Standby Oracle

Good morning Gurus,
We want to implement the Standby on our Oracle Database 10g production.
We have steps about this procedure. Its like this:
1- Implement and update Oracle 10g using the OPatch, before we start the Standby configuration.
2- Create a virtual enviromment for tests before implement directly in enviromment production.
3- In a date, shutdown the Primary, restore in Standby, configure both init.ora, startup two instances.
Do you agree with us? Help us with yours comments.
Thanks for your time and patience.

If I understand the question correctly the answer is no.
That said, if I'm doing Data Guard I probably would upgrade the database in advance to save trouble down the line.
A comment on Opatch since I just did the CPU patch on 11 Data Guard systems.
On the standby server all you do the in run opatch apply. Skip the SQL part as this moves from the primary database.
Also there's a separate Data Guard area here :
Data Guard
The Oracle product manager for Data Guard is on there almost every day and he's the best in the business.
Does this help?

Manual standby Oracle 11.1 standard edition

I have set up a standby DB for Oracle 11.1 standard edition.
Everything is done manually by using batchfiles and scripts.
Logiles are copied from the primary server to the standby server but when I try to register those I get an error ORA-00439: featue not enabled : managed standby
Do I need enterprise edition for this ? I thoguht it was possible to set up a physical standby if you do the logshipping yourself without using data guard.

Yes I know data guard is only available in Enterprise edition.
Hence I scripted the whole process and copy the archive logs myself.
So this means that doing this manually also won't work since it won't let me register the logfiles. I have done this in Oracle 10 standard edition. Guess my customer will need Enterprise version as from V11 then...

Switchover to 1 of 3 Physical Standby (oracle 10g R2)

Hi all,
Previously I already had done switchover primary to standby (only 1 Physical standby was in the configuration)
now i have some additional physical standbys (3 Physical standbys)
stby1
stby2
stby3
i want to switch to stby1 ,what needs to be done at stby2,stby3 to make them capable of identifying stby1 as their new primary.
Kindly suggest!

Welcome to OTN,
Once you performed switchover, You need to perform changes with some parameters from standby FAL_SERVER
Earlier this parameter points to old primary, Now after switchover you have to put service name of new primary database service.
Also Make changes with remote destinations log_archive_dest_n with correct service names.
Refer this manual to work with multiple standby databases.

Primary and standby oracle server versions

Hi
Can I have a dataguard config in which the primary database and standby database are having different Oracle versions but the compatible paramerter is set to less than the lowest version
Eg:
primary 10.2.0.1
Standby 10.2.0.4
compatible 9.2.0.0.0
Is this possible
Similarly is it possible to have primnary and standby in 10g and 11g with 10.2.0.1 compatible parameter

Can I have a dataguard config in which the primary database and standby database are having different Oracle versions but the compatible paramerter is set to less than the lowest version
primary 10.2.0.1
Standby 10.2.0.4
compatible 9.2.0.0.0
Is this possible
Similarly is it possible to have primnary and standby in 10g and 11g with 10.2.0.1 compatible parameterNo it is not possible. I read one of blog, We can configure logical standby it might 11g

Standby Oracle 8.1.6

Hi,
We have Oracle 8.1.6 as a production database and Oracle 8.1.6 as a standby one on a second server. Secondary database doesn’t work from 2004. I can not connect to the standby database. Moreover, we do not have any username and password for it.
I would like to start up secondary database.
I’ll appreciate any suggestions or links.
Thank you,
Konstantin

If the standby hasn't work for years, it's not quite possible to sync it with primary. Of course if you have all the archive logs in these years, you could but it's not as efficient and fast as rebuilding it.
Follow the Oracle doc to build a new standby.
http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a76995/toc.htm
btw, it's time to plan upgrade your server.

plz help me out to solve this ..What is the version you are using?
Even though your primary database is in noarchive log mode before configuring data guard, still its not a problem. Follow high level steps as below
1) Take missing datafile on primary using RMAN (or) you can use tablespace backup with traditional method
2) copy that datafile from primary to standby system
3) Ensure you have properly set for DB_FILE_NAME_CONVERT(bounce required), and set standby_file_management to manual
4) take the dummy file and rename with the new file(step 2) by using alter database create command
5) later change standby_file_managment to auto & start MRP

Oracle diagnostics on standby

Oracle Standby DB with SAP - BRARCHIVE and BRBACKUP

Hi experts,
I was requested to configure and standby Oracle scenario for with SAP. After reviewing many different documentation regarding this, I would like to confirm the following with youu2026How do the BRARCHIVE and BRBACKUP tools should be integrated in this standby/data guard configuration? Actually data guard configuration has been already completed and redo logs are being shipping and applying successfully from primary db to the standby db. Please note that no settings for BRACRHIVE or BRBACKUP have been done so far.
From doc. u201COracle White Paperu2014Setting up Oracle 11g Data Guard for SAP customersu201D, it says that u201CThere is no change to BRARCHIVE configuration necessary. It can work like with any other standolane databaseu201D. What changes or considerations would be required on the current data guard configuration to implement these BRTOOLS? For exampleu2026If I start using BRARCHIVE to copy the offline redo log files from the production database to the standby database, its necessary to disable anything from the current configuration?
Hope I was clear enoughu2026thanks for your help.
Regards

