I think even Oracle would disagree with you on that one. While it is unsupported to change anything in the sql.bsq script (except with Trusted Oracle where its required to actually get it to create a database) anything that is changeable after the fact is fair game. As a matter of fact, for all those GUI freaks out there;-) its one of the things you actually get to change when creating the SYSTEM tablespace using dbassist. Oracle had to pick a default so they chose 50. They also chose a default for the SGA but up until now it was pretty much a useless default. No where do they say that 50 for pctincrease is recommended or that it should stay that way. Don't forget, this is not SQL Server. We are encouraged by Oracle to set the system up for optimal performance.

Generally speaking though, I think changing anything in the SYSTEM tablespace is bad practice. Tom Mercadante Oracle Certified Professional -----Original Message----- Sent: Monday, December 17, 2001 8:45 PM To: Multiple recipients of list ORACLE-L 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. -----Original Message----- Thomas F Sent: Monday, December 17, 2001 7:45 AM To: Multiple recipients of list ORACLE-L 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. Tom Mercadante Oracle Certified Professional -----Original Message----- Sent: Monday, December 17, 2001 10:16 AM To: Multiple recipients of list ORACLE-L 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.
