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.

How to create a standby database without rman and with the rman..?
View 1 Replies View Relatedcreate another standby database on a new server.
I'm running Oracle 11.2 EE on Solaris 10.
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 have a Database of Size approx 150GB. I want to create a standby server(High Availability).
1)If our Primary Database crash, the standy server should instantly start automatically i.e no down time.
2)There should be no data loss.
3)Are Data Guard and Replication similar?
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?
why RMAN is unable to create physical standby database ?
RMAN> connect auxiliary sys/system@DGREPL
connected to auxiliary database: DGREPL (not mounted)
RMAN> connect target sys/system@REPL
connected to target database: REPL (DBID=2730563515)

What is difference when you issue a create controlfile with "standby" keyword on the primary database
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';
vs. creating a control using
ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';
what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?
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.)
My steps for testing as below:
1.create a primary database
2.duplicate a physical standby database;
3.turn on flashback on both databases.
4.record SCN xxx on physical standby database.
5.convert physical standby to logical standby (using keep identity statement)
6.flashback to logical standby to xxx
7.convert logical standby to physical standby
8.using real time apply I got errors: Fast Parallel Media Recovery enabledManaged Standby Recovery starting Real Time ApplyMRP0:

We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?

I have 2 servers both having windows server 2008 64 bit as operating system installed on both I need to install oracle clusterware 11g r1 on both servers with clustering on external storage. I have configured the network(private,public and virtual) for both servers and have started the installation.
In the installation of oracle I add both servers but then I reach to a point where they ask me for voting disk or ocr disk in the cluster configuration storage but no disk is present how can i create ocr disk or voting disk on windows server 2008? And the external storage should I buy a special type of storage that supports clustering to continue my work?
I'm trying to prepare data guard operation on the virtual machines.
1. I have install Oracle database without start up database on the standby server.
2. I try to connect this db by sysdba, but failed!

I have an issue whereby our standby instance was down for a couple of days and when it came back online we found an archivelog file was missing, so recovery only happened up to a point. It appears that the archivelog was deleted therefore we are unable to continue with this standby. We are now planning to rebuild the standby database. As far as i know all of the steps originally performed need not be performed to complete this task.
1. Shutdown standby
2. Delete all datafiles & redo logs
3. Copy over datafiles to respective directories
4. Copy online logs and archivelogs to standby.
5. Create a control file for standby database
6. Startup mount standby database
7. start redo apply

I would like to configure a logical standby using oracle 9i...Is it possible in 9i?
Difference between standby and dataguard. I assume standby and dataguard are same?
View 4 Replies View RelatedWe are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.
The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.
Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.
