Configuring a physical standby database in 9i
Hi all,
SO: Solaris 10 SPARC x64
DB: 9.2.0.6 x64
I have a task of creating a physical standby database in a solaris 10 - Oracle 9.2.0.6 env. I am used to do this configuration on the 11.2 version of Oracle, and because of that i have some doubts regarding the possible different configurations necessary to do in a 9i Database.
1) The main doubt that i have is regarding the RMAN use. I Would like to know if it is possible to restore a normal backup of my primary database into the standby database, and after that, apply the necessary archived logs to sync the standby with the primary? The controlfile that i would use would be the one created by the "BACKUP CURRENT CONTROLFILE FOR STANDBY" RMAN command. The RMAN script woulb be like the one below:
run {
allocate channel ch01 device type disk;
allocate channel ch02 device type disk;
allocate channel ch03 device type disk;
allocate channel ch04 device type disk;
restore controlfile from 'standby_controlfile.ctl';
sql 'alter database mount';
restore database;
recover database;
2) The directory structure will be the same, so i think it is not necessary to use the SET NEWNAME and the DB_FILE_NAME_CONVERT/LOG_FILE_NAME_CONVERT, is that correct?
3) Do you have any other considerations regarting the differences between a 9i and a 11g Physical Standby Configuration?
Thanks for your attention and pacience.
Hello;
On question 1 - See this:
http://docs.oracle.com/cd/B10500_01/server.920/a96566/rcmstand.htm
On question 2 - Assuming RMAN work then DB_FILE_NAME_CONVERT/LOG_FILE_NAME_CONVERT would NOT have to be set for the same directory structure.
On question 3 - double check this:
http://docs.oracle.com/cd/B10500_01/server.920/a96653.pdf

Physical Standby Database (Protection Mode)?!!
Hi,
I have configured a physical standby database to use Real-time Apply, but i noticed that the protection mode of the database has been changed from "Maximum Performance" to ''Maximum Availability"..
log_archive_dest_3='service=phystby OPTIONAL LGWR SYNC AFFIRM reopen=120 valid_for=(online_logfiles,primary_role) db_unique_name=phystby'
Any body to explaine??
Regards,LGWR SYNC AFFIRM
These are the options are used in maximum protection mode ,in which oracle will write the information in both the server(primary and standby) and this write occurs at same time.
oracle write the information in online redo logfile of both the server simultaneously.
and this option ensure no data loss will occurs if primary will fail.
SYNC related with Network transmission mode.
AFFIRM related with disk write option.
LGWR describe Redo archival process.
Thanks

Clarification on creating a Physical Standby Database
I'm practicing with data guard with Oracle 10.2.0.1.0 on two Windows 2003 servers.
I'm in the process of creating a physical standby database by following the steps outlined in the guide http://www.filibeto.org/sun/lib/nonsun/oracle/10.2.0.1.0/B19306_01/server.102/b14239/create_ps.htm
I've created the primary database and did a cold backup of all the datafiles and copied them to the standby server using OS commands. I've created a pfile from the spile in primary database and changed the needed parameters for the standby database.
What I don't understand is this statement I think is creating a control file for the standby database: SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tamp/standby.ctl'
Exactly what I don't understand is what to do with this control file. I'm thinking that if I try to use it as the controlfile for the standby database, the standby database will refuse to open since the database name in the control file wont match the one the server expects.
I don't want to proceed until this becomes clear. So my question is what to do with the output of the above statement that seems to create a control file for the standby database.
Any help would be appreciated.
Dula>
You're thinking wrong.
Please clarify the difference between db_name and
db_unique_name.
Db_unique_name needs to be identical for both primary
AND standby database.
If db_unique_name differs, you'll get errors.
Sybrand,
Perhaps, you meant DB_NAME has to be identical for both databases.
DB_NAME name has to be the same for both primary and physical standby database.
DB_UNIQUE_NAME should be unique for each database in the standby configuration.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i68626
If you configure Logical Standby Database, DB_NAME may be different.
For the original poster: Chapter 3 - Creating a Physical Standby Database of Oracle® Data Guard Concepts and Administration has all the steps you have to do in order to configure a physical standby database.

