Dataguard upgrade

system: solaris 10
Oracle: 9207
physical data guard using broker is running on oracle 9207, want to upgrade oracle 9i to 11g what will be steps to upgrade? how standby site will upgrade?

I would suggest looking at Metalink not 601807.1, the 11g Upgrade Companion. This gives a good overview of the upgrade steps required, as well as informing you of expected behavior changes, other useful documents about specific environments (e.g. RAC), and so on. For example, you'll find specific information relevant to your scenario such as a link to the chapter in the Data Guard concepts manual that talks about upgrading using SQL Apply:

Reg upgrade of Physical Standby from 9i -10g

hi guys,I'm planning to upgrade my database from 9i 9.2.0.7-10g 10.2.0.3...along with Physical Standby Site....
I got a link for Dataguard upgrade
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/upgrades.htm
what I conluded from this links is...Just writing the high level steps
-Apply all the Archive logs on Standby
-install the Oracle Software on Primary Standby
-Upgrade the Primary
-Start the Standby with password file and spfile from the new home..and set the FAL parameters
I might be missing some steps here
but
I just wanted to make sure we actually dont upgrade the Standby as we do with Primary just installing the 10g software on Standby as well and starting the instance with spfile from 10g home with same set of datafies....is considered to be the upgrade.......of Standby database????????looks too simple
Thanx

You could certainly reinstall Apex to make sure that Apex-related packages and procedures are re-granted properly, but that still won't solve the other cases where specific non-Apex-related packages were granted but became "ungranted" after the upgrade. I'm not involved with DB upgrades myself, so the whole procedure is a bit "black box" to me, so I don't know if packages that were granted become revoked on an upgrade. Talk to you DBA about the DB upgrade and find out what packages were granted by default.
but we may get other errors down the line because of other privileges that are still missing...Probably, and depending on the exact 10g version you installed, there are other DB bugs that will mess with Apex. Was this upgrade done on a test instance first or just production? In either case, run through all your applications and see if anything else breaks. If possible (and appropriate) notify your users that an upgrade occurred and that you've tried to resolve any problems but some might be hiding out there. It's not bad to be cautious--we tend to run things the other way and upgrade overnight, do a few checks to see that nothing is 100% broken and come in the next morning to all kinds of fun errors the users found.

Oracle 9i database software upgrade issue with standby (Dataguard) database

All,
I have encountered a problem in upgrading the Oracle software on 2 of our databases in-house. The databases in question here are using Dataguard, so one is set to primary and one is set to standby. The version that they are/were starting at is 9.2.0.7.
I was able to install and complete the 9.2.0.8 and 9.2.0.8 OCT CPU patches on the primary database, however when I moved to working on the standby database, I am got an error when attempting to follow step 6 of the post installation tasks:
Enter the following SQL*Plus commands:
SQL> STARTUP MIGRATE
SQL> SPOOL patch.log
SQL> @ORACLE_BASE\ORACLE_HOME\rdbms\admin\catpatch.sql
SQL> SPOOL OFF
(Please note that this is my first experience with working with Dataguard, so my methods in updating might have been a bit off-base.)
If I attempt to startup the standby database in MIGRADE mode, I get the following error (which is expected):
ORA-01666: controlfile is for a standby database
If I try to run the catpatch.sql script, even after mounting the database in standby mode, I receive the additional error:
ORA-01219: database not open: queries allowed on fixed tables/views only
My question here is, how do I get the standby database to allow me to finish the software upgrade process, so that both versions of Oracle match on the primary and standby databases? :)
(I did try some research on Metalink, but only found an article detailing how to upgrade your dataguard database from 9i to 10g, which did not look especially helpful in this case...)
Thank you!
-Sabrina

Depending on the kind of Dataguard you currently have, physical or logical, there are two useful metalinks notes:
Upgrading to 10g with a Physical Standby in Place
Doc ID: Note:278521.1
Upgrading to 10g with a Logical Standby in Place

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!

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.

- How does upgrade happen in dataguard configuration?First you patch the Oracle binaries on both primary and standby. Then open dataguard services and upgrade the primary database, standby will update itself already.

Database upgrade in Dataguard Broker Environment

Hi All,
OS: Wndows 32 bit
DB: 11.2.0.1
We have an upgrade activity due, in this, we have a windows Primary Database and it has 2 Physical Standby databases. There is no concept of Near DR and Far DR. Both the databases are getting sync'd directly from the Primary database.We are also using Dataguard Broker. Following is the skeletol POA for the same:
1. Install an out of place DATABASE Software (11.2.0.3 ) on both the Standby databases and also the Primary database.
2.Disable the configuration of the database broker on all the 3 servers
3.Copy the files init/spfile, tnsnames.ora, listener.ora, sqlnet.ora and the password file from the old oracle home to the new oracle home location on all the 3 servers.
4.Take a clean shutdown of the Standby databases only and then stop the services and delete the services as well.
5.Get into the new oracle home and create the oracle services for both the standby databases
6.Once, the services are created, mount both the standby databases and enable their recovery.
7. Now, we will connect to the Priamry database server and start the upgrade here. I will be using the manuall method of upgrade for the database here which all includes all the pre and post tasks.
8. Once the upgrade is done succesfully on the primary databases, the changes will be automatically replicated on its 2 Standby databases as well.
9. Post this, we will enable the broker configuration and check for the syncronziation by doing some switch's.
10. Lastly we will remove the old oracle home's.
Any suggestions?
Regards,
SPhinx

After the upgrade the home directory will change and all I need to do is change the home directory path in the extract/replicate prm file correct ?
this what I will do :
1. stop GG services on both source and target
2. upgrade the db.
3. change the path of the db in the prm files as required.
4. start the extract and replicate process on source and target respectively.

