Thanks.Hi
Follow the below steps
1.) create the password file
2.) If u have the pfile of the target database ,then edit the pfile contents like location and name to new location and names.
3.) Now takes startup the database to nomount statge
4.) Now create the controlfile . Check the below link for creating the controlfile
http://neeraj-dba.blogspot.in/2011/04/create-control-file-manually-when-and.html
5.) After creating the control mount the database .
6.) Once the copied the datafiles as the location specified in the controlfile
7.) Finally open the database .

Create new db from RAC cold backup

Hi Team
i need to copy cold database from one server to another server . and build an new rac database out of that cold backup .. i have done it for singel node instance . but do you know if i have to do something special for RAC instance .. or simply below mention steps are enough to build RAC database out of cold backup
oracle version is 10.2.0.1
1. install software and clusterware on new set of machine
2. copy cold backup on that set of machine
3.copy spfile and controlfile
4.open the database up with controlfile,spfile and dbf files
now i am not sure on one thing if i have to do something special for RAC DB or its like single instance.
please let me know if this is not clear or you need more info on that

Clone database from server to PC

Hi all,
I am having the difficulty after clone the database from a hot backup from server. Both server & PC running at W2k OS and Oracle 8.1.7. Below are the steps what i am doing.
1)Take a hot backup from the server.
2)Create a folder \oracle\oradata\CLONE. Stored all the datafiles there.
3)Copy the init.ora from the server and paste to \oracle\admin\CLONE\pfile. Amended all the location, instance name, db name, etc.
4)log in to server and run the command, ALTER SYSTEM BACKUP CONTROLFILE TO TRACE RESETLOGS.
5)Copy the trace file and amend to the create control file script. Alter the script like
STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE "CLONE" RESETLOGS ARCHIVELOG
MAXLOGFILES 5
MAXLOGMEMBERS 3
6)Also created the service using the command ORADIM.
7)Under OS command line, SET ORACLE_SID=CLONE and then log in the SQL*PLUS. Once i executed the create control script. I hv encounter error like ORA-27100: shared memory realm already exists.
Could anyone tell me why this error occurs and how to solve the problem.
TQ,
Alfred

Your got this error because you try to create a new control files on an open instance.
You need to shutdown the instance ( SQL>shutdown immediate ) and connect back to the database using the nolog flag, then do connect to the sysadm, this will start the backgroup process. just them you will be able to initiate your command.
SQL> shutdown immediate
c:\>sqlplus /nolog
SQL>connect /as sysdba

Create a database from 8i RMAN backup

Hi,
I am in need to recover some historic data from a historic database's RMAN backup.
The situation is ... I have one old RMAN backup of a 8i database which includes datafiles, archivellog files and control files. Init.ora file is also available.
I have installed the 8i software in a host and created the oracle service through ORADIM and pwd file through ORAPWD utility. Then copied the init.ora file under 'C:\Oracle\ADMIN\ORCL\PFILE' and the RMAN backup files under 'C:\Oracle\Ora81\DATABASE' folder.
Now I can start the instance with the init.ora file but can not mount as control files are not there. when I try to restore the control files through RMAN as...
RMAN> run
2> {
3> restore controlfile;
4> }
RMAN-03022: compiling command: restore
RMAN-03022: compiling command: IRESTORE

RMAN-06172: not connected to recovery catalog database
RMAN>
Now without the catalog database how can I restore the control files and the database from the RMAN backup?
I think the old RMAN metadata was stored in catalog database.
Any suggestion please?
regards

Sorry I wrongly said that I do not have the DBID, I have DBID but I have controlfile backup as RMAN backupset, not in Binary. So even if I set DBID, RMAN asks for the catalog database, which is not available.

Problem to copy database from the hot backup

Oracle9i Enterprise Edition Release 9.2.0.4.0
SunOS 5.8
Hi all,
I wrote the UNIX script to copy the production Oracle 9i database from the hot backup to the Oracle 9i development database. I already did it manually without any problems using Metalink document Note:18070.1
The script stops after the command
recover database until cancel using backup controlfile ,
because I have to apply all archived logs manually.
How is it possible to get rid of this problem and automatically apply archived logs?
Thank you in advance for your help.
Alex
P.S. We are not authorized to use RMAN.

