Chapter 3. Operating NetView FTP V2.2.1 MVS - IBM

Common Storage Requirements
SVC Routine
Modules 5800 bytes
Automatic Areas 250 bytes
Dynamic Areas Size of FSBX required
The storage for the module resides in the PLPA.
This routine can run above the 16MB boundary.
The storage for these areas is allocated in the address space of the caller of the
SVC routine.
Static Common Service Area Requirements
Storage for the FSB is allocated by the queue handler in subpool 231. The number
of bytes allocated is:
(FSBSLOTS value x (1124 + 176)) + 40
This control block is allocated above the 16MB boundary.
The storage for this control block is freed when the queue handler terminates.
Dynamic Common Service Area Requirements
Storage for the FSBX is allocated when any component requires additional CSA
space.
The queue handler allocates its own additional CSA storage. The SVC routine allocates
additional CSA storage for the user interface routines and servers.
The storage is freed when it is no longer needed. The components of NetView
FTP V2.2.1 MVS must allocate additional CSA storage for an FSBX whenever a
queue handler command is to pass data to or from a NetView FTP V2.2.1 MVS
component and the RCB is not large enough to contain all the data.
