sample extract,pump and replicate(goldengate)




NAMING CONVENTION should be followed in any environment we are Implementing GoldenGate#
E starts with Extract 
P starts with Pump
R starts with Replicat 

Here we are taking
extract: EWORK
pump: PWORK
replicat:RWORK
###we are replicating schema pavan(including all tables)###

#Add checkpoint table on target side#

Oracle GoldenGate processes extract and replicat processes perform checkpoint operations, in the event of failure, the checkpoint file or database table ensures extract and replicat re-start from the point failure avoiding re-capture and re-apply of transactions. The GGSCI command below create the checkpoint table specifying the database schema and table name.

#After configuring extract, pump and replicat, try to add some sample data into tables present in schema pavan and commit on source side(test), then check for changes on the target side(clone)#

NOTE: The uncommited data will not appear on the target side
