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.

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.

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.

Mirroring in Oracle10g Standard Edition

Hello
We have Oracle10g Standard Edition databases in our production server , Now we gonna create a mirror databases for them
Considering that Oracle10g Standard Edition doesn't support Data Guard and Multi-master Replication,
what is your suggested solution for us to creating mirror databases ?
thanks

What is your idea about this solution , for creating mirror database in oracle 10g standard edition
1- we can move full backup of primary database to backup site
2- and then after that we move archive logs from primary site to backup site (we always create incremental backups but we don't want move incremental backups we just want move archive logs)
3- we restore the full backup in backup site and set it in mount state (not open) , every time that we move archive logs then we recover them
4 - we don't open that database in backup site until a crash happened
Do you thing this method is better that standby database method ? why ?
Can moving archive logs only (after sending full backup to backup site) with out incremental backups cause trouble ?
thank you

Standby Database Configuration with LGWR and ASYNC

Hi,
I am running a standby database configuration on a 100MBit LAN
with the following set-up:
log_archive_dest_2='service=standby mandatory reopen=300 lgwr
async=2000'
The system is handling a lot of very small transactions, not
involving large amounts of data.
My questions are:
- What are the potential problems in using a small ASYNC buffer
like the one above?
- Does a larger ASYNC buffer influence the latency in copying
changes from the production database to the standby database -
will it buffer more changes before sending them to the standby
database?

Murlib,
I have few more doubt-
Our requirement is to configure a Standby( Physical-MAXIMUM PERFORMANCE
mode) in a place, which is 600 KM away from our primary destination.
Currently our LAN network traffic rate is 100 Mbps. but this traffic is
virtually reduced to 1Mbps out side our LAN.
Our Production Database is 24X7 and Its generating 17 GB Archive files every
day.
Since the net work traffic is slow i think, it will create some log gaps,and
also we couldn't do a point in time recovery.
We are configuring a Standby, here inside our LAN in Managed Recovery Mode
for recovery purpose and will keep a Standby there in remote place for
Reports.
and it will be recover it in every morning.If iam following this procedure,
my
log_archive_dest_2 ='service=stby ARCH NOAFFIRM' ( which is the standby here
inside our LAN and should be in MANAGED RECOVERY mode)
and i need to configure the parameters for standby in my remote location.So
my doubt is-
Shall i need to configure "log_archive_dest_n" in the parameterlist of my
Primary for that remote Standby ?
I think for manual recovery we can aviod that.But we need to eonnect it
thrrough Oracle Net
Can you please tell me the essential PRIMARY parameter list entries for this
kind of remote standby , recovering in a manual mode ?
i think the following parameter should be there -
FAL_SERVER
FAL_CLIENT
DB_FILE_NAME_CONVERT
LOG_FILE_NAME_CONVERT
STANDBY_FILE_MANAGEMENT=AUTO
STANDBY_ARCHIVE_DEST
Thanks and Regards,
Raj

How will you find out no of standby databases configured for primary database from OS level

How can find the number of standby databases configured for primary database from os level

Check the alert log.
The Alert log will always have Data Guard messages in it.
Example
cd /u01/app/oracle/diag/rdbms/primary/PRIMARY/trace
tail -1700 alert_PRIMARY.log | more
Wed Nov 13 13:35:26 2013
ARC7: Standby redo logfile selected for thread 1 sequence 1164 for destination LOG_ARCHIVE_DEST_2
LNS: Standby redo logfile selected for thread 1 sequence 1165 for destination LOG_ARCHIVE_DEST_2
If you don't see messages like this it's probably not a Data Guard system.
Or search it for :
System parameters with non-default values:
Which on Data Guard system will show things like:
log_archive_dest_1 = "LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=PRIMARY"
log_archive_dest_2 = "SERVICE=STANDBY LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=STANDBY"
log_archive_dest_state_1 = "ENABLE"
log_archive_dest_state_2 = "ENABLE"
fal_server = "STANDBY"

Can standby database configured on VMWare server or not?

HI all,
Is it possible that our primary server is not on vmware server but standby server can be configured on VMWare server?
AFAIK, configuration of both the server should be same.
If our Primary server is not on Vmware server but standby database configured on Vmware server, Will it work or not.
Pls suggest me.....
And another thing is that Is it necessary to have a dedicated connection b/w primary and standby server for RFS process.
pls suggest me....

If our Primary server is not on Vmware server but standby database configured on Vmware server, Will it work or not.Logically speaking, it should not matter but YMMV.
And another thing is that Is it necessary to have a dedicated connection b/w primary and standby server for RFS process.what is RFS process? Could you elaborate?

SCN can be differ in standby and it can be behind to primary based on the backup you have restored. Of course by performing recovery you can synchronize standby with primary database. You can use incremental backups for standby using link http://www.oracle-ckpt.com/rman-incremental-backups-to-roll-forward-a-physical-standby-database-2/

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.

How to remove logical standby database configuration cleanly

Hello,
We are on RHL with 11.2.0.3 DB version. Due to various unknown reasons we would like to recreate logical standby database and for that purpose I would like to cleanly remove/uninstall/drop LOGICAL STANDBY DATABASE from the DATA GUARD configuration we have.
The DG setup already has 1 PHYSICAL STANDBY DATABASE which is working fine. PRIM,PHYSICAL, and LOGICAL all are on different HOSTS. Could you please guide or suggest us exact MOS Doc id regarding this? I have found one MOS Doc id which is close enough but its steps include removing dg configuration completely which I don't want. Only Logical Standby database needs to be remove cleanly so that it can be installed again properly.
We are using GRID CONTROL and DATA GUARD BROKER.
Bundle of thanks in advance.
Best Regards
