Hi guys!
Anyone seen any issues with large locally mananged extents?
Recently I noticed one of my applications taking a long time to do
truncates.
And an index rebuild where I increased the locally managed extent
size from 16K took almost an hour for 58,000 extents when larger indexes
(and extents) only took 3-4 minutes.
I once had a purchased app using a 16K extent size for huge tables
took 2 hours and 7 minutes to do a truncate on just one table (dictionary
managed). I killed it the first time after 45 minutes cause I thought it
was hung up somewhere else.
Not sure why it was set to 16K in the first place. Good for testing
I guess.
Thanks
Larry
