Duplicating a Database with RMAN

Hi,
When Duplicating the database using RMAN,
does it build the auxilary database from the existing rman backups of the target database
or
will it build direcly from the open / mount stage of the target dabase (where there is no concept of rman backups)
Please advice.
Thanks
Naveen.

That depends on the version- Before 11g, RMAN took a previous created backup to duplicate. In 11g, we introduced the new command
RMAN> duplicate target database *from active database* ;that does it "on the fly" without backup needed.

Trying to restore a database with RMAN in new server

Hello,
Database: Oracle 10gR2
O/S: Windows Server 2003
My RMAN backuppieces are stored in a network drive:
\\old_location\FULL
and
\\old_location\INC
I'm trying to restore a whole database with RMAN in another server from my FULL backup.
For that, I copy all backuppieces files
from: \\old_location\FULL
to new server: D:\new_location\
Also I created the relevant folder hierarchy under <ORACLE_BASE> directory, as follows:
a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>\admin' directory
b. Create <DATABASE_NAME> directory under '<ORACLE_BASE>\oradata' directory
c. pfile.ora and controlfile (CTL_MTDPROD_2308_20120401_1.CTL) are backup from original database and they are in D:\new_location\
d. I copied pfile.ora and controlfile to folder: C:\oracle\product\10.2.0\db_1\database\
I started creating an instance in new server from scratch:
C:\>oradim -new -sid MTDPROD -intpwd mtdprod
C:\> SET ORACLE_SID=MTDPROD
C:\> rman
RMAN> connect target sys
RMAN> SET DBID=21692876873
RMAN> STARTUP force nomount PFILE=C:\oracle\product\10.2.0\db_1\database\init_mtdprod.ora
RMAN> restore controlfile from 'C:\oracle\product\10.2.0\db_1\database\CTL_MTDPROD_2308_20120401_1.CTL';
RMAN> alter database mount;
#Since I want to read my backuppieces from D:\new_location and not from \\old_location\FULL then I catalog and restore like:
RMAN> catalog start with 'D:\new_location\';
RMAN> restore database;

Questions:
1. RMAN still reads from old_location. The only way to avoid that would be deleting all files from \\old_location\FULL ?
2. The message "failover to piece handle=D:\new_location\...." indicates that that file is not usefull? I just copy them from old_location to new_location... how can they get useless?
I suspect there is something in controlfile that redirects to \\old_location\FULL\ and doesn't let to read from D:\new_location\
Please, advice.

You may want to check the output of RESTORE DATABASE PREVIEW command, which will just report which backup files it uses without actually restoring thhe DB.

Problem creating physical Standby database with RMAN

Hi All
I am trying to learn oracle dataguard and as part of the process learning creating standby database.
Platform : Sun-Fire-V250 Sparc, Solaris 10
Database Version - Oracle 11R2
I am creating standby database on same server, so directory structure is different.
Following the instructions on Oracle site I managed to create a functional physical standby database. But I am not able to create standby database using RMAN. These are the steps that I followed-
1.Set up all necessary parameters on primary database as done while creating physical standby database manually, eg setting force logging, creating standby logs etc.
2.Edited parameter file on primary database as done while creating manual pysical standby database creation. Some of the changes done are-
On Primary Database:
*.FAL_CLIENT='orcl11020' #Primary database unique name
*.FAL_SERVER='stdby_11' #Standby database unique name
db_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020'
log_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11/redo_mem','/<dir>/oradata/orcl11020/redo_mem'
standby_file_management=auto
*.log_archive_config='DG_CONFIG=(orcl11020,stdby_11)'
*.log_archive_dest_1='LOCATION=/<dir>/flash_recovery_area/ORCL11020/archivelog
VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=orcl11020'
*.log_archive_dest_2='SERVICE=stdby_11 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) db_unique_name=stdby_11'
*.LOG_ARCHIVE_DEST_STATE_1='ENABLE'
*.LOG_ARCHIVE_DEST_STATE_2='ENABLE'
*.LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'
*.LOG_ARCHIVE_MAX_PROCESSES=30
Copied same pfile for standby database and modified following-
*.control_files='/<dir>/oradata/stdby_11/stdby_11.ctl','/<dir>/fra_stdby/stdby_11/stdby_11.ctl'
*.db_name='orcl1102'
*.db_unique_name='stdby_11'
*.FAL_CLIENT='stdby_11'
*.FAL_SERVER='orcl11020'
db_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11'
log_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020/redo_mem','/<dir>/oradata/stdby_11/redo_mem'
standby_file_management=auto
*.log_archive_dest_1='LOCATION=/<dir>/fra_stdby/STDBY_11/archivelog
VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=stdby_11'
*.log_archive_dest_2='SERVICE=orcl11020 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
db_unique_name=orcl11020'
3. Add relevant information in tnsnames.ora and listener.ora files and then restart listener.
3. Created password file with same credential as primary database.
4.Up-to-date RMAN backup of primary database available.
5.Create standby controlfile with rman
While primary database s open (I tried with primary database in mount mode as well)-
$>rman catalog rman/paswd@rman target /
RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY;
6. Open a new terminal and startup standby database in nomount mode using parameter file created -
$>ORACLE_SID=stdby_11
$>export ORACLE_SID
$>sqlplus / as sysdba
SQL>STARTUP NOMOUNT pfile='<location/initfilename.ora'
SQL>quit
$> rman AUXILIARY / target sys/passwd@orcl11020 catalog rman/passwd@rman
RMAN>DUPLICATE TARGET DATABASE FOR STANDBY DORECOVER;
RMAN finishes without error but archive logs are not being tranported. Looking at the log, following caught my eye-
Error 1017 received logging on to the standby
Check that the primary and standby are using a password file
and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
and that the SYS password is same in the password files.
returning error ORA-16191
FAL[client, ARC2]: Error 16191 connecting to orcl11020 for fetching gap sequence
Errors in file /<>dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
ORA-16191: Primary log shipping client not logged on standby
Errors in file /<dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
ORA-16191: Primary log shipping client not logged on standby
So on both primary and standby I confirmed
SQL> show parameter remote_login_passwordfile
NAME TYPE VALUE
remote_login_passwordfile string EXCLUSIVE
To make double sure that password files are same, I shutdown both databases, delete password files and recreated with same credentials.
Password files are called - orapworcl11020 and orapwstdby_11
Can someone guide me where thisngs are going wrong here please.

