SID NAME FOR PRODUCTION & STANDBY DATABASE IN DATA GUARD

Hi all,
we are trying to implement Standby database (Physical) between two
sites. We have a specific question regarding this:
==> Can we have SID of both the Database SAME..? If not, why.?
-- We have two HOST & DB Details like this and would like to implement StandBy
Database:
Site-1:
Host OS: Solaris-10 3/05 SPARC
Host DB: Oracle10g R-2 10.2.0.2.0
Host DB1: IGFL
Site-2:
Host OS: Solaris-10 3/05 SPARC
Host DB: Oracle10g R-2 10.2.0.2.0
Host DB2: IGFL
Thanks & Regards,
Rishikesh

My 2 Cents:-
SID can be same.

Info on licensing issues of standby databases/Oracle Data Guard

Hi All,
Could anyone possibly give me some information on licensing issues of standby databases/Oracle Data Guard? Links to some electronic articles or journals might be useful. I am unable to find the appropriate info and need this quite urgently for my dissertation asap as my deadline is this approaching.
Thanks in advance

Paul Drake posted a reply to a similar question on the Oracle-L mailing list that pointed out that the License Agreement
http://oraclestore.oracle.com/OA_HTML/ibeCCtpSctDspRte.jsp?media=os_local_license_agreement&section=11365&minisite=10021&respid=22372&grp=STORE&language=US
states, in part,
"Failover: Your license for the following programs, Oracle Database (Enterprise Edition, Standard Edition or Standard Edition One) and Oracle Internet Application Server (Enterprise Edition, Standard Edition, Standard Edition One or Java Edition) includes the right to run the licensed program(s) on an unlicensed spare computer in a failover environment for up to a total of ten separate days in any given calendar year. Any use beyond the right granted in the previous sentence must be licensed separately and the same license metric must be used when licensing the program(s)."
which seems to open a bit of wiggle room depending on how the term "run" is defined. This is probably also an area where your Oracle sales rep may have a little more flexibility to negotiate

Creating standby database using data guard.

Current Env:
Oracle 11.2.0.1
ASM
Size 1.7T and growing.
I'm rebuilding a standby database and need to use rman because of a few factors. In the past, I did a file copy create a standby control file config init.ora and it always worked.
We have a database and had the stanby build; but someone issued a flashback and corrupted the standby database.
Because of the size 1.7T and growing and we are now using ASM.
My research is only showing building standby through rman using dupicate database command.
I would like to copy the cold backup to a external drive and ship it to the standby site where I'll do the restore. This is because of time and bandwith required to rebuild the standby will interfere with operaitions for the period the files are being copied.
So what would be the high level steps.
1) get the cold backup
2) create the standby control file
3) ship the data via corrier
4) restore the database
5) and this is where i'm not sure. recover the standby control file - but during the restore of the database the "normal" control file will open and perhaps do a checkpoint. therefore the standby controlfile will be usless.
6) recover the standby database.
Has anyone accomplished this?
As much specifics will be helpful. This system is operational and needs to be done right the first time.
thanks,
-Rob

Thank you.
1) I'm going to off load the cold backup to an external drive and have a courier take it to the DR site.
Why, we are replicating the SAN over to the DR site. When SAN replication backs up Oracle becomes non-responsive. Therefore; sending the data over the pipe is not an option for the standby rebuild. Yea' that's the easy way to do it. But this system is operational and critical to operations; so we will not risk saturating the pipe for any period of time. The pipe got saturated one time and it was not pretty.
2) I'm running the test in my lab to make sure I can create the standby database using the cold backup and rman.
3) In the past it was easy; I got a cold backup of the data files using the same ksh scripts that have been working for 20 years. Copy the files over to the standby site, and put it into managed recovery. This technique has been working fine sense Oracle 8i days. ASM through a huge monkey wrench in the ksh script backup and now I'm forced to use rman. Hey, I'm told it's an okay product but when it comes to backups I never get fancy; that just makes things more complicated. Okay I wont complain about asm anymore, i guess there is an advantage in there somewhere.

Difference between physical standby database and Data Guard

Hi guys,
Today I attended one interview. They asked me a difference between the Oracle Physical Standby database and Oracle Dataguard?
Upto my knowledge Oracle Physical Standby Database is one type of Standby Database can be configured using Oracle Databaguard Feature.
Can you people calrify me on this.
Regards,
Vijayaraghavan K

hello,
yes you are right upto some extent...here is para form oracle doc
Oracle Data Guard is the most effective and comprehensive
data availability, data protection, and disaster recovery solution
for enterprise databases. It provides the management, monitoring,
and automation software infrastructure to create and maintain one
or more synchronized standby databases to protect data from failures,
disasters, errors, and corruptions.
Data Guard standby databases can be located at remote disaster
recovery sites thousands of miles away from the production data center,
or they may be located in the same city, same campus,
or even in the same building. If the production database
becomes unavailable because of a planned or an unplanned outage,
Data Guard can switch any standby database to the production role,
thus minimizing downtime and preventing any data loss.oracle data guard is maximum availiblity solution which maintain physical standby databases and in case of failure of production can switch production role to and standby database.

