Oracle E-Business Suite and Active data guard

Hi,
I'm looking to setup current E-business Suite R12.1.3 application without any down time. I've Primary Data Center and Secondary Data Center. I would like to setup seamless failover to another secondary data center in case of 1st data center failure.
Can be this achieved by using Active Data guard? If not what would be best solution? In case of active data guard can I failover site to secondary data center and apply patches on primary site?
I want to acheive 100% availability of application. Any suggestions are welcome!
Thanks

Difference between data guard and active data guard

As in subject. Can we paid for both products?

>
Is this only one difference between this Data Guards?
>
The one (active DG) is an additional feature of the other (DG)

BTW, is that mean that Data Guard in each version (9-11) is free on EE?

Yes - but you need to license the Standby Database. So it is not really "free" - but you better ask that our sales people :-)

How to Display Data from Oracle E Business Suite tables in ADF

Hi,
I am new to ADF.
I have a requirement to Create an ADF page for Search Results Screen.
However the result data is from one of the Oracle E Business Suite Tables.
ie I need to create a Screen where user will enter a Purchase Order Number and Click on Button.
The Screen should show details from PO_HEADERS_ALL (from Oracle ERP Database Table) based on the entered PO Number.
Is it possible to implement the same? Can some one guide me how to do it?
Thanks,
Kamath

Hi,
Is there a way where I can create a VO in ADF to which I can insert records dynamically from a source and the Source connects to E Business Suite tables and returns results ie BPEL etc.

Just replace the PLSQL example with your data source
Can ADF invoke SOA which inturn connects to Oracle E Business Suite and fetches the data from Oracle tables and pass it back to ADF? Is it possible
Yes. Just use a WS proxy client to access the SOA entry point (WSDL) and follow the link above

Active data guard - patching

Hi Gurus,
I have primary db amsprd and active data guard amsprd_stby.
we are planning to apply application patches in amsprd. earlier we used to rely on rman backup for restore in case of any failures.
I would like to make use of standby as primary and keep the business up immediately after application patch failures.(to reduce the downtime - application failures are not having any rollback steps :-( - vendor product).
to achieve this,
before application patch application
do i have to just stop the log shipping?
or do i have to stop just log file apply?
what are the steps involved in case of primary applicaiton patching failures.
Thank you.

So the Application Patch may turn out as a "Logical Mistake" from the Database perspective.
One option would be to stop the Apply on the Standby Database. If your Application Patch was no good, you could do an "Immediate Failover" which will open the Standby immediately without applying the received redo first like an ordinary Failover would. You would have to create a new Standby Database on your Ex Primary site then.
Another option would be to turn on Flashback Logging on both sites. If your Application Patch was ok - nothing to do. If not, flashback both sites to before the App Patch. Look here for an example:
http://uhesse.wordpress.com/oracle-database-ha-architecture/2010/08/06/using-flashback-in-a-data-guard-environment/
Second option has the benefit that you do not delay an emergency failover, should your Primary incidentally get destroyed during the App Patch. Also, if you need to rewind the Logical Mistake, you do not need to recreate the Standby completely. If you are on 11gR2, you can even turn on/off Flashback Logging without having to restart:

Want to start a Career in Oracle E - Business Suite.

Dear All,
This is Hitesh Parsawala. I am working as a SAP B1 Project Head. Till date I have completed 4 Implementation Projects. Basically i am a functional Consultant.
But as SAP B1 Product has various contraints and Limitations hence i have found interest in Oracle E - Business Suite and make my career in Oracle EBS.
So can any body give brief about the modules covered in Oracle E-Business Suite. And just brief me about Oracle EBS.
Also can anybody suggest which are modules covered in Functional side in Oracle EBS (Especially in the MM and SD ) side.
Can anybody tell me is it possible for me to shift myself from SAP B1 to Oracle E-Business Suite. Also is it possible for me to learn the Technical Module in Oracle EBS. And which are Technical Modules covered in Oracle EBS.
Waiting for the reply.
Regards
Hitesh Parsawala

Hello dear,
Thanx for the reply. But i had visited the site, but i wanted the suggestions regarding my shifting to Oracle EBS and the Market of Oracle EBS.
Also is it possible for a Functional Consultant to move from functional side to technical side.
Plz reply.

Basic Questions about Oracle E-Business Suite

I am just now starting to learn about Oracle E-Business Suite.
I am an Oracle DBA, and I want to become an "Oracle Apps DBA".
The following questions pertain to the DATABASE side of E-Business:
*(1)* Is "Oracle E-Business Suite", and "Oracle Applications 11i" the
same product?
*(2)* Is Release 12, the current version of E-Business Suite?
*(3)* What is the Release of E-Business Suite that most Businesses are
currently using?
*(4)* I want to use 1GB of RAM, for the Laptop, that I want to install
E-Business Suite on, and it will be running under Oracle
Enterprise Linux -- Will this type of setup be OK for building a
personal training and learning environment (especially RAM size)?
*(5)* How much disk space do I need, just to do a basic install (no
demo databases)?

