This method is invoked by the MainReplicationService when a new MainReplication slice is added and has the effect of issuing a NEW_NODE VCommand and one NEW_SLICE VCommand for each service installed in the node hosting the new MainReplication slice. This allows services to propagate service specific information to their new slice

Specified by:

findSlice in interface PlatformManager

Throws:

IMTPException

ServiceException
