Configure the Discovery Protocol for a core group

The Discovery Protocol for a core group establishes network connectivity between a new core group member and the other members of that core group. Understand the concepts that are described in Core group Discovery Protocol. Then determine how long you want the Discovery Protocol to wait before it recalculates the set of unconnected core group members and attempts to open connections to those members.

Overview

To change wait interval for the Discovery Protocol:

Procedure

1. In the administrative console, click Servers > Core groups > Core group settings > core_group_name.

2. Under Additional Properties, click Custom Properties.

3. Change the value that is specified for the IBM_CS_UNICAST_DISCOVERY_INTERVAL_SECS custom property.

   If the IBM_CS_UNICAST_DISCOVERY_INTERVAL_SECS property already exists, click on the property name and specify the new interval length, in seconds, in the Value field.

   If this property does not already exist, click New and create it:

   1. In the Name field, specify IBM_CS_UNICAST_DISCOVERY_INTERVAL_SECS.

   2. In the Value field specify the length of time, in seconds, you want the Discovery Protocol to wait before it recalculates the set of unconnected core group members and attempts to open connections to those members.

4. Click OK and then click Review.

5. Select Synchronize changes with nodes, and then click Save.

6. Restart all members of the core group.
