Missing uninstall components

In certain circumstances, some of the components required to perform an uninstall, as documented previously, may be missing. The required components for an uninstall are:

For SDK:
```
$SYBASE/uninstall/SDK/uninstall
```
For Open Server:
```
$SYBASE/uninstall/OpenServer/uninstall
```

For both Open Server and SDK, use the Java Runtime Environment:

$SYBASE/uninstall/JRE-1_4

If any of these components are missing, you can perform the uninstall using Java directly. To do so, use Java 1.4.2 or later, be sure that you have a Java Runtime in your path, or specify the full path to the Java executable. Then, enter the following command:

For SDK:

java -cp $SYBASE/uninstall/SDK/uninstall.jar run

For Open Server:

java -cp $SYBASE/uninstall/OpenServer/uninstall.jar run
