Data Guard :: Logs Get Shipped But Not Applied - Due To Primary Database Reset
Jul 22, 2013I have a Sap Primry Database and also a standby db that was working perfectly.. We migrated the primary db from windows 2003 to windows 2008 and brought the primary db up.. I had to create a controlfile and do a system copy and had to reset the logs on the Primary.. All came up and when i checked the standby it was receiving the logs but after a month. i see that it was not applying the logs as I think because of the sequence number .. it stopped.
I did the ffg as per the attachement...My logs have been shipped across but not applied, But What worrries me is the log sequence number on my Primary

Data Guard :: Find Archive Log Gap From Primary Database Site?
Mar 23, 2013I am new to Oracle and a beginner in Data Guard.
1) How to find archive log gap from Primary Database site?
2) Do I need the DB_UNIQUE_NAME when setting the LOG_ARCHIVE_DEST_2 ? What is the purpose of DB_UNIQUE_NAME in LOG_ARCHIVE_DEST parameter?
3) If archivelog gap happens standby db goes out of sync with the primary database. What does out of sync actually mean?
4) Primary DB knows where to transport redo data based on the location mentioned in LOG_ARCHIVE_DEST_n of Primary DB. Am I correct in my understanding?
Data Guard :: Redo Archive Logs Missing
Apr 23, 2013While Configuring Data Guard for ORacle 10g (10.2.0.4) 64 bits on Windows 2007 Server 64 bits.I got few questions
1. What is the Default mode of Standby Database?
2. Should we Always Start Physical Standby Database to Recover Missing Redo Archive Log?

How to Apply / Recover These Logs on Standby Database?
Data Guard :: Archive Logs Are Being Shipped But Not Applied
Jun 27, 2013Currently I am at the point where the configuration has been completed, and I just need to sync the standby database to the primary one. I can see in the log files that the archive logs are being shipped, but they are not applied on the standby system.
If I run "recover standby database;" manually in sqlplus I can see that it is trying to apply an archive log which is way too old (ORA-00279: change 9656498443 generated at 04/29/2008 08:45:08 needed for thread 1). I
n the alert log I can also see this error: Warning: Recovery target destination is in a sibling branch of the controlfile checkpoint. Recovery will only recover changes to datafiles.
At this point I was thinking that the standby database might be on a different incarnation compared to the primary, but this is not the case, they are both in incarnation 6:6 6 MVF 4023175798 CURRENT 48493546257 13-06-21

Data Guard :: Transfer Of Archive Log On Standby Database
Dec 9, 2010I successfully created the standby database and the archive logs were properly moving on both the primary and the standby databases. For the proper transfer of the archive logs on the STANDBY database I used "FAL_CLIENT AND FAL_SERVER" in the pfile of the primary database specifying the location of the primary and the Standby respectively.
When I removed both the parameters from the pfile of the primary database still there was the transfer of the archive logs however there should not be "If I am not wrong" as I have removed both the parameters.
why there is still the transfer of the archive logs on the standby database.

Data Guard :: Registering Primary Database To Catalog Database
Oct 9, 2012Here we have a data guard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. Also we configured one schema on a third machine as catalog database using following steps. The steps executed in catalog database(appsdb):

Added tns entries of catalog database in primary and standby. Then from primary database we tried to register to catalog database. It is showing that it is registering. But every query afterwards in rman is throwing the error. Below are the steps and error:

Nov 29, 2011I have a requirement to change the instance parameter of the primary database and standby in the data guard. Any procedure to do the same. I have to do it directly on production and there is no test set up so I cannot experiment . The procedure I am thinking of is as below.
1. Stop the standby
2. backup the primary
3. Change the parameter and restart to make it effective
4. Start the primary
5. Go to stand by
6. Change the parameter and mount the database.
7. Check if both are in sync and apply logs if not.
Data Guard :: Change Server B To Standby Database With A Running As Primary
Oct 4, 2010I new to data guard concept.
I am using oracle 10g with data guard configured , I have primary ( A ) and standby database ( B ) .But because of some unavoidable conditions the primary database ( A ) got shutdown and was not starting , We shifted the standby database ( B ) at new location and changed it to primary with following command ,
startup mount;
alter database recover managed standby database finish;
alter database commit to switchover to physical primary;
shutdown;
startup;
This new primary ( B ) was open for end users for 2 days during which old primary ( A ) was shutdown .
I took the backup of ( B ) and restored it on A AND shutdown the B . Now A is acting as Primary database. Server B is shutdown . I want to change server B to standby database with A running as Primary .Is it possible ?
Data Guard :: Primary Database Is RAC And Physical Standby Is Single Instance
Mar 27, 2013I am using Oracle RAC 11.2.0.3 as primary database, we are going to start using Oracle data guard. So I am designing my infrastructure and planing to use Oracle 11.2.0.3 Single instance as my physical stand by database.
My question is it feasible to have my standby database as single instance while the primary is RAC? is it feasible to build my Oracle single instance standby database from the RMAN backup of the RAC primary database? Is there any restrictions (or any points to be taken into consideration) since my primary database is RAC while the physical standby is Oracle single instance?
in the below link
[URL].......
it was mentioned that primary can be RAC or single and same for standby, but my question is it feasible to have primary as RAC while standby as single instance? or it should be like each others?
The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database. Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.

How To Capture TXs From Archive Logs To Replay On 10g Database
Feb 12, 2013I am looking for a way to capture a TXs from one database and create a script or use it with tool, so we can capture TXs close to production while testing changes being implemented in database.
Env:
OS: Redhat Linux 5.0
DB: 10.2.0.4
Actually Requirement: We have active-active Golden Gate setup done for one of our DB and once a quarter we make changes in the database using DDL (CREATE / ALTER - TABLES, FUNCTIONS, TRIGGERS, etc). We are 24/7 environment and hence no downtime is affordable. What I like to know is a way to capture all TXs from one of the DB and create a script so we can run them while we are testing new changes in the database. Something like DBMS_WORKLOAD_CAPTURE Package (Available only after 11gR1) or some tools available in the market.
I also tried looking into Load Runner but felt it works with App tier than DB, I may be wrong there.
