SMON question

Hi DBAs,

I have a query about SMON. In Oracle 7 Every five minutes SMON looks
through the free extent table (sys.fet$) to see if there are any
adjacent free extents that can be coalesced into a single extent,
and on every 25th cycle SMON looks at the segment table (sys.seg$)
to see if there are any temporary segments that need to be eliminated.

My questions are :
1/ DO SMON still looks through the free extent table every 5 minutes
or has it changed on 8i/9i?
2/ Do SMON looks at the segment table (sys.seg$) every 125 minutes
or has it changed on 8i/9i?

TIA
