Temporary segments in the temp area are always owned by sys. That is because the RDBMS kernel creates them for it's own purposes. What probably happen was some user who used the "three finger salute" on his/her PC & it just took PMON a little while to cleanup after them. An old trick to help alleviate that problem, try creating a table in the temp space that intentionally will not fit.  The failed to create table_name statement will force PMON to wake up. In your case the second user did it for you.

I had users complaining of select statements failing with "failed to extend temp segment" errors this morning. When I did a bit of digging around I noticed that SYS was holding onto 1 segment in the TEMP tablespace which was just under 15Gb (our temporary area almost full). I tried all the little tweaks (changing pctincrease to what it already was, coalescing etc) but to no avail, then about 5 minutes ago it released it all. Nobody was logged in as SYS.  

Is this a bug or is it my misunderstanding of how the temporary segments are used.  

TIA   PS. Thanks to all who responded to my RAID query.
