Uninstall the RPM

You will have to uninstall all the RPMS on every machine you installed them; Assuming than you installed all the packages on a single machine:

bash# rpm -e cvebrowser-tools cvebrowser-docs XXX
warning: /opt/cvebrowser/etc/create_tables.sql saved as /opt/cvebrowser/etc/create_tables.sql.rpmsave

You will have to erase the data directories by yourself after uninstall the RPMS.
