How i create Standby Database in Same HOST, we using SUN OS 5.8.
I read form Oracle DOC that i can create Standby Database in Same HOST and follow the tutorial , but when i try to mount standby database using ALTER DATABASE MOUNT STANDBY DATABASE EXCLUSIVE; i got a error message ORA-01102: cannot mount database in EXCLUSIVE mode
I performed Shutdown Immediate in Oracle 8I and now I am unable to mount the database.I'm getting the following message: ORA-01102 Cannot mount database in Exclusive mode/I only have one database running on this machine. It was automatically created by Oracle installer upon installation of Oracle software. I can no longer connect via SQL * Plus,Only through Server Manager (connect internal)
View 8 Replies View RelatedI'm trying to create a physical standby database on my Oracle9i DB runing on WinXP.
Note: I have both Primary and Standby on the same system.
Actually everything went well .... I did created the standby DB but the problem is I can not start my primary DB if my standby DB is mounted. I get this error:
ORA-01102: cannot mount database in EXCLUSIVE mode
And when I read about the error message I learnt that I should start my DB in compatible mode ...
I am trying to create the Physical StandBy Database in the same server. Till last 2 Final steps, everything went on well. In the final steps, when I try to open the StandBy Database, it throws the following Error:
*******************************************************
SQL...> alter database open;
alter database open
*
ERROR at line 1:
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
*******************************************************
I tried creating the Physical Standby with the following Steps.
Environment: Oracle Release 10.2.0.1.0 / Windows 2003 Server Enterprise Edition SP2
Primary DB = 'PrimDB'
StandBy DB to be created ='StBy1DB'
In the same Server, location for
PrimDB datafiles='F:oracleproduct10.2.0oradataPrimDBData',
StandBy Datafiles='E:StandBy_DBData'
PrimDB Control Files='F:oracleproduct10.2.0oradataPrimDBControl'
StandBy Control Files= 'E:StandBy_DBControl'
[code]....
Step 1 Create the Oracle Service for StandBy DB "StBy1DB' and Create the Standy DB Password file.
ORADIM -NEW -sid StBy1DB -intpwd passwd -startmode manual
Step 2 Shut down the primary database.
SQL> SHUTDOWN IMMEDIATE;
Step 3 Copy the datafiles to 'E:StandBy_DBData'. (including Temp01.dbf is it Right?)
Step 4 Restart the primary database.
Restart the primary database:
SQL> STARTUP;
Step 5 Create a Control File for the Standby Database (Should this command be given in Mount Status or Open Status?)
From Primary database,
SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'E:StandBy_DBControlStByControl01.ctl';
Step 6 Prepare the Initialization Parameter File to be Copied to the Standby Database
SQL> CREATE PFILE='E:StandBy_DBPFileinitStBy1DB.ora' FROM SPFILE;
Step 7 Set Initialization Parameters on a Physical Standby Database
db_cache_size=444596224
java_pool_size=4194304
large_pool_size=4194304
shared_pool_size=150994944
streams_pool_size=0
[code]....
Now When I type the following command, it throws an error:
SQL...> alter database open;
alter database open

ERROR at line 1:
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
which commands only we can use in database mount mode?

View 6 Replies View RelatedI have few queries regarding standby database.
1)On primary Database Standby Redo log is required for switchover and on standby database Standby Redo log is required for
--Real time Apply
--Maximum protection or Maximum availability
Am I correct?
2)My database is in Maximum Performance mode. I set up following entry on init.ora:
LOG_ARCHIVE_DEST_2='service=standby LGWR ASYNC'. My question is do I need to have STANDBY Redo log file on standby database in order to use LGWR transport (LGWR ASYNC)mode from primary? Without Standby redo log on standby database can it transport redo data from primary to standby using LGWR transport mode (LGWR ASYNC)?
3)I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode. I would like to know whether is there any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?
1) If i do changes in table on primary database and if i open standby database in Read-Only mode, i can see those changes immediately only if Real Time Apply is enabled. Am i correct? Database version is 10.2.0.4
2) From 11g, It is possible to apply redo while the standby is open in read only mode. prior to 11g, it was not possible. Right?
3) Should I first cancel Managed Recovery prior to issuing “ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY”?
Controlling User Access to Tables in a Logical Standby Database can be controlled using the following command:
ALTER DATABASE GUARD STANDBY;
My simple question is: how can I know the current active Guard setting in the standby database?
Oracle 11g R2.
While I was trying to configure an Oracle DB called "NW6" using the Database Configuration Assistant, I have Oracle 11.2 database installed on a Windows 2008 Server, the configuration wizard thrown an error : ORA-01507:database not mounted
So I am not able to successfully complete the DB configuration. Also I tried to test the service using the net configuration assistant, it throws an error: ORA-27101 shared memory realm does not exist.
I recovered dbf and ctl files, how to mount that database again. Using oracle 9i.
View 1 Replies View RelatedI 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 have a clients who currently implementing an application that using Oracle 10g in 20 distributed location. Each location will have its own database server and locally managed. I plan to create a Disaster Recovery (DR) Centre for this client in centralised location. I plan to setup 20 Application Server but only one database server with 20 instances. My question, can the Dataguard manage the replication between 20 database (with single instances) and single database (with 20 instances? The reason we design such way is to reduce the license cost of Oracle.

We are a small business and growing at rapid rate. we want to cut down the cost at the same time.

I am planning to use Data Guard facility in Oracle 10g database.
1) I would like to have a standby database, which can be used if the primary goes down and also for reporting and other queries (read-Only).
2) What is the difference between Physical and Logical standby database. I have to explain non-technical users (management) regarding this.
3) What is Sync and Async redo log apply?
4) When i manipulate data (Insert,Delete,Update) in logical standby database, will these changes reflect in Primary database synchronously?
5) Which type of REDO APPLY is better: Managed Recovery Process(MRP) or Real Time Apply(RTA)?
6) can the redo data be deleted if its obsolete or is it deleted automatically by oracle?
7) If i want to take backup, should i take it from primary or standby database? If standby, then the database should be in which mode (Read-only or Recovery Mode)
Oracle RDBMS 11.2.0.2 on RHEL 5.6.
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.
