How to uninstall RDQM if it is no longer required.

About this task

There are different procedures for uninstalling a high availability (HA) configuration, a disaster recovery (DR) configuration, or a combined DR/HA configuration.

Procedure

• To uninstall HA RDQM support if it is no longer required:
  1. Delete the RDQM HA queue managers in the HA group, see Delete an HA RDQM.
  2. Delete the RDQM HA group, see Delete the Pacemaker cluster (HA group).
  3. Log in as root or switch to superuser using the su command.
  4. If you configured a firewall, run the script MQ_INSTALLATION_PATH/samp/rdqm/firewalld/unconfigure.sh on each node to undo the firewall configuration. We must run this script as root.
