Port reservations shown on this panel may have been defined in one of several ways.
If you successfully executed the Refresh step, the ports shown originated from your existing port reservations MVS data set.
If you did not execute the Refresh step, the ports shown originated from the initial default set of port reservations.
The Add... button may have been used to add new port definitions.
msys for Setup services other than TCP/IP may have reserved ports. These port reservations were configured on the customization panels of another service and added to this port reservation list during Commit processing.
The ownership field is used to help you understand where the port reservation originated. If the port reservation originated from Refresh processing, from the default list, or due to an Add... , then the owner will be shown as TCPIP. If the port reservation originated from another msys for Setup service, then owner field will indicate the name of the other service.
If the owner is not TCPIP, you cannot edit or delete the port reservation from this panel. The port reservation originated from customization panels of another service. You need to delete or modify this reservation you need to do this from the other service's customization panels.
