If it is there, cut and paste it (including the terminating semi-colon) to the front of the list otherwise, type it. In the path string, locate the JAVA_HOME path. Under System Variables, double click the Path variable to open it for editing. If this JAVA_HOME path is not the first path in the string, continue to the next step. If this JAVA_HOME path is the first path in the string, close the Environment Variables and System Properties dialog boxes and follow the instructions in Installing Oracle GoldenGate Director Server.

In the Environment Variables dialog box, look for the Path variable under System Variables.Ĭonfirm that the path to JAVA_HOME appears as the first path in the list of paths. Programs such as the Oracle database software place the path to their own JRE installations in the location that is expected by Oracle GoldenGate Director Server. These steps ensure that the JAVA_HOME path is in the expected location within the Path system variable. Leave the Environment Variables dialog box open and follow the instructions in Set the JAVA_HOME System Path. In the Variable Value box, type the correct path to the JRE.Ĭlick OK to set the path and close the dialog box. In the Variable Name box, type JAVA_HOME in capital letters.

The JAVA_HOME path should point to the location that you recorded when you installed the JRE. Under System Variables, look for the JAVA_HOME system variable. On the desktop (Windows 2000) or in the Start menu (Windows XP), right-click My Computer and then click Properties.Ĭlick the Advanced tab, and then click Environment Variables. These steps verify that the JAVA_HOME system environment variable points to the JRE that you installed, or creates the variable if absent.
