ORA-12560: TNS: protocol adapter error

[Nikee]

Hello,

The system is generating the error “ORA-12560: TNS: protocol adapter error” when we tried to connect to the oracle database(8.1.7) using SVRMGRL.
Where as we are able to connect to the database using sqlplus system/manager@bob

Please help me how to resolve this issue.


Thanks,
Nikee

Hi,
Is it an NT or Unix box ? Check the value of ORACLE_SID - this is a O/S variable & set that to U'r Oracle SID.

Hello Ganesh,

Thanks for the reply.
We are running on WINDOWS 2000 Service pack 2. I have already set the environment variable ORACLE_SID=BOB

Hello Ganesh,

Here are some addtional information.

I am able to start the Listener service from windows servives, where as I am unable to start the Listener from the command prompt.
i.e. lsnrctl start

At this point system is displaying the following information:
Starting tnslsnr: please wait..

Thanks,

Since you are able to connect to the database, through sqlplus that shows that the listeners are up and functional.

To connect to the server manager fist you would have to

set ORACLE_SID=bob
svrmgrl##
svrmgr> connect internal


I would suggest that you get accoustom to that of using sqlplus to do the administration as svrmgrl had been discontinued as of 9i.

set your ORACLE_SID
sqlplus "/ as sysdba"


Good luck.

Hello SAM,

Thanks for the suggestion.

Here I am just investigating the bug source. I am also able to connect to the database using the SVRMGRL but not the first time.

D:\>svrmgrl

Oracle Server Manager Release 3.1.7.0.0 - Production

Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved.

ORA-12560: TNSrotocol adapter error
SVRMGR> connect internal@bob
Connected.
SVRMGR>

I am just wondering what excatly the error is.

Thanks.

That is because you have not set your ORACLE_SID the environment variable.

D:\> set ORACLE_SID=bob (check the set command syntax)

Hello Sam,

The answer is 'NO, it is not working'.

I have opened this message after testing all kinds of possibility options.


Thanks,
