RMAN for dataguard
hi all,
Currently am reading the doc http://download-uk.oracle.com/docs/cd/B28359_01/server.111/b28294/rman.htm#BAJEDHFB
In that under 11.3.2 it says to configure deletion policy of 'applied on standby' to delete applied logs on standby....Studying further 11.3.4 it says the same configuration to be done in standby where backups are not performed..
my db is 10.2.0.4 and having a physical standby db where backups are not performed...Do u need to set the 'applied on standby' configuration both in primary as well in secondary'..
thanks,
baskar.l
Hi
See, as per your requirement whether you would to like have logs available for future use, go for applied policy.

Configuring rman for dataguard environment.
Hi all,
Here we have a dataguard environment with db1 as primary and db2 as physical standby database. We configured dataguard in 10g environments and we are not using grid control. Can anyone provide the steps for configuring rman for incremental backups in this environment? We want to schedule the backups to be taken in standby db, (that is applicable in case of swithover too). In the case of swithover to db2 what all do we need to do in rman manually to resume backups in db1?
ThanksHello;
A Standby database is a copy of the Primary so if you try to register it RMAN will probably tell you its already registered. I would start with this :
Standby based backup
1. Enable auto backup of the control file and server parameter file. CONFIGURE CONTROLFILE AUTOBACKUP ON.
2. Skip backups on datafiles already backup. CONFIGURE BACKUP OPTIMIZATION.
3. Set the archive deletion policy. CONFIGURE DELETION POLICY TO NONE.
You have to decide on the exact RMAN script you want to use, but since the database is registered you can perform backup on either the Primary or the Standby as the need arises.

Configuring RMAN for dataguard.
Hi all,
Here we have a dataguard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. For both primary and secondary the ORACLE_SID is 'oracledb'.We configured dataguard in 10g environments and we are not using grid control. And now we want to configure rman for incremental backups. We are using a third catalog database to which we registered from primary db successfully. During primary rman configuration it is showing conflicts. Even the changes made in primary RMAN configuration are applied on to the standby too which i think shouldn't happen in this scenario. How to resolve this issue? Is this happening because of the same ORACLE_SID for both primary and secondary? I'm attaching the link of the doc that we followed also the errors and configuration in rman. Can anyone help?

RMAN and dataguard wout catalog?
Hello,
We used RMAN for backups and recently implemented a dataguard environment in 10g r2(physical standby). While perusing upgrading to 11g I came across instructions saying you must use a recovery catalog in a dataguard environment. The backups are running on the primary just using the control file and all seems to be working. I did a 'restore database validate' and it succeeded. Is the recovery catalog only necessary if I chose to do the backups on the standby - or is a catalog required in my scenario?
Thanks,
Mark
Edited by: user6061469 on Apr 20, 2011 11:43 AMYou were able to build your standby without using a catalog.
You are able to take backups of your primary without using a catalog.
Where does it say (in the documentation) that a recovery catalog is required ?
With the enforcement of DB_UNIQUE_NAME you can use the same catalog for Primary and Standby backups -- if you run backups from both locations. That is an enhancement. But not a requirement if you don't need to or plan to backup both sites and use a common catalog.

what is SBT here?
CONFIGURE DEVICE TYPE sbt PARALLELISM 3;
Channel Connections to Cluster Instances with RMAN
Channel connections to the instances are determined
using the connect string defined by channel configurations.
For example, in the following configuration, three channels are allocated using dbauser/pwd@service_name. If you configure the SQL Net service name with load balancing turned on, then the channels are allocated at a node as decided by the load balancing algorithm.
CONFIGURE DEVICE TYPE sbt PARALLELISM 3;
CONFIGURE DEFAULT DEVICE TYPE TO sbt;
CONFIGURE CHANNEL DEVICE TYPE SBT CONNECT 'dbauser/pwd@service_name'Edited by: nisha on Jun 6, 2011 12:27 AM -
Very first step in configuring RMAN for a Backup
DB version:10gR2
I am a DBA supporting applications development and i am not familiar with RMAN. This weekend we are going to Patch 10.2.0.1.0 to 10.2.0.3.0. Before that i am going to take a backup of the entire Database containing around 57 schemas(total of around 600gb).
We don't have Tape drives. I am going to backup this up on three filesystems in the same machine. This instance is not running on ASM. What is the first step i should be doing in configuring RMAN for a backup?
Edited by: user10583227 on Jan 27, 2009 4:50 AMBe careful, three filesystems doesn't necessarily mean the use of three channels. Could be more...could be less.
Are you in a position to shutdown the database? If not, you'll also want to backup the archivelogs with BACKUP DATABASE PLUS ARCHIVELOG. You may also consider creating a Guaranteed Restore Point which would allow you to rollback your database in minutes if the upgrade fails. -
Backup procedure using RMAN for 11i Instance
Hi,
we have 11.5.10.2 instance
Node 1 = Application Tier ( 11.5.10.2)
Node 2 = DB Tier ( 9.2.0.7)
as of now, we are taking daily cold backup of both instances.
we want to implement RMAN online backup for DB and take cold backup every week end only.
so, what are the best procedures for implementing RMAN for 11i Database.
Please share your experience, if you have anybody implemented?
which one you prefer in RMAN backup ( backupsets or copy option or backupsets with compressed option) interms of performance.. our db size is 60 GB only.
we apply apps tier patches very rarely . so we want to take RMAN online backup for DB daily and take cold backup for entire apps and db in the week ends.Hi,
This time, i am going to implement for Oracle 11i Database. thats why, i need you guys advice regarding 11i Database.Well, the same is applicable to 11i/R12 databases. You just need to configure RMAN the same way you configure it on any standalone database.
If you have implemented any where RMAN, can you share, how you are taking RMAN backup? I can share the scripts we use for backup using RMAN. If you are interested, let me know and I shall send it by email.
if we want to clone, are you cloning the TEST instance with RMAN backup or using cold backup.We use both, depends on the time frame of the cloning task and whether it is possible to use cold backup for cloning or not.
Please have a look at the following notes, it should be helpful.

