Here is quick summary of day 1 session and tasks assigned to it:

A. Oracle Goldengate Architecture - How data flows in Goldengate?
All the processes in Goldengate work independently from each other however they depend on each other for reading the data. We call capture process as extract process as well. There are two types of extract processes.
1- Classic Extract process
2- Integrated Extract process

Classic extract is there since beginning . Capture process is external to database and it reads the data in sequential manner and capture only committed transaction. In integrated capture log minor build happens and logminer sends changes in the form of LCR to the Extract process. Performance of integrated capture is very high and much faster than classic capture. It creates less load on the database as well.

/response/oggcore.rsp
--Silent installation , You can use the response file
--You need to have Different GG install for Different versions of the Database

GGSCI is the command to invoke the GG
--Go to GG home
