Home -> Community -> Mailing Lists -> Oracle-L -> RE: RE: Change PCTINCREAE for SYSTEM Tablespace
Hi Tom,
Can you review my views in changing pctincrease value:
If i'm creating database manualy without dbassistant, The steps are,
1) CONNECT INTERNAL 2) CREATE DATABASE ( LOGFILES, A SINGLE DATAFILE FOR SYSTEM TABLESPACE AND other infos) 3) CREATING SYSTEM TABLESPACE 4) OTHER STEPS..... GOING ON...
Now why not i can change the PCTINCREASE at the step3?... In what way it'd affect the DB? And why we need to change sql.bsq instead?....
Hope that i didn't say anything incorrect. Let me know ur valuable reply...
Nirmal.,

Tom,
I agree and disagree with you, respectfully. Oracle does allow some changes to be made to sql.bsq and they always leave the option open to make changes after database creation and I don't see this request as all that odd. But for the most part if you do as recommended and leave the system tablespace to sys only you should not have a problem. That is until migration time!!

Kimberly,
I would agree with you if an experienced DBA makes the decision to change the storage parameters, and they absolutely know what the benfits would be.
Generally speaking though, I think changing anything in the SYSTEM tablespace is bad practice.

Actually, I would not ignore the storage parameters of the SYSTEM
tablespace.
There are legit reasons to change the pctincrease to 0. If you leave it at
50 then SMON (or PMON can't remember at the moment) will try to coalesce the
tablespace every time it wakes up. Its work it has to do that it really
does
not need to do. Better off scheduling to happen at your time schedule.

Ken,
Do yourself a favor. Ignore the SYSTEM tablespace storage params. The ONLY thing you should concern yourself in regard with the SYSTEM tablespace is if the file needs to extend itself because it is too full. All other storage parameters are created by Oracle at database create time and should not be changed.
For other tablespaces, you can change this parameter anytime after the tablespace has been created. It will not, however, change existing extents, but will be used when new extents are allocated.
Hope this helps.

Is there any way that I can change the PCTINCREASE for the SYSTEM tablespace without recreating the DB? For some reason the person who created the DB I am working on set PCTINCREASE to 50 (or didn't did not include this parameter). I am using this DB for a data conversion so there is no software connected to it and in turn no users on it.
Thanks,
