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

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.

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.

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

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,

License for Oracle Data Guard

Hi
For a data guard solution, is the license including in the Oracle Data Guard package or we must buy additional license for the standby database ?
Thanks.

Hi
I will do that.
But i just wanted to know if a standby database means new license.
I mean, when the primary database works, the standby database do nothing except get the archive redologs.
And when the standby database is on, then the primary is down.
So i didn't see why we'll need futher licences.

Oracle Replication - Encrypted Data and Oracle Data Guard

We are working on a high availability architecture for one of our new projects. The preliminary architecture has Oracle 10g Release 2(10.2.0.2) production database (primary database) running on Solaris10 server for OLTP operations. And a production replicated database (standby database) is running on another node running on Solaris10 server for reporting, ETL data extractions etc. The plan is to implement Oracle data guard (DG) to replicate data between primary database and standby database (logical standby database). As a side note, there is going to be one to two minute time log for data synchronization between primary and standby databases.
We need to encrypt sensitive data (like SSN, Credit Card No. etc) in the primary production database. Initially we thought this can be achieved by using Oracle Transparent Data Encryption (TDE), this is a new encryption method Oracle came up with their 10g version. But the issue here is Oracle TDE doesnt support setting up the logical standby database (using Oracle data Guard) for reporting on the second node. I have confirmed with Oracle on this, so we are kind of stuck in the middle on this new requirement. So our next option is to look out for any third party vendors who can resolve this puzzle, and looking for your help for any suggestions.
· Do you know any vendor who can support both data encryption and data replication for Oracle databases?
· Do you know any vendor who can support just data encryption for Oracle databases?
(I am thinking if we can find a vendor, we would like to ask them if they have any technical issues working with Oracle data guard for data replication and use some kind of technique to decrypt the data on the standby/reporting database.)

You can always use the DBMS_CRYPTO or DBMS_OBFUSCATION_TOOLKIT to encrypt the data rather than using TDE. You may have to do some work on the key management side, though, but it shouldn't be too painful.

Veritas Hardware Cluster and Oracle Data Guard

Hi,
Actually we use Veritas Cluster Server for our Database Configuration. So we have a hardware standby cluster. In case of a failure the VCS does a failover, as you know ;-)
But now we are planning to use DataGuard for having a logical standby database for reporting cases. I just read something about a VERITAS CLUSTER SERVER AGENT for DataGuard.
What do I have to do (is there a possibility without using the Veritas Agent) for having a standby failover solution with Veritas and also a DataGuard Configuration.
What is going to happen if the Cluster does a failover? Will the Data Guard configuration be alive or is it going to break?
Please give me some advice. Maybe you have some links for articles that handle this topic.
Thank you very much in advance,
Henrik Ruenger

In terms of feasibility, yes, you can definitely have a database running on a Veritas Cluster Server and (at the same time) a Data Guard physical standby database.
If you are mentioning "VERITAS CLUSTER SERVER AGENT for DataGuard" by Symantec, I don't know the product in details.
What I can say is that you are definitely able to monitor and administer an Oracle Data Guard configuration by using just products that come with the Oracle licence.
In case of a failover, as long as your Oracle Net setup is resilient to the failover, Data Guard is as well. So, the short answer is: no it is not going to break.
I have setup this architecture several times with no problem.
Of course this is just high level.
Please let me know if you need more high level info.
Thanks and regards,

Oracle EBS R12 - DR setup using Oracle Data Guard

Hi,
Our customer has implemented Oracle EBS R12 (12.0.6) on a Two Node RAC on HP-UX env. The application Tier also has Two Nodes(Admin Tier and Web Tier).
Oracle Clusterware - OCR and Vote Disk are on Raw Devices and the EBS database is on ASM.
Customer wants to implement a DR solution with Oracle Data Guard with only 2 servers - 1 for the Database Tier and 1 for the Application Tier on the DR Site.
I would like to know if this could be done by following note: 452056.1? I would also like to know if there are other useful docs.
Thanks.
Thiru