Oracle Configuration Manager 10.2.7 on physical standby database
Hi
Did anybody succeed to install and get running OCM on physical standby-database? When starting collection configuration script, i get
an known error ORA-01219.
Any help any tipps?
FeliceHi Tom
Thank you for the information. I think it is the right place to install OCM - not standalone installation - software installed with Oracle Database Enterprise Edition. The problem is only that installCCRSQL.sh can't handle Mounted Database (Standby-Database).
We got similar problems with Grid Control Management Agents, when doing health checks.
Mayby there is as workaround/patch (Opatch).

Error while creating physical standby database using Oracle Grid 10.2.0.5
Hi All,
I am setting up data guard using oracle grid.

Can anyone suggest what could be the reason behind this?Dear user13295317,
Here is the error explanation;
Oracle Error :: TNS-12533
TNS:illegal ADDRESS parameters
Cause
An illegal set of protocol adapter parameters was specified.
In some cases, this error is returned when a connection cannot be made to the protocol transport.
Action
Verify that the destination can be reached using the specified protocol.
Check the parameters within the ADDRESS section of TNSNAMES.ORA.
Legal ADDRESS parameter formats may be found in the Oracle operating system specific documentation for your platform.
Protocols that resolve names at the transport layer (such as DECnet object names) are vulnerable to this error if not properly configured or names are misspelled.Hope That Helps.

Starting Physically Standby Database in Mount Mode
Hi All
I have configured Data Guard using Oracle 10g 10.2.0.4.0 (64 bits) on Windows 2008 Server (64 bits) Release 2 Enterprise.
Data guard configuration was OK as the message from "Enable Configuration DG1" was "SUCCESS" for both
Primary and Standby Database. I have also set both Databases and TNS to start Automatically whenever Windows Starts.
The Problem is as long as the Standby Server is running, there is No issue.
But when we Restarts the Backup Server, Physically Standby Database is Started and TNS is also Started,
but Archives are not received until I physically do the following steps so that it can received the Archives.
SQL> startup nomount;
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect from session;
Is there a way to start Physically Standby Database in Mount mode when windows started.
Regards

Physical standby database in RAC system
Hi EXperts,
We have a 4 nodes 11.2 cluster system. i will set a data guard as a disaster recovery mothods.
As a physical standby database set, does we need to configure same nodes (4 nodes) in other city as primary database cluster system?
Can we set physical standby database is in 2 nodes cluster system and primary database is in 4 nodes cluster system?
Thanks explaining!
JinCan we set physical standby database is in 2 nodes cluster system and primary database is in 4 nodes cluster system?Yes. You can setup 2 node RAC as physical standby and also with different memory parameters. But, the only issue is when DB failover from primary to standby, the applications connect to 2 node RAC in place of 4 node RAC and may be overloaded.

Physical standby database implementation
Hi!
I am trying to implement a Physical standby database, I have already done it with both the primary and secondary in the same server and successfully shipped the logs and have it configured using Data Guard.
But Now I am trying to implement the Physical standby in a separate server, but the logs are not getting shipped, I am using Oracle 9i Enterprise edition. I have checked all the steps, but not able to find the reason, why the logs are not getting shipped to the standby.
Also I am not able to discover the Primary node from the Standby and I have Windows 2003 server in my standby and Windows XP Prof. in the Primary, Is this the reason, why my logs are not getting shipped?
Please help. Thanks in Advance.
RadhikaHi!,
Thanks for ur response, I am posting my alert log here... can u please help me... I probably think it is the OS issue too... Your inputs are greatly appreciated...
Thanks

Questions regarding creating a physical standby database in 10gR2
I'm setting up a physical standby database in a test environment using two windows 2003 servers. I was wondering if someone could answer a few questions I'm not too clear on. I've been thru the data guard manual and as much online information as i can find. I may have it working but wanted to post some things I'm not sure I did quite right.
My tnsnames.ora files.
On my primary database server:
# tnsnames.ora Network Configuration File: F:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
PRIMARY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = SERVER1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRIMARY.MYDOMAIN.com)
STANDBY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = SERVER2)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = STANDBY.MYDOMAIN.com)
On my physical standby database server:
# tnsnames.ora Network Configuration File: f:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
STANDBY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = SERVER2)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = STANDBY.MYDOMAIN.com)

