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.
ORACLE 10g R2
Windows server 2003 32bit
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
abnormally.

SQL> shutdown immediate;
Database closed.

RMAN backup in noarchived log mode

Hi,
can we take RMAN backup in noarchived log mode?
If yes, how? just run backup database command or ?
thanks

You can use RMAN to backup a database in noarchivelog mode but you need to shutdown and mount the database. e.g.:
rman target /
RMAN> shutdown immediate
RMAN> startup mount
RMAN> backup database

Physical standby with rman: location of redo logs

guys,
i use simple rman commands to create a physical standby database (i've attached the commands below). the problem is that on the physical standby, the location of the redo logs and standby redo logs differ from the primary.
(we use redo logs and standby redo logs as we are running in max. availability mode and want to be prepared for switchover/failover).
how do i backup/restore the database in a way that the redo logs are at the same place than on the primary database?
thanks for your help,
heri
backup on primary:
backup incremental level = 0 format '/tmp/transfer/td_%s_%p.bck' database;
restore on standby:
duplicate target database for standby NOFILENAMECHECK;

Ogan,
thanks alot for your reply. I was not using the log_file_name_convert parameter as i am not aware how to use it in this scenario. the log files on the standby are generated randomly.
on the primary the log files are as follows:
/home/oracle/app/oracle/oradata/td/redo01.log
/home/oracle/app/oracle/oradata/td/redo02.log
/home/oracle/app/oracle/oradata/td/redo03.log
/home/oracle/app/oracle/oradata/td/standby_redo01.log
/home/oracle/app/oracle/oradata/td/standby_redo02.log
/home/oracle/app/oracle/oradata/td/standby_redo03.log
on the standby the logs look like:
/home/oracle/app/oracle/product/11.2.0/dbhome/dbs/TDSTBY/onlinelog/o1_mf_1_6b1f9mvc_.log
/home/oracle/app/oracle/product/11.2.0/dbhome/dbs/TDSTBY/onlinelog/o1_mf_2_6b1f9p36_.log
/home/oracle/app/oracle/product/11.2.0/dbhome/dbs/TDSTBY/onlinelog/o1_mf_3_6b1f9rdj_.log
/home/oracle/app/oracle/product/11.2.0/dbhome/dbs/TDSTBY/onlinelog/o1_mf_4_6b1f9v8r_.log

/home/oracle/app/oracle/product/11.2.0/dbhome/dbs/TDSTBY/onlinelog/o1_mf_6_6b1f9zxv_.log
the filenames on the standby are not predictable for me in any way, so how would i use log_file_name_convert?
thanks alot for your help!

Standby db in R/W mode with RMAN

Hello,
I have a test environment that I have a physical non-managed standby database created in a virtual machine. I would like to use a physical standby database for read/write testing and reporting. I've been implementing the Data Guard Scenarios and tried to see if I can revert the activated database back to a physical standby database. However, I keep receiving the following error when I try to open the standby in read only mode:
ORA-16004: backup database requires recovery
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\SYSTEM01.DBF'
Note: The standby db starts up as follows:
startup nomount pfile=C:\oracle\product\10.2.0\db_2\database\initORCLstdby.ora;
alter database mount standby database;
Once every x minutes, a batch job ships the logs from the primary to the secondary and runs the following:
connect / as sysdba
spool c:\scripts\logapply.log
alter database recover automatic standby database until cancel;
alter database recover cancel;
Here's the steps I've done:
1. On the standby database, query the V$DATABASE view and record the current SCN of the standby database:
SQL> SELECT CURRENT_SCN FROM V$DATABASE;
CURRENT_SCN
1804721
2. This step didn't work/isn't necessary:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL
ERROR at line 1:
ORA-16136: Managed Standby Recovery not active
3. Connect to the standby database as the RMAN target and create an incremental backup from the current SCN of the standby database that was recorded in step 1:
RMAN> connect target "system/password"
connected to target database: ORCL (DBID=xxxxx, not open)
RMAN> BACKUP INCREMENTAL FROM SCN 1804721 DATABASE FORMAT 'C:\tmp\ForStandby_%U' tag 'FOR STANDBY';
4. Connect to the standby database as the RMAN target, and catalog all incremental backup pieces:
RMAN> CATALOG START WITH 'c:\tmp\ForStandby_';
5. On the primary database, switch logs so the SCN of the restore point (created in step 1) will be archived on the physical standby database and ship it to the standby database:
SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
6. Activate the physical standby database:
SQL> ALTER DATABASE ACTIVATE STANDBY DATABASE;
SQL> STARTUP MOUNT FORCE;
SQL> ALTER DATABASE OPEN;
Make any write changes on the activated standby database.
7. Revert the activated database back to a physical standby database.
SQL> STARTUP MOUNT FORCE;
Connect to the standby database as the RMAN target and apply incremental backups
Open another session for RMAN:
RMAN> RECOVER DATABASE NOREDO;
Back to SQL session
SQL> ALTER DATABASE CONVERT TO PHYSICAL STANDBY;
SQL> SHUTDOWN IMMEDIATE;
I then run a batch file that automatically start the standby database and recover from the shipped archive logs:
startup nomount pfile=C:\oracle\product\10.2.0\db_2\database\initORCLstdby.ora;
alter database mount standby database;
SQL> alter database recover automatic standby database until cancel;
alter database recover automatic standby database until cancel