Not sure if I understood it clearly.
SELECT * FROM V$ARCHIVE_GAP;
returns no rows so there is no gap.
But could you please explain me the result of the previous query. To catch up again, on standby when I check
SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
SEQUENCE# APPLIED
75 NO
74 NO
76 NO
77 NO
I understand that though archive files have been copied across but they are not applied yet.
On primary when I give your query -
SELECT name as STANDBY,SEQUENCE#,applied, completion_time
2 FROM v$archived_log
3 where dest_id=2
4 and sequence# BETWEEN 74 and 80;
I get -
STANDBY SEQUENCE# APPLIED COMPLETIO
stdby_11 74 YES 28-JUN-11
stdby_11 75 YES 28-JUN-11
stdby_11 76 YES 29-JUN-11
stdby_11 77 YES 29-JUN-11
stdby_11 78 YES 29-JUN-11
stdby_11 79 YES 29-JUN-11
stdby_11 80 YES 29-JUN-11
stdby_11 75 NO 07-JUL-11
stdby_11 74 NO 07-JUL-11
stdby_11 76 NO 07-JUL-11
stdby_11 77 NO 07-JUL-11
stdby_11 78 NO 07-JUL-11
I have intentionally given
sequence# BETWEEN 74 and 80
because I know in the current incarnaion of the database, max sequence is 78.
So my understanding is, the rows between 28-29 June are from previous incarnation, correct me if I am wrong
Archive files of the current incarnation, since I successfully created standby database are shipped but yet to be applied - am I right?
Then my final question is, when will these archives be applied to standby database?
I am sorry to ask too many questions but I am just trying to understand how it all works.
Thanks for your help again

How to create new database with rman backup

hi,
i took a rman backup with nocatelog. can i make a new database with that rman backup.
if yes then how ? i m using oracle 9i.

'NEW' doesn't seem to be the right word here, but you can DUPLICATE (clone) an existing database or restore it to a new host:

Backing up remote databases with RMAN?

Hi there
Implementing RMAN (10g) for the first time, and have a few general questions.
We want to use RMAN to backup a number of remote instances.
1. What would be the architecture for this? Would i have a single, central RMAN instance ie a blank database with only a rec cat installed, and from there have all the target databases connecting in?
2. How would these remote target dbs communicate with the RMAN instance? TNS? dblinks?
I know they have to be registered with the RMAN instance, but how would they be recognised to begin with?
3. If i'm backing up to storage, does the storage need to be connected to the RMAN server, or the target database server?
I know these are probably really basic, but i've read through the manuals and these questions aren't adequately answered.
Thanks in advance to all who answer!
Rup

1. Its always a good idea to have seperate recovery catalog database, in case of a database loss, you have your backup information on other database.
2. you can connect rman to target database as
connect target /
or
connect target user/pass@mylink
connect catalog catuser/catuser@catdblink
when connecting for backup, you have to connect to target (which you want to backup) and then to catalog database , so RMAN knows which is to backed up and where to catalog
3. in all cases, rman will generate backup sets on target database server, you will have to nfs mount your storage to that server, if using tape library, then configure media manager for that target

Standby Database with RMAN on ASM

Hi,
I am using redhat Linux AS 4 and my database is 10.2.0.1. This database used ASM for storage of data files, control files, online redo logs. Flash recovery area is also configured in the ASM.
I want to create a physical standby database on a different machine by using RMAN. Can someone kindly point me to some easy to follow document? I have scoured the oracle docs, but am more confused than ever.
regards

