ASSM vs. non-ASSM

edited Jan 25, 2012 12:17PM in Database Administration (MOSC) 2 comments
I am engaged in a discussion about moving from 10g --> 11g. The  tablespaces in this particular 10G are all created with the manual segment space management. I am reading the blogs and am aware of all the troubles that ASSM can cause, ranging from wasting space to problems with the free lists and even some spurious corruption issues.
However, Oracle made ASSM default in version 10g, and this project is about upgrading a large production DB. What are the opinions here? Does it make sense to go with manual SSM  or should I go with ASSM?

Howdy, Stranger!
