The table below provides more information about the statements.
For more information about the TCP/IP profile and the statements
described in this section, please refer to:

Configuring the
AXIS 5470e
Follow the instructions below to configure your AXIS 5470e using a
standard Web browser:
1. Start a Web browser, e.g. Internet Explorer or Netscape
Navigator.
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
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.
