Data guard 11g vs 10g

Does data guard run in 11 g primary and 10g standby vice verca in any situation physical or logical.
Is the any possibility.

Hello,
You can find here a White Paper about "Data Guard" (and RAC) in Oracle 11g:
[http://www.oracle.com/technology/deploy/availability/pdf/dataguard11g_rac_maa.pdf]
In 11g, it seems (in §3.3) that the requirement about using the same Database version was "relaxed".
But OK! it's just a white paper and, I think that this point should be cleared in detail with Oracle Support
document.
Best regards,
Jean-Valentin

Using Oracle EM 11g with Active Data Guard 11g

Has anyone installed Active Data Guard 11g with OEM 11g for an active-active state or know if there are any installation procedures with these two products? We will be installing these products this year. Thanks, Cathy

If you already have both servers configured in Grid Control as targets, it should be fairly easy to create a standby database on server B. OEM has Availability tab on your primary database Instance section should have "Data Guard" section which has "Setup and Manage" option. You follow through the wizard, and it will generate a standby database on server B. Then you can convert your standby db on server B to Active Read-only database by clicking few more buttons.
If you do not have these two servers configured on your Grid Control, that would be the first task.
We set up three standby databases using Grid Control 11g in our test boxes, and they worked very well. Our biggest problem was to actually installing the Grid Control, but once installed, everything was easy.

License for Data Guard 11g - Observer

Hi,
I would like to know if fast-failover with Observer requires any additional licensing then just Data Guard.
Thanks in advance.

My first stop would be.... [Oracle 11g Licensing Information|http://download.oracle.com/docs/cd/B28359_01/license.111/b28287/toc.htm|Oracle 11g Licensing Information]. After that I would look at the Data Guard documentation.
HTH!

RMAN script failed while creating Data Guard 11g

Hi Friends,
I am creating Physical Standby (11g) using RMAN (ACTIVE) on windows using the doc : Step by Step Guide on Creating Physical Standby Using RMAN DUPLICATE...FROM ACTIVE DATABASE [ID 1075908.1]
The folder structure on Primary DB and on Physical Standby is totally different.
while executing RMAN script i got errors for lot of locations and i specified the proper location in RMAN script itself (ex set diagnostic_dest = 'c:\app\' , set db_recovery_file_dest='C:\app\flash_recovery_area')
Location of control files on Primary DB:
D:\oradata\MESSTG\CONTROL01.CTL
D:\oradata\flash_recovery\messtg\MESSTG\CONTROL02.CTL
Location of control files (planned) on Physical Standby DB:
C:\app\oradata\MESSTDBY\CONTROL01.CTL
C:\app\flash_recovery_area\MESSTDBY\CONTROL02.CTL
How to specify control file location of Physical standby in set control_files?
Also i have 2 control files on Primary DB so do i need to specify both the control files , if so how?
I tried different combination in RMAN script but all are failed:
set control_files='D:\oradata\MESSTG\CONTROL01.CTL','C:\app\oradata\MESSTDBY\CONTROL01.CTL'
RMAN Error is :

Hi,
Can you paste here you rman script ?
I think following script can help you.
duplicate target database for standby
from active database

set "db_name"="<DBNAME>"
set "db_unique_name"="<STANBYD DBA UNIQUENAME>"

set "log_file_name_convert"="C:\app\oracle\oradata\<dbname>","d:\oradata\<standbydbuniquename>"
set "db_recovery_file_dest"="D:\fast_recovery_area"
nofilenamecheck;C:\app\oracle\oradata\<dbname> - it is primary database dafiles location
D:\oradata\<standbydbuniquename> - it is standby database datafile location.
Don't forget creation of diagnostinc dests.

Configuring & Managing Data Guard 11g R2 with OEM 11g

Hi All,
Please let me know how to configure OEM for already setup standby database in Enterprise Manager

Hello;
So you did not Reinstate correct? Please understand it is very difficult to help you when you don't answer the questions.
My failover test notes are here :
http://www.visi.com/~mseberg/Data_Guard_Failover_Test_using_SQL.pdf
Oracle support has an excellent note :
Step by Step Guide on How To Reinstate Failed Primary Database into Physical Standby [ID 738642.1]
Feedback is critical when you ask a question. I searched and found this :

10g Data Guard Install Questions... Solaris 9

Firstly, I've done several Failsafe installes on Wintel platforms, but I'm having a tough time getting started installing Dataguard on Solaris. According to the manual:
Oracle® Data Guard Broker
10g Release 1 (10.1)
Part Number B10822-01
"The Oracle Data Guard graphical user interface (GUI), which you can use to manage broker configurations, is installed with the Oracle Enterprise Manager software."
I don't see any link or otherwise access to Data Guard via the 10g Enterprise Manager. Is there something that I missed during install that will allow me access Data Guard GUI?
I'm stuck

Data Guard Configuration Issue / ORA-16047

So last night I decided to setup a test Physical Standby database. I had everything working correctly and when I started playing around with the Data Guard Broker I started having some problems. Now I can't get the logs to ship from the primary to the standby.

