ZMAXREPLY

is the maximum number of bytes permitted for an outgoing SEND message or a
server reply message.
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, set the value of ZMAXREPLY to 32000. Otherwise, set this value to the
larger of:
The longest outgoing message (in bytes) from any SEND verb from any TERM
object under control of this TCP
The longest reply (in bytes) possible from any server replying to a SEND verb
from any TERM object under control of this TCP
The TCP uses this number and the value for the ZMAXTERMDATA field to allocate
the size of the context areas (Slot 0 and Slot 1) for its TERM objects.
If you do not assign a value to this field, the default is 2000 bytes.

ZMAXSERVERCLASSES

is the maximum number of server classes with which the TCP can communicate
simultaneously. Valid values range from 0 through 4095.
If you do not assign a value to this field, the default is the number of server classes
specified in ZPWY-DDL-DEF-PATHWAY.

ZMAXSERVERPROCESSES

is the maximum number of links a TCP can have to all servers in all server classes.
Valid values range from 0 through 4095.
If you do not assign a value to this field, the default is the number of server
processes specified in ZPWY-DDL-DEF-PATHWAY.

ZMAXTERMDATA

specifies the number of bytes that the TCP allocates for context data for each
terminal. The TCP uses this value and the value of ZMAXREPLY to determine the
size of a terminal's slot areas. (Slot 0 and Slot 1 are of the same size.)
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, set the value of ZMAXTERMDATA to 200000.
The maximum value for this field is 2,147,483,647 bytes. The minimum value is
2804 bytes if the ZNONSTOP field is set to ZPWY-VAL-NONSTOP1. If you enter a
value less than 2804 bytes, the PATHMON process automatically increases the
value to the minimum value. There is no minimum value if ZNONSTOP is set to
ZPWY-VAL-NONSTOP0.
After running the TCP, check the value for ZMAXSIZE in ZPWY-DDL-STATS-
TERM2 to find the actual size of the context data area that the TCP allocates for a
terminal.
