Logical Standby on Standard Edition

Hey,
I have to setup an enviroment with 10gR2 on Linux.
I can only use standard edition.
I will have a manual physical standby in place.
Now I get a new requirement: I need to have an additional db for read only access.
Now logical standby is not possible with standard edition.
I found shareplex for oracle (quest) - would that be an alternative ?
Do you have other ideas how to realize an standby database which can be read by an application -- the database should be sync with the primary as possible
thx

It is possible to setup a schedule for your standby database to switch between READ ONLY mode and recovery mode.
For example, from 8am till 12pm, you can have your physical standby database be in read only mode, so that users can run reports. The standby database will not be updated during this time.
From 12pm till 2pm, the standby is switched to normal recovery mode and all the latest changes are applied.
At 2pm the standby is switched back into read only mode for reporting purposes.
At 6pm the standby database is put back into recovery mode until 8am the next morning to ensure the standby database is fully up to date for the next reporting day.
For this to work well, and to make sure you are also covered for DR at all times, it is important that your primary database keeps sending the archive redo logs to the standby server.
The archive redo logs are then queued up and ready to be applied on the standby server. So if you do suffer a major outage and have to activate the standby database, all the archive logs are available on the standby server.
This is how http://www.dbvisit.com works to enable physical standby for Standard Edition (SE).

Manual Standby on Standard Edition

Hey, I try to setup a manual standby on standard edition 10gR2.
Source is a RAC database (standard edition on sles10 sp3)
I created a node and created a oracle instance on this node. This node is using the filesystem for the oracle files.
I did a hotbackup of the source database and copied all files over to the other host.
Which parameters needs to be change in the init.ora and how can I recover my database ?
Articles like
http://www.databasejournal.com/features/oracle/article.php/3682421/Manual-Standby-Database-under-Oracle-Standard-Edition.htm

ORACLE 8I: STANDBY DATABASE는 STANDARD와 ENTERPRISE EDITION에서 사용이 가능한가?
=====================================================================
Problem Description
원격의 Standby 데이터베이스 구성을 고려하지만, standby 사이트로
고려하는 장비에는 Oracle8i Standard Edition이 동작을 하고 있는 반면
primary 사이트에는 Oracle8i Enterprise Edition이 동작을 하고 있다.
이러한 경우 다음의 질문을 하게 된다:
Primary 사이트에서는 Oracle8i Enterprise Edition을 standby 사이트에서는
Oracle8i Standard Edition을 사용하는 것은 가능한가?
Oracle8i Standard Edition database가 Standby 모드로 동작을 하면서
Oracle8i Enterprise Edition database의 log들을 유효하게 받아들일 수
있는가?
Solution Description:
Basic Standby 데이터베이스 기능은 Oracle7,Release 7.3.x, Oracle8, 그리고
Oracle8i Standard Edition에서 사용이 가능하다.
Enterprise Edition과 Standard Edition 모두 Standby 데이터베이스 기능을
사용하기 위하여 구성할 수 있다. 그렇지만, Non-managed Standby 환경에서
Stabdby 데이터베이스에 적용하여 복구를 하기 위한 추가적인 작업이 필요하다.
a) Standby 데이터베이스 상에서 수동 또는 스크립트에 의한 복구가 필요하다.
b) 저장되어진 Redo Log들을 Standby 사이트로 옮기기 위한 방법이 필요하다.
Explanation:
===========
Standard edition에서 사용할 수 없는 Standby 데이터베이스 특징의 유일한 점은
Log의 원격 이동 능력이다. 다시말하면, Oracle8i의 Log 원격 이동 기능은
Enterprise Edition에만 있는 특징중의 하나이다. 이 이외의 Standby 데이터베이스
특징들은 Oracle8i Standard Edition이나 Oracle8i Enterprise Editio 모두
동일하다.
자동 Log 이동은 Managed Standby 환경으로 Standby 데이터베이스를 운영하기
위해서 필요하다.

