I vote for autoallocate - I've been using it for years in 8i to 11g databases on Windows, Linux, AIX & HPUX without a single problem and it's so much easier than trying to categorize thousands of unpredictable ERP tables into tablespaces with uniform sizes. Save yourself the trouble and just use autoallocate. Regards, Brandon Privileged/Confidential Information may be contained in this message or attachments hereto.
