Basic Standby Database(Manually Managed) in Standard edition

Hello,
We are using oracle SE where dataguard feature is not available. So we cloned the database and applied archived logs for recovery followed a metalink doc. Everything is good. Now I need to keep my standby in synch with primary, for this i need to manually transfer all the archived logs from primary to standby arch dest location. So any idea as this is a manual process which we cant scp daily...so do we have any script that we can set up in cron to scp the archive logs once during a particular time and then delete them after applying at standby? or else please tell any better idea if you have. Appreciate any help.
Thanks
kumar

Hello;
It might be simpler to use 'rsync'
rsync -e ssh -Pazv /ora/oracle/arch/ oracle@remote:/export/home/oracle/arch/
There's an example here :
http://www.databasejournal.com/features/oracle/article.php/3682421/Manual-Standby-Database-under-Oracle-Standard-Edition.htm
I use rsync for similar things like when I want to move a group of files without listing them.

Basic standby database configuration in Oracle10g standard edition

Have anyone successfully implemented the technology in Oracle8i and earlier known as "Basic standby database" in Oracle10g SE? From the information, that I've been able to gather, this technology still exists in Oracle9i and later, along with Oracle Data Guard.
I'm not interested in the complete Data Guard environment - only the standby database feature as mentioned above. Basci
I've tried the documentation regarding the configuration of Data Guard (in lack off precise documentation on this technology) - but it's very confusing what's possible on SE an EE editions.
I've followed all the guidelines, enabled archive logging on primary database, created standby control file, copied the primary database files, created the pfile from the primary database - and then used this as the source for the spfile on the standby database.
I can then mount the standby database and start the recovery process with the following command:
alter database recover standby database disconnect;
The database is altered but no archive is applied (I've manually copied the archive logs from the primary). I've configured the standby_archive_dest - but the status for the MRP0 process keeps saying: WAITING_FOR_LOG
It seems like the "automatic" recovery mode doesn't work on SE. My conclusion is that you'll have to do everything manually - which means that I've have run the recover command manually - everytime I want to apply the archive logs from the primary.
Does anyone have a complete how-to-guide on this issue or have tried implementing in a real solution?

Hi,
>>The database is altered but no archive is applied (I've manually copied the archive logs from the primary). I've configured the standby_archive_dest - but the status for the MRP0 process keeps saying: WAITING_FOR_LOG
because ur using standard edition and in this edition the archivelog will not automatically move to standby from primary database.so u have to automatically transfer and apply it.

How to create physical standby database without dataguard

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

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.

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.

Creating standby or logical standby database manually?

Hi,
I have to create 4 logical standby databases on a Linux Red Hat 64-bits server.
The primary databases reside on another Linux Red Hat 64-bits server.
The oracle database version is 10.2.0.3.
The question is as follows:
Should I create the logical standby databases manually or should I do it with the Oracle EM Grid Control?
I have read that the creation of standby databases with the Grid Control is very straightforward, but I really want to read of some of your experiences.
I have read that there are some problems in Grid Control with the test of Failover and Switchover.
Please advice.

Hi,
It all depends.
I assume you don't backup your database to tape using RMAN.
Do you backup your database to disk using RMAN?
You would need to set up NFS links from your standby server to the primary server.
For this purpose, in 9i, I made sure my disk backup ended up in <directory>/backup/<nodename>, so I could easily set up a NFS link.
If you do it manually, you need to have made a full database RMAN backup first.
Probably Grid Control is taking care of this for you.
I have done it once using database control in 10g. It is really simple, and you just have to click a few buttons and sit back.
Doing it manually is slightly more work: you need to make sure parameters are correct and you need to write a (generic) script of less than 10 lines.
You probably do have more control over it, though RMAN's duplicate database command is robust and can be restarted easily.
I can't answer your last remark.

Database link between Oracle Standard Edition and Oracle Enterprise Edition

Hi,
I am looking at setting up a data transfer process between an Oracle 11g Enterprise Edition database and an Oracle 11g Standard Edition database. Database links would be required each way.
I heard once that this is not permitted as connecting Standard to Enterprise via a DB Link means that the Standard Edition database would now need an Enterprise license.
I have searched around but can't find anything to confirm this. Am I being mislead by this information? Is it permitted to
connect Standard to Enterprise via a DB Link?