Oracle upgrade with DataGuard

Hello Experts,
We have to upgrade oracle db from 10.2.0.2 to 11g.
While upgrading to PRD system there is DR system also, which uses DataGuard for archive update on DR system.
I would like to know that we need to take special care for DataGuard or DBUA will take care of DataGuard mechanism?
Thanks in advance.
Regards,
Yogesh

Hi Yogesh,
in a SAP environment it is even more specific than the standard oracle upgrade guide (because of the compatible parameter and SAP scripts).
We discussed this already in this thread: Upgrade to Oracle 11G in standby environment

How to upgrade the 10g Dataguard after the primary was upgraded to 11g

Hi
What is the best procedure to follow to upgrade my 10g physical Dataguard after the 10g primary was upgraded to 11g ?
I was planning on stopping archiving of hte primary prior to the upgrade and enable after.
Do I need to reastablish my Dataguard from scratch ??
Old verison : 10.2.0.4
New version : 11.2.0.1
Thanks in advance

10g RAC upgrade to 11g RAC

How to perform 10g RAC upgrade to 11g with Dataguard in place?
OS=LINUX
RDBMS=10.2.0.4
DG=PHYSICAL STANDBY
Below is my understanding
1)Install 11g CRS in NEW_CRS_HOME
2)Install 11g in NEW_ASM_HOME
3)Install 11g in NEW_RDBMS_HOME
4)Export the new NEW_ORACLE_HOME and start up the database with startup upgrade.
5) Run the catupgrade.sql script.
Are there any other steps involve?
In case I have to rollback then how to rollback CRS.

Personally I would use DBUA instead of catupgrade.sql, but make sure you follow the upgrade documentation for pre-checks etc. You will also need to use netca to recreate the sqlnet listeners in the 11g homes and register with 11g CRS.
CRS is generally fairly quick to re-install and re-register databases, and this is cleaner than trying to restore OCR and VOTE disks etc. If you prefer to rollback be sure you backup the OCR and VOTE disks (e.g use dd), backup /etc/oracle, CRS_HOME, /etc/init* scripts etc.
The dataguard standby database should roll forward through the upgrade, but you will need to manually register the standby with 11gCRS. Make sure you have your DB and Log create_file_dest's set, as well as standby_file_management=auto. Personally I would manually recover the standby after the upgrade in case I need to use it to fallback.

Switchover problem after upgrade from 11.2.0.1 to 11.2.0.2

Hello
I succesfull upgraded my database from 11.2.0.1 to 11.2.0.2 on my test enviroment.
My enviroment works with dataguard configuration.
Data Guard management is dgmgrl.
OS is Linux Redhat x86_64
I have problem with switchover operation:
During switchover operation (with dgmgrl) new primary database is switched succesfull but problem is with new standby database, I have message:

ORA-01194: datafile 1, needs more recovery to be consistent
ORA-01110: datafile 1: '/u01/app/oracle/oradata/DB1/system01.dbf'
To end switchover operation I should start new standby instance. But if i try startup It i have:

Steps to upgrade RAC wit Standby Database ?

Hi All
I have RAC environment with 8 Nodes (Linux 4) , I have one node as physical standby for this RAC.
My oracle is 10.2.0.3 , and i want to update it to 10.2.0.5
Could you please advice me with steps , when i Google i found that i have to start with standby then Clusterware ?
Any recommendation ?
Thanks in advance.

Hello, look at the documentation of Dataguard Concepts and Admininstration http://docs.oracle.com/cd/B19306_01/server.102/b14239/upgrades.htm#SBYDB1200. There's a chapter "B Upgrading Databases in a Data Guard Configuration"

Step to setup the Dataguard in 11.1.0.7

Hi
We have completed our upgradation to R12.0.6 and 11.1.0.7 on server A(Appl),ServerB(DB) and we need to set up the dataguard on server c , can some body gives me the detail steps required for setup and failover check to carried out in this process. or please give me some pointers to this
Regards

Hi,
I believe the document for configuring Data Guard on R12 with 11g database installed is not yet available. However, you may refer to the following documents as the steps should be the same.
Note: 452056.1 - Business Continuity for Oracle Applications Release 12 on Database Release 10gR2 - Single Instance and RAC
https://metalink2.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=452056.1
Note: 753241.1 - Case Study : Configuring Standby Database(Dataguard) on R12 using RMAN Hot Backup
https://metalink2.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=753241.1
Log a SR, and check with the support whether this document will be released or using the above documents is enough.