Hi,
*(1)* Is "Oracle E-Business Suite", and "Oracle Applications 11i" the
same product?Yes, it even includes R12.
*(2)* Is Release 12, the current version of E-Business Suite?Yes, the most recent versions of R12 are (12.1.1 and 12.1.2).
*(3)* What is the Release of E-Business Suite that most Businesses are
currently using?Depends, some customer still on 11i while other customer managed to upgrade to R12 (or did a fresh installation/implementation of R12).
*(4)* I want to use 1GB of RAM, for the Laptop, that I want to install
E-Business Suite on, and it will be running under Oracle
Enterprise Linux -- Will this type of setup be OK for building a
personal training and learning environment (especially RAM size)?1 GB RAM is not enough, I would suggest you have 4 GB RAM (or more if possible).
*(5)* How much disk space do I need, just to do a basic install (no
demo databases)?This is documented in the installation manual, please refer to it to get the hardware requirements.

What are the pros and cons using Active Data Guard vs Data Guard?

My understanding is that Active Data Guard is an additional database option for Oracle 11gR2 Enterprise Edition. I need to know the pros and cons using Active Data Guard vs Data Guard in order to decide whether to get pay extra for the Active Data Guard.
Thanks for any help.

Before jumping in to Active Data Guard, one needs to evaluate :
a. Is there really a need to run queries on the Standby ? The Standby could / should be at a remote site so queries are "across the network". Depending on the nature of the queries and the volume of output, the "performance" of the queries may not seem to be the same.
b. If the database is not in Maximum Protection mode, the data "seen" at the standby may not be in "real-time" synch
c. Not all applications are truely read-only when querying. Some applications use "jobs" that write to tables when querying. Such would not work with Active DataGuard. (example : EBusiness Suite). There are very complicated ways of handling this -- and one needs to consider if the complications can be introduced and supported.
Over the network accessing standby read only is really not an good idea, I think no one will compare performance with primary and standby,
But some of them they want to validate data which are very critical, as it is matching with primary or not, Its an added advantage with ACTIVE DATAGUARD
Prior to that until unless stop MRP, open database and then we need to validate, So there is an interruption of recovery, I can say its also an advantage where there is no interruption of recovery.

Oracle E-Business Suite 11.5.10.2 DATA GUARG

Hi,
I'm planning to implement Data Guarg in Oracle E-Business Suite 11.5.10.2 .
Production Server:
DB01 =DB SERVER (10.2.0.3)
APP01 =APPLICATION SERVER (11.5.10.2)
DataGuard Server:
DB02 =DB SERVER (10.2.0.3)
APP02 =APPLICATION SERVER (11.5.10.2)
Can I do automatic applciation failover? My answer is yes.
Which failover would be suggested method if users are <100?
What will happen when I apply patch on APP01? Do I need to refresh APP02 thru scp or tar or any backup utility?
Since DB02 is syncing thru DB01 on daily basis.
Does DG required additional licenses?
Thanks,
-Dinesh

As Srini and Hussein mentioned that there could be some data losses. No dear, I did not say there will be some data loss (Srini who mentioned this in his last reply as shown above/below).

DB link problem between active Data Guard and report application database

My database version in 11.2.0.2.0 and OS is Oracle Solaris 10 9/10.
I am facing a problem in my Active data guard Database for reporting purpose. Active Data guard information is as below.
SQL> select name, database_role, open_mode from v$database;
NAME DATABASE_ROLE OPEN_MODE
ORCL PHYSICAL STANDBY READ ONLY WITH APPLY
Problem detail is below
I have created a db link (Name: DATADB_LINK) between active data guard and report application database for reporting purpose.
SQL> create database link DATADB_LINK connect to HR identified by hr using 'DRFUNPD';
Database link created.
But when I run a query using db link from my report application database I got this below error.
ORA-01555: snapshot too old: rollback segment number 10 with name "_SYSSMU10_4261549777$" too small
ORA-02063: preceding line from DATADB_LINK
Then I check Active Data Guard database alart log file and get below error

But the interesting point if I run the report query directly in Active Data Guard database, I never got error.
So is it a problem of DB link between active Data Guard and other database?

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.

Active Data Guard in different database versions (11.2.0.3 and 11.2.0.4)

In case of Active Data Guard can i run different database versions (11.2.0.3 and 11.2.0.4) at Primary and DR for production environment ? And will having RAC in environment make any difference?

Hi,
>>In case of Active Data Guard can i run different database versions (11.2.0.3 and 11.2.0.4) at Primary and DR for production environment ?
As per normal Data Guard requirement, Oracle 11.2 does support flexibility where Primary and Standby may have different hard wares such as CPU architecture and OS etc. but the Oracle RDBMS software version must be the same. Having said so does not mean it will not support it. Beginning with 11.1.07, a physical standby database can be used to execute a rolling database upgrade to a new Oracle Patch Set or database release by using the transient logical rolling database upgrade process. It means you can have with different database version but for how long, you need to check above documents.. For complete information you should read this note:
Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration (Doc ID 413484.1) &
http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-transientlogicalrollingu-1-131927.pdf
2) >> And will having RAC in environment make any difference?
NO. You can find answer at - https://docs.oracle.com/cd/E11882_01/server.112/e41134/standby.htm#SBYDB4716
**The primary database can be a single instance database or an Oracle Real Application Clusters (Oracle RAC) database. The standby databases can be single instance databases or Oracle RAC databases.
