Hi T N,
Integrated Capture is one of the New features of Oracle GoldenGate  11g. In Integrated Capture mode, the Extract process does not directly reads the Redo Logs. Instead, it directly interacts with the database log mining server.
The log mining server reads the database redo logfiles and captures the changes in the form of Logical Change Records. These records are then written to the Oracle GoldenGate trail files by the Extract Process.
Earlier in Classic Capture Mode, the Extract directly reads the Redo Logfiles, captures the changes and writes it to the GoldenGate Trail Files. But here it is totally different. The Oracle has binded the GoldenGate process with the Oracle Log Mining Server to capture the changes and hence it is has been named as Integrated Capture.
To Integrate the Extract with the Database Log miner server, we need to first Register the extract with the database.
REGISTER EXTRACT <EXTRACT_NAME> DATABASE
This registers the Extract with the database to make the Extract process integrate with the Oracle Database Log miner server. Once you Register your Primary Extract to the database, automatically dedicated Log Miner Server will be assigned to that Primary Extract Group. So that Log Miner Server will capture the changes from the Redo Logs and gives it to the Extract process which in turn is written to the GoldenGate Trail files.
Only Primary Extract can be registered with the Database. I mean if you are using a Datapump extract, you cannot register it to the Database.
