Kim Haase updated DERBY-3847:
-----------------------------
Attachment: ctunproper22250.html
DERBY-3847.diff
I'm attaching DERBY-3847.diff and ctunproper22250.html.
Please check the language here: I gathered from what Dag said that turning off
properties applies at the database-wide level. (I'm not sure it would have any
meaning at the system level.)
I also discovered when comparing the table here with the actual property topics
that there was no table entry for derby.database.sqlAuthorization, so I've
added one. It is a static property.

> Key: DERBY-3847
> URL: https://issues.apache.org/jira/browse/DERBY-3847
> Project: Derby
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 10.4.1.3
> Reporter: Kim Haase
> Assignee: Kim Haase
> Priority: Minor
> Attachments: ctunproper22250.html, DERBY-3847.diff

>
> The documentation of how to turn off Derby properties is spotty. Dag Wanvik
> reports that "I checked the code, and when you set a database property to a
> null value, that property is removed from the list of database properties;
> i.e. the situation is back to where you were before it was first set, so the
> built-in defaults apply again (or system properties if there are any)."
> The behavior for turning off user settings is slightly different and is
> documented in several places; it's the general case that seems to be missing.
> This information needs to be added to the description of Derby properties in
> the Tuning Guide, probably in the general topic "Derby properties"
> (http://db.apache.org/derby/docs/dev/tuning/ctunproper22250.html).
