DataGuard with RMAN

Dataguard and RMAN.
Got Active DataGuard on a primary database, quite nicely sending its archive logs to its secondary.
I can quite happily use the Broker and switchover between them.
Now if I take RMAN backups of the primary database, if I have to failover to the secondary, I'm gonna loose all those backups.
Well, I can restore the whole database to the backup, cos I can restore the control file, from the backuip and therefore I can restore the whole db.
But if I want to restore to a tablespace, I wont be able to , cos the db_unique_names names are different, and the DB ID's will be different.
Same goes if I use a recovery catalog....
so how do I failover/switchover without loosing my previous rman backups ??

If I were backup up to Disk than I would come later and back up the back ups to Tape.
Since a Standby and Primary are the same database with the same DBID you can backup from either server.

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

Oracle 3113 creating a standby with rman

Hello,
environment is 11gR2 on Linux.
Tested on CentOS 5.5 as OS and local LAN as interconnect and the duplicate command terminates successfully in some minutes.
Same script but using oel 5.5 and a wan (3Mbit/s) and I keep getting 3113 errors after about 2h or 3h.
I suspect some timeout on wan (that is over vpn) but I would also like to trace something at my side.
I run a shell script with nohup and send it to background and this is the log, from which you can see the rman script:

BTW: what is the minimum size of undo tbs? Can I have compression enabled also during duplication if transport service is configured with COMPRESSION=ENABLED, or does it count only when copying redo files?
Thanks in advance,

Thanks for your reply.
I will try your suggestion as it could come useful some time.
So with this alternate method at the end I would have standby aligned as of backup time, correct?
And after running something like this on standby:
SQL> alter database recover managed standby database disconnect from session;
It will begin to receive, archive and apply redo logs, correct?
Some answers regarding the original question. It was confirmed that there was a 2hours cut-off time at firewall level.
The first datafile that the rman session began to copy was 3.2Gb in size, taking more than 2 hours completing.
Monitoring with netstat on source and target I saw this at source during the duplicate process:
tcp 0 0 10.49.1.93:46626 192.168.12.41:1521 ESTABLISHED
tcp 0 0 10.49.1.93:46627 192.168.12.41:1521 ESTABLISHED
tcp 0 0 10.49.1.93:46629 192.168.12.41:1521 ESTABLISHED
tcp 0 369240 10.49.1.93:50371 192.168.12.41:1521 ESTABLISHED
and the session bound to port 50371 was the only one pushing data (send queue not empty).
The other 3 ones I presume are for control of rman session. I get 3 sessions even if I open only one channel on primary side.
After the first datafile completes copy, a new session (with port 14871) is established substituting the other one.
The three initial ones instead remain for all the duplicate process.
tcp 0 487872 10.49.1.93:14871 192.168.12.41:1521 ESTABLISHED
tcp 0 0 10.49.1.93:46626 192.168.12.41:1521 ESTABLISHED
tcp 0 0 10.49.1.93:46627 192.168.12.41:1521 ESTABLISHED
tcp 0 0 10.49.1.93:46629 192.168.12.41:1521 ESTABLISHED
So after the copy of the first file, the session come back to one or more of the initial 3 ones, and they probably make a push-ack, got a 3113 as the firewall has silently cut them after 2 hours.... and the datafile, even if completed, is not marked as completed. A new run would copy again it...
Now the time has been put to 8hours, with 24hours being the maximum value set (no disable possible as far as the network guy said...).
And the duplicate completed correctly.
Would I have to fear any problems with this cut-off due to "normal" dataguard operations or not, in your opinion?
Thanks
Gianluca

Recovery Logical Standby with RMAN

Hi All,
I have a test environment with Primary DB Server, Physical Standby and Logical Standby.
The Logical Standby DB (cur_log_stdb) is backed up every evening by RMAN and I have a question:
If I recover my Logical Standby DB from backup and switch replication to new Logical Standby DB (new_log_stdb) it will work or not?
My steps e.g.:
1. Make a new server for my new_log_stdb and repair structure of catalogs;
2. Repair listener.ora and tnsnames.ora files from cur_log_stdb to new_log_stdb;
3. Restore DB with RMAN from backup to new_log_stdb;
4. On cur_log_stdb execute "alter database stop logical standby apply";
5. Change a DNS name from cur_log_stdb to new_log_stdb;
6. On new_log_stdb execute "alter database start logical standby apply immediate";
I'm not sure that archivelogs will apply to the new_log_stdb for period since rman backup was created.
Configuration:
Oracle Linux 6.4
Oracle Database 11.2.0.3
Primary and Physical with Data Guard

You might get better responses in the DataGuard forum ("space").
I am sceptical if this plan would work.

After every resetlogs you have to take fresh backup.
It seems you have opened your database in resetlogs and your backup is prior to this resetlogs.So the controlfile is showing inconsistance with the other datafiles.

Migrating with RMAN from 10g to 11g

Hi gurus,
I am following the following procedure to migrate database from 10g to 11g using rman
Source side:
RMAN>connect target
RMAN>backup database;
RMAN>backup archivelog all;
RMAN>backup current controlfile;
SQL> create pfile from spfile;
Copied datafile, archivelog backup files and pfile and password files to target side. i.e. on 11g server side
Target side:
Set proper parameters for 11g
SQL>startup nomount;
RMAN>connect target
RMAN>set dbid=<source database id>
RMAN>catalog start with '<rman backup file location';
RMAN>restore controlfile;
RMAN>run
set newname for datafile 1 to '<target datafiles location with file name';
restore database;
switch datafile all;
finished
upto now it's success full when i am trying to recover
RMAN>recover database;
it is saying
rman 00571
rman 00569
rman 00571
rman 03002
ora - 19698
can you please suggest the solution for this.
thanks a lot.