Hi,
Customer escalated this issue to Oracle and they came up with this reply:
They can implement Disaster recovery solution from RAC to NON RAC using Solution A which use RMAN utilities for backup and recovery.
While now AMP Application Management Pack gives the capablitiy to build non RAC from RAC Envioment, In future AMP will be capable also to support cloning of DB with Data Guard.
Details
Solution A - Using RMAN:
For Release 12 customers, you can clone from a RAC to RAC (like to like) or RAC to non-RAC. This is using RMAN scripts to take a copy of the db when it’s in archive mode. if you’re leveraging any disaster recovery tools like data guard, the above solution should work fine…perhaps some fine tuning to the procedures
Solution B - Using AMP in the future release
For Release 11i , Release 12.x customers, AMP would be offering a new cloning solution that wouldn’t have dependency on Rapid Clone. This solution leverages the strengths of EM Grid Control in provisioning or cloning targets such as databases. This would be an advance solution that would support:
o A full-fledged scale down cloning
o Cloning of EBS deployed on Shared File System
o Hot and Cold mode cloning
o Quantifiable reduction in clone time for the entire EBS system
This solution would be leveraging EM grid Control’s DB provisioning pack’s clone utilities, that are quite advanced and support cloning of DB with Data Guard.
The recommendation is to start trialing AMP version 3.0, making the purchase and implementing within the Enterprise. As we release the new version of AMP (release 3.0.1), Customer would be in a better position to quickly implement the latest features
Can anyone let me know if the solution A suggested will work.
Rgds,
Thiru

Oracle Data Guard 9i

This is a quote from an Oracle publication on Oracle Data Guard 9i.
"Oracle Data Guard's new SQL Apply feature creates a "logical standby" that enables continuous access to a working copy of your primary database. With SQL Apply, the standby database is continuously available for reporting and other operations, while always at-the-ready for unplanned failovers. Data Guard provides log shipping, remote mirroring, zero-data-loss disaster protection, and a single point of control and automation. "
My question is: Is the standby database open in read-write or read-only mode?
If, its only read, is there ANY other way read-write version of a database could be created at a remote site besides:
a) Complete copying - duplicate database at remote site open in read-write.
b) Distributed database - replication - remote users access their own version and the two keep themselves in sync.
c) Parallel server - one database - two instances.

Data Guard is available for Linux (within Oracle9i).
It's a tool to make it much more easier to create a standby
database, but I don't think it's required!
Regards,
Thomas.
Is Oracle 9i data guard for Linux available??
Well, my real question is, I need to setup 9i standby database
on Linux. Do I need data guard installed in order to setup
standby database??

Difference between oracle Data Guard and Replication

Hello Friends,
I would like to know the main difference between oracle replication and data guard. Theoretically both are same then where is the difference. Can replication or dataguard be configured in a single PC.
Thanks

Dataguard :
Oracle Data Guard is primarily for high availability, data protection, and disaster recovery. An Oracle Data Guard Standby instance provides transactionally consistent copies of the production database, in the event of an unplanned outage or instance maintenance the Data Guard Primary Role Standby Role can be switched so the Standby instance can provide Production services.
Replication :
Oracle Advanced Replication and Oracle Streams are Oracle's solution for replicating data and internal structures to remote databases. Advanced Replication is primarily trigger based where Streams is a rule/handler based replication process and considerably more efficient and less error prone than Advanced Replication

Will Oracle Data Guard be replaced by Oracle Stream soon?

Will Oracle Data Guard be replaced by Oracle Stream soon?
In my opinion Oracle Stream can replace Oracle Data Guard completely.
Message was edited by:
frank.qian

While some of the technologies that underpin Streams are being increasingly incorporated into DataGuard, it's quite unlikely that DataGuard will go away.
Streams is the successor to Advanced Replication, which is designed to allow a source database to propagate data to a distinct database in a different environment without necessarily having to have the two databases tightly coupled. You can have different databases in different regions managed by different DBA groups who don't necessarily care whether any of the other systems are up using Streams (or Advanced Replication before it). Failing over between these systems, while possible, requires a fair amount of custom scripting, but is certainly possible.
DataGuard, on the other hand, is designed to allow you to have multiple copies of the same database that are tightly coupled for high availability. Similar in concept, but there are very different trade-offs in the design.
That said, Streams and Logical Standby both use very similar technologies to mine the redo information for change records. As DataGuard uses Logical Standby more and more, potentially as a replacement for physical standby, they'll use more and more of the same underlying technologies. They'll still be very different products.

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.

Oracle Data Guard

Hi,
do you know if is possible to configure Oracle Data Guard between Oracle 10g as source system and Oracle 9i as target system ?
Thank's in advanced

simple answer:
NO.
