Trying to shutdown a database which takes about 10 mins sometimes to shutdown. According to my research I found out that smon creates temporary segments which it tries to colensce (release) and that takes time. I believe Oracle was saying that by increasing the sort area size this might help. My question is how do i know on which tablespace has these temporary segments been created?
What about increasing hash area size?

any suggestions?
