Kim Haase commented on DERBY-6305:
----------------------------------
Committed patch DERBY-6305.diff to documentation trunk at revision 1507340.
Merged to 10.10 doc branch at revision 1507341.
I'm backporting this fix to 10.10 and will do so for any existing overrides we
decide to document.
Any new overrides should have separate issues for both the feature and the
documentation.
> Tuning Derby information on optimizer overrides needs improvement
> -----------------------------------------------------------------
>
> Key: DERBY-6305
> URL: https://issues.apache.org/jira/browse/DERBY-6305
> Project: Derby
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 10.10.1.1
> Reporter: Kim Haase
> Assignee: Kim Haase
> Attachments: ctundepthoptover.html, DERBY-6305.diff
>
>
> The topic "Optimizer overrides" in the Tuning Derby manual talks about using
> the "-- DERBY-PROPERTIES" clause to specify overrides but doesn't include a
> link to the topic later in the manual, "Overriding the default optimizer
> behavior", that explains how to use the clause. This undoubtedly results in
> user confusion.
> The first topic is
> http://db.apache.org/derby/docs/10.10/tuning/ctundepthoptover.html; the
> second is
> http://db.apache.org/derby/docs/10.10/tuning/ctunoptimzoverride.html.
> I'll add the link, and I welcome additional suggestions on how to improve
> these topics.