(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = SERVER1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRIMARY.MYDOMAIN.com)
My Listener.ora files:
On my primary database server:
# listener.ora Network Configuration File: F:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = PRIMARY.MYDOMAIN.com)
(ORACLE_HOME = f:\oracle\product\10.2.0\db_1)
(SID_NAME = primary)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = server1.mydomain.com)(PORT = 1521))
On my physical standby database server:
# listener.ora Network Configuration File: f:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = standby.mydomain.com)
(ORACLE_HOME = f:\oracle\product\10.2.0\db_1)
(SID_NAME = standby)
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = sever2.mydomain.com)(PORT = 1521))
The next item I'm not sure about is after creating the control file for standby use.
One the primary server I created it using:
alter database create standby controlfile as 'sbcontrol01.ctl';
I copied the primary database pfile I had created earlier to the standby server, renamed it and edited it.
Initially I left the CONTROL_FILES= parameter pointing to the control01.ctl, control02.ctl and control03.ctl that I restored. But I was getting the error ORA-01665: control file is not a standby control file
So I copied the sbcontrol01.ctl to sbcontrol02 and sbcontrol03.ctl and pointed the CONTROL_FILES= parameter at them.
The error went away and the database came up. I still need to test it some more but wanted to see if what i did was correct or a fluke.
Edited by: tjohnson on Mar 23, 2009 2:26 PMIf in the primary I had control files named control01, control02 and control03 would I have been able to create a standby controlfile called control01.ctl or would I have had to name it something else like I did (sbcontrol01.ctl) and rename it to control01.ctl once I got it over to the standby database server?Suppose you have the primary database control file in C:\oracle\primary\control location with names control01.ctl and control02.ctl. Then also you can create a standby controlfile with control01.ctl and control02.ctl , but then the location to be created must be different.You can create it in C:\oracle\primary location and then transfer to the specified location mentioed in the pfile of the standby database and mount the standby database.
But saying this i would suggested to keep the name different from control01.ctl as far as naming conventions are followed.It might confuse someoe whether its a primary database controlfe or a standby database controlfile.Usally primary database controlfile are named control01.ctl , coltrol02.ctl etc and for standby many do prefer keeping standby01.ctl, standby02.ctl.Thats just for for understanding.

Firstly you can use "*select sequence#,first_time,next_time from v$archived_log order by sequence#;"* command in mount stage itself.No need to open the standby database in ready only mode.
No rows selected in mount stage also.
The V$ARCHIVED_LOG fixed view on the physical standby database shows all the archived redo log files received from the primary database.
sql> select * from v$archived_log;
no rows selected.
and No archived logs received from primary database to physical standby . i think here i wrongly configure parameter file.

When you do log switch on the primary are the archive logs getting transferred to the standby database???Is there some error in the alert log file in the primary database.
No..

More than One Physical Standby Database
Hi All!
Is it possible to have more than one physical standby database? Does the procedure on how to create a single physical standby is the same as creating more than one? How about the configuration of the Primary database? Im planning this because I want the other physical standby to be used for read only access for our testing environment.
Please enlighten me.
Regards,
cmadiamThink about it.
Q. What's the crux of Dataguard setup?
A. Redo transfer from primary to standby
Q.Which is the parameter you use to direct the redo transfer
A. LOG_ARCHIVE_DEST_n
Q. How many LOG_ARCHIVE_DEST_n parameters can be set?
A. 10; LOG_ARCHIVE_DEST_1 to LOG_ARCHIVE_DEST_10
Of the 10 LOG_ARCHIVE_DEST_n, one of them should be LOCAL destination, which means you can have 9 other REMOTE destinations ~~ 9 standby database. Physical or logical or mix of both.
Cheers.
Note: Each of the 9 standby database can cascade redo transfer to 9 other cascaded standby databases. WOW! now you do the math. -
Physical Standby Database with slight complication
Hello Database experts,
Primary is a multi-node RAC instance , primarily two distinct schemas (for simplicity sake schema A on tablespace A1/A2 and schema B on tablespace B1/B2). There is a proposed physical standby database. Now primary is Enterprise Data warehouse with millions of updates per minute. Is it possible to somehow bypass objects owned by schema A to be propogated on DR instance.
Any workaround possible?
Assume that Hot backup of primary database backup has to be done so we can not perform nologging operations on schema A and Logical standby is not a option.
Kind Regards,
Sunil***Is it possible to somehow bypass objects owned by schema A to be propogated on DR instance.***
Yes. but not in physical standby. While bypassing the objects to physical standby the recovery cannot be enabled at the time. So data loss may occur. Try to configure logical standby database. you can get what you expect.

