Check Table-Level Supplemental Logging

SQL> select t.owner,

  2         t.tbl_cnt,

  3         s.sup_log_grp_cnt,

  4         t.tbl_cnt – s.sup_log_grp_cnt "Diff"

  5    from (select owner, count(*) tbl_cnt from dba_tables group by owner) t,

  6         (select owner, count(*) sup_log_grp_cnt

  7            from dba_log_groups

  8           group by owner) s

  9   where t.owner = s.owner(+)

 10     and t.owner in ('HR', 'OE', 'PM');

OWNER    TBL_CNT SUP_LOG_GRP_CNT       Diff

HR             7

PM             2

OE            12

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>".
