Subject [jira] [Updated] (DERBY-6305) Tuning Derby information on optimizer overrides needs improvement
Date Mon, 05 Aug 2013 15:48:49 GMT

     [ https://issues.apache.org/jira/browse/DERBY-6305?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rick Hillegas updated DERBY-6305:
---------------------------------

    Attachment: DerbyProperties.html

Attaching DerbyProperties.html. This is the first rev of a spec describing the --derby-properties
and how they are used. I am not confident that I have uncovered all of them. Further revs
of this spec may be necessary if we discover other --derby-properties.

> 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.
