USERID ogg, PASSWORD ogg

The EXTTRAIL / u01/app/ogg/dirdat/aa trace extraction file is placed in the / u01/app/ogg/dirdat directory with the file name prefixed with aa: example aa000000

TABLE scott.TCUSTMER; capture (capture) the name of the table to be monitored. Capture can monitor multiple tables or one table by value.

TABLE scott.TCUSTORD

Please note that "aa" is prefix for local trail file.

Execute the following commands in source system to add Primary Extract group.

GGSCI (gc2) 22 > ADD EXTRACT EORA_1, TRANLOG, BEGIN NOW

EXTRACT added.

ADD EXTRACT EORA_1: add an EXTRACT process, which means running all the time, and no one will grab the log in the redo as soon as it stops.

TRANLOG, BEGIN NOW: start synchronous logging now, or use asynchronous, so you need to configure it separately

Define GoldenGate local trail

GGSCI (gc2) 24 > ADD EXTTRAIL / u01 MEGABYTES MEGABYTES add trace EORA_1 for EORA_1 with a size of 5m

Indicates that the log series number read now is the location where the checkpoint occurred in sequence 9, which is related to the MTTR setting, and where the checkpoint occurred.

That is, the dirty data blocks before this checkpoint are written to the data file through DBWn, and the location where the checkpoint occurs is RBA. A new era begins again, and the previous checkpoint is preserved.
