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.

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.

Ados

Regrading standby database in standard edition

hi gurus
i m facing problem in configuring standby database in standard edition windows 2008 .
os-windows 2008 standard
oracle 11gr2
i have copied files from primary n copied it to same location on standby...at that time database was in noarchivelog mode
then i made it archive n create standby controlfile...also i have created same service name thru oradim with mentioning pfile and same password as on primary
so it created pfile and password file...
i opened the database in nomount with pfile
then mount with standby controlfile it got mounted n the mode is automatically archivelog mode but as i didn't taken the same pfile of primary it didnt take the destinations as such n made archive in flash recovery area
now i m a bit confused how to apply archive..i copied some archive and placed it in flash rec area
i tried all options managed recovery.recover standby database,recover database until cancel
but all give error
please tell how i proceed..what shud b the right process in standby standard edition
if possible send me a good link for standby database creation in windows 2008 standard with how to ftp files with mget mput..
anyone if kindly provide a good link...wud b of great help
thanks all

on your standby database you can use:
set logsource path_to_archives
This will let Oracle know where the archive files are on the standby database.
Then you can apply the archives with:
recover standby database
Another option is to use Dbvisit Standby to automate the whole standby database (including creation) for you when you have Oracle Standard One or Oracle Standard Edition One.

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.

Dataguard Implementation in Standard Edition

Hi all,
Which third party tool is best for implement the DATAGUARD. Because Oracle dataguard wont support for Standard Edition.
Thanks,
Muthu

Hi,
this sounds like: I have a very important database, which my business is totally dependend on. It needs high availability and reliability - but I don't want to spend money for it.
Sorry... this I really cannot understand....
Also make sure the customer knows the implication of using dbvisit. DBVisit is based on archive redologs (same as manual standby mechanism). So he will definitely loose some transactions in failover case.
There is no Zero Data Loss.
Furthermore make sure you are not using STANDBY_FILE_MANAGEMENT set to auto. This is Enterprise Edition functionality.
I personally would look on other options to save costs: Like using an Oracle database appliance, where I can reduce license costs by disabling cores. This may enable the customer to use EE (with only minor investment).

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:

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

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.

Oracle manually standby database with standard edition

Hi, I want to have a plan for disaster. I'm triying with two virtual machines with oracle database 10g on suse linux. I follow these URLs
http://www.dbasupport.com/oracle/ora10g/manual_standby.shtml
http://oramdq.blogspot.com/2009/05/como-configurar-un-sistema-de-alta.html
and it look that work all right.
I know that with manually standby database we applied archived logs, and so, we don't propagate any physical changes to secondary database (standby), for example, if I create a new tablespace, or adding a new datafile to an existing tablespace, it don't work in the secondary database.
Anyone does know how is the better way to apply the physical changes??
Anyone have any scripts to do that?
Thanks in advance.

HI,
Add the STANDBY_FILE_MANAGEMENT = AUTO to the primary parameter file, it will solve it.

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
or

Thanks for your patience... :-)

./rman target / cmdfile=/opt/oracle/rman.sh

Standby synchronization in 11g Standard Edition.

I have the following environment: one primary DB and one standby DB (both 11g Standard).
I have to synchronize standby with primary but in Standard edition I can not use automatic mechanism.
I don’t want to use commercial staff like Pervasync.
How can I achieve this? May I e.g. generate archive and/or control files, next “manually” send and put these to standby?

Implementing replication in Oracle 10&11 Standard Edition

I am implementing an oracle based application which will run under Linux/Oracle 10gr2 standard edition and which will soon be upgraded to Oracle 11g standard edition.
One of the requirements of the application is that a hot standby must be provided. To provide the hot standby, I must implement some sort of replication mechanism, but the nice replication features (data guard, streams, advanced replication, basic replication) are only available with Oracle enterprise edition.
Two questions:
1. It appears that I will be building a home-made replication mechanisms. I am planning on using insert/update/delete triggers and dblinks to trap database updates and propogate them to the standby server. (alternatively, may write them to files as SQL statements and have the second server load the files). Is their a better way to implement replication in Oracle SE. (esp. a feature of Oracle SE that I could be using to do this?).
2. Oracle Advanced and Basic Replication are not shown in the Oracle 11 Editions Description web page which lists the availability of features across the various oracle versions. I assume it is still supported in Oracle 11, but is Oracle Streams now the "best practice" for implementing replication (i.e. instead of advanced replication?)
Thanks in advance,
Werner

1) Having database triggers that use a database link is an exceptionally poor way of implementing a hot standby. If the database link goes down, or if the remote database is unavailable, the trigger will generate an exception and the parent transaction will be rolled back. Which means that the system is available only if both databases are available and the network between them is available, which is exactly the opposite of what a hot standby would be expected to provide.
2) You most likely want to set up a manual DataGuard-like setup. Clone the database from one machine to another, keep the standby database in managed recovery mode, and copy archived log files from the primary to the standby periodically. You'll have to script that, of course, but that shouldn't be insurmountable.
3) Basic replication (one-way materialized views) are available in the standard edition, but probably aren't the sort of thing you'd want to use to build a hot standby.

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
