Hi all,
I am trying to upgrade database from 10.2.0.1.0 to 10.2.0.5.0,I have 5 database running in the server so i dont want to shutdown all the database at once ,so i decided to do for each database with the following steps and give a try ,when i try to connect a database for upgrade ,it throws error(+ORA-12557: TNS:protocol adapter not loadable+),please help me to resolve and correct me if i am wrong .
1.Installed oracle 10.2.0.1.0 in new location on same server.
2. Apply patches and upgrade the oracle to 10.2.0.5.0 in new location on same server
3. set ORCLE_HOME=<newly installed home path>
