Combining with other attributes
The territory attribute is used only when creating a database.
In the following example, the new database has a territory of Spanish language and
Mexican nationality.
jdbc:derby:MexicanDB;create=true;territory=es_MX
You can use the
territory
attribute to specify that
collation is based on the territory instead of based on Unicode codepoint collation,
traceDirectory=path attribute
Function
Specifies a directory to which the Derby Network Client will send JDBC trace information.
If the program or session has multiple connections, the Network Client creates a separate
file for each connection. By default, the files are named
_driver_0
,
_driver_1
, and so
on. Use the
attribute to specify a file name for the trace file.
If the directory does not exist, Derby issues an error message. If you do not specify an
absolute path name, the directory is assumed to be relative to the current directory.
For more information about tracing, see "Network client tracing" in the Derby Server and
Administration Guide. See traceFile=path,
, and
for other attributes related to tracing.