P.S. We are not authorized to use RMAN. We dont get your point?
Who stops you using RMAN?
How did you take the hot backup then?
There are couple of good notes on metalink, and below is one of them,

RAC to RAC CLONE FROM RMAN Cold Backup

Hi All,
I need your kind assistance in Cloning my Oracle RAC 11.2.0.2 Environment to remote host. Following is Disk layout
DGVOT (ASM Disk group holding OCR and Voting Disk)
DGDATA (ASM Disk Group Holding Data FIles)
DGFRA (ASM Disk Group Holding Fast Recovery FIles)
Remote Host is on different location so cannot use RMAN duplicate with auxiliary channel.
Have luxury of downtime so I want to take RMAN Consistent( Cold Backup)
SAME Disk layout is available to remote hosts.
11.2.0.2 CLusterware (GI) Plus the oracle binaries are already installed.
Can any body tell me the steps to
1) How to take cold backup to disk so that I can tar and copy to remote host
2) clone the database on remote host
3) How i will add the database listener and other resources of this databasee to clusterware.
actually this is my first RAC clone so i am not much aware of detail steps.
I have gone though many metalink notes but no one is matching with my requirements. your expert advice will help me a lot
Regards,

Hi
1) How to take cold backup to disk so that I can tar and copy to remote host.
Use Rman for cold backupIn mount stage execute
RMAN>backup database plus archivelog format '<disk_path>/dbp%U';
RMAN> backup current controlfile format '<disk_path>/ctl%U';
Copy thse backup sets to remote host
2) clone the database on remote host
Create Similar ASM Disk groups as on source
create pfile/spifile, startup instance in nomount mode
catalog backup set
RMAN> catalog start with '<backup_set location>';
Restore controlfile
RMAN>restore controlfile;
RMAN> restore database;
RMAN> recover database;
On successfull recovery
RMAN>sql 'alter database open';
3) How i will add the database listener and other resources of this databasee to clusterware.
User srvctl to add resources
Usage: srvctl <command> <object> [<options>]
commands: enable|disable|start|stop|relocate|status|add|remove|modify|getenv|setenv|unsetenv|config|convert|upgrade
objects: database|instance|service|nodeapps|vip|network|asm|diskgroup|listener|srvpool|server|scan|scan_listener|oc4j|home|filesystem|gns|cvu
For detailed help on each command and object and its options use:
srvctl <command> -h or
srvctl <command> <object> -h

How to clone database from backup without access to original DB

I want to create a new database from existing backup files and rolling forward some of the archivelogs (preferably with a new name and with different directory layout).
How can I achieve the task on a separate test server (without access to the original database)? I found a lot of sources ( e.g. http://www.oracle-base.com/articles/11g/DuplicateDatabaseUsingRMAN_11gR2.php ) but all with connection to original DB (e.g. entries in tnsanmes.ora)
Backup runs a simple
BACKUP DATABASE PLUS ARCHIVELOG;
DB Version is 11.2.0.2 on Linux.

Many thanks to your help. Finally I was able to restore the DB. The steps I used (similiarly also mentioned in some of the links above).
1.) Copy backup (backupset, autobackup, archivelog) to the new server into directories
/export/restore/autobackup/2012_03_01
/export/restore/autobackup/2012_03_02
/export/restore/archivelog/2012_03_01
/export/restore/backupset/2012_03_01
2.) create pfile initDBREST.ora
DB_NAME=DBREST
3.) Mount DB
ORACLE_SID=DBREST; export ORACLE_SID
sqlplus / as sysdba
STARTUP NOMOUNT;
4.) Connect to auxiliary DB
ORACLE_SID=DBREST; export ORACLE_SID
rman AUXILIARY /
5.) Create directories for new DB for datafiles in e.g. /export/oradata/DBREST/
6.) Duplicate DB and reset parameter if necessary (e.g. memory_max as test server is lower on RAM)
DUPLICATE DATABASE TO DBREST
until time "to_date('02.03.2012 15:00:00','DD.MM.YYYY hh24:mi:ss')"
DB_FILE_NAME_CONVERT '/export/fs1/oradata/oldDB/','/export/oradata/DBREST/', '/export/fs2/oradata/oldDB/','/export/oradata/DBREST/'
SPFILE
SET MEMORY_TARGET '2G'
SET MEMORY_MAX_TARGET '2G'
SET db_recovery_file_dest '/export/oradata/'
SET db_recovery_file_dest_size '100G'
BACKUP LOCATION '/export/restore'
NOFILENAMECHECK;
7.) create temporary tablespace

