Hi,
do you think that these redo log switches are happening too often ? Oracle seems to recommend "no more than once per hour"
How can you judge that ?
Thanks,
Andy

no, there's no problem but just curious. Our other databases have a much less frequent redo switch frequency.

It depends on the work load on the database.
May be other databases are not facing that much of DML/DDL activities like this.
