Breaking DataGuard Configuration

Hi
We are in process of doing database upgrade in dataguard configuration and we are planning to break the dataguard configuration and we will do the upgrade in standby database then we will do it in primary. My questions here is
1)I am going to break the Dg configuration like disabling the DGBROKER,unset the archivelog dest,dg_broker_start=false.....so onnn
2)How to open the standby database in readwrite mode.
DB VERSION IS 9.2.0.6
os is WINDOWS-2000

Hi Ogan,
Can i do the following steps to break primary and standby.
1)DISABLE DATAGUARD BROKER CONFIGURATION
2)STOP MRP PROCESS ON STANDBY --->ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;---->
3) On the primary disable any archive destinations that are archiving to the standby:
SQL> select dest_id,destination,status from v$archive_dest where target=’STANDBY’;
SQL> alter system set log_archive_dest_state_2=defer scope=both;
4)on standby database mount standby database and issues the below command
ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
if i do like this is it going to work as primary???

Upgrade of database in Dataguard Configuration

Hi,
I have few doubts regarding upgrading of database in in a dataguard configuration. Could someone please help me out.
- How does upgrade happen in dataguard configuration?
- Is that we have to install only different OH in both? And once the catupgrade script is run on primary, it will automatically upgrade standby as well?
- Or is that we have to upgrade both separately? i.e, standby first and then primary or vice versa
- Can we reduce downtime by breaking the dataguard config. Do a switchover and make secondary as primary and upgrade primary first?
And once the upgrade is completed in primary, bring it up and later upgrade the standby. And later once the upgrade is completed on standby, synch both primary and standby.
Please share your ideas and thoughts!
Thanks!

First of all, -steps may differ regarding the upgrade versions but- my post with the following link would help you clarify the concept.

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,
Gianluca

yes, 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.

Database upgrade in a Dataguard Configuration - Help !

Hello Everyone,
I am upgrading our test Oracle 11G RAC/Dataguard Configuration from 11.1.0.6 to patchset 11.1.0.7 and have run into an issue when trying to apply the patchset to one of our standby databases.
I have upgraded our primary database to 11.1.0.7 with no problems, however when this was done the Dataguard Broker configuration was disabled and redo log apply to our standby databases (all physical) was stopped. I next attempted to upgrade one of our standby databases to 11.1.0.7, whilst DG Broker was disabled. The clusterware (all our databases are part of RAC clusters) and DB Software upgrades were OK, but I was unable to run DBUA successfully (or at all) as it wont run against the standby DB.
Looking at the process for applying upgrades with Physical Standby databases in place in the Dataguard Concepts manual, it seems as though the recommended process is that I should have upgraded the standby database(s) first rather than the primary database. The two Oracle Consultants that were on site when I upgraded the primary DB, did not seem to be aware of this !
What now is the easiest (and quickest) way of upgrading the standby db to 11.1.0.7 (preferably without reenabling the DG Broker Configuration). Is it possible to re-instanitate the standby DB from the primary DB?
Any advice would be much appreciated.
Thanks,
Shaun.

Hi!
Updating a standby DB must be so easy, but I suppose now you are in troubble because your primary DB is ...0.7 and standby are ...0.6, but in this situaction there isn't any problem. You only need to have same version at Oracle DBs (...0.7) and initiate the recovery process or start DataGuard Broker process (if you have all redo logs since the beggining of update process).
Chiao!

Multiple Standby Dataguard Configuration

Hi,
Sorry if this has been posted before, but I could not find the answer.
I have a Primary site (PRIM) and one Standby site(STBY1). The standby receives archive log changes from the primary. Also using dataguard to manage the Standby.
I would like to create another standby (STBY2) and use the current standby (STBY1) to send changes to the other standby (STBY2).
I've read the section on Cascade Redo Log Destinations in Section D of the Dataguard doc, but it really doesnt show how this is configured.
I assume that my standby (STBY1) would need a the log_archive_dest_2 set to the service that points to the second standby (STBY2).
My question is.. Do I need to be using Maximum Availibilty and send redo logs vice archive logs? How do I configure dataguard? Is the second standby (STBY2) another site in the dataguard configuration?
Thanks,
Roland

I'm curious, is there a reason that you wouldn't want PRIM to supply the changes to both STBY1 and STBY2? In the configuration you're describing, if there was a failure on STBY1, you couldn't fail over from PRIM to STBY2...