Logical Standby & Primary site Time Diiference

Hi,
I have the one primary site over RAC configuration and one Logical standby

know, how can we compute the time difference between Primary Site and Logical
Site ex. IF suppose some SCN XYZ is applying on logical standby site so when
the same SCN (XYZ) generate (time) on the primary site. We need exact time
difference between Primary site and Logical Site.
If there is any query or other method pls suggest to find out this information.

How to create physical standby database without dataguard

Creating standby database from ASM production database in standard edition

Hi,
I am using oracle 10g release 2 standard edition. I recently created a database instance and wanted to create a standby database instance. After sorting out how to achieve this without managed standby and data guard I finally got it working and the shipped archive logs are applied and working well on the standby database.
Now I am thinking of re-creating my production database and using ASM for storage managment. By doing this can a standby database still be created from a primary database using ASM? I want to be sure I can before I commit to using ASM for the production instance and manually creating a standby database from that instance.
Note: I am using standard edition not enterprise edition.

Hi
For Oracle SE standby, you can visit www.anbultechnologies.co.uk , they have a brilliant product name DRMC which is Automatic disaster recovery solution with automatic failover in case primary goes down due to any reason.
We are using this product for more than 2 years and it works like a dream using Oracle Standard Edition. We have depolyed more databases and Standby solution within the prices of 2 EE edition licenses.
You can give ma try as well.

Standby implementation in Standard Edition

To All,
I am Ashok(DBA) from Nepal. My country is a developing country and cannot afford Oracle Entreprise Edition in most of the instuations.
So I need to implement Standby database in Oracle Standard Edition. I need this feature both in Windows and Unix based platform.
I will be grateful if suggestions come on implementing this feature in Standard edition.

Hi!
1) This is the wrong forum (try the Database forum).
2) Yes, Oracle software is expensive.
3) In order to use the DataGuard (Standby database) you need the Enterprise Edition.
4) Workaround is to export / import regularly and use XE.

Standby DB on Standard Edition

Hi,
I've just created standby database using Oracle DBMS 10.2.0.2 Standard Edition on IBM AIX 5L. Because it's Standard Edition, I had to use a operating system scripts for log shipping and log apply operations. My log apply script looks like that:
#!/bin/sh
export ORACLE_SID=ORCL
sqlplus "/ as sysdba" <<EOF
set echo on
spool /oracle/standby/logs/logapply_ORCL.log
alter database recover automatic standby database until cancel;
alter database recover cancel;
spool off
EOF
in the logapply_ORCL.log file i always find a message like that listed below:
SQL> alter database recover automatic standby database until cancel;
alter database recover automatic standby database until cancel
ERROR at line 1:

Additional information: 3
SQL> alter database recover cancel;
Database altered.

I know that this error is ok, and it means that Oracle couldn't find file which probably doesn't exist. Is it possible to have that information more friendly or presented in more pleasant way?
Thanks,
Tim

since, you are on unix, you can do anything you want with the logfile. Just cut out the message and replace it with a new one.

Standby Database with Standard Edition

Hi All,
I'm attempting to setup a Standby database with Oracle 10g Standard Edition. I must manually copy over the archive logs to my Standby database server because i'm using Standard Edition.
Once my primary database archive logs have been copied over to the standby location shouldn't the database automatically apply those archive logs? I have issued the "alter database recover managed standby database disconnect from session" so my understanding is that it is in recovery mode and shoudl be finding the archive logs to apply. Can anyone confirm that this configuration should work with Standard Edition and perhaps point me in the right direction, which parameters in the init file to check, to get my standby database to apply these archive logs automatically.
Thanks,

