RE: System Tablespace and Autoextend
Actually, SYSTEM is one of the only tablespaces I like to have it set on. While I originally set it to autoextend when I was doing an upgrade I left it active on the grounds that while I know how to recover if by some chance one of my datafiles runs out of space, I'm uncertain as to the implications of SYSTEM needing to extend and failing. -Original Message- Sent: Thursday, November 07, 2002 1:09 PM To: Multiple recipients of list ORACLE-L I use AUTOEXTEND and it has been extremely helpful to me in managing growth. However, my policy is not to use autoextend for SYSTEM, rollback tablespace, or temp tablespace. SYSTEM (for me) is relatively stable. The only time I have significant growth in SYSTEM is during an upgrade. For rollback and temp tablespaces, I don't want to throw away diskspace on unreasonable or abnormal usage.

RE: System Tablespace and Autoextend
Title: RE: System Tablespace and Autoextend I have read complaints about SYS.IDL% objects having PCTINCREASE 50 and space problems when they extend, in the forums. I went to check and mine are already set to 0 along with 2147483645 MAXEXTENTS. I created a TAR and verified with Oracle that altering storage options for sys/system objects was supported as long as they were not decreased below the defaults. The exception was that if you have a large MAXEXTENTS on the object then you could decrease PCTINCREASE or set it to 0. I have checked NEXTEXTENT values and there are some objects which aren't ready to extend but when/if they do (probably result of migration) they will consume 250mb which to me is obviously excessive. I haven't taken any action of course after all it is SYSTEM!, but PCTINCREASE of 50 on objects that have grown a couple times does inevitably invite space consumption issues at some point in the future. -Original Message- From: Hately, Mike (NESL-IT) [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 07, 2002 12:24 PM To: Multiple recipients of list ORACLE-L Subject: RE: System Tablespace and Autoextend FWIW I'd go with Dennis here.

Re: System Tablespace and Autoextend
