If you are planning to use sqlplus then you can use commands like:
alter database <table_name> add supplemental log data (all) columns;
alter database <table_name> add supplemental log data (primary key) columns;
For this demo,we will use Oracle GoldenGate command interface to add table level supplemental logging.The command from ggsci interface is "add trandata <table_name>".
