I need clear step by step instructions on how to clone a oracle 10.2 database instance from one linux DB server to another. Basically between $ORACLE_HOMEs. I'd like to use it just at a file level without using RMAN or OEM, especially since this is between different oracle homes.

If you would like to try Oracle"s migration utility, we can provide the source url if needed.

vyomu,

If you have a target server with the same version of Oracle Database already running on it, all you need to do is shut down the database on the source system and copy it over. Once it is there, make sure that you have created the same OS owner and group accounts, set the database files as that owner/group, set your correct ORACLE_HOME and ORACLE_SID environment variables, and you should be able to start it up.

You just have to be cautious about checking the listner and tnsnames files to ensure that the IP addresses or hostnames are correctly set to the new values.

You don't need to use a migration utility unless you are upgrading or trying to perform some type of change to the database such as changing character sets.

Problem could be the 2 different homes with a plain c&p.

My suggestion deals with it.
