Data Guard Script

Hi,
I would like to know how to write a batch file in windows for dataguard environment.
For Example.
I woud like to write a batch file to show me the help command.
c:\dgmgrl
help alter;
How do you put these two statements in the batch file in windows? Your help is highly apprecicated.
Thanks,
Howie Ho

Can someone please help me with this? I need to automate the process to change the standby to read-only at midnight so I dont have to get up everyday at midnight at change the database to read-only mode. I can accomplish via sqlplus, but it's not recommended in the dataguard environment.
Thanks,
Howie ho

Hi Guys,
I am looking for a shell script that i can cron ,which monitors dataguard env (10g and 11g )and sent email alerts if DR go out of sync say by 10 or 15 logs
i found couple on the net but not working for some reason
http://emrebaransel.blogspot.com/2009/07/shell-script-to-check-dataguard-status.html
if you guys have some please share

You are using an advanced version of Oracle and want to plug an obsolete script into it??
Why not just monitor the Data Guard with EM or Grid Control and setup emails in there? It is 100% more reliable than anything else.

Shell script to monitor the data guard

Hi,
Can any body please provide the shell scripts to monitor the data guard in all scenarios and to get the mail when problem occurs in dataguard.
Thanks,
Mahipal

Sorry Mahi. Looks like all of the scripts i've got are for logical standbys and not physical. Have a look at the link ualual posted - easy enough to knock up a script from one or more of those data dictionary views. Just had a look on metalink and there's what looks to be a good script in note 241438.1. Its a good starting point definately.

Data Guard Agent, Authentication Failure

I'm working with two Windows 2003 servers, attempting to use one as a standby and one as a primary database use Data Guard. However, I'm having a bit of trouble when trying to get one server to communicate through the Management Agent and Management Service. I've done Management Agent installs on about 20 XP workstations and they've also worked wonderfully with the Oracle Grid Control.
When the agent on my would-be standby database instance starts up I'm receiving the following errors in emagent.trc:

I've already toggled the Local Security Policy (Log On As Batch Job) setting in Windows, unlocked the Monitoring Profile account, etc. I've also tried to set the Preferred Host Credentials for the database, but it doesn't seem to want to authenticate the Windows 2003 Administrator user.
Anyone have any other suggestions?

Check the following:
Does the user have administrative privilege on the system?
Is the user running this part of ORA_DBA group?
Does the user have the local security policy "Logon as Batch Job"?
Have you set the OS Preferred Credential? If you are a domain user, this will be looking for domain\user name instead of just the user name.
On another note:
Have you doen any upgrades to the OMS repository?
If yes, is the new Repository compatible with the EM Console?

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

Regarding data guard

hi..has anyone wrote a cron shell script to shutdown, start in mount mode, flash on, enable managed recovery..etc..for data guard..something generic i can start with..thanks

Hi,
I dont have an script but you can do it from Grid control.

Data guard standby restart in rocover mode

Hi,
I inherited a data guard database and found that the secondary DB has been out of sync with primary. I perform SCN recovery to the secondary and now they are fine syncing. I figured I had to manually put the standby in recover mode after open in read only mode in the one I worked on which is our qual environment where as it is not like that in the prod. Can anyone advise what I need to do to have this standby in recovery mode even after the DB go down for maintenance and come back on?
Thanks for your input,
fakord

Hi,
If you are using database guard broker then it will automatically starts the apply as it controls the apply. If not probably a shell script to start the standby database followed by this line can help.

Oracle EBS R12 - DR setup using Oracle Data Guard

Hi,
Our customer has implemented Oracle EBS R12 (12.0.6) on a Two Node RAC on HP-UX env. The application Tier also has Two Nodes(Admin Tier and Web Tier).
Oracle Clusterware - OCR and Vote Disk are on Raw Devices and the EBS database is on ASM.
Customer wants to implement a DR solution with Oracle Data Guard with only 2 servers - 1 for the Database Tier and 1 for the Application Tier on the DR Site.
I would like to know if this could be done by following note: 452056.1? I would also like to know if there are other useful docs.
Thanks.
Thiru

