The Discovery Protocol for a core group establishes network connectivity between a new core group member and the other members of that core group.
Before you begin
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.Why and when to perform this task
You might want to perform this task if you are trying to tune the discovery protocol behavior for a core group. The default value of 60 seconds, which is set during the WebSphere Application Server installation process, provides an acceptable process detection time for most situations.To change wait interval for the Discovery Protocol:
Steps for this task
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:
Result
After the servers restart, the core group members all run with the new Discovery Protocol setting.Related concepts