Install Grid Control and use repository within a DataGuard configuration

Hello,
I need some information if anyone has experience in the following
We have severel database running in DataGuard standby configuration.
I want to install OMS 11.1 and use the repository in a primary and standby configuration.
My configuration will look like this:
host 1     Primary Repository database
     OMS service 1
host 2     Standby Repository database
     OMS service 2
During normal operation i want to have 2 OMS services running.
Whenever a failover is necessary, i want to active my standby database and run OMS service 2.
Can this be a working configuration?
Any help is appreciated.
Regards,
Ben

Hi.
As far as I know, the dbconsole installed with the Oracle database applies for only one database on one server. The information accessed by the dbconsole relies within the sysman schema inside the actual database. For a database environment with 10 databases, it is possible to install grid control and manage all these databases despite version and OS. And I think that grid is a good solution to such an environment.
The grid installation itself is a application server installation, and I suggest if possible that you separate the rdbms server and the server that contains the grid control.
The repository database the grid control uses can either be installed in the 10g environment or in the grid control environment (server). You can place the repository in a new database in a separate ORACLE_HOME from the actual grid control application server.
Good luck.

SDU Dataguard configuration

Please,
Looking for some clarification implementing SDU parameter file.
I'm configuring Dataguard using Oracle 10g,Release 2 on Windows
In order to best use data size sent amoung primary,standby and clients application oracle recommends to configure SDU parameter for the highest size.
Network configuration.
Primary database
( [i]SQL net files mandatory: Listener,sqlnet.ora and tnsnames.ora)
Secondary database
(SQL net files mandatory: Listener,sqlnet.ora and tnsnames.ora)
Citrix server acting as client to the primary database
(SQL net files mandatory: sqlnet.ora and tnsnames.ora)
Users connect to the database through citrix
Communication between Primary and Secondary database
if I set the DEFAULT_SDU_SIZE=32767 on both primary and secondary database in SQLnet.ora file, I do not need to set this parameter either in tnsnames.ora nor listener.ora file on both primary and secondary database?
Communication between citrix client and primary database.
I should only set DEFAULT_SDU_SIZE=32767 into sqlnet.ora file for all connections involved.
My big trouble is, when reading the Oracle Maximum Availability Architecture White Paper February 2007 they recommend to:
specify on the primary database: DEFAULT_SDU_SIZE=32767 into sqlnet.ora file
On the standby database, set SDU in the SID_LIST of the listener.ora file: SID_LIST_listener_name=(SID_LIST= (SID_DESC= (SDU=32767) (GLOBAL_DBNAME=sales.us.acme.com) (SID_NAME=sales) (ORACLE_HOME=/usr/oracle))) ---> this configuration is a static registration!, my secondary database was configured for dynamic registration, The static registration on standby side is mandatory ?,or there is an alternative ? for example on the standby specify only in the sqlnet.ora
DEFAULT_SDU_SIZE=32767?
Any suggestion may help me enough
Thanks

Hello,
I guess it all depends on what you expect fro the standby. What kind of protection mode are you using? Do you have any delay configured? Is it doing real time recovery? And more.
Can you be specific regarding the requirements that your organization has for this DRP?

Oracle Dataguard configuration

RDBMS:oracle 10g
OS: Windows 2003 server
I have one db server and one standby server.I want to user Dataguard for centralized monitoring.I have another(3rd server) for DataGuard .When I make configuration It connects to server and make configuration successfully.
In this scenario configuration exist on Server (main DB) with which I connect.I want to store configuration on my third server,so that in case of failure I may use it.
How can I configure my third server to store configurations for my Db server and standby server?

