Rick, here is how I do it. Contact me if there are any questions.
Make a copy of 'prod' on LAWDB to 'test' on LAWDB from Cold Backup
Introduction
The 'prod' Oracle instance sometimes need to be replicated, on demand, for
testing and/or training purposes. The replication is done using a 'Cold'
backup copy of the 'prod' instance using either the backup directory
(/dbkup) or the ADSM backup. The procedure is very much the same for
creating either 'test' or 'train'. This section will assume creating a 'test
' database.
Procedure
? Take a cold backup of 'prod'
? Shutdown 'test' instance
The 'test' instance should be shutdown using 'immediate' option.
>ORACLE_SID=test
>export ORACLE_SID
>svrmgrl
SVRMGR> connect / as sysdba;
connected;
SVRMGR> select name from v$database;
NAME
---------
TEST
1 row selected.
SVRMGR> oradebug ipc
SVRMGR> shutdown immediate;
SVRMGR> exit;
? Copy the datafiles files from the cold backup
Delete ALL TEST database related files, i.e. *.dbf, *.ctl, *.log
Use the cold backup to copy the .dbf files to the "test" instance
mountpoints
? Re-create control files & redo logs for the "test" instance.
(See example belos)
Use the 'make control file' script
>ORACLE_SID=test
>export ORACLE_SID
>cd $HOME/test/admin
>svrmgrl
SVRMGR> connect / as sysdba
SVRMGR> @mkctrl
SVRMGR> select name from v$database;
Example of creating control files & redo logs:
STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE "lawtst5" RESETLOGS NOARCHIVELOG
MAXLOGFILES 32
MAXLOGMEMBERS 2
MAXDATAFILES 200
MAXINSTANCES 8
MAXLOGHISTORY 800
LOGFILE
GROUP 1 '/db/u05/oradata/lawtst5/redo01.log' SIZE 64M,
GROUP 2 '/db/u06/oradata/lawtst5/redo02.log' SIZE 64M,
GROUP 3 '/db/u07/oradata/lawtst5/redo03.log' SIZE 64M
DATAFILE
'/db/u05/oradata/lawtst5/system01.dbf',
.
.
.
. '/db/u04/oradata/lawtst5/index22.dbf',
'/db/u04/oradata/lawtst5/index23.dbf',
'/db/u04/oradata/lawtst5/index24.dbf'
;
ALTER DATABASE OPEN RESETLOGS;
ALTER DATABASE RENAME GLOBAL_NAME TO "LAWTST5.WORLD";