ORA-19602 during backup of a RAC database with RMAN

Dear All,
We have an Oracle 10g database on a 2 nodes. This database is running in noarchivelog mode. While doing an offline backup of this database, we encountered ora-19602 errors. See below:
channel ORA_DISK_1: backup set complete, elapsed time: 00:00:55
channel ORA_DISK_1: starting full datafile backupset
channel ORA_DISK_1: specifying datafile(s) in backupset
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 03/30/2009 09:56:10
ORA-19602: cannot backup or copy active file in NOARCHIVELOG modeBelow were the steps that we followed:
1. We stopped both instances using "srvctl stop instance -d test -i test1,test2"
2. We then "rman target /"
3. In RMAN, we "startup mount"
4. In RMAN, we "backup database;"
5. RMAN failed with the above errors
Can someone advice what went wrong? Thanks!

Hi..
1. We stopped both instances using "srvctl stop instance -d test -i test1,test2"
2. export oracle_sid=sid
3. We then "rman target /"
4. In RMAN, we "startup mount"
5. In RMAN, we "backup database;"
Changed step 2.
Also, from sqlplus can you check the
select name,open_mode from v$database;
select STATUS from v$instance;

Backing several databases with rman does require one catalog/

Thanks in advance. I've never liked RMAN, but now I need to get smart on how to best use it.
Please advise on the following:
1. I have several databases that need to be backed up using rman
2. I've create a new database that will be used to backup all of the databases
3. Will I need to create one catalog for all of the databases that will be backed up or do I create one catalog for each database that will need to be backed up? Thanks for any other advise
Additionally I'll be backing up two RAC databases.

If you use 11g, you shouldn't do it. In 11g, you can even duplicate database without taking any backup

Duplicating a Database

RAC11g
Hi
I am duplicating a database with RMAN duplicate.
I set the parameters db_file_name_convert, log_file_name_convert on both instances of target database. The target database is a production database. I know I have to shutdown both instances and after start them for having the parameters on both. Accidentaly I shutdown one of them and up to I shutdown the another the instance1 is not going to be started because the instance tell me that the parameters have to be equal on both. I know that If I shutdown instance2, after both instances are going to be fine but I can not do it because I can not close the database.
Instance1 have the parameters originaly so:
SQL> show parameters convert
NAME TYPE VALUE
db_file_name_convert string
log_file_name_convert string
and the instance1 has these parameters with values that I set.
What I want ?. Clear these parameters on instance1 again for starting it again.
I know I can modify parameters of instance1 from instance2 but the values seems to be bad....
for example:
when I tro to clear the parameters from instance1 I get the following error:
SQL> alter system set db_file_name_convert='','' scope=spfile sid='instance1';
alter system set db_file_name_convert='','' scope=spfile sid='COFASADB1'
ERROR at line 1:
ORA-01078: failure in processing system parameters
LRM-00117: syntax error at ',' at the start of input
SQL>
what is the correct value to clear the parameter ?
Thanks

Hi
I removed the parameters with alter system reset <parameter name> scope=spfile sid='*';
Now I have set the parameters only in auxiliary database but it seems... it is looking for to retore on production dbfiles....
Both databases are RAC databases and they are on the same hosts.
I have done several duplicates in RAC enviroment from RAC Database to single instance inside these hosts without any problem.
I am doing the duplicate from node2 connecting to the production database instance2 and auxiliary database in instance2 as well.
Thanks

Duplicating DB with RMAN,DB mode:NOARCHIVE LOG?

Hello,
I want to get a duplicate database on a remote server machine with same file structure by using internet of VPN(virtual private network). My question is ...
can we duplicate the database to remote server if the Database is in NOARCHIVELOG MODE ??
I have surffed on net for the same i got the method to duplicated the database but not sure weather i can do that in noarchivelog mode !
Regarding the steps if anyone has some better ideas to perform duplication of Database with RMAN or any other tool let me know or any more optimized steps ....will be appreciated. But please keep this point that the database is in norachivelog mode.

Thanks in advance....

If the database is in noarchivelog mode, then you can only take offline backup of database through RMAN in the mount state. Previously database shouldn't be shutdown

Create a clone database form rman catalog !

Dear Friend ,
I have a rman catalog database . I am using this rman catalog for against a database name 'testdb' . Everyday I take rman full backup of the testdb using the catalog database .
Now I create a another database which will be the clone of the testdb . I want to create it using that rman catalog database . Can I create a new database using the catalog database ?
If yes, then plz help me to give some directions .....

Creating a Standby Database with the Same Directory Structure

Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.

Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks.

Database migration from non rac and non asm to RAC database with ASM

HI,
i have requirement to import one database ( db1) which running one node with out ASM and with out RAC , now i want to import that database with rman backup to another database ( db2) which running on different server with 3 node RAC and ASM ( disk group +DATA ) , can you please provide me the steps how i can migrate.? ( i have created db2 with dbca with RAC).
regards,

Sri,
This could be done multiple ways. Simplest for you is to use DBCA:
