RE: Locally managed System Tablespace

[Gene Sais]

Personally I agree w/ Dennis, If it works, don't mess w/ it.  I am moving to LMT & Undo TBS when I upgrade to 9i from 8i. Gene >>> [EMAIL PROTECTED] 10/07/03 10:29AM >>> Thomas    To me, the main benefits are in manageability. I feel in most circumstances the performance benefits will be small.    As an approach, I have created all new tables in LMT with uniform extents over the last several years. I have moved tables that grow steadily to LMT. I have left a lot of older, static tables in dictionary-managed for the time being, but overall that is probably under 5% of the storage. My theory is don't mess with stuff that works. Dennis Williams DBA, 80%OCP, 100% DBA Lifetouch, Inc. [EMAIL PROTECTED] -----Original Message----- Sent: Monday, October 06, 2003 6:09 PM To: Multiple recipients of list ORACLE-L Is it really worth the effort to convert dictionary-managed system tablespaces to locally-managed in 9.2?  Ostensibly, I should see some performance improvements due to less recursive sql, etc; but from Googling/Metalink in looking for more info, it doesn't appear as though many sites have bothered to convert. The process is like this: a) Convert all dictionary-managed to LMTs. b) - cold backup    - DBMS_SPACE_ADMIN.TABLESPACE_MIGRATE_TO_LOCAL    - another cold backup Seems as though it might be better to wait until 10G when I assume Oracle will convert to LMT as part of the migration process; unless anyone can offer some compelling reasons? -------------------------------------------- Jeffery D Thomas DBA Thomson Information Services Thomson, Inc.
