Java Programming with Oracle SQLJ

1.4. Configuring Your Environment

This section describes how to configure your computing environment to develop and run SQLJ programs. Three environment variables must be set: ORACLE_HOME, PATH, and CLASSPATH. The ORACLE_HOME environment variable specifies the directory in which the Oracle software is installed. The PATH environment variable specifies a list of directories that contain the command-line utilities. The CLASSPATH environment variable specifies a list of Java class libraries and directories used by the various Java utilities.

1.4.1. The ORACLE_HOME Environment Variable

The ORACLE_HOME environment variable should be set to the directory where the Oracle software is installed. Many Oracle applications and utilities depend on the ORACLE_HOME environment variable to point the way to the Oracle software directory.

To set your ORACLE_HOME environment variable using Windows NT 4.0, use the System Properties dialog in the Control Panel. Figure 1-1 shows the ORACLE_HOME environment variable in the System Properties dialog.

To set your ORACLE_HOME environment variable using the Bash shell with Linux, add lines similar to the following to your .bash_profile file:

ORACLE_HOME=
installation_directory
export ORACLE_HOME

where installation_directory is the directory in which the Oracle software is ...