Switchover of a manual standby database (no data guard)

Hi all,
I have a standby database .
I am using Oracle Standard Edition 10.2.0.4 / 10.2.0.5 so I have build a manual standby .
I am able to do a failover in the case something goes wrong; I was thinking if it is possible to do a manual switchover . and failback.
Do you thick that mounting the primary database and applying ALL archivelogs and online redolog to the standby database is enough ?
Do you think this is a supported operation?
How can I check the current scn of a mounted database? (v$database.current_scn shows 0 until the database is opened )
thnk you for every answer
Andrea

helter_skelter wrote:
hi,
You can see current_scn of standby database in v$database.current_scn. It is null only on primary database if it's in mount state.that's the problem: I am unable to mount both database and to check they have the same current_scn
not all changes are written to ARL so you can't recover standby database to exact the same SCN as primaryI thinks this is because the last changes are only recorder in online redolog, so I was thinking that a possible way to simulate a clean switchover could be as follow:
1 - shutdown immediate the primary database on server prod1
2 - shutdown abort the (manual) standby database on server dr2
3 - copy archivelog, controlfiles, tempfiles, onlinelogs from primary to the standby database
3 - copy controlfiles from standby database to primary database
4 - open the database on server dr2. It should open "read write" cleanly (mount + recover from archivelog + recover from onlinelog + open noresetlogs )
5 - mount the database on server prod1. It should mount as a physical standby database.
What do you think about it?
thanks,
andrea

The Critical Problems for Creating Standby Database

The Critical Problems for Creating Standby Database:(I want to create a physical standby database on the same system of the primary database)
1. Should I copy all the backup datafiles, standby controlfile and password file to a same directory before the first time to mount the standby database?
2. Before mounting the standby database, Should I change the datafile's name to a new one in the standby controlfile? How to change them?
3. When issuing the command to mount the standby database, should I specify the controlfile's name.(using which controlfile to mount)
These problems are not clearly secified in Oracle documentations.

Can you point us to the Windows specific documentation you refer to?
The parameter DB_FILE_NAME_CONVERT should take care of the new mapping for your datafiles (and LOG_FILE_NAME_CONVERT for logs), so you should be able to put them where you want and use the parameter to point Oracle to the correct location. You should not need to change the name in the controlfile.
Place your standby controlfiles where you have the control files defined in your parameter file and Oracle should recofgnise that it is a standby db. You should not need to specify which controlfiles to use (if this is even possible), your CONTROL_FILES init parameter points to them.
Not sure about the password file....my instances are on separate boxes and the password file has the same name on both primary and standby.

Use of Flashback Database in Data guard environments

11.2.0.3/RHEL 5.8
I've come across several docs which talk about configuring FLASHBACK DATABASE in dataguard environments. We have several
Physical standby DBs (Single Instance & RAC) running in our shop.I would like to know two or three major(common) use of FLASHBACK DATABASE in data guard environments.
I understood one use mentioned in the below URL ie. recovering from a logical mistake
http://uhesse.com/2010/08/06/using-flashback-in-a-data-guard-environment/
I would like to know what are the other major/common use of Flashback Database feauture in DataGuard environment

A couple of other uses:
1) You can use flashback to test your DR. So you can activate your standby. Test application/network connectivity and functionality on your DR site and when done revert this database back to a physical standby. You do however have to ensure that this is allowed in your environment. In some places I have worked this would be a big no no as there were zero data loss requirements. However some companies will allow this as long as the standby is back in place within a certain time period.
2) In the case that you have to do a failover for whatever reason, but then what was the primary site becomes available, you can flashback what was your primary to make it the standby rather than re-instatiating the database from scratch.
Eg. You have a power outage at your primary site so you perform a failover and your standby becomes the primary. Once what was your primary site is back online, you can convert your previous primary into a standby by doing a full back/restore (or whatever method you choose) to recreate your standby again. However you also have the option of using flashback on this database and then convert it into a standby as this would potentially be quicker than re-instantiating the standby.