How to recovery the database from a complete backup

I have a 10.2.0.3 database with archive log enabled.
I do a cold backup of database every Sunday night.
I shutdown the database, copy all the database files, control files and redo logs to a backup disk.
Then the database started and running again.
I am trying to test my backup and make sure I can recovery the database to the most current stage using the Sunday backup and the archive logs.
for example: use the backup from 4/01/2012, recover the database to today 4/04/2012 9:00am.
What's the steps of doing this?
I tried to copy all the Sunday backup files to the correct location, start the database, the database is started successfully. However, I don't know how to apply the logs from since the Sunday backup upto now.
Thanks a lot!

hi,
rman is your friend to do backups, restores and recovers of database.
to do a full recover of database, for example to do a test on your current test database (no in crash):
rman time:
startup nomount;
restore controlfile;
alter database mount;
sql now
select archivelog_change#-1 from v$database;
then go back to rman and do the following :
RMAN> run{
2> set until scn xxxxxx;
3> restore database;
4> recover database;
5> alter database open resetlogs;
6> }
**where xxxxx is the result of your sql query

--edit:
forgot to told that You will need to set your ORACLE_HOME and ORACLE_SID env variables

Please let know the setps for creating new databaseIf it is in archivelog mode you can use duplicate to refresh database DEMO from TEST..
or after cold backup, go to mount ,
create trace file of controlfile becuase you are chaning database name
recreate the controlfile

Database cloning using cold backup

Hello Guys,
I am doing cloning of a database from cold backup for testing, actully one datafile has been croupted, so my issue is that, can i exclude tht datafile from controlfile when creating the controlfile and is that poosible that controlfile will created sucessfully and database will open sucessfully.
Please reply.
Thanks

@asif, @ckpt
With humble, how all you know that corrupted datafile is not belonging to system and undo tablespace? If this case, then do you think we can restore that corrupted cold-backup ? Sorry, but this is not the way to just start providing help without asking OP :
1.Current Oracle Version ?
2.Where he want to restore i.e. restoring platform info Oracle version OS ?
3.After cold backup how he came to know that one datafile is corrupted ?
4.When and how datafile became corrupted ?
5.How he taken cold backup ? Was db running fine just before shut immediate for cold backing ?
6.What he has done so far to restore the cold backup ?
7.What error he is getting right now ?
Here problem is corrupted datafile. So, first let come problem clear from OP, ask all missing question in one go, and then start helping is the right way... (my personal opinion, may be wrong!).

Creating a standbay database from an rman backup

hi,
I have a situation that a standby database has a large gap in archive log files, the primary server does not now have those files. I understand that you can create a standby from an rman backup of the primary but all reading I have done shows thatn you have to have a recovery catalog to carry this out. The system I am on does not have such a catalog so is there any other way to do this?
regards
Alan

Requirement 'You must have a recovery catalog in a standby requirement' is a little bit misleading. In fact you can do what you want : creating a standby from RMAN backups without having a recovery catalog. 'Duplicate target database for standby' does not require a connection to a recovery catalog.
You need mandatorily a recovery catalog, when you plan to take backups from the standby later on in order to free the primary from this task. The reason for that is it's not possible to transfer backup records from the standby controlfiles to the primary ones directly. After a backup on the standby you resync the catalog with the standby controlfile. Then you connect to the catalog and the primary,resync again and have actual backup informations in the primary controlfiles. When there's a media recovery problem, you easily can restore/recover the primary.

Is it possible to restore database from a full backup without controlfile?

Hi,
I have done a full backup for the database oracle 11g using:
run{
allocate channel c1 type disk;
set limit channel c1 kbytes 102400;
sql 'alter system archive log current';
backup full tag 'dbfull' format 'd:\dbbackup\f_%d_%u_%s_%p_%t' database include current controlfile;
backup archivelog all delete input format 'd:\dbbackup\al__%d_%u_%s_%p_%t';
release channel c1;
but, I deleted all the datafiles include all control files.
Is it possible to restore the database?
Is there a way to restore the control file from the backup files?

