All versions (MVS, VSE, and VM) implement a file transfer server function. The server, using my own file transfer protocol, seamlessly transfers files across MVS, VSE and VM/GCS systems. The following are the most salient features implemented in the file transfer server:
1. Simultaneous support for APPN (APPC LU6.2) and TCP/IP stacks: You can transfer files over APPN sessions (APPC LU 6.2) or TCP/IP connections. The choice is determined by the administrator and it is "invisible" to the end-user, the one doing the transfer. Because the integration of APPN and TCP/IP is so tight, it's possible to start the transfer over TCP/IP and finish it off over APPN!!
2. Unlimited number of simultaneous file transfers: The server supports unlimited number of active file transfers with one or more partners. The max number of simultaneously active partners is configurable by the administrator.
3. Automatic restart from point of interruption: The server automatically restarts interrupted transfers as soon as the network becomes available again. You do not have to do anything!! This will automatically take place even if the application is bownced in between.
4. Manual suspend-resume from either side: The user can manually suspend an active transfer. The suspended transfer can be restarted from either side.
5. All file types/record types are supported. You want to transfer your 16-meg spanned records file? No problem!!
6. Dynamic/Static Communications subtasks: The administrator can choose to spin a dedicated communication subtask for each transfer or have all transfers share a static one. This can be done on a host-per-host basis.
7. Data-blaster mode (MVS and VM versions only): In this mode, files are blasted using huge buffers. The end user basically defines how big those buffers are. The limit is 9999 64K buffers which means that your entire file can be up in the space boefore you know it!!