OEM for physical standby database

Hello All,
I am using Oracle 11.2.0.3. My enterprise manager is db console 11.2
I have Oracle Enterprise manager dbcnsole for my RAC primary database and I have created through sqlplus command line a physical standby database.
My questions
Can I use the RAC primary dbconsole to monitor my physical standby database? if yes what the steps?
Is it mandatory to use grid control in that case? if yes, what steps are needed to implement grid control ?
Regards,

Hi,
It is not possible to monitor/administer a Logical or Physical Standby database, i.e Data Guard, using Enterprise Manager Database Control. This is primarily due to the fact that Database Control is designed to monitor 1 database and a Data Guard environment, by definition, includes more than 1 database.
If you attempt to run emca against a standby Database, you will get an error like (i.e. ORA-01219: database not open).
Database Control, can, of course, be used to monitor the current Primary database (with no ability to administer or monitor Data Guard related functionality). In such a case, when failover occurs Database Control must be reconfigured to run on the new Primary database using the commands detailed in Note 278100.1 How To Drop, Create And Recreate DB Control In A 10g Database, section C. Recreate/ReConfig DB Control, Option 2. Recreate the DB Control Configuration Files and Repository.
Enterprise Manager Grid Control or Cloud Control provides the functionality for viewing, monitoring, and administering primary and standby databases in a Data Guard configuration.
Reference: Is it Possible to Configure Database Control for a Logical or Physical Standby Database? (Doc ID 315116.1)
Using EM cloud control 12c is best available option to monitor your standby databases

Rman clone ? duplicate database ? data guard ? standby database?

hey there !!
What is the difference between Rman clone , duplicate database , data Guard , standby db?
1 more thing , standby database and duplicate database are same??

RMAN Clone : you take backup of a database on one server ,then take it to other server ,again use RMAN to restore the database,A lot manual intervention is needed in this method
RMAN DUPLICATE: same as above just that manual intervention is less. With 11gR2 there active database duplication in which you can clone your test database directly from production database without taking and then transferring the backup to test server.
Standby Database :they are of two types Physical and logical.The setup is done using RMAN with any of the above methods.Standby is the in-sync (can have some delay) version of primary database either block by block which is physical standby configuration or SQL statment wise which is logical standby.
Data Guard:This is also a standby configuration.Here the failover and switchover are automated with the help of DGMGRL utility.In manual standby this same can be done via SQL*PLUS using sql commands

DB link for physical standby database

Hi All ,
I'm facing the below error on primary while trying to create a db link pointing to the 10g standby database which is in mount stage.
SQL> create database link synct connect to system identified by 123 using 'stdby';
Database link created.
SQL> select max(sequence#) from v$archived_log@synct where applied='YES';
select max(sequence#) from v$archived_log@synct where applied='YES'
ERROR at line 1:
ORA-02068: following severe error from SYNCT
ORA-01033: ORACLE initialization or shutdown in progress
Database version is 10.2 standard edition
My requirement is i need to get max(sequence#) of standby database from primary database using db link.
what i was trying to do is
on primary get max(sequence#) & get max(sequence#) of standby using db link and compare both if the gap differene is more than 10 send a mail.
Any suggestions will be really helpful

Post Standby/DataGuard/ADG all questions further in Oracle Discussion Forums » High Availability » Data Guard
If you try to connect any users other than SYS in standby the error is very much expected. Of course you can connect with other users if you open database in OPEN READ ONLY mode, from 11gRx you can connect with other users even MRP is running if you are using ADG(active Data Guard licensed) .
I like to know, what you want to achieve by creating DB Link on physical standby database? Which is not allowed.
Database version is 10.2 standard edition
My requirement is i need to get max(sequence#) of standby database from primary database using db link.
what i was trying to do is
on primary get max(sequence#) & get max(sequence#) of standby using db link and compare both if the gap differene is more than 10 send a mail.
Any suggestions will be really helpfulNote:- Standard edition, Data Guard not enabled.
To use this you should use Oracle Net Service, you no need of DB Links.
Ex:- sqlplus sys/****@standby as sysdba
Here standby refers to Oracle net service, Where you will have entries in $ORACLE_HOME/network/admin/tnsnames.ora file.

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

Cannot Clear Critical Alert for Physical Standby Databases

10.2.0.4.0 Grid Control monitoring 10.2.0.4.0 databases and standby databases with 10.2.0.4.0 agents.
The standby databases are running on Xen guests. The O/S is Red Hat 4 Advanced Server.
I had a failure of Xen guest on Saturday that caused me to have to rebuild the standby servers. EM Grid Control successfully verifies the configurations and the status is normal for both physical standby databases. (A rebuilt logical standby database shows no alerts.)
Grid Control database targets page shows a single critical alert for each physical standby database. The alert is for "number of missing media files is 4". The metric graph shows the count as 0 since before the rebuilds. I cannot clear the alerts from the Critical Alerts page. Grid Control reports "The selected alert(s) cannot be manually cleared. They will clear automatically once the metric is no longer in a critical or warning state.".
Any suggestions?
Thanks,
Ray Westphal

Thanks for the reply Anthony.
The result of the query on both standby databases is '0'. The metric graph also shows the value at '0' since before rebuilds.
And the OMS db and agents have been reset several times since I posted this.
