Oracle Technology Day on Data Integration -- 18th May 2011 Bangalore at Oberoi's

One of the conferences that I attended over last few months was Oracle Technology Day on Data Integration. This happened on may 18th 2011. Couple of presentations on Data Integration and GoldenGate. Interesting topic for me was on GoldenGate 11g Zero downtime upgrades and migration. This is one of beautiful features of GoldenGate through which you can achieve Zero downtime for upgrades or migration (This does not mean that no downtime required, downtime can be reduced to nearly zero but not zero). Unfortunately this feature cannot be used with CRM/ERP upgrades as E-Business Suite is not completely supported by GoldenGate. There are about 20 objects specific to E-biz suite which are still under development to be included with GoldenGate. As GoldenGate is an acquired product Oracle this development will take some time to get supported. Following are the list of presentations and details of the sessions I attended. Please go through this, share it with your colleagues/friends and let me know if this was useful.

Comments

I have a question about Flashback Data Archive tables in Goldengate replication. Are these tables usually excluded in an extract like "TABLEEXCLUDE .SYS_FBA_*"?
What is the approach for replicating and initial load of Flash Back Data Archive tables?
Here is my problem. I exported a user schema using Oracle DataPump, imported into destination database. GoldenGate abended saying some tables dont exist on dest. I checked tables and there were about 200 tables that were not exported because they are FBDA tables and DataPump just ignores them. So, I recreated them on source with scripts.
So, how is this done? Source and destination have their own FBDA and these tables should not be neither recreated with scripts on dest or replicated? Or they have to be replicated with contents?

Basics of RDBMS

Data
Small set of information becomes data, this set of information helps make decision. Data is always some useful information.


Database
Place where you store the data. Database represents some aspect of the real world called "miniworld". A database is designed, built and populated with data for a specific purpose. It has intended group of users and some preconceived applications in which these users are interested.

In other words, a database has some source from which data is derived, some degree of interaction with events in the real world and an audience that is actively interested in the contents of the database.

Database can also be defined as collection of one or more tables.

Ex: Mobile, human brain etc



DBMS (Database Management System)
Is a program that stores retrieves and modifies data in the database on request.
