RE: Automatic Space Management Observation

This has nothing to do with ASM which only exists on 10g.

Nor do I believe that what you are seeing is directly related to ASSM in 9+.
It looks to me that your tablespace was created using auto-allocate as the
allocation method and the behavior you described is in line with it.  It
would be helpful if you had posted the create tablespace DDL or the
dba_tablespaces values for the tablespace.

All,
 

I finally turned ASM on in my 9.2 database.  The tablespaces were created
with no defaults - no uniform extent sizes.

 

Oracle created the tables all with 1M extent size.  When loading a table, I
notice that the first 64 extents were all 1M in size.  The last 9 extents
are all 8M in size.

 

So, is this how ASM works?  Just curious if anyone else has had similar or
different experiences?
