Starting ij using properties

You set ij properties in any of the following ways:

by using the -D option on the command line
by specifying a properties file using the -p propertyfile option on the command line

Remember: ij property names are case-sensitive, while commands are case-insensitive.

The following examples illustrate how to use ij properties:

To start ij by using a properties file called ij.properties, use a command like the following (with the addition of the file paths):

java -jar derbyrun.jar -p ij.properties

To start ij with a maximumDisplayWidth of 1000:

java -Dij.maximumDisplayWidth=1000 -jar derbyrun.jar

To start ij with an ij.protocol of jdbc:derby: and an ij.database of sample, use the following command:

java -Dij.protocol=jdbc:derby: -Dij.database=sample derbyrun.jar

To start ij with two named connections, using the ij.connection.connectionName property, use a command like the following (all on one line):

java -Dij.connection.sample=jdbc:derby:sample 
-Dij.connection.History=jdbc:derby:History 
-Dderby.system.home=c:\derby\demo\databases
-jar c:\derby\lib\derbyrun.jar

To see a list of connection names and the URLs used to connect to them, use the following command. (If there is a connection that is currently active, it will show up with an * after its name.)

ij version 10.3
ij(HISTORY)> show connections;
HISTORY* -    jdbc:derby:History
SAMPLE -     jdbc:derby:sample
* = current connection
ij(HISTORY)>
