Hi, I am trying to generate an optimizer trace, with the following
properties:
derby.language.OptimizerTrace=true (not sure if its case sensitive)
derby.language.optimizerTrace=true
derby.language.optimizerTraceHtml=true
I see optimizerTrace and optimizerTraceHtml as members of the OptimizerImpl
class. But this does not seem to generate a stack trace for the optimizer.
The only thing I was able to get to work was:
derby.debug.true=DumpOptimizedTree //this only dumps the tree, but not the
tracing
How could I get the optimizer to trace itself in derby.log or some file?
(also derby in general).
Not sure if this is a question for derby-dev actually?
Thanks
