Re: temp tablespace colesce

Joan's problem/solution of setting "hash_multiblock_io_count=2" sounds a lot like this from metalink.

When a user's temporary tablespace is type=temporary and extent size < hash_multiblock_io_count an ORA-3232 is raised when an attempt is made to perform a hash join. if the HASH_MULTIBLOCK_IO_COUNT is NOT set or = 0, then set it to 2 or 8
