Home -> Community -> Mailing Lists -> Oracle-L -> SMON - Does it cause a degrade?
Hey Fellas,
I have an application DBA who insists that the pctincrease at the data tablespace should be set to 0 so that SMON does not coalesce the tablespace. He says coalesce will be performed by using a scheduled batch job written for that purpose. He states that having SMON to perform an coalesce of the tablespace could cause an performance degrade??? I have never heard of such a thing, but then I dont wanna argue with him. He's got wrinkles on his face, and grey hair ;-)
My argument would be, go back to the drawing board, get your tables sized properly, if you anticipate fragmentation. And SMON does not cause a performance degrade? It wakes up every 5 minutes, does hold ST enqueue locks if a tablespace needs coalescing, but it does not cause a performance degrade? Or does it???
Now, can I have a definitive word on this? Any sites, white papers, to refer to that says so, or to the contrary. I need to convince the higher ups.
Raj
