RE: ??? Linux/Oracle 8.1.7 2GB file size limit ???

I'd say file size limit/autoextend feature has been Oracle's dirty little secret for quite a while. For a very long period of time there was similar 4GB 'magic' barrier on Windows, that was allegedly fixed. Workaround for the problem was to create datafile 1 MB larger than the 'magic' number, and ether resize it using this trick or add another datafile to tablespace when the time comes (whenever MagicNumber or N x MagicNumber is close).

Despite rumours (of having fixed autoextend feature on Windows) I recently witnessed failed imports into Oracle caused by too small tablespaces that just wouldn't autoextend. Interestingly, import died "beautifully" cuz silently in the middle of job without _any_ errors, traces etc. Just gone.

There is also interesting myth here at the place where I work that systems tablespace autoextend feature ain't to be trusted as "it is known" to have caused intermittent data dictionary corruptions while code recompilation takes place under space "crunch" conditions...  

On slightly cynical side note: autoextend that doesn't - maps nicely into job safety ;-)
