I'm currently using Oracle database 11g on RHEL5. My database generates a lot of archived logs per day even there is a small amount of changes to the database (about 500 transactions a day). I also check the size of my datafile (users tablespace); its size increases about 20MB a day but archived log generates between 5GB to 10GB a day.
Can anyone tells me what causes this issue? Is there any solutions to check why it generates more archived? How can I reduce it?