Using RMAN for creating a Dataguard Standby db.
Hello,
I have two 11.2.0.1.0 oracle instances running on two cloned Red Hat Enterprise Linux (rhel98 and rhel99). Linux version:
Linux rhel99 2.6.32-100.34.1.el6uek.x86_64 #1 SMP Wed May 25 17:46:45 EDT 2011 x86_64 x86_64 x86_64 GNU/LinuxI am trying to perform a "duplicate target database for standby" as part of the list of steps to get a Physical Standby located at the rhel99 server with DB_UNIQUE_NAME ORCL99. But I am missing something because it keeps failing with this error:
RMAN-05556: not all datafiles have backups that can be recovered to SCN 2818790
RMAN-03015: error occurred in stored script Memory Script
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 5 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restoreI double checked the directory structure on primary (rhel98) and standby (rhel99), and it's the same. As control file is restored during the duplicate process I cannot perform the catalog start with, so the backups were placed on the same locations at rhel98 and 99.
According to that error message it is not finding any of the datafile backups.

Edited by: martin.morono on May 29, 2013 8:56 PMThanks Hemant but the issue is the same with sequence 6 or 22. I posted the RMAN log from an old duplicate I ran yesterday using sequence 6, but as you can see below the error is not changing with setting "until sequence 22"
Hemant K Chitale wrote:
Your database datafile backups are as of Checkpoint SCN 3100062 which is higher than the archivelogs (and certainly higher than SEQ#6).
Possibly SEQUENCE#22 will cover the database checkpoint SCN. Therefore, the minimum UNTIL SEQUENCE would be 23 or higher.

Third party backup software support for dataguard configurations
Any Oracle document about the subject?
I would be interested in an answer about backupexec 2010 r2 in particular, because reading the manual for its oracle agent there is information about Oracle/RMAN and RAC support, but nothing about Dataguard integration, that could be a value added.
Anyone using third party backup agents in a Dataguard configuration?
Interested in version 11gR2 on Linux.
Thanks,
Gianlucayes, you should be able to use the full backup taken in middle and use the rest of the log backups taken afterwards to restore the database.while I do not use TSM, we use QUEST(DELL) LITESPEED, that takes full backup once a day and log backups
every 15mins.
if someone accidentally takes full backup in the middle of day with out 'copy only',
log sequence will break and successive log backups depend on this full back up.
while this should be prevented from happening in first place, you can still restore from native full backup and then apply log backups taken from third party taken after the native Full backup.
if this happens, I would restore the FULLBACKP with NORECOVERY using NATIVE SQL and then use lite speed syntax to restore the log backups.Remember, native sql cannot read third party formatted backups(atleast litespeed), thats why I restore the full backup
using native sql, since it was taken with native sql backup and log backups using litespeed syntax.
Hope it Helps!!
Thanks, well it was just a theory discussion we had about the issue. But none of us could find info on the internet easy to prove our point :) Thanks. -
There is request to take cold backup of primary & standby db , i am New to dataguard backups, Should i take backup of only primary db or both?
Yes apps owner is insisting to take cold backup of both db this weekend(they are patching apps), and here are the step i had in mind to do that to stop , primary & llogical standby dbs , take cold backups ( scripts, usermanaged backups, dont have rman there) & start the dbs.
On standby db
SQL > set numformat “999999999999999”
SQL > select newest_scn,applied_scn from dba_logstdby_progress ; (both should match)
SQL > select thread#,sequence#,applied from dba_logstdby_log;
SQL> select sequence#, status from v$archived_log;( on primary) Both sequence# should match
on primary db
SQL > alter system switch logfile ;
SQL > alter system archive log current ; ( to make sure current transactions come thru)
check tail of alert log of standby to make sure these redologs shipped & mined
standby db
SQL> ALTER DATABASE STOP LOGICAL STANDBY APPLY; (stop SQL Apply)
SQL> shutdown immediate;
Lsnrctl stop listener_corp_remrpt-haprimary db
SQL > shutdown immediate ;
Lsnrctl stop listener_corp_remprd-ha
Dont shutdown abort for any case, if both dbs are going down, first stop SQL apply on standby, take primary down and then take standby down)
Startup
primary
SQL>startup;
Lsnrctl start listener_corp_remprd-ha
Standby
SQL > startup
SQL > alter database start logical standby apply immediate ;
Lsnrctl start listener_corp_remrpt-ha -
RMAN and Dataguard (10g)
Hi all,
I know this topic has been discussed several times over on this forum, but I have a peculiar situation.
I have just inherited a client system with 10g and DataGuard with RMAN. The standby is Physical and both nodes are on HP-UX version and patchsets.
The standby is persistently idle. The client insists on backing up the physical standby only.
My question is this, is there any danger in backing up on the physical standby?. I've argued the case that we should backup the Primary and Standby to no joy. I am a little worried that we may experience a failure on the primary and start a recovery with backup taken from the Standby node. Is this feasible at all?
Please confirm that I am right.
Regards,
Timothy.Having a recovery catalog, there's a resync with the standby controlfile after the backup, the backup informations are now in the catalog. Now when you need to restore/recover the primary database you connect to this and to the catalog. Primary and standby are clones , so you access the same record in the catalog regardless whether you are connected to the primary or to the standby. Because of this a resync will refresh the primary controlfile with the backup records which were taken while connected to th standby. A simple backup/recovery example looks like this:
1) connect target sys/pwd@stdby catalog rman/pwd@rmancat
2) backup database; (resync happens automatically after this)
4) connect target sys/pwd@prim catalog rman/pwd@rmancat
5) resync catalog;
6) restore database;
7) recoverer database:
It's not mandatory, but recommended to backup the archivelogs on the primary side. Here you are sure to have all archivelogs (at least under regular circumstances). For many reasons it could happen, you miss some archives on the standby side.
It's possible to run a standby in read-only mode for reporting purposes. In this case archivelog applying is suspended. If you have such a situation it's not recommended to backup the standby database, possibly it does not change for a long time and in case of recovery you have to apply a large number of archivelogs.

