(V7.3) STANDBY DATABASE IN ORACLE 7.3

제품 : ORACLE SERVER
작성날짜 : 2004-08-13
SCOPE
Standard Edition 에서는 standby, data guard 기능은 지원하지 않으며, 이 기능을 대체하는 Oracle Fail Safe 는 Oracle 8.1.6 이상 부터 지원이 됩니다.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Standby database에 대하여
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. 오라클 7.3 버젼에 추가된 new feature 로서 archive log mode 상태에서
online tablespace backup이 필요없는 새로운 backup/recovery 방법이다.
즉, archive log mode에서도 각 tablespace의 주기적인 online backup이
필요하였고, 이 작업에 따라 회복시간이 좌우되었다. Standby database를 잘 유지
하여줄 수 있는 환경이라면, online tablespace backup 대신 유용하게 사용될 수
있다.
2. 회복 시간은 작업량과 standby database에 archive log file이 어느 정도
반영되었느냐에 따라 다르다.
3. OPS와의 비교
instance를 두개 이상 사용하는 Oracle Parallel Server와 비교하는 것보다
위의 1번에서 소개한 환경과 비교하는 것이 더 적절하다.
4. 생성 방법
4.1 create the standby database
; standby db의 생성
1) back up the datafiles
2) startup mount;
alter database create standby controlfile as 'filename';
3) alter system archive log current;
4) transfer backup-datafile, archived log files, standby controlfile
to the safe place for standby database.
4.2 maintain the standby database
; log file을 standby db에 적용시켜 최신의 데이타로 유지함.
1) startup nomount;
2) alter database mount standby database;
3) recover standby database ;
4.3 activate the standby database
; primary database가 정상적으로 startup할 수 없을 때
1) alter database activate standby database;
!!! 일단 standby database를 기동시켰으면, 이전의 stand by database
상태로 되돌릴 수 없으니 신중하게 사용하여야 함.

I haven't done a Snapshot Standby (RAC or non-RAC). But I see no reason why it shouldn't work with a RAC Standby either.
The command is a Database level command, not an Instance level command.

Creation of Standby Database on Oracle 10g Standard Edition

Hi Gurus,
Can anyone let me know how to create physical standby database on Oracle 10.2.0.1(Standard Edition). I am using the Fedora7(32-bit) machine. Can anyone please send me some documentation on how to create.
Thanks in advance.

How to create physical standby database without dataguard

Can i create a standby database in oracle 10g standared edition ?

what are the steps required for creating a standby database using oracle 10g standard edition. or Any other feature for mirroring database in oracle 10g standared edition

Dear mithun,
Please read the following online documentation;
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/standby.htm
+"+
+2.3.2 Oracle Software Requirements+
+The following list describes Oracle software requirements for using Data Guard:+
+* Oracle Data Guard is available only as a feature of Oracle Database Enterprise Edition. It is not available with Oracle Database Standard Edition. This means the same release of Oracle Database Enterprise Edition must be installed on the primary database and all standby databases in a Data Guard configuration.+
+Note:+
+It is possible to simulate a standby database environment with databases running Oracle Database Standard Edition. You can do this by manually transferring archived redo log files using an operating system copy utility or using custom scripts that periodically send archived redo log files from one database to the other. The consequence is that this configuration does not provide the ease-of-use, manageability, performance, and disaster-recovery capabilities available with Data Guard.+

Hope That Helps.

Create an Object in Logical standby database in Oracle 10G

Hi,
I have logical standby database in oracle 10g R2 for reporting purpose.Now i want to create procedure in logical standby which is use to create new temp table in logical standby and contained data generated from select operation on existing table.
Can i create a new user in logical standby database,add new tablespace in logical standby which can insert,update and delete data in standby database base table?
kindly provide me the steps to implement all this.What will be effect if i set guard_Status in v$database is NONE in logical standby?
Thanks,
Shital Patel

Hi Shital,
Guard_status protects the data from being changed.
ALL- By default it is not possible for a non-privileged user to modify data on a data guard SQL apply database. This is because the database guard is automatically set to ALL.
With this level of security, only SYS user can modify the data.
STANDBY- When you set this level of security, users are able to modify data that is not maintained by the Logical apply engine.
NONE permits any users to access the standby database as long as they have correct privileges. This is the normal security for all data in the database.
You can change the guard status value from ALL to NONE in order to allow non-privileged users to modify data and Yes you can create user and extra tablespace in logical standby database..this is what the one of advantage of using Logical standby database.
SQL> ALTER DATABASE GUARD NONE;
Thanks

To create standby database using oracle 10g standared edition

my producation database is oracle 10G standard edition .Can i implement a oracle dataguard or standby database using standard edition licenses.if standby database is possiable in standard edition .what are the steps for creating a standby database using oracle 10g standard edition.

General answer is http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABJICBB.
For Data Guard you cannot :
- use instance parameters to automatically send archived redo logs
- use instance parameters to resolve archived redo logs gaps
- create a logical standby
- use SQL statements to do switchover / failover
- use Data Guard Broker.

