When does a user or job need its own TEMP tablespace?
The customer's DBA is resistant to creating more TEMP tablespaces (much less TEMP tablespace groups), and it appears that contention for the lone TEMP tablespace (2 TB and climbing) might be part of the problem. I want a couple of users to have their own TEMP tablespace.
So how do I determine when a given job or user needs their own TEMP tablespace? In other words, measuring contention for the TEMP tablespace over a given time period, and showing that the wait events are "too high"?
