ZPWY-MAP-DEF-TCP
maximum number of bytes that the TCP allocates for a server I/O buffer; it must be 
at least the size of the largest predefined server reply message.
For a TCP that runs the gateway requester program to support Pathway/iTS web 
clients, set the value of ZSERVERPOOL to 40,000 bytes. Otherwise, the 
suggested range is 10,000 to 30,000 bytes. The minimum value is 32 bytes. If you 
do not assign a value to this field, the default is 20,000 bytes.
The maximum useful value for ZSERVERPOOL is the length of the largest request 
or reply multiplied by the number of terminals that the TCP controls, and—if the 
program uses unsolicited-message processing (UMP)—the maximum concurrent 
UMP I/O operation multiplied by the maximum UMP message size. 
ZSTATS 
specifies whether to enable or disable the statistics collection mechanism within 
the TCP. ZSTATS can have the following values:
This field works in conjunction with the STATS TCP, STATS TERM, and STATS SC 
commands, which return statistics gathered by the TCP.
If you do not assign a value to this field, the default is ZPWY-VAL-OFF.
ZSWAP 
specifies the disk volume name for the temporary file formerly created and 
managed by the operating system for memory swaps of the TCP extended data 
segment. Allocation of this swap file is now handled by the Kernel Managed Swap 
Facility (KMSF) on behalf of the TCP, and the value of this field is not used. 
However, if you specify a value for this field, it must represent an existing device, 
or an error occurs.
ZTCLPROG 
is the name of the SCREEN COBOL object library file that the TCP uses to locate 
the screen programs for its terminals. The TCLPROG name is the portion of the 
SCREEN COBOL program library file name that precedes the letters COD. For 
example, if the object file name is $VOL.SUBVOL.POBJCOD, the object library file 
name is POBJ.
If you do not specify a node name, the default node for file-name expansion can be 
affected by the value you specify for the ZNODEINDEPENDENT field of the 
TS/MP START PATHWAY command. For more information on node independence, 
see the Pathway/iTS System Management Manual. 
Note. The pool space allocated for ZSERVERPOOL is the value you configure rounded 
off to the next-highest multiple of 4. 
ZPWY-VAL-OFF Deactivates the statistics collection mechanism.
ZPWY-VAL-ON Resets all STATS counters to 0 and then activates the 
statistics collection mechanism.
