Implementing a data guard on VMs

Hi all,
probably this is not the place where I have to post this question, but I need your help about interconnecting two VMs running on separated hosts. My problem is that I can't connect to my VMs (redhat 6.4 32 bit) from a remote host(ping is also impossible) but I can ping a remote host from the VM (and can ping the host on witch the VM runs).
thanks for help
best regards
Rachid

Hello;
I have this set up as 3 VM's:
A RMAN Server
A Primary Server
A Standby Server
What I do is add the hostname of every server to every /etc/hosts file. Then I can ping, Net80 works etc.

Looking for Active Data Guard in Oracle 11g Release 2 References

I want to reach out to customers who have implemented Active Data Guard in production (preferably 11.2), so that we can develop some
customer references that in turn will benefit other customers. The customers who get selected for such references may further be selected to publish their case study directly in oracle.com and/or invited as a customer co-speaker in the upcoming Oracle OpenWorld at San Francisco (Sep 19-23, 2010). Being a customer co-speaker at OOW means they get a free pass to the full conference (regular price for that is $1795-$2495).
Please send any follow-ups to [email protected]
Thank you.

Hi Larry,
This is Bhavik Desai Oracle -DBA@Amazon. I do have couple of Active Standby running on 11gR2 On RHEL 5 64-Bit platform.
Most of the databases are reporting on (DSS Having 2-4 TB in size) having FSFO configured.
It would be a pleasure if i can provide any benchmarking to you on this.

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.

Active Data Guard License is technical or legal ?

Dear friends
I have seen in many documents , that the Active Data Guard needs additional license , but one of my friends said that he could implement Active Data Guard without any licenses ( he only downloaded the Enterprise edition of database 11g r2 ).
my question : is the active data guard license , a technical license or legal license ?

If you have a server that has an Oracle EE database on it, you need to license it. It doesn't matter if only a standby database is on the server - DataGuard is just a feature like other features. One server with a primary + one server with the standby = 2 servers you need to pay licenses for.
Everyone else, relax, answer the question, and stop waving your Big Swinging Audit Team language. The original poster demonstrates how widely misunderstood Oracle licensing is among DBAs - which given how often it's changed, is not a surprise ;-)

Oracle Data Guard, SAP instances not coming up after switchover

Dear Experts,
We have implemented Dataguard, Uisng Maximum performance with real time apply (redo log apply). Redo logs are apply from primary to standby perfectly. And the SAP Instances are up and running, when we create a user in primary its reflecting in standby server.
When i do the the switchover from primary <--> standby. There is no communication between R3 and database. I have refered the Note 400241, have not got the solution. I changed the password of the OPS$ user uisng brtools utility. Still getting the r3trans return code 0012.

Hi Nisar,
We would like to implement the data guard , the system landscapes are also similar to your site. Can u pls give me the documentation which explains step by step configuration. We are not able to activate oracle enterprise manager where the configuration is slightly simple. Is it possible to have the primary and standy database with same db_name?. Pls help to proceed further.

Recomendation: RAC + ASM + Data Guard

Hi all:
I need to implement a Data Guard in my 2 nodes RAC Database.
How I make the ASM instance in the remote host?? I'm not found any documentation...
Please, any sugestion.
Thanks a lot.

Use the same installation procedure as you used for RAC.
Check these example instructions for Linux.

Data Guard Implementation Importing one schema will it reflect in other?

Hi All,
I have succesfully implemented data guard (Primary) and Physical Standby
for 10g R2.
It works fine. I would like to know if on the primary if I remove one schema and import the data/objects using a dump file will it get reflected in the standby?
ie we have to refresh our primary database with actual production data by dropping one user (prod) and its objects. And I will run the import(dump file) in order to bring the data from production
Will this refresh the data in the standby ?
Thank u all
Rajesh Alex

The answer is Yes, that's the goal of the dataguard configuration, to replicate all changes from the primary to the standby database.
Any DML or DDL is recorded by the redolog mechanism, and the redo information is transported from the primary to the standby database where the information is applied, exactly the same way it was applied at the primary database. DDL commands (create, alter, drop) are considered transactions against data dictionary tables, so they are recorded just like any other DML transaction on the redolog mechanism and transfered just the same to the standby.
The time it will take to get replicated at the standby database will depend on the kind of Dataguard configuration you have, if you have a high avilability or a high performance configuration.

Data guard implementation

Hi ALL
i want to install a data guard on windows servers.
So i got two windows servers set up.Now i need to implement data guard.
Since both the servers are new and only oracle in installed,it will be easy to implement.So before proceeding i want to take all your suggestions.
Thank you one and all........................

Hi, i recommend you read the next documentation before start with the configuration,you can design your environment careful attention to detail and get more performance in your implementation.

Administrating Data Guard without complexity of Grid Control. Possible?