To quickly determine the level of synchronization for the standby database, issue the following query on the physical standby database:
SQL> SELECT ARCHIVED_THREAD#, ARCHIVED_SEQ#, APPLIED_THREAD#, APPLIED_SEQ#
2> FROM V$ARCHIVE_DEST_STATUS;
ARCHIVED_THREAD# ARCHIVED_SEQ# APPLIED_THREAD# APPLIED_SEQ#
1 947 1 945

ASM Direct file access (for creating standby database in Standard Edition)

Hi all,
Just really looking for any opinions, experience etc. that people may have about this.
My company are looking to set up a RAC system. They have also asked me to think about creating a standby database for disaster recovery. The first problem they give me here is that they only pay for Standard Edition of Oracle, therefore Dataguard is not an option.
I know that one can setup "manual" standby databases with Standard Edition, automating the shipping of archive logs with hand-written scripts etc. However, as the primary here is RAC, and will be using ASM on the shared storage, I'm not sure that this would be possible (and I'm even less sure that it would be desirable!). I say this because I don't know of a way to access (using only the O/S and/or Oracle) the database files stored in ASM, and even if there was a way, I can't imagine it being a good idea..
Anybody know of a way to tackle it, or care to contribute anything to this? As I say, my opinion is that even if it is possible to get to those files within ASM and hence manipulate them, I'd be worried that it wouldn't be such a good idea. But I'm willing to bet I'm not the first to have thought about it...
Regards,
Ados
Edit 1:
Sorry, I should state that in principal, the basic environment is:
Windows 2003 Server
Oracle 10g R2
I didn't state that originally though, as I'd be keen to hear from anyone who may have attempted this on any O/S and Oracle version.
Edited by: Ados on 16-sep-2009 9:32
Edit 2:
I also realise we could put the archive logs on the local nodes.. but to reinforce the point, I'm talking about having them on the shared storage where - in theory - the management is easier and more effective.
Edited by: Ados on 16-sep-2009 9:35

For anyone interested..
I guess it would be done using RMAN (in fact, I'm sure of it...) in which case, I feel a lot more comfortable doing it!!
For example:
backup as copy archivelog ALL to destination 'c:\temp\';
This way, it shouldn't matter if the arch logs are stored using ASM, we can now get them and "see" them.. and hence "manipulate" them (pass them on to a standby DB, for example).
I'm just waiting to get my hands on a Standard Edition installation where I can test all this.. To try it all out (with 2-node RAC, and a standby server) I don't think I'll get a chance, so still interested in opinions, or if anyone's actually done this.
Regards,
Ados

Did you have a look at the dataguard docs,
http://docs.oracle.com/cd/E11882_01/server.112/e10700/standby.htm#i72073
Which has this mentioned quite clearly,
>
Oracle Data Guard is available only as a feature of Oracle Database Enterprise Edition. It is not available with Oracle Database Standard Edition.
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>
So if you want to have data guard, use Enterprise Edition.

Archive apply issue for standby database in Standard Edition.

We have setup standby database in Oracle standard edition. the archive log cannot be send by oracle automatically. So we manually send the archive over. But do not see the database apply the archive log file. What could be wrong and where should we check on it?
We also used following when finishing the standby DB after running "recover standby database;" for a few archive log file:
alter database recover managed standby database disconnect from session;
======================================================================================
This is the status:
SQL> select OPEN_MODE, SWITCHOVER# ,REMOTE_ARCHIVE ,ARCHIVELOG_CHANGE#,SWITCHOVER_STATUS, DATABASE_ROLE from v$database;
OPEN_MODE SWITCHOVER# REMOTE_A ARCHIVELOG_CHANGE# SWITCHOVER_STATUS DATABASE_ROLE
MOUNTED 495550636 ENABLED 1.2201E+13 SESSIONS ACTIVE PHYSICAL STANDBY

The DB version is 10.2.0.5
I can do this to apply at standby DB:
SQL> set autorecovery on
SQL> recover standby database;
Then I tried to run this to leave the session:
alter database recover managed standby database disconnect from session;
Do not seen any apply.
