Concept of leasing in Weblogic(SOA Suite)

Some services are required to run only in a single member of a cluster.These are used basically for pinned services which are running on a single node of a cluster.The concept of leasing enable us to migrate the service to other node in case of failover.YOu can get more details on the same from the following documents

There are two type of leasing

1>Database leasing-Where in database is used for storing leasing information.

2>consensus leasing-where leasing information is stored in memory.

We will try to create a simple scenario and will see how leasing works in weblogic.

Requirement for this is that you should have a cluster with atleast two nodes.
