Like I said in your other question, 99% of the time an ora-12170 is caused by a firewall issue.

Check your listener and tnssnames files for proper ip/host info.

Check if you can login using SQLPLUS using "sys/sys@oracle10 as sysdba".  If not fix the SQLNET/TNS issue and then proceed with RMAN backup.

"/" and using "@oracle10" do two different things.  One does a direct connect.  The other uses SQLNet.


sqlplus "/ as sysdba"  is not the same as: sqlplus "sys/sys@oracle10 as sysdba"

try: rman target /

Didn't we just go through this in your other question just an hour or so ago:  SET YOUR ORACLE_SID AND ORACLE_HOME FIRST!

About solving the 12170 error: First try turning off the Windows firewall.  and as in the other question: Check the IP address/host in your listener.ora and tnsnames.ora file.  Since you are running locally, set them to use the loopback adapter (I believe we've covered this in one of your older questions) and set the ip address to 127.0.0.1.

Hi,

As per the message you got, it seems that your database is not open currently. Inorder to connect to  a database remotely the instance has to be started.

First start the instance and then connect to the rman. Also if you'r connecting using Oracle Net then you need to mentioned the password that you have given in your password file.

Try this..

> set oracle_home=C:\oracle\product\10.2.0\db_1
> set oracle_sid=oracle10
> sqlplus / as sysdba
> startup

>exit

> rman target /

(or)

if connecting using remote authentication then mentioned the password whcih been mentioned in
the password file.


>rman target sys/password_mention_in_password_file@oracle

Thanks..
