You can also configure your system to automatically boot all databases
in the system when it starts up; see "derby.system.bootAll" in the . Because of the time needed
to boot a database, the number of databases in the system directory affects
startup performance if you use that configuration.
Once a database has been booted within a system,
it remains active until the system
has been shut down or until you shut down the database individually.
When boots a database,
a message is added to the log file. The message includes the version
that the database was booted with, for example:
2008-09-18 16:43:54.992 GMT:
Booting version The Apache Software Foundation -
- .2.0 - (689064): instance a816c00e-011c-7658-a92a-fffff0cfee85
on database directory C:\sampledb
The number of databases running in a system
is limited only by the amount of memory available in the JVM.
