Hi Pete,
Stop using my favourite answer :)
I'm not suggesting this is particularly scientific but here's a quick
test on dropping a moderate number of extents (9.2 on XP):
SQL create tablespace biggish

3 uniform size 16K;

hi, see inline comments below ...
There are some other effects I can think of.
Up to you if these are important / significant to your users.
If you make them bigger and you have a standby database then the standby
might end up being further behind production (unless you have a script to

Its not really a particular redo log that is the
issue. You've used up redo's (say) 1, 2, 3 and you
want to cycle around to 1 but the checkpoint that
would free up redo 1 is not yet finished.
Thus its not a single redo log that is the problem -
the IO rate of the checkpoint is not sufficient
Ok, I'll go for something controversial and lets see
if it can be shot down...
On the assumption that every system's maximum physical
I/O is a common divisor or multiple of the Oracle
setting for SSTIOMAX (which is 1m in most relevant
versions), then every extent for every segment should
be 1m
So do you think the following distribution will contribute to a better
performance:
data datafiles - device a
index datafiles - device b
redolog1 - device c
redolog2 - device d
redolog3 - device c

anything) or use old control file.
Incase, If you use old control file with combo of current relo logs then you
need to use
They make you work in the afternoon

Hello,
Oracle 8.1.7.4
HPUX 11.11
App is Famis Maintenance Management System
I have 3 instances TEST, TRAIN, PROD and I am trying to refresh the whole
famis schema on TRAIN with the famis schema on TEST.
Every time I try to do the import, I get compilation errors
Scott:
My first thought is to ask if there are any external references (other
schemas, SYS packages, etc.) in the triggers that may not exist in TRAIN
that do exist in TEST
