There are no scripts or tools available to completely remove a Oracle NoSQL Database installation from your hardware. However, the procedure is simple. On each node (machine) comprising your store:
Shut down the Storage Node:
java -jar KVHOME/lib/kvstore.jar stop -root KVROOT
Note that if an Admin process is running on the machine, this command also stops that process.
Physically remove the entire contents of KVROOT:
> rm -rf KVROOT
Once you have performed this procedure on every machine comprising your store, you have completely removed the Oracle NoSQL Database deployment from your hardware.