I've tried another approach to step 7:
SQL> STARTUP MOUNT FORCE;
SQL> ALTER DATABASE CONVERT TO PHYSICAL STANDBY;
SQL> STARTUP MOUNT FORCE;
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;
I get an error if I try this:

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT
ERROR at line 1:

When I try to open the standby database in read only mode, I get this error:
SQL> alter database open read only;
alter database open read only
ERROR at line 1:
ORA-16004: backup database requires recovery
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\SYSTEM01.DBF'
I ran SELECT SEQUENCE#, FIRST_TIME FROM V$LOG_HISTORY; and found that the standby sequence# is only one sequence behind the test primary database.
I'm stuck and would appreciate any help. Thank you.

And how do you think you will conserve disk space with RMAN ?
Stop and think about it : How can you revert a database AFTER you have Opened
it Read/Write ? You need to flashback it OR restore it from a backup taken before
the OPEN.
So, you could have taken a backup to Tape or to alternate disk before OPENing the
database. The backup to alternate disk can be via Flashback Recovery area or
a regular RMAN (compressed, you want ?) backup. In the second case, you wouldn't
be using a Flashback mechanism but a simple backup and restore method.

Why we cannot take hot backup if database is in noarchive log mode

Hi,
I am aware that if database is in noarchive log mode, we cannot take hot backups and only cold backup is possible.
I would like to know the technical reason behind this restriction?
Thank You
Sarayu

Hot backups are fuzzy backups, inconsistent, in other words, since something is always happening in the database. When you recover, you restore data files and then apply redo to make the transactions consistent. You can do a complete recovery or recover to a point in time. So where does the redo come from? That's what we call archiving redo logs. When the online redo gets full, it gets archived.
In the case of an instance crash, the redo is there in the online redo logs, so Oracle can recover automatically. Anything beyond that, having to do with storage media, is a media recovery, and requires those archived logs. So unless you have some other way to get your data back, always run in archivelog mode.
It is really important to understand the concepts. Please read the docs.

http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmintro.htm#i1005488
It may be worth your while to get a third party backup and recovery book too.

Rman backup and restore noarchive log

Hi,
We are changing our backup tools from exp to rman. For this I am trying to do
restoration in test server of oracle db running on 9.2 noarchive log.
Step 1. Taken complete backup with rman with nocatalog and include controlfile
nput datafile fno=00008 name=D:\ORACLE\ORADATA\TOTO\TOOLS01.DBF
channel ORA_DISK_1: starting piece 1 at 09-MAR-06
channel ORA_DISK_1: finished piece 1 at 09-MAR-06
piece handle=D:\DBBACKUPS\T1.BKP comment=NONE
channel ORA_DISK_1: backup set complete, elapsed time: 00:01:15
Finished backup at 09-MAR-06
Step 2. Deleted database files and control files from database directory.
Step 3. Restore controlfiles
RMAN> restore controlfile from 'd:\dbbackups\t1.bkp';
Starting restore at 09-MAR-06
using channel ORA_DISK_1
channel ORA_DISK_1: restoring controlfile
channel ORA_DISK_1: restore complete
replicating controlfile
input filename=D:\ORACLE\ORADATA\TOTO\CONTROL01.CTL
output filename=D:\ORACLE\ORADATA\TOTO\CONTROL02.CTL
output filename=D:\ORACLE\ORADATA\TOTO\CONTROL03.CTL
Finished restore at 09-MAR-06
Step 3. after database mount, try to restore datafiles, which is failed
restoring datafile 00024 to D:\ORACLE\ORADATA\TOTO\DIN36\TESTUNV1.ORA