I wonder if someone can shed some wisdom about implementing and administrating Data Guard without the complexity of Grid Control. Don't get me wrong, I love the Data Guard feature provided by Grid Control, but installing Grid Control just for the sake of administrating Data Guard sounds a bit overkilling. Not to mention that I still have hard time getting Grid Control properly installed on a Windows Server 2003 box (keeps getting 503 Service Unavailable and the Servlet error).
I was told by a friend that Oracle 9 has something called EMCA (Control Assistant) that allows you to administrate Data Guide. Searching for any file containing the phrase "emca" under the Oracle directory ("c:\Oracle\product\10.2.0\db_1\BIN"), I found emca.bat and some related files. Does it mean the EMCA is actually existing in Oracle 10.2G (for Microsoft Windows Server)?
Any comment? Feeling clueless right now. :-I ....

I have set up Dataguard 9iR2 on Linux SLES8 and use Data Guard Broker to manage switchover and failover operations. It comes with the database and is command-line based.
The documentation walks you through the setup phases quite nicely.
http://www.oracle.com/pls/db92/db92.to_toc?pathname=server.920%2Fa96629%2Ftoc.htm&remark=docindex
I would suggest a read of some of the documentation on metalink surrounding dataguard and the broker before attempting to use either ;)

Protection type for Acrive Data Guard

Hi all,
I am looking at implementing a 11G R2 active data guard solution and need to do live reporting from the physical standby database.
I need confirmation of the protection mode I will need. (I think it's Maximum Protection).
Many thanks
VicC

Sorry, I just realized that I misunderstood your Question as "What Protection Modes can I have with FAST-START FAILOVER".
For Real-Time Query, you can be in any Protection Mode.
Kind 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.

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

Data Guard, Grid Control 11, GI 11gR2, and DB 10gR2

Hi,
I'm seeing a rather odd behavior, and I'm hoping someone else has already been through this and knows what I'm doing wrong.
I have an installation of Grid Control 11.1 (recently patched) which I am using to create Data Guard replication of some 10gR2 database instances. For some confusing reason, sometimes when I use the GC wizard to add the standby database, it creates the listener for the new database in the EM Agent's OH/network/admin/listener.ora. Other times, it creates it in the 10gR2 DB's OH/network/admin/listener.ora. When it does the former, creation of the standby DB seems to work fine, but when it does the latter, not so much.
If it matters, my primary DB is 10.2.0.4 on 10.2 grid infrastructure, and my standbys are 10.2.0.4 on GI 11.2.0.2.
I have applied the latest PSU to my agents, so they are all the same version, so I'm confused as to why this might be happening. Has anyone else seen this issue?
Thanks,
Bill

My recommendation would be to not use OEM Grid Control to create your standby.
Even when it is working properly ... it does not create what I would consider a good implementation. Just as I don't consider the vanilla installation of the Oracle database by the OUI (all control files and redo logs in the same directory with the datafiles) very good.
You'd be far better off hand crafting your standby using two listeners ... one for public and one for replication.

Data Guard Vs Golden Gate

Hi Experts,
I am looking for High Availability and Disaster Recovery architecture for my data layer i.e. Oracle Database 11g R2
We have two physical locations and the distance between two sites is around 20 miles.
Site 1:
We already implemented RAC setup with two node in site 1.
Site 2:
We are going to implement standalone database. (Not RAC)
My requirements:
1. Both databases at Site 1 & Site 2 should be replica of each other.
2. Both databases should be in sync always.
3. Site 1 is active and Site 2 is stand by.
4. Client applications on Site 1 & Site 2 should always talk to RAC database on Site1.
5.. If RAC at site 1 goes down completely, then ONLY client apps should connect to Site2 database without human intervention.
How can acheive my requirement ? I was doing some research & found two solutions. 1. Active Data Guard 2. Golden Gate.
Questions:
1. Do Data Guard and Golden Gate offers same features ?
2. Which products offers solutions to all my requirements or Do I need to use both ?
3. If Data Guard and Golden Gate are different from each other then What is the difference between them and what are the overlapping features among them ?
Thanks

1. Do Data Guard and Golden Gate offers same features ?No, there's simple compare here :
http://www.oracle.com/technetwork/database/features/availability/dataguardgoldengate-096557.html
2. Which products offers solutions to all my requirements or Do I need to use both ?Data Guard will work and you don't need anything else. I cannot speak to Golden Gate.
3. If Data Guard and Golden Gate are different from each other then
What is the difference between them and what are the overlapping features among them ?Again this document :
http://www.oracle.com/technetwork/database/features/availability/dataguardgoldengate-096557.html
1. Both databases at Site 1 & Site 2 should be replica of each other.
Data Guard can do this.
2. Both databases should be in sync always.
Data Guard can do this.
3. Site 1 is active and Site 2 is stand by.
Data Guard can do this.
4. Client applications on Site 1 & Site 2 should always talk to RAC database on Site1.
You can set your tnsnames to handle this and more. Using DBMS_SERVICE you can create an alias
to handle this.
Ex.
ernie =
(DESCRIPTION =
    (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP)(HOST = primary.host)(PORT = 1521))
       (ADDRESS = (PROTOCOL = TCP)(HOST = standby.host)(PORT = 1521))
       (CONNECT_DATA =
       (SERVICE_NAME = ernie)
)5. If RAC at site 1 goes down completely, then ONLY client apps should connect to Site2 database without human intervention.
You can set your tnsnames to handle this and more.