Hi Orkun,
If the use of BRARCHIVE is not required or at least is not mandatory to configure an standby db for SAP environments...I've started thinking If I've followed the right process to complete this?
As mentioned if my post the following documentation was used "Oracle White Paperu2014Setting up Oracle 11g Data Guard for SAP customers". Did I follwed the right process or is there any different set of steps to configure Oracle standby DB for SAP using BRARCHIVE and BRBACKUP?
As you can see I'm confused about the Standby DB configuration process for SAP environments.
Any clarification you can provide me regarding this would be highly appreciated.
Regards

Any help is aprreciated

Hello;
Odd setup ( No offense ).
This error is not a listener issue generally. In fact if the Standby is in Mount it could be normal.
Error ORA-1033 is expected for connections when they attempt to connect to standby instance, because it is mounted and not open.
Can you try to connect as sys from the Primary to the Standby and then the other way. The Primary to Standby connect should error.

There was a large debate about having multiple listeners in the General forum a while back which I stayed away from. I try very hard not to tell people strong opinions, sometimes its very hard.
But in this case I would consider ditching the multiple listener setup. I believe it gives you nothing, and just makes things more complex.
Here's that thread :

Any other solution instead of edit the controlfile and stop/start tghe database?
thank you!!!!

Hello;
Well Oracle thinks the files are there, but I remember a bug on metalink where the controlfile still had them, but they were not on the file system. Can you confirm they exist?
Meanwhile I check my notes for the Oracle doc nunber.
Bug 6128242: TRYING TO DROP STANDBY LOG FAILS WITH ORA-19528
So if you are Oracle 10 this might be the issue.
workaround is to re-create the controlfile without the incorrect logfile. ( Yuk!! )
ORA-01156 When Adding Or Dropping Redo Logs [ID 452152.1]

Oracle post failover transaction commit error

I have a problem on trasaction after database failover.
Solaris 8, WLS 6.1 sp3, Oracle 8.1.7 (2 Oracle instances, one is primary and
another is standby), JDK 1.3.1
We found this problem in Oracle (Net 8 connection time) failover test.
Here is what we did.
During the load, we shut down the primary Oracle server (box).
All in-flight transactions were wrong, this is ok.
When new requests came in, WebLogic begin to refresh the connections.
Because the primary Oracle server was down, it took about 70 seconds to
refresh a connection (due to the socket timeout value) and redirect to the
standby Oracle. This is fine.
After a while, all connections were refreshed and all connected to the
standby serever.
When I opened WebLogic console to monitor the in-flight transaction, I found
some transactions are doing committing and never finished.
At this time most of the transaction can go through but few of them through
an exception (attached at the end). This error could never gone although the
frequency was not high. The strange thing is I checked the database, the
data was committed.
I've tried Oracle OCI driver and thin driver, both had this problem. Is
there anyone can help me on that?
Thanks,
Wenji

Things could be more complicate. I did some tests to find the details of the
problem. Here are the results.Hi,
This is developing into a bigger problem than I can solve informally in newsgroups,
so I suggest that you open an official support case with this information.

1. I've done a test. In this test, I shut down the Oracle and also stop the
load. After all threads and connection returned to the pool and all
transactions done (roll back or abandoned), I started load again. I still
could find this error. That means this error is not related to any in-flight
transactions.
2. After all connectioin failed over, this error was still not gone. The
frequency was not high, but it was always there.
3. In WebLogic console, monitor in-flight transaction, I saw some
transactions were doing committing, but never finished if there was no load.
When I saw an error printed in log, one of the committing transaction gone
but there came out another transaction doing the commit and can't be
finished. I'm not sure if it was related to WebLogic console's bug.
4. Increase the transaction timeout can fix this problem. Unfortunately, we
can't increase the transaction timeout anymore due to our business
requirements.
I hope those information will be helpful.
Thanks,
Wenji

WenjiHi. It seems that Oracle failover is not perfect. Our transactioncoordinator
is supposed to have control of the transaction. If a failover occurs while
a transaction is pending, the coordinator should still have the ability toroll
back the tx. Apparently there are cases where the failover causes an open
transaction to be committed, in such a way that even if the coordinatorhas
decided to roll it back, it can't. These may be when the failover occurswhile
we are waiting for the commit call to return. We either get an exceptionor
we get no return from the commit() call so we try to roll back and fail.The
actual commit succeeded, but we never knew.

Standby Database in Veritas Cluster

Can anyone point me to documentation on the standard/recommended
procedure/configuration to maintain a redundant standby Oracle
database in a Veritas cluster?
Thanks.
Ajay Rajani

We are in the process of establishing the same but still working on how the file systems will have to be arranged for failover
