The MAX_AVAILABLE element specifies the maximum number of available DVMs to be attached to a Web Service.
START <= MAX_AVAILABLE MIN_AVAILABLE <= MAX_AVAILABLE
To control the number of DVMs - and in effect the number of licenses - used by each application, you can split your licenses using MAX_AVAILABLE. By using a different fglprofile for each application, you can specify X licenses for application 1, Y licenses for application 2.