Why it is looking old backup totobkp.rman which is not existing on disk ? My
backup name is t1.bkp.
Will you pl tell me where I have gone wrong ? Secondly what are the correct
steps to be followed for taking cold backup and restoration.
thanks & regards
pjp

Okay let us ponder this for a moment:-
DB NOARCHIVELOG
It does not matter when you take the backup of controlfile because the database is in mount state and no changes are allowed to the db ( Checkpoints etc. )
DB ARCHIVELOG
It does not matter when you take the backup of controlfile because the database is continuously writing to the archivelog's.
End result should not be significantly different as to worry about whether to take backup of control file before or after backup.
Thanks

Hot back up and archive mode with RMAN

Just diving back into back up world...
I know I can do a hot back up of the Database with no archivelog option not using RMAN.
Just wonder if I can do it with RMAN with no Archivelog option?
TIA

Thanks. Without rman, you can do tablespace online
backup, using start and finish as far as I remember.This is true only if ur database is in ARCHIVELOG MODE. If its not then the only way to back it up is cold backup by either RMAN or without. In short you can do HOT/online backup ONLY if your database is in ARCHIVELOG MODE.
Now what u actually want tell us..

How to restore archive logs with rman

Hi,
here is the scenario:
we have lost everything because of disk failure.
we have a full cold backup and archivelog backups which were created after cold backup and were backed up with rman.
after restoring from cold backup, because archivelog backups do not exist in controlfile, how can we catalog archivelog backups and restore them?
could you give me the exact rman command for this?
Best Regards,
Kamil

cold backup means offline backup, you shut database normally and copy datafiles to another location.
i think operating system does not matter that much but it is RedHat Linux Enterprise Server.
backing up archivelogs whith rman script which is:
run {
allocate channel c1 type disk format '$BKUPLOC/arch_%d_%u_%s_%p.bkp';
change archivelog all validate;
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
backup archivelog time between 'SYSDATE - (30*60/(60*60*24))' and 'sysdate';
release channel c1;
so here is the details.
1. because everything is lost, we restored all files(datafiles, controlfiles, redologs etc) from offline backup meaning copied all files from another location to corresponding location.
2. want to apply archive logs which were created after cold backup till disk failure and we have these archive logs with backups which were taken by rman.
So
first of all, we want to register these archive log rman backups(because these backup information does not exist in restored controlfile)
and then restore them and then apply them.
we need rman commands to register these backups and restore them.
Regards,
Kamil

I would recommend creating a new ASM diskgroup and assign Flash recovery area to this group. This is part of ASM best practices as in case your Data diskgroup goes, you can use RMAN backups/archivelogs for recovery purpose.

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 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

Problem with RMAN incomplete recovery

Oracle Version: 9i
Operating System: Windows 2000
I have a problem with RMAN incomplete recovery until sequence.
According to my database structure ............
SQL> SELECT GROUP#,SEQUENCE#,THREAD# FROM V$LOG;
GROUP# SEQUENCE# THREAD#
1 14 1
2 13 1
3 12 1
I took the backup of backup of full database using RMAN and i am trying to recover like this:
RUN
ALLOCATE CHANNEL C1 TYPE DISK;
SET UNTIL SEQUENCE 7 THREAD 1;
RESTORE DATABASE;
RECOVER DATABASE;
ALTER DATABASE OPEN RESETLOGS;
BUT i am getting a message saying there is no backup of DATAFILE 1,2,......10 to restore although my database is in archivelog mode and i took a backup.
Yachendra

Please consult v$backup_datafile.
It will tell you when the file was backed up.
RMAN will always search for a datafile backup prior to the logsequence or whatever is limiting the incomplete recovery.
Likely when you made your backup Oracle was already past sequence 7.

