Creating a Duplicate database from Active Database ( Without RMAN backup) on Same Server

This example below demonstrates on how to create a duplicate database on same server.

Pre-Requisites:
1) Create tns entry for auxiliary database ( I created for both target and auxiliary)
2) Create a password file for auxiliary (SYS password should be same for both target and auxiliary).
     If it's different, It failed.
3) Create a pfile for auxiliary instance and create necessary directory structure.

Sample Pfile:

db_name=dupdb
memory_target=1G
audit_file_dest=/u01/app/oracle/admin/dupdb/adump
audit_trail='db'
db_block_size=8192
db_domain=""
diagnostic_dest=/u01/app/oracle
dispatchers='(PROTOCOL=TCP)(SERVICE=ORA11XDB)'
open_cursors=300
undo_tablespace='UNDOTBS1'
control_files=/u02/oradata/dupdb/control01.ctl
compatible='11.1.0'
log_archive_dest='/u02/oradata/dupdb/archive/'
remote_login_passwordfile=exclusive
db_create_file_dest='/u02/oradata/dupdb' --> This is important to create datafiles.





Start the auxiliart instance into nomount mode
