If you have installed the SAP Portal driver on a server that does not have a Java Virtual Machine (JVM) installed on it, you receive the following error when trying to uninstall the driver:
No Java virtual machine could be found from your PATH environment variable. You must install a VM prior to running this program.
The problem only occurs if you install the SAP Portal driver on a server that does not have Identity Manager or the Remote Loader installed on it.
The workaround is to install the driver on a server with Identity Manager or the Remote Loader, or install the JVM and add the installation location to the PATH variable.
Linux/UNIX: To add the JVM to the PATH variable:
From a command line, enter export PATH=<JAVA-HOME-PATH>/bin/:$PATH.
Run the uninstall script for the Sentinel driver, where the JAVA-HOME-PATH is the Java or JRE installation location.
Windows: To add the JVM to the PATH variables, use the following command:
"Uninstall Novell Identity Manager Drivers for SAP.exe" LAX_VM "<JAVA-HOME-PATH>\bin\java.exe"
For information about uninstalling the driver, see Uninstalling the Metadirectory Server
in the Identity Manager 4.0.1 Framework Installation Guide.