Hi,
Customer escalated this issue to Oracle and they came up with this reply:
They can implement Disaster recovery solution from RAC to NON RAC using Solution A which use RMAN utilities for backup and recovery.
While now AMP Application Management Pack gives the capablitiy to build non RAC from RAC Envioment, In future AMP will be capable also to support cloning of DB with Data Guard.
Details
Solution A - Using RMAN:
For Release 12 customers, you can clone from a RAC to RAC (like to like) or RAC to non-RAC. This is using RMAN scripts to take a copy of the db when it’s in archive mode. if you’re leveraging any disaster recovery tools like data guard, the above solution should work fine…perhaps some fine tuning to the procedures
Solution B - Using AMP in the future release
For Release 11i , Release 12.x customers, AMP would be offering a new cloning solution that wouldn’t have dependency on Rapid Clone. This solution leverages the strengths of EM Grid Control in provisioning or cloning targets such as databases. This would be an advance solution that would support:
o A full-fledged scale down cloning
o Cloning of EBS deployed on Shared File System
o Hot and Cold mode cloning
o Quantifiable reduction in clone time for the entire EBS system
This solution would be leveraging EM grid Control’s DB provisioning pack’s clone utilities, that are quite advanced and support cloning of DB with Data Guard.
The recommendation is to start trialing AMP version 3.0, making the purchase and implementing within the Enterprise. As we release the new version of AMP (release 3.0.1), Customer would be in a better position to quickly implement the latest features
Can anyone let me know if the solution A suggested will work.
Rgds,
Thiru

Cloning a database from data guard

Hi Gurus,
I have a situation where I am using 11g R1 11.1.0.7
Primary database in server prodsrv and active data guard read only db in drsrv host.
I have to clone a new dev database in drsrv database. since 11g R1 supports clone from active database, i thought we can use active data guard to clone a new database.
is that possible? my trial didn't work out.

Oracle data guard configuration for primary and standby db_name

I am working on configuring an active data guard for one primary DB and one standby DB. I have a few questions:
1. Can I use different db_name, db_unique_name and instance_name for primary and standby. For example: primary(db_name, db_unique_name and instance_name)=chicago. When I create standby DB with Rman backup and copy of pfile and control file from primary DB or use Grid control to create standby database. Oracle document or Grid control all keep standby db_name=chicago. Only make standby db_unique_name and instance_name=boston. Due to my application system condition, I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?
2. In primary datafiles, application system generate datafile name like this: hr_chicago_01.dbf, fn_chicago_01.dbf. When I move datafiles to standby server, if I plan to use db_name=boston for standby DB, can I rename datafiles as
hr_boston_01.dbf, fn_boston_01.dbf? In this way, datafile name match up with db_name. but I will create standby log group and members on primary and standby identically. If in future switching over, DB will not have problems.
3. If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standby. Then "alter database backup controlfile to trace" from promary and also " create pfile='/xxx/initSTANDBY.ora' from primary. Then modify init.ora and controlfile. Then run control.sql to bring standby DB up. After that, configure redo log shipping and apply with data guard or SQL. Is this a acceptable way to create physical standby DB?
Please advise your comments. Thanks in advance.

I want to make db_name=boston, not keep it as the same as primary=chicago. Is this valid configuration?NO. DB_NAME must be the same ("chicago") at both sites. The Standby will be using a different DB_UNIQUE_NAME (e.g. "boston") and can be using a different Instance name / SID (e.g. "boston").
can I rename datafiles Yes. The database file names can be changed.
If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standbyWhat is the difference between the first sentence (a backup of the primary) and the second sentence (a copy of the primary) ? A Copy is a backup.
Are you intending to differentiate between an RMAN Backup and a User-Managed (aka "scripted") backup ?
Normally, for DataGuard, tou can use non-RMAN methods to copy the database but there's no value add in this.
You'd still have to setup DataGuard ! (and I wonder if you'd have complications setting up Active DataGuard).
But remember that you MUST create the Standby controlfile from the Primary and copy it over to your Standby -- particularly as you are planning to use DataGuard. This is not created by 'alter database backup controlfile to trace' , but by 'ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'filename''

Oracle9i Data Guard - Filtering for a Logical Standby DB?

Hello All
1) When using Oracle9i data guard with a logical standby database is it possible to "screen" the sql statements that are executed? For example if I don't want any "delete" commands to be replicated on the standby box can I filter them out?.
2) Are there any unlogged transactions that don't get "replicated"? Can I get a list of these commands/transactions?
Any insight would be greatly appreciated
Thanks in advance

can I rename datafiles Yes. The database file names can be changed.
If I don't use primary DB backup. Instead, I copy all datafiles, redo_log files (no control files) to standbyWhat is the difference between the first sentence (a backup of the primary) and the second sentence (a copy of the primary) ? A Copy is a backup.
Are you intending to differentiate between an RMAN Backup and a User-Managed (aka "scripted") backup ?
Normally, for DataGuard, tou can use non-RMAN methods to copy the database but there's no value add in this.
You'd still have to setup DataGuard ! (and I wonder if you'd have complications setting up Active DataGuard).
But remember that you MUST create the Standby controlfile from the Primary and copy it over to your Standby -- particularly as you are planning to use DataGuard. This is not created by 'alter database backup controlfile to trace' , but by 'ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'filename''
