Data Guard :: How To Create Standby Database Using RMAN
Jul 25, 2011
I am trying to create the Standby database using RMAN.
I have first created an auxiliary instance followed by the password file for the instance and the registering it it listener.
Below are the parameters of the pfile of the standby database and followed by the command issued at the RMAN prompt.
PFILE parameters [STANDBY]
orcl.__db_cache_size=293601280
orcl.__java_pool_size=8388608
orcl.__large_pool_size=8388608
orcl.__oracle_base='F:appdsharma'#ORACLE_BASE set from environment
creating the standby database from Active database using RMAN and getting the below issue after i executed the duplicate command.
Version of Database:11g(11.2.0.1.0) Operating System:Linux 5 Error: RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of Duplicate Db command at 12/21/2012 17:26:52 RMAN-03015: error occurred in stored script Memory Script RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor [code]....
provide any work arounds to proceed further in creating the standby database.
We already have one standby database, but now, I want to create another standby database on another server, which ultimately I will make primary and then replace and destroy our current primary/standby databases.
Also, just for the heck of it, I tried to look in our DB Console, and the "Add standby database" is grey'd out.
Is this because I am only using DB Console, and not Grid?But if that were the case, why would the option even be in DB Console, or perhaps is there a lmiitation to the number of standby databases you can manage with DB Console?
I would need to create a physical standby database for DR without using data guard. I like to know in more details like
1. What would be required to switch over to standby database in case of failure of primary database? Is it going to be a manual process each time, or can be automated using scripts? 2. How the archive logs will be applied to standby database in timely manner to sync with primary database? 3. How the Primary database will be synch with Standby database once the issue resolved on primary database. 4. Where do I get a complete script to create physical standby database on Windows platform?
I have dataguard configuration operating in maximum availability mode with a local standby db (A - lgwr sync not using real time apply) and a remote standby db (B - lgwr async). I then simualted a crash of my primary database with batch jobs running. Since the stby db A is in lgwr sync option ,all the commited data in the current online redo log has been transmitted to stby A and is present in its stby redo log (Group 2).How do I apply this stby redo log to the remote stby db.
Tried the following methods.
1.ftp the stby redo log to the remote db and tried to regiter it, got an error that it is not completely archived.
2.issued the recover standby database command and supplied the stby redo log when it asked for the sequence in the stby redo, got an error saying there is corruption in a block(tried this option multiple times ended up with the same result.)
Can i setup physical standby without RMAN? I want to create a fresh single physical standby without RMAN .. If i copy all files in another system and take the controlfile from primary as alter database create controlfile for standby ... and fill all the gaps with archives.. Should it work ? i am on 10G Rhel 4 linux.. and both machines would have same config
I have One Production and one logical standby database . Due to tape problem we are unable to take backups of primary . And due to business , we cannot take back up on disk in hot period(Bank database ) .
If i take logical standby database backup(level 0 ) using RMAN , then will i be able to restore it on production dtbs (In case Production down) ? . Logical standby is in sync with primary .
In my environment Oracle database 11gR1 is running & dg is configured i.e >> 1 primary & 1 standby. In near future space issues will arise for standby. I want to create 1 more standby with max disk space, but how? Active dataguard is configured where report are generated from where & what changes should be made in Primary pfile & new standby pfile.
I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply 2)Apply patches on logical standby database 3)let the name server point to the backup site 4)Apply patches on the primary database 5)Start SQL apply 6)Let the name server point back to the production site
If flashback is enable in physical standby database 1. If we failover at 11AM can I flash back NEW primary database to 6 AM ? 2. if I convert physically standby database to snapshot standby database at 11AM , Can I flashback snapshot standby database to 6 AM and do some works on it (DML operations) then converting the snapshot standby database into physical standby database ?
I want to get the execute plan of a sql in standby database(read only),but failed,how can i do?
SQL> explain plan for select count(1) from hxl.tb_objects; explain plan for select count(1) from hxl.tb_objects * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 2 ORA-16000: database open for read-only access
DB1 <Primary> - Production DB2 <Physial Standby> - DR
I will need to startup my DB2 in DR segment for testing.If i perform the below, will it affect my Production DB? I need it to be up and running as well.
DR: recover managed standby database cancel; shutdown immediate; startup nomount; alter database mount standby database; recover standby database until cancel; alter database activate standby database;
I need to drop standby database completeley and rebuilt physical standby for the same database. We identified there are lot of inconsistencies between primary and standby. How do i need to remove the standby? And what is the best procedure?
I was able to create the standby database on different server with the same name for the primary and standby database but I want to know that can I create a standby database with different database name than that of the primary database server.
I have installed oracle 11g standard edition one and created both primary and standby database. now i want to know how to switch(convert) primary database to standby database.
i have configured physical standby in my local system, to check logshipping i created a table at primary db, wen i tried to check in standby, it says table does not exist..below are primary & standby alert entries..
Primary alert log

3)wen i try to open standby database in read only mode gives below error..

I was using physical standby but my primary database had had some HW issue.So I had activated standby database to handle production.During 3 months, standby database was our live database and our old primary was unavailable.Now HW issue on primary has been fixed.And I want to set again my old configuration : means set primary and standby db.
