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):
SQL> create tablespace rmancatlog_tbs datafile '/u01/app/oracle/oradata/NEW/rman_catalog.dbf' size 500M autoextend off extent management local segment space management auto;
SQL> create user rman identified by oracle
2 default tablespace rmancatlog_tbs
3 quota unlimited on rmancatlog_tbs
4 ;SQL> GRANT connect, resource, recovery_catalog_owner TO rman;
RMAN> create catalog;
recovery catalog created
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:

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 :: 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

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.

Data Guard :: Getting Standby Host And DB Name From Primary
Oct 25, 2012I'd like to know the Standby hostname and database name (db_unique_name) from primary using SQL. Simply put, which table in primary datbase gives us the standby host and the database name. I am aware that TNSNAMES.ORA contains details, but we cannot use SQL for that. I am also aware of V$ARCHIVED_LOG's DEST_ID column. But, the DEST_ID will not show the host and the db names, neither does V$PARAMETER's LOG_ARCHIVE_DEST_n if SERVICE parameter is set to Connect Identifier.
If I further paraphrase my problem, how I'd relate a dest_id to a standby host and database using SQL.
SELECT <columns> FROM <v$some_view> WHERE dest_id IN (2, 3);
DEST_ID HOST_NAME DATABASE_NAME
--------------------------------------------------------
2 host2 standby_1
3 host3 standby_2DB version : 10g
