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 work around 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"