When a db-1 has a link pointing to db-2, as far as db-2 is concerned db-1 is just another client .. no different than sqlplus. If you have an Enterprise Edition database, of course it will need to be properly licensed. But that doesn't mean all of its clients (including a SE database) have to be EE licensed.
But even my reply is just something you read on the internet. Licensing questions can only be definitively answered by Oracle itself. Ultimately you will need to put your hands on an official Oracle document or a written statement from someone authorized to make such statements.

Dataguard with 11g Standard Edition

Hi, We have 11g standard edition. I wish to provide high availability. From the license document We are able to setup Basic Standby Database(Manually Managed). What is difference between Data guard and Basic standby? Hw can i configure? What r all the requirements? Any other possible ways?

Thanks. That document is very useful for me. That document contains Version: 8.1.7.4 to 10.2. But i have 11g. Is this applicable for 11g also.

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#

Creating Standby database with Oracle 10gR2 SE (no dataguard). Procedure

Hello,
I have problems in creating a standby database without Dataguard (Oracle Standard Edition)
-Oracle 10gR2 SE (No DataGuard !!!!)
- SUSE Enterprise 10.
Both primary and standby databases are running in Virtual machines (lab).
I will describe the exact steps I followed :
1.---------------------------------------------------
Both primary and standby databases have exactly the same file / folder structure
2.---------------------------------------------------
I enabled archive log mode with a new destination : /opt/oracle/oradata/orcl/archive_logs.
Also : SQL> alter database force logging;
3.---------------------------------------------------
I shut down the primary database (shutdown immediate)
4.---------------------------------------------------
I created a standby controlfile on the primary database:
SQL> startup mount
SQL> alter database create standby controlfile as '/tmp/standby.ctl'
SQL> shutdown immediate
5.---------------------------------------------------
I did a cold backup from the primary db to the standby db
(I copied all the db files, control files, redo log)
6.---------------------------------------------------
I copied from the primary db to the standby db the standby control file
(from primary /tmp/standby.ctl)
7.---------------------------------------------------
I copied from the primary db to the standby db the standby control file
(from primary /tmp/standby.ctl)
8.---------------------------------------------------
I created on the standby database a pfile from the spfile :
SQL> create pfile from spfile;
9.---------------------------------------------------
I edited the pfile and changed the controlfile location (with the standby controlfile created in step 4)
>>>>> *.control_files='/opt/oracle/oradata/orcl/standby.ctl'
10.--------------------------------------------------
I started the standby db
SQL> startup mount pfile='/opt/oracle/product/10.2/db_1/dbs/initorcl.ora'
SQL> alter database recover managed standby database disconnect from session;
SQL> quit
11.--------------------------------------------------
I made some changes on the primary db on user scott
SQL> update table set .......
12.--------------------------------------------------
I switched logfile on the primary db
SQL> alter system switch logfile;
13.--------------------------------------------------
I manually copied the new archivelog to the standby db
And then nothing !!!
The db changes are not applied.
Please help me fix the procedure !!!
Thanks

Hi
Ref to your Oracle SE Standby issue, we were in similar situation couple of years ago to build an Automated Standby for our disaster recovery on Oracle SE. We finally got a solution provider Anbul Technologies , they have a one of their solutions based on Oracle SE which provided fully automated Standby in Oracle SE.
We are successfully running that solution in our prod env for many years. You can visit their site www.anbultechnologies.co.uk or contact them for further details. They are Uk based but provides support and services all over Europe.

Physical standby database in Standard Edition.

Hi, we have Standard Edition and want to implement a stand by environment. Is it true that with this edition archive logs are not transported automatically to the stand by server using LOG_ARCHIVE_DEST = my_stdby_service ?
Also, let's suposse I managed to transport archive logs, do they get applied by stand by database automatically or with Standard Edition the only way we have is applying them manually?
Thanks and regards.

Hi
Ref to your SE Standby database, if you are still looking for an Automated Solution you can visit www.anbultechnologies.co.uk . In solutions you can find a product which provides fully automated Standby solution with Automatic failover. We have been using that solution for couple of years without any problems.
This solution is based on Oracle Standard Edition and provide functionaility similar to EE data guard.
