Home -> Community -> Mailing Lists -> Oracle-L -> RE: coalesce tablespace
Agreed. I rather prefer temporary temp tablespace with tempfile and uniform
LMT which even does not require coalesing infact that is an invalid option
for that. But one must have 8i database to use it.

SMON very poorly does coalesce and a source of many problems. (ST Enqueue which is serial for atomic modification of the data dictionary).
I always set my PCTINCREASE 0, and manually coalesce or use LMT.

Yes, But in your case being pctincrease set as '1' you will most of the time
see 100% in your last column. Even if you don't coalesce manually, it will be done by smon internally with regular interval...

Does this also apply to a temporary tablespace?? I have a temp TS that has a percent extents coalesced of 1.
Thanks,
Dave

Following script may be used to check whether coalesing is required or not. If lasr column not 100% then coalesce that tbs....
select substr(tablespace_name,1,10)TS_NAME,total_extents
"Total_Extnts",extents_coalesced,round(percent_extents_coalesced,0)
from dba_free_space_coalesced

It would take contiguous free extents and make them larger extents, which would be more likely to reuse. Especially if there are many smaller ones, this moot if using LMT.
It is a very quick procedure and good to do occasional, you can check in dba_data_files_coalesced to see if the number is far from 100%, if it is less than 75% or so, just throw a coalesce on the tablespace.

We have tablespaces in acceptance and production that are being resized for
growth. Pctincrease is set at 0. Would it also help to coalesce the
tablespace? What are the benefits of this command?
Thanks,
Sandi