Thanks Werner!
I finally find the correct backuppiece for the controlfile.

Rollback from a cold backup

Hi,
i've done a cold backup now and i've some old archivelog.
I need to do a restore poin in time back to the past using my cold backup and
the last 2 archivelog.
How can i do?

Hi,
I thinked over and I say it might possible provided, all archive logs are available.
Restore the cold backup to New Server
Mount the DB
start recovery using backupcontrolf file clause until some time in back.
Perhaps, with out happening or inconsistent - usually recovery might not happend, but still when you go for "using backup control file" - recovery applies / starts based on the control file status and Reset logs might be needed. So, in that case go back and specify time.
I doubt it, whether it works or not... I need to have break ..!! Test on some separate testing server.

Create a database from 32bit rman backup with NEW name on a 64bit system

Hello,
i'm more programmer than database admin but i need to set up a 10gR2 apex development server based on our productive instance in a short time.
For that i want to use a rman backup of the productive machine (SLES 10 32bit, DB10GR2+ASM, APEX 3.1).
Because of the less time i got, i want to use an existing machine (SLES 11 64bit, DB10GR2+ASM) as destination.
On this machine i want to create a new instance from the backup i took. I Already read note 881395.1 but i'm quite unsure about 2 things
a) It's VERY IMPORTANT that the development instance has another name than the productive instance.
When i follow 881395.1 and set the enviromental variable ORACLE_SID to another new name. Will this be all? Or will there be problems using another SID because of references in the controlfile or sth. like that?
b) It's VERY IMPORTANT that the datafiles aren't stored in the same path and with the same names as the productive instance. It is another server but there is already a copy of the database (our dba tried to set up a standby solution on this machine) and i don't want to bother this!
How can i rename the datafiles before restoring the backup from scatch?
I found this: set newname for datafile 1 to '<filesystem based filename>';
Will this help? Do i need to rename every single file? Or is it possible to set a path in which all datafiles will be restored?
c) What about the 32bit to 64 bit thing? Will this work? Or do i need to convert the database? How? RMAN Convert?
Or could RMAN convert anyhow used to realize the whole thing?
Thank you very much for your support!
Regards
Daniel

Thank you very much for your support!

Restoring and Recovering from RMAN cold backup

DB Version: 11gR2
os : Solaris
Before dropping a DB we had taken an RMAN backup of the DB using
RMAN> backup database;We hadn't set a FORMAT (like db_%d_S_%s_P_%p_T_%t) for this DB , so the backups went to ORACLE_HOME/dbs directory. The 2 backup files are
/u02/app/oracle/11.2/db/dbs/01mo9fms_1_1
/u02/app/oracle/11.2/db/dbs/02mo9fnc_1_1 -- spfile and control fileNow we need to recreate this DB on a new server.
In the new server, we've placed the backup files in /u04/backup/rmanbkp .
Since We hadn't set a FORMAT parameter for the original DB which we have dropped what format i will give during restore?
Will RMAN automatically recognize the FORMAT of the backup piece and restore ?
RMAN> run
allocate channel c1 device type disk format 'i_dont_know_the_format';
allocate channel c2 device type disk format 'i_dont_know_the_format';
restore controlfile;
restore database;
}This the SHOW ALL output from the DB we have dropped .
RMAN> show all;
RMAN configuration parameters for database with db_unique_name BRCFTST are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u02/app/oracle/11.2/db/snapcf_brcftst.f'; # defaultAs you can see we hadn't set the format explicitly , ie. the line
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT is missing

Hi,
Before dropping a DB we had taken an RMAN backup.I hope you were in mount mode.
Will RMAN automatically recognize the FORMAT of the backup piece and restore ?No it won't.
First you have to restore a controlfile in nomount mode with:
restore controlfile from '/u04/backup/rmanbkp /02mo9fnc_1_1';
and do alter database mount.
Than you have to run "catalog start with '/u04/backup/rmanbkp'; " so the instance now knows where to find the pieces.
Now you can run a restore database command.
Than open the database with resetlogs.
