Was the prohibitition on placing LOB's into tablespaces with automatic segment space
management only a bug. I ask because the description of "auto" segment space
management includes the following restrictions
Restrictions on AUTO:
* You can specify this clause only for permanent, locally managed tablespace.
* You cannot specify this clause for the SYSTEM tablespace.
* You cannot store LOBs in AUTO segment-managed tablespaces.
------------------------------------------------------------------------------------------------------------------------
The above is from the 9.0.1 SQL manual.
One usually associates a bug with something the manual says one can do, but one
cannot. I've not seen the 9.0.2 manual. Are the restrictions lifted?
In a single instance environment unless you are doing something out of the ordinary,
use of the clause will probably be detrimental.

The first time we tried importing our 8.1.5 [OPS] database
into 9.0.1 and 9.2.0.1 with
EXTENT_MANAGEMENT Local for ALL tablespaces
SEGMENT_SPACE_MANAGEMENT Auto
we found that tables with LOB segments could not be created. This was a 9.0.1 bug
which was expected to have been fixed in 9.2 [I believe it was Bug 1626182, referenced
in Note 159078.1]
However, after going to 9.2.0.2, I WAS able to create
such tables in the database.
[the Patchset Notes include a reference to Bug 2326066. Unfortunately, I can't see
either bug on MetaLink to verify if both are the same issue]
9iRAC strongly recommends SEGMENT_SPACE_MANAGEMENT Auto
instead of using Free_Lists and Free_List_Groups. [Part 3, Appendix B of the 9iRAC
Deployment and Performance manual].
Are there any real-life experiences / gotchas with LOB Segments in Locally Managed
Tablespaces and Segment_Space_Management Auto ? There seem to be a number of bug-fixes
for Segment_Space_Management=AUTO in the 9.2.0.2 PatchSet Release Notes.
