Only one correction, if you use DBCA to create the database, the SYSTEM
tablespace is LMT by default.
In 9iR2 you must specify the EXTENT MANAGEMENT LOCAL clause in the CREATE
DATABASE statement to create a LMT SYSTEM tablespace if manual DB
creation (using scripts).
And another catch is, if you explicitly specify EXTENT MANAGEMENT DICTIONARY in
the CREATE DATABASE, you will get an "invalid extent
management" error.
Also, if you decide to create SYSTEM LMT, make sure you specify the "DEFAULT
TEMPORARY TABLESPACE" in the CREATE DATABASE. And you no longer
can create DICTIONARY managed tablespaces in the database.

Thanks to all who replied. 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!

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.
