Uninstalling Petals ESB Hazelcast Registry

According to Debian policies, Petals ESB Hazelcast Registry packages can be uninstalled with or without purging configuration files, with your favorite Debian tools (synaptic, apt-get, dpkg).

In addition to the runtime files, the purge will remove following directories containing some configuration or working files:

• /etc/petals-registry/member-enable
• /var/lib/petals-registry
• /var/log/petals-registry
• /var/run/petals-registry

The dedicated Petals system user and group are also removed when purging packages. The Petals ESB Hazelcast Registry node configurations (/etc/petals-registry/member-available) are never removed except the sample one, to be reused eventually.

All Petals ESB Hazelcast Registry nodes declared into /etc/petals-registry/member-enable will be automatically stopped during the uninstallation process. If you have started manually other Petals ESB Hazelcast Registry nodes, you must stop them before to launch the uninstallation process.
