Statement
Explanation
DATABUFFERPOOLSIZE
Defines the number and size of the data buffers. It is recommended that
you specify at least 160 data buffers and a buffer size of 32768 bytes
SMALLDATABUFFERPOOLSIZE
Defines the number of small data buffers. It is recommended that you
specify at least 256 small data buffers
TINYDATABUFFERPOOLSIZE
Defines the number of tiny data buffers. It is recommended that you
specify at least 256 tiny data buffers
KEEPALIVEOPTIONS
PSF relies on TCP to detect when a connection with a TCP/IP-attached
printer or an AXIS 5470e/570/670e is no longer available. When no data
has been exchanged between PSF and its connection partner, TCP sends
keep-alive probes to the connection partner periodically. These periodic
probes, called keep-alive transmissions, enable TCP to discover when a
connection is no longer usable even if the connection partner is abruptly
powered off or is no longer accessible through the network.
The frequency of keep-alive transmissions is controlled by the INTERVAL
parameter on the KEEPALIVEOPTIONS statement. The frequency applies
to all TCP applications that direct TCP to send keep alive transmissions.
The default frequency is after about two hours of inactivity.
We recommend that you specify a shorter interval than the default, such
as 10 minutes, for the interval between keep-alive transmissions.
Also, if any target host on you network requires that the keep-alive packet
contains data, specify SENDGARBAGE TRUE
GATEWAY
The Packet_size parameter of the GATEWAY statement defines the
maximum transmission unit (MTU) for the MVS host. The MTU size must
not exceed the maximum size that can be sent through the control unit; if it
does, transmission problems will occur.
The MTU size should be 2000 bytes and the MTU size for the MVS host
should be the same as the MTU size for the printer.
For values in the GATEWAY statement other than the packet size, specify
the values that are correct for your installation.
