsole process:

emctl start dbconsole

I tried that, and I still seem to be having a problem. I'm sure i'm missing something obvious. Embarassed

All my status checks look ok:
------------------------------------------
emctl status dbconsole
TZ set to US/Eastern
Oracle Enterprise Manager 10g Database Control Release 10.1.0.2.0
Copyright (c) 1996, 2004 Oracle Corporation. All rights reserved.
http://localhost.localdomain:5500/em/console/aboutApplication
Oracle Enterprise Manager 10g is running.
------------------------------------------

------------------------------------------
lsnrctl status
Services Summary...
Service "PLSExtProc" has 1 instance(s).
Instance "PLSExtProc", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
------------------------------------------

But i'm still not getting anything other than a blank page. I was getting a message about "EM Daemon is not running" with the dbconsole status, but that's gone away.

thanks again for any help.

I did have it running, but the firewall was disabled. I've turned it off since, but i'm still having the same problem.

I did notice this when i run dbstart though:

I'm guessing that those errors and the "Database "orcl" warm started" message may be something worth investigating?

It's just a guess and sorry , it's not related to oracle .
Have you tried checking if it listed in "trusted" list of IE ?

I had the same problem with Windows 2003 and that was the reason .

Good Luck

DB console can start regardless of your listener status or database status. In addition, trying to register the database isn't going to do any good in your case.

Try to change your listener port to 1521 and stop/start your listener and then stop/start dbconsole again.

I just answer that his

Quote:

lsnrctl status

command. It is not showing any available service. Alter alter system register it will show the available service.

And I considered myself his Datbase control is ok after getting the message,

Not unless the OP has the appropriate database parameter set for the listener.

Sorry it's taken me so long to respond to everybody's suggestions...i was away for a few weeks.

I tried the alter system register command, but the lsnrctl status stayed the same.

I also tried switching my port to 1521. (As far as I know, the only places i need to change that are in listener.ora and tnsnames.ora, correct?) But unfortunately, i'm still having the same problem.
