In 9iR2 "execute sys.DBMS_SPACE_ADMIN.TABLESPACE_MIGRATE_TO_LOCAL('SYSTEM'); " will migrate SYSTEM DMT to LMT, provided all the tablespaces in the database are already LMT. There are other restrictions also (rollback, temp space, etc), for me it's not worth converting... :-) B -----Original Message----- From: DENNIS WILLIAMS [mailto:DWILLIAMS@xxxxxxxxxxxxx] Sent: Wednesday, March 17, 2004 11:02 AM To: 'oracle-l@xxxxxxxxxxxxx' Subject: RE: LMT SYSTEM Tablespace? - SUMMARY Stephen I hadn't considered the migration aspect mainly because I always try to avoid the migration aspect whenever possible. My strong preference, backed by people on this list that are a whole lot wiser than me, is to create the database in 9i, then export/import. But I agree that if I migrated, I would stick with DMT, and you may not have a choice anyway (I don't recall a method for converting a system tablespace from DMT to LMT). Part of my rationale for going LMT on 9i system tablespace is that since Oracle creates them that way by default, that configuration is probably tested more.

Ruth, Dennis, Tom & Hemant. Excerpts from the replies are below. Based on this, I think we are proceeding as we have been. That is to say, databases that are upgraded are keeping SYSTEM as DMT and new installs will get LMT for SYSTEM. For all other tablespaces, we are moving to LMT. Thanks! Stephen Andert >>>>>> I see no good reason why to change the SYSTEM tablespace to an LMT. I say wait until Oracle says it is required and then do it. Probably in 10G. It's working as it is, so I would leave it alone. >>>>>> I use LMT SYSTEM in 9.2.0.2 and 9.2.0.4 on Tru64 and Solaris without any issues >>>>>> Yes, in 9i LMT is the default for system tablespace and if that is LMT you cannot create a DMT. Haven't tried it, just quoting. >>>>>> In earlier versions the system tablespace was not supposed to be locally managed. In 9.2.0.x you can and probably should make it locally managed. I just did this on my production databases. ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- _____________________________________________________________________________________________________________ This electronic transmission and any attached files are intended solely for the person or entity to which they are addressed and may contain information that is privileged, confidential or otherwise protected from disclosure.