Cause:       The DB_UNIQUE_NAME specified for the destination does not match the DB_UNIQUE_NAME at the destination.
Action:     Make sure the DB_UNIQUE_NAME specified in the LOG_ARCHIVE_DEST_n parameter defined for the destination matches the DB_UNIQUE_NAME parameter defined at the destination.As you can see from above the DB_UNIQUE_NAME in the LOG_ARCHIVE_DEST_2 parameter matches that of the standby database.
Also DG_BROKER_START is set to false on both the primary and standby databases.
Finally, I've removed all the drc* files from the $ORACLE_HOME/dbs directories on both the primary and standby servers to ensure the broker is not configured.
Where did I go wrong? How can I get the standby caught up and working correctly again?
I apologized if I missed anything. I'm relatively new to standby databases.

Centinul;
I have noticed a couple things
1. If you are running the query below from the standby you will probably always get the results you posted
SELECT sequence#, applied from v$archived_log order by sequence#;
What I do if run this from the primary and I add the "DEST_ID" column to the query.
2. You might have better luck finding GAPS using these queries:
select max(sequence#) from v$archived_log where applied='YES';
select process,status from v$managed_standby;
SELECT * FROM V$ARCHIVE_GAP;
3. You are mixing SQL results with Data Broker, that can bite you. Not sure where you went wrong but I would create PFILE versions at both ends before trying to Data Broker. The you can review each setting and avoid issues before adding Data Broker. Data Broker will take control and you may even find it adds entries to your parameter file.
The ORA-16047 is probably database parameter related and this should at least help answer the question. For example you might be missing log_archive_config on the Standby or soething. Comparing the two PFILE's should narrow this down
I checked my Data Broker notes but did not find an ORA-16047, I managed ORA-01031, ORA-16675, ORA-12514, and ORA-16608.
For me I decided it was a good idea to run Data Guard without Data Broker at first until I got the feel of it using SQL.
Last of all if you have not already consider buying Larry Carpenter's "Oracle Data Guard 11g Handbook" In my humble opinion its worth every penny and more.

Init SID .ora during configuration of Data Guard - advice required

Hi All,
I am looking to implement data guard across 2 RAC clusters. One cluster will be primary and the other is for Disaster Recovery.
I have already set up the two 11g R 2 RAC clusters on RHEL 5 and now need some pointers to good docs for data guard install.
Can some one direct me to good step by step info for configuring data guard between to RAC clusters - detailed explanations of each step would be useful too, in particular around the init.ora file configuration changes between the primary and DR sites
Much appreciated
Steve

Hi Steve,
look at the MAA Whitepapers:
http://www.oracle.com/technetwork/database/features/availability/oracle-database-maa-best-practices-155386.html
There are very good ressources in setting up RAC DG environments like:

Data Guard parameter

HI There
I have recently configure Data guard with Database 10g (10.2.0.4-64 bits) on Windows 2007 server.
My Data Gurad Configuration show Success status with 2 databases on same (or local) location.
My questions are
1-When I query SHOW PARAMETER LOG ARCH
DG_CONFIG(PRMDB)
ONLY 1 (PRIMARY DATABASE IS DISPLAYED ONLY NOT 2 DTATABASES
e.g. DG_CONFIG(PRMDB, STLDB)
2- How to check the log applied interval or time (either transaction by transaction, timing etc)
Kind Regards

NO.

Active data guard 11gr2

hi,
I want to setup Active Data Guard Oracle 11gr2. This is my first time. Is there any good guide or cookbook for setting up active data guard 11g. I want to setup on linux. I'll be thankful.
thanx

There's not so much to configure, it's only a sequence of statements:
http://download.oracle.com/docs/cd/E11882_01/server.112/e22491/manage_ps.htm#sthref597
More important - not technical - point is you need an extra licence.
In fact Real-Time Query means Active DataGuard.

Oracle 11g Active Data Guard是怎么收费的?

原来在Oracle 10g中，DG是免费使用的，想请问一下，在Oracle 11g中，性能得到加强的ADG是怎么收费的？谢谢

FYI
Use customary EE Option License Practices
Active Data Guard license required if using either Real-time Query or RMAN block-change tracking on a standby
Example with primary and 5 separate standby databases
S1 = physical - real-time query
S2 = physical - real-time query + RMAN block change tracking
S3 = physical - RMAN block change tracking
S4 = physical - neither real-time query nor RMAN block change tracking
S5 = logical
Active Data Guard must be licensed for primary and for S1, S2 and S3.
Active Data Guard is not relevant to logical standby

Does Oracle 10g support Active Data-guard?

Hi all,
Can Oracle Database 10g support Active Data-guard?
Thanks you!
Dan
Edited by: Dan on Jul 12, 2011 10:13 AM

no, active data guard is 11gR1 new feature.
In Oracle Database 10g and below you could open the physical standby database for read-only activities (say, to offload some reporting), but only after stopping the recovery process. With these releases, If Data Guard is a part of your DR solution, you really can't afford to pause the recovery process for a long duration for fear of falling behind, so the physical standby database is essentially useless for any read-only activity.
With Oracle Database 11g, that situation changes: You can open the physical standby database in read-only mode and restart the recovery process. This means you can continue to be in sync with primary but can use the standby for reporting. (As in previous versions, you can take the backup from the standby as well.)