Recovery issue in noarchive log

Hi,
i need recovery for a database which is running in noarchive log mode.The dbas im my org take cold backup so they donot put the db in archive log mode. Now the database needs recovery it gets mounted but doesnot open and the db server asks me to apply the archive logfile which i donot have.i have also set the allowresetlogs_corrution to true. after restoring and performing the cancel based recovery the oracle server asks me for archive logfiles.i cannot perform incomplete recovery since the logifiles have been overwritten for a very long extend.
so at this stage how can i recover the database.
please provide me the essential steps.
I was provided this issue to solve.kindly help me.......
Thanks and Reagards

An inconsistent backup of a NOARCHIVELOG database is useless... Worse than useless, actually, if it provides a false sense of security that the database has been backed up and the data is somewhat safe.
I'm afraid the answer is most likely that the database is gone forever. If this is particularly valuable data, Oracle Consulting does have a tool (as do the ORA-600 folks in DUDE) that can probably recover most of the data from the data files. But these are not cheap utilities-- unless this is particularly valuable data, it may be more cost effective to toss the backups, find what data you can from other sources (old backups, old exports, other databases, etc) and chalk the cost of reconstituting the rest of the data up to the cost of hiring DBAs that didn't know what they were doing.
Doug Burns has a discussion on the [http://oracledoug.com/serendipity/index.php?/archives/789-DUDE,-Wheres-My-Data.html|DUDE data unloader]
I'd strongly suggest opening a Metalink ticket just to cover your own butt here. I expect them to tell you the same thing, but it's obviously a lot easier to go to management to tell them they've lost their data or that they need to write a check with lots of 0's to get it back because Metalink said so rather than because some guy on the internet said so.

Hot Backup with RMAN question.

Hi all.
We want to make a full backup with RMAN every night with the db up. Version 9i in archive log mode.
My question is if with the command:
backup database plus archivelog delete input format 'MY_FORMAT_STRING';
will store all the files needed for the recovery in one file or I need to backup some other file or do more actions. The backup will be consistent?
Regards.

By using this command you are only taking the backup
all the database files plus all the archived logs
needed for point on recovery.
But still you will have to take the backup of Control
file and parameter files. Which you do by configuringi think its not
RMAN> configure controlfile autobackup off
2> ;
old RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP OFF;
new RMAN configuration parameters are successfully stored
RMAN> backup database
2> ;

RMAN>backup database backup controlfile as well spfile but its better backup control file separately after backing up the database plus archivelog cause a backup set info within control file which will not be in control file which is just backed up by backup database .

Recovery with RMAN in case of complete lost of all files

Hi,
I am using RMAN in nocatalog mode to backup my databases to tape using the RMAN-Module for Legato.
I4ve read that in case of loosing all my controlfiles i cannot easily restore the controlfiles.
Lets assume the following scenario:
I am performing a daily full backup with RMAN in nocatalog mode. Approx. 2 hours after the completed backup my machine crashes and all files (i.e. OS-Files, Database, Controlfiles) are lost.
Now I have to reinstall the OS, reinstall Oracle and restore the backup.
Due to backups made with RMAN in nocatalog mode i have the restore the controlfies prior to restore the database. Metalink says restoring the controlfile from RMAN in nocatalog mode is not that easy.
Is there any way to restore the controlfile from RMAN in nocatalog mode in case of complete crash ??
Thanks.
Ronny.

RESTORE CONTROLFILE FROM 'filename...' doesn't appear to be supported in 8i.
What are the options for 8i?.
I have the backup sets with me from my previous installation before crash which also contains Control files.
However I am unclear as to how to proceed wit RMAN recovery with those files. There seems to be no way to point RMAN to those backupsets since RMAN apparently reads its information from catalog or the control file in case of nocatalog.
I think if there is a way to atleast restore the control file from the backup set, RMAN can proceed since it will find all the other backup details there.
Any help is greatly appreciated.
thanks
RP