If I understand your question, and I may not, the third server is meaningless ... there is no configuration to store anywhere beyond using good backup practices and RMAN.
If you want something to help you manage the configuration look up DGMGRL in the docs.

Dataguard Configuration under Juniper Firewall

Dear Friends ,
We are using Oracle database 11g with Oracle Ent Linux 5.8. We are using active dataguard in this system . Recently we are deployed firewall both on PRIMARY and STANDBY end . we are using juniper firewall device . After deployment of Juniper Firewall on STANDBY end , we observe that Dataguard replication is not performed , i mean log of the PRIMARY server does not transmitted to the STANDBY end .
Does is there any recommendation using firewall device with DATAGUARD ?
How can I resolve this Dataguard replication problem under the Firewall ?

The firewall simply placed on top of STANDBY database . nothing is configured in firewall . I mean all ports are open and no rules are applied yet .
Before firewall , redo transmitted successfully but after placing the firewall , it is not working .
It means you agree the firewall is blocking the transmission and it also means that ports are blocked.
On top of what have been said -
Check the connectivity to Standby from Primary as SYSDBA ?
Check the Primary database & Standby database alert log ?

SAN based restoration or RMAN restoration for Dataguard configuration

Hi ,
We have oracle 11gr2 on aix OS ,I am planning to configure active dataguard for DB size 250 GB.
FOr DB restoration on standby side if i go for SAN based OS block level Relication between primary and standby how to link DB LUn on standby which are mounted with diffrent LUN name on standby DB.
OR RMAN restoartion is only method to go for standby DB restoartion ..
My conncerns is if i go for RMAN than it will take more than 8 hours and it will affect my DB performance ..
Please help me suggest which approch is better ? If it SAN based than how to link LUn to DB file .
Thanks in Advance.

Add line break in Configurator tool tip?

Just started using the Configurator, what a great idea.
My first attempts at tool tips often get lengthy. If the width of the panel is not wide enough, resulting tips get truncated/munged.
Is there a way to insert line breaks in tips so that they can be seen in total on a "skinny" panel? Or is there another approach?

Oracle Streams - Dataguard Configuration

Dataguard<------Streams<----Production------> Dataguard
I'm planning to implement a 4-way System where My Production Database with its own Physical Standby will be streaming(Streams database) to A reporting Database with its own Physical Standby.So,Effectively My production database,Especially it's redo logs will be put under severe load.I would like get some light on the feasibility of such a Setup.What parameters can i Take care of so as to make it a profitable High Availability-High Preformance System?
Any suggestions and advice will be highly appreciated..

Remember that Streams check the source DB name of the LCR. Thus the db_name of each standby must be the same as the of the open DB of the remote DB will reject the LCR of the standby when it is activated.
Also streams, dataguard and crash don't fit so well in respect of streams consistency. At the crach time, some transaction will be lost that would have already been sent by streams, since streams react beneath the second. Thus when you activate the dataguard with its loss of some data, you are going to miss some source transaction, that would have already been replicated. You may end with errors on target site, either being dup val on transaction or OLD value in target do not match new value in LCR.
You can't avoid 100% this but you can decrease its extend. Use as method the 'LGW asynct' as dataguard destination.
LOG_ARCHIVE_DEST_2='SERVICE=boston LGWR ASYNC'
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/log_transport.htm#i1265762
This requires to create the standby redo logs on the dataguard DB (and also on the source DB, since it may becomes itself the standby) so that LGWR updates the remote redo as soon as it can ('async' otherwise 'sync' means that the commit on source is done AFTER the commit into the dataguard and you don't want that).
From my own observation the 'LGWR async nowait' lag usually under 1 sec behind production, which is very good.
