#### Function

This property is similar to the ij.protocol property. The only difference is that it associates a name with the value, thus allowing you to define and use more than one protocol. (See Connect.)

#### Syntax

    ij.protocol.protocolName=protocolForEnvironment

#### Example

    D:>java -Dij.protocol.derby=jdbc:derby:
    -Dij.protocol.emp=jdbc:derby: org.apache.derby.tools.ij
    ij version 10.2
