3 Messaging Manager Replication Screen

Replication is the process used to ensure several instances of databases are kept synchronized. This chapter explains the Messaging Manager replication process.

This chapter contains the following topics.

Messaging Manager Replication

Configuring Messaging Manager replication enables you to replicate MM data only to nodes which are running MM. Setting up replication has three parts:

  1. Configuring Messaging Manager replication

  2. SMF database synchronization across the platform

  3. Messaging Manager run time synchronization.

For more information about replication, see SMS User's Guide.

Configuring MM replication

The Replication tab on the Messaging Manager Replication screen enables you to specify which nodes receive Messaging Manager data through replication.

SMF database synchronisation

The replication process copies all the updates to the SCP database on each SLC, as defined by SMS Node Management, Table Replication tab.

Replication configuration is set up by clicking the Create Config File button in SMS replication screen. For more information about the SMS replication process, see SMS User's Guide.

MM run time synchronization

On a regular basis MM Multigate checks MM database tables for any changes made. When found, the differences are extracted and copied to the run time Messaging Manager configuration. This technique allows for Messaging Manager configuration to continuously be updated without the need to stop and restart.

For more information about how to configure the configuration checking period, see loadIntervalSeconds parameter in MM Technical Guide.

Messaging Manager Replication Screen

The Messaging Manager Replication screen enables you to configure which nodes receive MM data.

It has only one tab, the Replication tab.

Accessing the Messaging Manager Replication screen

Follow these steps to open the Messaging Manager Replication screen.

  1. Select the Services menu from the SMS main screen.

  2. Select Messaging Manager.

  3. Select Replication.

    Result: The Messaging Manager Replication screen displays.

Replication

The Replication tab enables you to specify which nodes (SLCs) should have Messaging Manager data replicated to them.

Configuring Messaging Manager replication

Follow these steps to flag the Messaging Manager nodes to be included in replication.

  1. Open the Messaging Manager Replication screen.

  2. Review the listed Messaging Manager nodes. In each Replicated check box, perform one of the following actions:

    • Select, to have the node replicated

    • Deselect, to stop the node from being replicated

  3. Click Apply to save to the database.

    Result: SMS will update the "Allocated Replication Groups" in "Table Replication" for all selected nodes.
