Hi
I am configuring a database for the first time, and i am not sure how to
determine the number of rollback-segments needed and how to dimension storage
(initial, next, minextents).
I have been told that the number of segments schould depend on the number
of transactions (v$transaction), e.g. if #trans > 32 -> #segments = #trans/4,
with an initial 20 extents, if #trans < 16 -> #segments = 4.
I have found some older databases on my system, configured with one RBS
of size 100 M (initial=10M, next=10M), wich seems quite large.
Can the RBS be configured too large (thinking of performance) ?
Any hints / pointers to manuals appreciated !
Thanks,
Thomas Petersen
