K.,

Please check your TNSNAMES.ora file under your ORACLE_HOME/NETWORK/ADMIN directory. Review the connect string entry for the database you are trying to connect to - especially the host name/IP address of the machine where the database is. My guess is that this entry is incorrect.

hope this helps.

Hi,

I am not able to connect from my oracle client to an oracle db server (NT)

When i try to configure and test for the ora service(from my work station) it says "Connecting...ORA-12545: Connect failed because target host or object does not exist The test did not succeed.(this particular ora instance is not connectable from any workstation) "

Thanks in Advance

K.
