Physical standby 10gr2

I am running a query which takes 2minutes. the same query if i run on primary of physical standby (maximum availability) it takes 8 minutes. why this behavior.

Are you saying that the QUERY is slower in PRODUCTION when using LGWR SYNC ?
So it is LGWR SYNC that causes the query to be slow ?
Is your query fetching a lot of data (large number of rows, columns with large sizes) to the client ?
10mbps is very slow. Most server side LAN connects are 1Gbps, certainly not below 100Mbps. Check to see if the Network Interface on your server / network is saturated.

Open your Physical Standby in read only mode and do your export. Then mount it back in managed recovery mode.

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.

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 PM

If 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.

Rolling Upgrade of Oracle 10gR2 RAC with Physical Standby (DG)

Hi DBAs,
I want to do a rolling upgrade of Oracle 10.2.0.3 (2 node RAC+ASM) with Physical Standy Dataguard to Oracle 10.2.0.4 also applying CPU (April2009).
Please suggest the best way to perform this upgrade and patching with no downtime.
Thanks
-Samar-

Unfortunately rolling upgrade is only possible with a logical standby in place:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/upgrades.htm#CHDBJAGG
That doesn't help you at this time, but 11g has a way to do it with a physical standby. Even here you need an intermediate logical standby:

Well, it is simply warning that "Creating a physical

database, requires manual RMAN intervention to resolve OMF
datafile pathnames.
NOTE: Please refer to the RMAN documentation for procedures
describing how to manually resolve OMF datafile pathnames"
For instance, the path for the logfile name in "ALTER DATABASE ADD STANDBY LOGFILE 'srl5.f' SIZE 52428800" may need to be changed manually. It is advisable to check the mentioned documentation.

Upgrading from 10.2 to 11.2 using Physical Standby

Hi
We have a 10GR2 EE database in a RAC cluster and we want to upgrade the 10GR2 database to 11GR2 non-RAC on a different server.
We'd prefer to do this using a Physical Standby to avoid down time as much as possible.
Any suggestions as to the best way to do this?
Thanks

Streams or Physical standby?

I have a scenario here as below
I have an Oracle 10gR2 database server in state A and would like it to be replicate over to a new database in State B. Db server at State A is the primary server which will be access by users and DB server at State B will be use only if Server at State A is crash or down. So which approach should I use?
Streams or physical standby?

ya logically from the scenario it is more suitable to use dataguard physical standby than Streams but my worry is would it be a problem (e.g: unstable WAN) for this approach since it is going to be go through the WAN? From my experience dataguard physical standby server required to be rebuild from the production server(which required a downtime) when it is not in sync or something?
Just to let you know that the user required to access the server once the primary server is down(regardless is server crash or WAN network down)DataGuard can afford a Gap, it depends on how long the gap was sustained for, on busy databases a few hours can be enough, i had a database that went down and i could speed-apply redo logs 5 days later.

Physical standby databasse issues

By mistake we deleted around 600 archive log files from primary location before it applied to standby database, and we don't have any backup of those archive logs. Its a physical standby database. Is there any way to fill that gap without affecting the primary database.
- Mano

Assuming its Oracle 10gR2, you can take RMAN incremental from SCN backup of primary database from the point where your standby is out of sync. Move RMAN backup pieces to the standby database server and recover standby database.
Oracle documentation is worth looking at:

Tns entry on client machine for a physical standby!

Hi all.
i am working on 10gR2 on RHEL4.I have created a physical standby on the same host. The primary and the standby database has different sid as prod and prodsb
can i have one tns entry on the client machine so that they can connect to the database even after teh switchover or failover??? or will they have to change the connection string while connecting to the database??

Physical Standby re-sync

Hi,
I have gone through the following link in order to re-sync my physical standby with the primary db . The physical standby had nearly 2500 archive log gap but resolved based on below link :
http://www.bestremotedba.com/oracle-10g-dataguard-sync-standby-database/
The above is valid only for 10gr2 or above but in Oracle 10gr1(10.1.0) i am not able to take the primary db backup based on SCN . Could anyone let me know whether there is any alternative for it? I know 10gr1 is outdated but we have already planned for upgrade in near future but for current situation I have to re-sync my standby with the primary and the standby has nearly 2000 archive log to be applied . We dont have enough space for restoration of archivelogs. It was unfortunate that I have not monitored the standby.

As you said this feature is available starting from *10gR2* only
AFAIK, you have to either restore those archives (or) re-create standby database.
If you do not have much space, try to restore less number of archives, apply them later you can clean up & again start restore. its hectic.
So it depends on your log file size , lets suppose 50mb then
2000 * 50mb = 100000 mb(~100gb) , its painful, Check what is database size. Then compare which will be quicker.

Can read-only standby be cascaded from another DR physical standby

we are going to have one two-node RAC database in the primary site (site A), one Data Guard maintained standby database in the DR site (site B) and one ACTIVE Data Guard maintained read-only database for reporting (site C, on the same subnet as site B). My question is what is the best practice for the data guard configuration in terms of the redo log transportation, Is it possible to set up relay of redo log transport from one physical standby to another (database version 11gR2, data guard in Maximum Performance Mode):
1)     A->B->C (minimum overhead to primary site A, maximum delay to report site C)
2)     A->C->B (minimum overhead to primary site A, maximum delay to DR site C)
3)     A->B; A-C (maximum overhead to primary site A, minimum delay to site B and C)
Are all three configuration possible, which one would you recommend?
Any discussion document or white paper about the above configuration you can point to for me (I gather the scenario may be rare, but multiple physical standby instances set up are not uncommon, if to ignore active data guard part) ?

Data guard synchronization after link down b/w primary and physical standby

Hi All,
I have configured data guard on oracle 11gr2 db. Normally switchover between my primary and physical standby happens smoothly and the Apply lag would be zero. Recently We had to test a scenario when the network link between Primary and Physical standby is completely down and Physical standby is isolated completely for more than half an hour.
When we brought up the link every thing worked smoothly but apply lag started increasing from 0 to around 3 hrs. And then it started reducing to 0. Currently Apply lag and transport lag shows 0.
But is this normal behaviour of oracle data guard that when the link between primary and physical standby is completely down, It requires 3-4 hrs for resynchronization ??? Even when during isolation, there were very few transactions happend on primary database ??
Are there any documents available for this scenario??
Thanks

Hi, after the link is up, if there were some transactions and produced archive logs it's normal to take some time for resync. To check if 3-4 hours is normal or not, you can repeat the scenario and this time check
- how many archivelogs does primary produce in this period.
- after the link is up, does archivelog transfer immediately starts from primary to standby? Is primary able to send these archivelogs parallel?
- Is there anything wrong with the apply process?
check primary & standby alert log files, and run this query on standby to check the transport and apply processes:
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;

Drop a datafile from physical standby's control file

Hi,
I am trying to create a physical standby database for my production...
1) I have taken cold backup of my primary database on 18-Nov-2013...
2) I added a datafile on 19-nov-2013 ( 'O:\ORADATA\SFMS\SFMS_DATA4.DBF' )
3) Standby control file was generated on 20-ov-2013 (today) after shutting down and then mounting the primary database...
When i try to recover the newly setup standby using archive files, i am getting the following error (datafile added on 19th Nov is missing)

Hi,
What is your version?
If you added new datafile or created new tablespace, take backup again for restore new created standby database.
If your standby database running well, DG configuration success, then this datafile will create on standby side, too.
Set STANDBY_FILE_MANAGEMENT=AUTO best practice.

Not need any delete datafile from standby side, you must recreate standby database, or you can take RMAN backup and restore to standby side again.
