Oracle 10.2 database not responding

Hi,

I have a 10.2 oracle database. The startup of this database works fine. Starting the listener works fine too (no errors).

When i run a Sqlplus session in local way (setting the ORACLE_SID env var before launching sqlplus) it works fine too.

But when i try "sqlplus system/password@SID" the server doesn't respond :
nothing ... no error codes.
When i try TOAD, it's the same thing ... no response
When i try Oracle Enterprise Manager the doesn't respond too.

Notice that Oracle is not "installed" on this dev machine but "copied-pasted" from another where everything works fine. I also export the registry entries for oracle from the working machine to the dev machine, but it does'nt work anymore.

any suggestions ?

The problem is that i can't disable the firewall on the machine because of windows domain restriction ... i just can add exceptions ... do you know wich programs i must add to the exception ? I addes oracle.exe, tnslsnr.exe, sqlplus.exe, i also authorized the 1521 port wich is the port of my database ...

You said you cut-n-pasted from another server. This is unusual for Windows, I only do this on UNIX platforms. You should really install properly before bringing a database over, due to registry requirements.

Also, consider backing up all .ora files in $ORACLE_HOME\network\admin and rerunning netca to configure the listener and tnsnames.

If you did not actually install Oracle, this may not work either. You have installed it incorrectly, and I can tell you, on Windows, the Oracle listener is very picky about configuration. Even on a proper install, to re-create a listener requires deleting the service, removing a registry entry, rebooting, then rerunning the listener config / netca.

thank's mrjoltcola ... But it now works properly.

I didn't install oracle only a copy/paste from our network.

The problem was that the listener seems to only cummunicate with a windows' service. So you must install your db as a service with the tool oradim (oradim -new -sid SID) and that's all.

I have also some scripts because the dev machine will host potentially 50 db instances ... so we must shutdown instances properly.

thank's to this forum ... ;)

>>the expert didn't find a solution for me ... saying no solution was available

I did not say that. I clearly said you should install properly. Please don't misquote me.


Yes, you ran oradim, this is what happens when you do the install normally or by running DBCA through the usual way. And as a side effect, it creates a listener for you. Note I said:

"Even on a proper install, to re-create a listener requires deleting the service, removing a registry entry, rebooting, then rerunning the listener config / netca."


Anyway thanks for the post back on your solution. I might have suggested you checking the services and rerunning oradim as well, but I don't agree with this method of installing Oracle, so I recommended the supported way.
