There are many reasons, I feel.
Basically, I am implementing ORacle change data capture (CDC ) in my 6 node
RAC database. And CDC will be applied on only around 50 tables out of 2000
user tables.
What Oracle says in documentation that I have to enable Supplemental logging
on database level.
And when we enable supplemental logging level on database level, the archive
log generation will go upto around 3-4 times in the database.
So just for 50 tables, the logging is going to affect the whole database.
Hence if there is any table level logging is there, it would really be
great.
