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.
