-------------------------------------------
Release Note text attempt:
PROBLEM:
With version 10.2.1.6 an incompatibility with 10.1.1.0 was introduced - since
revision 393003, the undocumented, non-standard but previously public method,
getProperties for Client DataSources was removed for security reasons. This
leaves only the setConnectionAttributes method available for creating or
shutting down a database. For instance, in Geronimo the getProperties method
was previously used to inquire and set whether a create=true was set for a
database.
It would be helpful if ClientDataSource could have the same methods available
as EmbeddedDataSource:
setCreateDatabase (String)
getCreateDatabase()
setShutdownDatabase (String)
getShutdownDatabase()
SYMPTOM
The getProperties() method is no longer available, nor are alternative methods
except the setConnectionAttributes(String) and getConnectionAttributes()
methods.
CAUSE
The getProperties() method was removed as part of DERBY-446; make
ClientDataSource use public getter and setter methods as standard for Java bean
properties. It should not have been public.
SOLUTION
4 new public methods were created for ClientDataSource:
setCreateDatabase (String)
getCreateDatabase()
setShutdownDatabase (String)
getShutdownDatabase()
These methods should behave similarly to the ones in Embedded, i.e. only valid
value for setCreateDatabase is "create", and for setShutdownDatabase is
"shutdown". In essence, at connection time, if set to a valid value, the
property is passed on to the server side with the ConnectionAttributes.
Note, that the result for setting contradicting properties for createDatabase
and ShutdownDatabase, whether through setCreateDatabase("create") and
setShutdownDatabase("shutdown") or via setConnectionAttributes("create=true")
or ("shutdown=true") is undefined.
WORKAROUND
set and get of ConnectionAttributes can be used to create or shutdown a
database.
INCOMPATIBILITIES: none from 10.2.1.6 to 10.3
REQUIRED CHANGES TO EXISTING APPLICATIONS: there are no required changes.
Applications can now use the setCreateDatabase, getCreateDatabase,
setShutdownDatabase, and getShutdownDatabase methods with DerbyNetClient as
well as with Embedded.

> Project: Derby
> Issue Type: Bug
> Components: Network Client
> Affects Versions: 10.2.1.6, 10.2.2.0
> Environment: All
> Reporter: Matt Hogstrom
> Assigned To: Myrna van Lunteren
> Fix For: 10.3.0.0
>

>
>
> Not sure exactly where this was deprecated but on Client DataSources it
> appears that the getProperties method was made private. In Geronimo we were
> using this to inquire and set whether a create=true was set for a database.
> We are moving from 10.1.3.1 to 10.2.1.6 (or perhaps 10.2.2.0) for our next
> version which we are targetting for April of this year.
> Is it possible to add the following methods on the ClientDataSource:
> setCreateDatabase (String)
> getCreateDatabase()
> setShutdownDatabase (String)
> getShutdownDatabase()
> as they are on the EmbeddedDataSource?
