TNS Listener issue

[mayura.ch]

I have two databases on one machine. I can login to only one db at a time. If I try to connect other db it gives me the error:

TNS listener currently does not know service requested in connect descriptor.

Even if I set the oracle_sid "ORADB", it get connected to "ORADEV". And if I specify the Connect identifiet it gives me TNS error.

Kindly assist.

Regards,
Mayura

How many listeners? one per instance?

Either way, issue is most likely related to an issue on tnsnames.ora file.

For future reference - for better/faster help copy/paste session log as well as printout of related files.

The Db name mentioned above were just examples. The actual db names are in tns file below. The details as as below:

check out why the status of the above instance is blocked.

Thanks,

[mayura.ch]

But orad2 is on different server and gisdev,giszgg are on same server. And I am trying to keep gisdev and giszgg UP at the same time..

Mean while I will check the reason being orad2 blocked.

Thanks...

[mayura.ch]

Now I do not have the status Blocked.

Can anyone let me know why I am not able to connect both the servers at a time?

The issue was I have created giszgg cloned db from orad2. GISZGG and GISDEV are on same server. gisdev was up and running when I did clone and now all the trace files and alert log is getting created by gisdev suffix. Help me out to get solution on this so that GISZGG and GISDEV can run independantly?

[gandolf989]

Do a tnsping to both databases and post the results. Verify that the entries in the tnsnames.ora file are connect and point to different databases. Check your listener.ora file, verify the sid names, ports and server names. If everything looks correct try renaming the sqlnet.ora file and then connecting to both databases.

[mayura.ch]

I can do tnsping to both the dbs

See the below error. That's very strange:

and the listener.ora is:

according to me you cannot have two listeners listening to same port at a time,so i would suggest to separate out the listener ,create a new listener.ora assign new port(say 1529) set local_listener parameter.You should be all set

[pobby69]

In our listener.ora file, in the SID_LIST_LISTENER section we have multiple databases specified in the SID_LIST. For example:

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /apps/oracle/10gR2)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = db1.domain.co.uk)
(ORACLE_HOME = /apps/oracle/10gR2)
(SID_NAME = db1)
)
(SID_DESC =
(GLOBAL_DBNAME = db2.domain.co.k)
(ORACLE_HOME = /apps/oracle/10gR2)
(SID_NAME = db2)
)
)

This does mean that we only have one listener for all our DBs, if you want one listener per DB then I guess you would need similiar to above but with something like SID_LIST_LISTENER1 and then SID_LIST_LISTENER2. Each with their single SID_LIST and SID_DESC section.

Is that of any help?

With the tnsnames.ora file we have our SIDs listed, all with the same port.
