Mamta A. Satoor commented on DERBY-855:
---------------------------------------

Couple comments
1)ctunoptimzoverride.html does a good job of cautioning the users to be careful 
about the correct syntax when using the -- DERBY-PROPERTIES clause. It will be 
good to point the users at this time to ctundepthoptover.html where they can 
verfiy if their overrides were correctly identified by the parser or not.
2)There shouldn't be any space between nested and loop when given as a value to 
joinStrategy.
3)The Tuning Guide has sections "Working with RunTimeStatistics"->"Analyzing 
the infromation". Under "Analyzing the information" page, can you add optimizer 
overrides to the existing list of Statistics timing, statement execution plan 
and optimizer estimates?

> Document optimizer overrides which were introduced in 10.2
