The syntax for the command to launch the dblook utility
is:
dblook -d databaseURL [options]
The value for databaseURL is the complete URL
for the database. Where appropriate, the URL includes any connection attributes
or properties that might be required to access the database.
For example, to connect to the database 'myDB', the URL would simply be 'jdbc:derby:myDB'; to
connect using the Network Server to a database 'C:\private\tmp\myDB' on a
remote server (port 1527), the URL would be:
'jdbc:derby://localhost:1527/"C:\private\tmp\myDB";user=someusr;password=somepwd'
As with other utilities,
you must ensure that no other JVMs are started against the database when you
call the dblook utility, or an exception will occur and will
print to the dblook.log. If this exception is thrown, the dblook utility
will quit. To recover, you must ensure that no other applications
running in a separate JVM are connected to the source database. These connections
need to be shutdown. Once all existing JVMs running against the database have
been shutdown, the dblook utility will execute successfully.
You can also start the Network
server and run the dblook utility as a client application
while other clients are connected to the server.