Cannot Clear Critical Alert for Physical Standby Databases
10.2.0.4.0 Grid Control monitoring 10.2.0.4.0 databases and standby databases with 10.2.0.4.0 agents.
The standby databases are running on Xen guests. The O/S is Red Hat 4 Advanced Server.
I had a failure of Xen guest on Saturday that caused me to have to rebuild the standby servers. EM Grid Control successfully verifies the configurations and the status is normal for both physical standby databases. (A rebuilt logical standby database shows no alerts.)
Grid Control database targets page shows a single critical alert for each physical standby database. The alert is for "number of missing media files is 4". The metric graph shows the count as 0 since before the rebuilds. I cannot clear the alerts from the Critical Alerts page. Grid Control reports "The selected alert(s) cannot be manually cleared. They will clear automatically once the metric is no longer in a critical or warning state.".
Any suggestions?
Thanks,
Ray WestphalThanks for the reply Anthony.
The result of the query on both standby databases is '0'. The metric graph also shows the value at '0' since before rebuilds.
And the OMS db and agents have been reset several times since I posted this.

Physical standby database fail-over
Hi,
I am working on Oracle 10.2.0.3 on Solaris SPARC 64-bit.
I have a Dataguard configuration with a single Physical standby database that uses real time application. We had a major application upgrade yesterday and before the start of upgrade, we cancelled the media recovery and disabled the log_archive_dest_n so that it doesn't ship the archive logs to standby site. We left the dataguard configuration in this mode incase of a rollback.
Primary:
alter system set log_archive_dest_state_2='DEFER';
alter system switch logfile;
Standby:
alter database recover managed standby database cancel;Due to application upgrade induced problems we had to failover to the physical standby, which was not in sync with primary from yesterday. I used the following method to fail-over since i do not want to apply any redo from yesterday.
Standby:
alter database activate physical standby database;
alter database open;
shutdown immediate;
startupSo, after this step, the database was a stand alone database, which doesn't have any standby databases yet (but it still has log_archive_config parameter set and log_archive_dest_n parameters set but i have 'DEFER' the log_archive_dest_n pointing to the old primary). I have even changed the "archive log deletion policy to NONE"
RMAN> configure archivelog deletion policy to none;After the fail-over was completed, the log sequence started from Sequence 1. We cleared the FRA to make space for the new archive logs and started off a FULL database backup (backup incremental level 0 database plus archivelog delete input). The backup succeded but we got these alerts in the backup log that RMAN cannot delete the archivelogs.
RMAN-08137: WARNING: archive log not deleted as it is still neededMy question here is
1) Even though i have disabled the log_archive_dest_n parameters, why is RMAN not able to delete the archivelogs after backup when there is no standby database for this failed-over database?
2) Are all the old backups marked unusable after a fail-over is performed?
FYI... flashback database was not used in this case as it did not server our purpose.
Any information or documentation links would be greatly appreciated.
Thanks,
Harris.Thanks for the reply.
The FINISH FORCE works in some cases but if there is an archive gap (though it didn't report in our case), it might not work some times (DOCID: 846087.1). So, we followed the Switch-over & Fail-Over best practices where it mentioned about this "ACTIVE PHYSICAL STANDBY" for a fail-over if you intend not to apply any archivelogs. The process we followed is the Right one.
Anyhow, we got the issue resolved. Below is the resolution path.
1) Even though if you DEFER the LOG_ARCHIVE_DEST_STATE_N parameter's on the primary, there are some situations where the Primary database in a dataguard configuration where it will not delete the archive logs due to some SCN issues. This issue may or may not arise in all fail-over scenarios. If it does, then do the following checks
Follow DOCID: 803635.1, which talks about a PLSQL procedure to check for problematic SCN's in a dataguard configuration even though the physical standby databases are no available (i.e., if the dataguard parameters are set, log_archive_config, log_archive_dest_n='SERVICE=..." still set and even though corresponding LOG_ARCHIVE_DEST_STATE_N parameters are DEFERRED).
If this procedure returns any rows, then the primary database is not able to delete the archivelogs because it is still thinking there is a standby database and trying to save the archive logs because of the SCN conflict.
So, the best thing to do is, remove the DG related parameters from the spfile (log_archive_config, log_archive_dest_n parameters).
After i made these changes, i ran a test backup using "backup archivelog all delete input", the archive logs got deleted after backup without any issues.
Thanks,
Harris.
