Hi All,

I have a scenario here, which my friend is facing
Recently one of their database is migrated from 10G to 11G.
Before migration, per day 10Gb archives logs were generating and after the migration the archive log generation is 100Gb per day. Business transaction is normal and there is no increase.

Does anybody have some idea what is behind this behaviour of the database ?

Oracle database version:-
Plat form:- Windows.