Oracle 10g RAC to 11g RAC Upgrade on Solaris

Hi,
We are planning to do a migration of a 4 Node Oracle 10g RAC on Solaris 9 to 11g with Solaris 10. We'd like know what would be the best path to take. We cannot afford any downtime!
Options: Are these feasible? Which option is best? Any documents links?
a) Do a rolling upgrade of Oracle from 10g to 11g. Then take down individual nodes and upgrade the Solaris OS from 9 to 10 and bring them up back into the cluster. Is there any known issues taking this path? Is a rolling upgrade like this possible?
b) Do an upgrade of the Solaris OS from 9 to 10 on each node and then bring them back up? Is this practical? Does Oracle allow different versions of OS running on different nodes?
c) Use Dataguard with 2 different RAC environments (2 nodes each). How would this work? Is it the only possible way? Any steps please?
Thanks

first of all i would not change several components (OS, database version) at a time. My recommendation is to make small steps and start with the operating system first. Seconds recommendation is to test and test everything in your dev or test environment prior doing the upgrades in the productive environment. Trust me: You will face problems :-) So you better try it beforehand!
b) Do an upgrade of the Solaris OS from 9 to 10 on each node and then bring them back up? Is this practical? Does Oracle allow different versions of OS running on different nodes?As far i know you can run different operating system versions on different nodes if they are supported (Solaris 9 and 10 are).

Whats is diffrence between Dataguard and Stand by?

Hi All
I was asked for diffrence between Dataguard and StandBy Database in an interview.
I answered that prior to 9I, (in 8i) It was called StandBy Database and from 9I onwards, It is called DataGuard.
But interviewer doesnt seems to be satisfied with my answer. Not sure why?
Then i was asked for Diffrence in Logical Dataguard and Physical Dataguard?
I replied with "Logical DG" is one in which sql stements are applied onto standby whereas "Physical DG" is one in which redo logs are shipped from one server to other by itself (with services) and secondary upgrades itself from those. Again, interviewer didnt feel happy enough.
This has made me think, was my answer incorrect because i answered whatever i know. which i feel like is correct.
Please help me identify correct answer.
Thanks

A Data Guard 'configuration' actually includes the primary database and one or more standby databases as well as some additional processes and the connectivity between these things.
In simplistic terms:
Standby Database is an operating mode of the database in which it continuously applies redo logs that are shipped from another (primary) database. The mode of operation often stops the database from being accessible to users.
Logical standby database uses a 'recieving process' (SQL Apply) that extracts from the log and creates SQL statements which are applied to keep the standyby database in step with the primary.
Physical standby database uses a form of continuous database recovery by directly applying the redo logs received from the primary.
Data Guard was originally a set of scripts, but now is the entire environment including a set of processes that control the extraction of redo (directly from log bugger, from redo logs or archive redo logs) from the primary, shipping to the standby, ensuring that the logs are applied. Data Guard processes also include the mechanics needed to make the standby database active automatically (failover) or manually (switchover) and also to re-sync and make the original database active again (switchback).
You could (should) read more about this. Oracle has a fine set of documentation which you can access from http://tahiti.oracle.com - indeed selecting Database 10gR2, and switching to the Books tab you get to http://www.oracle.com/pls/db102/portal.portal_db?selected=3 . And by scrolling down a little to "Data Guard Concepts and Administration" you would get decent introduction in the first 2 pages of Chapter 1 "Introduction to Oracle Data Guard".
But interviewer doesnt seems to be satisfied with my answer. Not sure why?I would not be satisfied either. Especially if I was looking for swomeone to be responsible for availability scenarios for my corporate data.

Again, interviewer didnt feel happy enough.Well ... you are moderately close on this. However, you seem to be missing "how do we get data from the primary in the SQL Apply case". The implication is that you are not at all comfortable with the basic concepts.
Again, I would not be terribly happy either. I would not be confident that you had read Chapter 1 of the Data Guard Concepts manual. And that could imply that you had not read Chapter 1 of ANY of the Concepts manuals. That chapter in each of the manuals is an easy read, complete with pictures, and it describes the basics of operating the big machine that the interviewer wants to entrust you with.
All that said, Data Guard is only available on Enterprise Edition. Standby capability is available on Standard Edition. And there are commercial products around that provide capability similar to Data Guard for Standard Edition.

DataGuard on Oracle 9i and Oracle 11g

Hi Guys,
Is it possible to configure DataGuard between an Oracle 9i primary database and an 11g standby?
Thanks for the help.
Carlos

See this MAA paper - http://www.oracle.com/technetwork/database/features/availability/maa-wp-10gr2-rollingupgradebestprac-1-132006.pdf which explains a rolling upgrade using a Data Guard standby. The caveat is that you will have to create a 10.2.0.4 physical standby on the new hardware and convert it to a Logical Standby before upgrading it to 11.2. So you will have to have both homes on the new hardware. So your database has to be able to support a Logical standby.
Also, depending on the hardware change the combination has to be a supported one as detailed in the MOS note " Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration" [ID 413484.1]
Going from a single instance to a RAC is no problem.
Thanks.
Larry