Hello;
Generally for the connection to work you need to add something like this to the listener.ora file :
(SID_DESC =
    (global_dbname = STANDBY.hostname)
    (ORACLE_HOME = /u01/app/oracle/product/11.2.0.2)
    (sid_name = STANDBY)
)You should stop and start the listener on the Standby after adding this. Also your tnsnames.ora must be correct on both the primary and the Standby.
Also you need an INIT for the Standby side :
STANDBY.__db_cache_size=343932928

Keys to success

3. Correct tnsnames.ora files.
4. Correct duplicate command.

Can anyone suggest what could be the reason behind this?

Dear user13295317,
Here is the error explanation;
Oracle Error :: TNS-12533
TNS:illegal ADDRESS parameters
Cause
An illegal set of protocol adapter parameters was specified.
In some cases, this error is returned when a connection cannot be made to the protocol transport.
Action
Verify that the destination can be reached using the specified protocol.
Check the parameters within the ADDRESS section of TNSNAMES.ORA.
Legal ADDRESS parameter formats may be found in the Oracle operating system specific documentation for your platform.
Protocols that resolve names at the transport layer (such as DECnet object names) are vulnerable to this error if not properly configured or names are misspelled.Hope That Helps.

Snapshot standby database in oracle 11g r2 RAC

Folks,
i am just wondering if the process is same for standalone and RAC snapshot standby database.
We have a DR test
1 / I just converted the standalone DR on 11g to snapshot standby database for users to do some testing and reverted back to physical standby after test was done. i folllowed metalink note ID 443720.1
2/ now there is anotherDR test where we have 2 node prod and 2 node DR on oracle 11g rel2 RAC, so not sure we can follow the same process that i used for 11g standalone database. If somebody have done this on RAC, would you please provide the steps ?
Thanks in advance

Standby Database on Oracle 10g Standard Edition ?

Hi All,
Is it possible to do Oracle Stand By Database on Oracle 10g SE ?
I read somewhere in this group that we can do standby database even in SE by writing a script that copy the archive log to the secondary server.
Is this approach reliable enough to be done in production ?
Does anybody have sample of the script ?
Thank you for your help,
xtanto

Hi,
Well, I think I'd beter put the scripts right there. Remember, they have been tested under MY environment, using MY releases, MY O.Ses. It's up to you to check whether the're valid for you. They are provided as is, for sample.
There are 4 files:
. generic.sh : you can duplicate this file in order to set up as many standby as needed, etc. It calls other scripts in order to:
. archivemove.sh : Get the archived redo logs to the standby host
. recover.sh : Synch the standby
. getrecid.sql : get the maximum progess point on the Manual Standby (used by archivemove.sh)
These scripts are used from the standby host. Remember to throughly check it before relying on it for production.
generic.sh
#!/bin/sh
# Be sure environment variable are set. If not, then it might fail!
# These environment variables are those for the Manual Physical Standby host

Standby Database with Oracle Standard Edition

Hi,
my customer wants to create a standby database for his production database (Oracle Standard Edition 11g R2 @ Windows 2008 R2 64 Bit). Now has somebody a proof-of-concept which explains shortly the concept and how to achieve it.
Many thanks in advance.
Best Regards,
Martin

Hi
We have the following options :
1. Oracle Enterprise Edition (EE) - Will have automatically 'Oracle DataGuard' option. No extra license for Oracle DataGuard. We have to purchase Oracle EE for both the sites.
2. Oracle Standard Edition (SE) - Will not have 'Oracle DataGuard' option. So we can't implement Standby database.
3. Oracle Standard Edition (SE) - Will not have 'Oracle DataGuard' option. If you want to implement disaster recovery site we have to purchase Oracle GoldenGate for both the sites. But we have to Oracle GoldenGate license for both the sites
Thanks

Standby Database for Oracle 8.1.7 Std Ed

Hi, I am using Oracle 8.1.7 std ed with W2K Adv Server. Both primary host and remote host using the same version of oracle and OS.
So far both oracle path are identical and the standby folder is same with primary and I don't think I need to add the db_name_convert and log_name_convert into my standby parameter file.
I have make a consistent backup from primary to standby and also create the standby control file from primary. However, I am having the problem on setting up the tnsnames.ora and listener.ora for both primary and standby? Can someone here give me the sample on configure those ora file? Say example
Host Name (Primary) : PRMY
DB_NAME (Primary) : PRMY
SID (Primary) : PRMY
Instance (Primary) : PRMY
Host Name (Primary) : STBY
DB_NAME : PRMY
SID (Primary) : STBY
Instance (Primary) : STBY.
This error message is once i am going to connect the standby database via SQL*Plus using sys/change_on_install@STBY, error ORA-12154: TNS:could not resolve service name displayed. However, I managed to login follow by set oracle_sid=STBY and connect as sysdba.
