High log generation due to "Last Login Time Information" updates in 12c

edited Jun 20, 2017 5:01AM in Database Administration (MOSC) 3 commentsAnswered

We have a database with a very high login/logoff rate.  We have recently updated to 12c, which by way of a "New Feature" records the "Last Login Time".  Because of this we're now seeing the SYS.USER$ table account for a high number of block changes.

Is there a way to disable this behaviour?

This is what happens for each login....

update user$ set spare6=DECODE(to_char(:2, 'YYYY-MM-DD'), '0000-00-00', to_date(NULL), :2) where user#=:1

Howdy, Stranger!
