c) Set up the Checkpoint table

i) Create a GLOBALS file

— Global file need to create on target where replicat process running
— Checkpoint tables are only used by the Replicat, so no need to create on source because it’s one-way replication.

GGSCI (rac2.rajasekhar.com) 5>  EDIT PARAMS ./GLOBALS
-- Add below entries

ii) Activate the GLOBALS parameters

For the GLOBALS configuration to take effect, you must exit the session in which
the changes were made. Execute the following command to exit GGSCI.

GGSCI (rac2.rajasekhar.com) 7> EXIT


iii) Add a Replicat checkpoint table