I'm not sure what you're doing is supported.
You are taking a 10g database and restore and recover it using 11g software.
I think you are allowed to do that with 10g software only.

I'm not sure that archivelogs will apply to the new_log_stdb for period since rman backup was created.
But if this plan won't work how can I restore Logical Standby DB from RMAN backup and resume replication from Primary?
Configuration:

Hello;
The only way to know for sure is to test it. You are asking somebody you don't know to confirm a recovery test for you. You have to perform the test yourself to be certain.
If your plan does not work you can always rebuild the Standby.

Auxiliary channel allocation in TSPITR with RMAN-managed instance

Hi,
I'm trying do perform TSPITR with RMAN-managed auxiliary instance. All backups are stored on tape. I need to send MML environment values while allocating auxiliary channel to connect to correct NetWorker server and send other NetWorker parameters.
Unfortunately I have issues with sending these params - I can't send them from recover RUN block, as auxiliary instance does not exists at the time when I'm starting to execute script. (example from test env using disk channels)
RMAN> RUN
2> {
3> ALLOCATE CHANNEL c1 DEVICE TYPE disk;
4> ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE disk;
5> SET NEWNAME FOR DATAFILE 1 TO '/u01/backup/tspitr/10gdb2/system01.f';
6> SET NEWNAME FOR DATAFILE 2 TO '/u01/backup/tspitr/10gdb2/undo01.f';
7> SET NEWNAME FOR DATAFILE 7 TO '/u01/backup/tspitr/10gdb2/hr_bak01.f';
8> SET AUXILIARY INSTANCE PARAMETER FILE TO '/home/oracle/params_auxinit.ora';
9> RECOVER TABLESPACE hr_test UNTIL TIME "SYSDATE - 1/4"
10> AUXILIARY DESTINATION '/u01/backup/tspitr/10gdb2';
11> RELEASE CHANNEL c1;
12> RELEASE CHANNEL aux1;
13> }
allocated channel: c1
channel c1: sid=141 devtype=DISK
released channel: c1

RMAN-06174: not connected to auxiliary databaseI know I can do it using configure, but is there any way to set this on session level?
10.2.0.4, RHEL
Thanks,
Lukasz

What can be done here, is to CONFIGURE AUXILIARY CHANNEL to set appropriate params for auxiliary instance (without allocating channels manually).
I just wanted to know, if I can do it just for this one session (without permanent modification). What I can do, is:
CONFIGURE AUXILIARY CHANNEL DEVICE TYPE sbt_tape PARMS 'mml settings';
CONFIGURE CHANNEL DEVICE TYPE sbt_tape PARMS 'mml settings';
CONFIGURE DEFAULT DEVICE TYPE TO sbt_tape;
RUN
(new names, auxiliary parameter file)
RECOVER TABLESPACE ...
CONFIGURE AUXILIARY CHANNEL DEVICE TYPE sbt_tape CLEAR;
CONFIGURE CHANNEL DEVICE TYPE sbt_tape CLEAR;
CONFIGURE DEFAULT DEVICE TYPE CLEAR;I just wanted more 'elegant' solution.
Update:
Due to bug no. 4768353 there is no possibility to use automatic channel allocation in auxiliary instance. Problem resolved by using own customized auxiliary instance started before recovery process. Channels have been allocated manually using ALLOCATE AUXILIARY CHANNEL c1 DEVICE TYPE sbt... on already running aux.
Thanks,
Lukasz

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

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.

Physical Standby Database Creation with RMAN

Hi,
I'm in 10g on Linux. I want to create a standby database on another Linux server. I did not find a clear procedure to create it in Oracle® Database Backup and Recovery Advanced User's Guide 10g Release 2 (10.2) Part Number B14191-02
and niether in Oracle® Data Guard Concepts and Administration 10g Release 2 (10.2) B14239-04
In the last one chapter 3 sends you to F appendix and F appendix says do nothing before having than all in chapter 3 :
In F.1.1 page F-2 it is said :
See Chapter 3 for a complete discussion of physical standby database preparation,including initialization parameter settings. You must perform all necessary preparation tasks described in these chapters before RMAN can successfully create the standby database files and mount the standby database.
Any way I'm looking for a procedure or clear article to create it.
Many thanks before.

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....
Regards,

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

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.

I had created a snapshot of the database(datafiles and archivelogs) and cataloged them.
CATALOG START WITH "+TBL_DG_DATA/ORCL/DATAFILE/" NOPROMPT;
catalog start with "+DG_ARCH/ORCL/ARCHIVELOG/" NOPROMPT;
The time i gave was after the snapshot was created.
When it failed the first time I created another controlfile using
sql "alter database backup controlfile to ''/tmp/auxpran/controlbc.ctl''";
And ran the recover command after the time after i generated this controlfile. Changed nothing else. TSPITR completed successfully. But it had failed first time. Cannot figure how it ran the second time but failed the first time.
