Setting up the Db2 Configuration File
In order for Jopaz to be able to connect to Db2 and to perform SQL operations, you must set a few properties in the db2.properties file. Other than the parameters mentioned in this section, you can also specify JDBC and SQLJ properties in the db2.properties file.

Parameter Name | Mandatory | Description
user | Yes | Sets up the userid to connect to Db2. This user must require access on Db2 to perform SQL operations.
password | No | Sets up the password for the Db2 user. This property is not mandatory, because the recommended method to store your password is through the Jopaz Db2 password encryption capability.
databaseName | Yes | Sets up the Db2 database location name to connect to the specific Db2 system. For example: DAEFDB2D.
serverName | Yes | Specifies the fully qualified domain address of the z/OS system.
portNumber | Yes | Specifies the TCP/IP port number, which identifies the specific Db2 subsystem.
