Hash joins and ORA-01652 unable to extend temp by...

A fewl times in the past few months we a have  had a standard "ORA-01652 unable to extend temp by..." error

which seemed to be occuring when a hash join inside a nested loop was reloading the tables over and over and over...

Sometimes was resolved with a "no hash join" hint on the SQL or building an index specifically for the sql being run or running it on a different day.

The most recent occurred while upgrading application software on our production database in restrict mode, nothing else was running. 

The dba doing this increased the TEMP tables space from 32G to 64G then to 96G with no luck; adding an index fixed it.

Howdy, Stranger!