Restoration of ASM/RAC database to another clustered set of servers for DataGuard implementation
Hi all,
I've been working with single instance Oracle DBs for several years and we're now looking into RAC. I'm trying to gather as much info as possible in areas I think may be challenging if/when we implement RAC.
Can someone please help me with some info with regards to the scenarion below:
Assuming I already have a 2 node RAC database running and I want to set-up a failover RAC database, would the following steps be correct(assuming 11g):
Configure hardware, networking and O/S for 2 node RAC cluster (I know there's a lot in this single line, but let's just assume that's all done)
Configure disks for ASM
Clusterware installation
Oracle ASM software installation
Oracle11g software installation with RAC option
Database creation
***I'm not sure of the steps after database creation:
Export primary database up to a specific SCN (data pump gives the ability to specify scn)
Import into failover database
Switch on dataguard and sync failover starting from scn specified at export.
Please, help correct these steps and any useful link where this process is treated thoroughly would be highly appreciated.This is a very high level overview of the steps, but here are some additions/amendments I can make:
Clusterware installation
Oracle ASM software installation
-- The above 2 steps are done at the same time. In 11g, the Oracle 11g Grid Infrastructure includes both the Clusterware and ASM installation and configuration.
Oracle11g software installation with RAC option
Database creation
***I'm not sure of the steps after database creation:
Export primary database up to a specific SCN (data pump gives the ability to specify scn)
Import into failover database
Switch on dataguard and sync failover starting from scn specified at export.
Will you be using Data Guard for a physical standby? If so, using RMAN would be the correct method in creating the standby database. The general steps would be:
- Oracle 11g software installation
- Backup Primary Database
- Configure Data Guard Parameters on Primary
- Duplicate Primary to Standby RAC using RMAN (can be done manually or through the RMAN DUPLICATE command)
- Enable log transport from primary, enable managed recovery on standby, and verify log transport and apply is working as intended.
Again this is a very general overview on the entire process, there are other factors that you'll have to take into consideration when planning such a project:
- Which protection mode will you be using? Maximum Performance, Availability, or Protection? The business' recovery goals and SLAs will be able to determine which mode you will choose.
- Will the standby be used for reporting purposes?
- Recommended to have your standby site have the same hardware configuration as the primary.
- Do you have an EM site already set-up? Data Guard Broker should be considered in the configuration of the Data Guard environment.
This is just a few things quickly off the top of my head. What OS do you have/plan on using? I don't have the link handy on me at the moment, but the official Oracle documentation should provide detailed guidance.
EDIT:
At a bare minimum, read the 2 Day RAC Guide. There is more detailed information in the RAC Admin and Deployment Guide, as well as the Data Guard Concepts and Admin Guide. Also here's a step-by-step guide provided by Oracle. You can also find several blogs that provide a more concise step-by-step guide, such as here, here, and here. RACSIG also has a number of very useful whitepapers, but something seems to be wrong with their search function and I can't link anything at the moment. However, I would highly recommend reading through the official documentation as this has more comprehensive information, especially if you are deploying on a production system.

Oscar
