Database cloning using hot backup (if directory structure is different)

Below steps helps you in performing database cloning using hot backup
Assumptions:
1. directory structure is different in both source and target servers
2. Oracle version : 10.2.0.4
3. OS version : Linux 5
4. target database name is same as source database name

step 1 :  Take the hot backup of source database
sql> alter database begin backup;
$ copy datafiles to backup location
sql> alter database end backup;

step 2 : Take controlfile trace and pfile or spfile (that was using by the source database)

step 3 : Install Oracle software on another machine (choose “Install only” option in OUI). Don’t create any database

step 4 : Copy all the files (including trace file and pfile or spfile) from source server to target server either using FTP or rcp
Note: Not necessary in copying control files and redologfiles

step 5 : Place pfile or spfile in “dbs” directory on target

step 6 : Copy the remaining files to their respective locations (If any directories are missing, do create them)

step 7 : Connect as sysdba and Startup the database in nomount stage

step 8 : Edit the trace file (that was copied) and generate a create controlfile script from it. Modify the script and specify the new locations of  the files.

step 9 : Execute the controlfile script which will create controlfiles in the location specified in CONTROL_FILES parameter. Once control files are created, database will be forwarded to MOUNT state.
sql> @create_controlfile.sql

step 10 : Finally, Open the database with resetlogs option
sql> alter database open resetlogs;
