“ORA-12545: Connect failed because target host or object does not exist” using / as sysdba July 5, 2011

Posted by sendtoshailesh in Uncategorized.

ORA-12545 is very common error and people use to get this quite frequently as soon as they have some mis-configuration in oracle client configuration files.

sometime back while working on a recovery issue I got this issue when I tried to connect db as “/ as sysdba” on the same host where db was running. the strange is I got this error……. this was haunting for me and I thought lot of option but nothing worked.

After couple of troubleshootings I came to know that we are missing $ORACLE_HOME/bin/oracle file. I asked unix to restore this file. database opened and now up and running.

Enjoy !!
