Restoring modules

Restore modules to their previous version.

Restore the modules in the order in which they displayed, starting from first to last. To avoid dependency issues, restore the main components or managers before their sub-components. For example, restore the Event Processing Manager before its sub-component, Event Property Tagger. Refer to the Module Manager documentation for more complete information about module rollback. This document is in the documentation directory of the installation path (for example, /opt/APG/Doc).

Prerequisites

• Identify all modules that can be restored by using the manage-modules.sh list restorable command.
• Make sure you have a login with root or system administrator privileges to restore modules.

Procedure

1. Type the command for your operating system from the M&R platform installation directory:

   Operating system	Command
   UNIX	<INSTALL_DIR>/bin/manage-modules.sh restore <module_identifier> [<module_instance>]

2. Answer any questions.
