The answer depends on the protection level are you using, If you are using maximum performance or maximum availability you can use 6 groups with 1 member in each group, in case of redo corruption the primary database will continue to function properly and you will have time to fix the corrupted redo. If you are planning to use maximum protection I would recommend at least 2 members in each group, to avoid primary crush in case of standby redo corruption.

11g Data Guard --ORA-01103: database name 'PRIM' in control file is not 'ST

Dear all,
From no mount stage i am trying to bring the db in mount stage in standby database
SQL> alter database mount standby database;
alter database mount standby database
ERROR at line 1:
ORA-01103: database name 'PRIM' in control file is not 'STANDBY'
What is this problem ?
I have taken standby control from from standby database and places with datafile's and removed the orginal control file. and added this standby.ora file in parameter file also (pfile).
the Primary database name is PRIM and standby database name is STANDBY.
This is my first time doing this data guard configuration kindly let me know what i have to do at this above mentioned stage ..
Regards
Hamid

Steps i have followed till now.
1) Created standby control file in primary in mount stage (STANDBY.CTL)
2) Installed 11g DB software alone in standby location
3) Shutdown the Primary DB and Taken cold back of all the other files and copied in Standby DB location (Primary in D:\ Drive and Standby in F:\ Drive )
4) Edited init parameters in Primary and standby
5) Startup no mount pfile= standby db init file ( its started )
6) SQL> alter database mount standby database; --- at this time i got the error i have mentioned above, so i have changed the db_name same in both init.ora files
7)
Up to this step i have done .. but this is all blindly.. not in clear understanding..
Kindly guide me.. step by step configuration..

因为是实验用库，所以结构有点怪，大体如下:
Primary
数据文件在BASE所在的oradata下即/u03/app/oracle下,
redo文件每组两份，一份在oradata下，另一份在同机的/u04/app/oracle/redundancy中（以_s结尾命名）
archive文件在/u04/app/oracle/fast_recovery_area中
standby
数据文件在/u05/oracle/app/oracle/oradata下
redundancy中的redo文件随着该目录放到oradata下的red中了
archive文件目录则是/u05/oracle/app/oracle/fast_recovery_area中
接下来是对应的init文件与TNS信息

PS：请大家花费一点点时间阅读一下这冗长的段子，刚开学data guard，参数上设置都很生疏，（光照着文档做了，是否有redo log相关的操作遗漏？）敬请指教

Install Guide of Active Data Guard for 11g R2 on Linux

Friends,
Searched for this on tahiti.oracle.com which redirects you to the oracle's docs.
Anyone knowing where to find installation guide for active data guard of 11g R2 on linux?
Thanks much.

This article looks useful
http://dbastreet.com/blog/?p=16
Also you may want to check Larry's book on 11g Data Guard. It has a complete chapter on Active Data Guard.

Data Guard broker compatiblity

Hi All,
I have environment where we are running following version of databases
1- Oracle 9.2.0.6
2- Oracle 10.2.0.1
3- Oracle 10.2.0.2
4- Oracle 10.2.0.3
5- Oracle 10.2.0.4
6- Catalog DB 11.2.0
My question is whether 10g/11g data guard will support these databases?
Thanks in advance.

The dataguard broker (basically that is the DMON background process) is always from the same version as the database.
Maybe you confuse Grid Control with the dataguard broker. Indeed can a higher versions Grid Control maintain lower versions databases.
It may also setup & maintain Data Guard for these lower versions databases.
Kind regards

Oracle 11g Data Gaurd problem

I am currently in a Dev environment, working on a 11g Data Guard configuration, having Primary and Standby in 2 different nodes.
Both the nodes had their parameter files configured with the specific DG parameters, which are as below -
Primary init.ora
*.db_domain=''
*.db_name='o11_prim'
*.db_unique_name='o11_prim'
*.instance_name='o11_prim'

Initially, the Archive logs were getting transferred to the Standby via Automatic Managed Recovery Process. Command given below.
# This command is being run on Standby for starting Automatic Managed
# Recovery Process
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
Then we used to tail the Alert logs of both Primary and Standby, and the logs got transferred at the physical location of the Archive logs in Standby db.
Then one day due to some problem with the pfile, I shutdown the Standby db with the Primary up and running as usual using the following command-
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL IMMEDIATE;
The Result was as expected - Primary Archive logs got accumulated and the same couldn't be transferred to Standby as the Standby was down.
I had to manually recover the Standby by copying the extra Archive log files from Primary to Standby and then running the Recovery Process manually, using the below command -
SQL> RECOVER AUTOMATIC STANDBY DATABASE
Then when I restarted the Automatic Recovery process on Standby, I received the error as below -
ORA-16009 - Remote archive log destination must be a STANDBY database
This error keeps appearing on the alert log of both primary and physical standby that i configured.
I have no clue as to where it went wrong.
Kindly help!

There is no one drowning.
Your house is not on fire.
The volcano has not exploded.
Please apologize for abusing this forum by claiming your issue is more urgent than other people's requests.
Then, and only then, should anyone help you. I know I certainly won't until I read your sincere apology and promise not to be abusive in the future.

11g Active Data Guard Software?

I got a copy of the 11g (for SUN SPARC) from the edelivery.com, and got the patch for 11.1.0.7 from metalink.
I upgraded 110.2.0.4 to 11.1.0.7. But, I could not get the ADG to work.
Here is what happened when I queried the database status.
--------------------------- begin ---------------------------------
SQL> alter database recover managed standby database cancel;
Database altered.
SQL> alter database open;
Database altered.
SQL> select status from v$instance
2 ;
STATUS
OPEN
SQL> select OPEN_MODE from v$database;
OPEN_MODE
READ ONLY
SQL> alter database recover managed standby database using current logfile disconnect;
Database altered.
SQL> select OPEN_MODE from v$database;
OPEN_MODE
MOUNTED
SQL> select status from v$instance;
STATUS
MOUNTED
---------------------------- end ------------------------------------
Turning on the Redo Apply put the database mode back to 'MOUNTED'. For ADG, it should remain 'OPEN'. I suspect this copy of 11g does not have the ADG feature.
Is there a way I could check whether the ADG is installed? Is there a directory under $ORACLE_HOME or a script under $ORACLE_HOME/rdbms/admin that indicates the ADG is indeed installed?
Where did you guys get your software?
Thanks very much in advance.

You should have the right software and the right option installations in Entreprise Edition (otherwise Data Guard would not work at all).
Did you check both alert log for possible error messages ?
I think you should open the database in read-only mode instead of read-write mode:
alter database open read only;See following OTN example: http://www.oracle.com/technology/pub/articles/oracle-database-11g-top-features/11g-dataguard.html

Oracle 11g Active Data Guard help ?

Hi Friends,
I successfully setup an Active data guard environment(11g). But, I dont know when the PROD database is highly utilize , its read only tasks like reporting and backup are doing in STANDBY. How can I know which db (prod or stand by) is used for these readonly operations ?
Regards

It is not so simple to direct reports to the Physical Standby as you seem to assume.
You need to do some work for the setup.

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

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
