Starting the Guardian TN3270 Server
SWAP swap-name
specifies a swap volume, where swap-name is the swap volume name. Two
swap files are used. The swap files require a total of approximately 600 pages.
This space must be available on the swap volume. You can change the amount
of swap space allocated for the buffer segment with the -m command line option
described later.
The Guardian TN3270 Server ignores any IN or OUT file specification. However, if an
IN or OUT file is specified, it must be one of the following file types:
•
Odd-unstructured (code 180)
•
EDIT (code 101)
•
Process
•
Terminal
The following command line arguments are used by the Guardian TN3270 Server:
port
is a decimal number that specifies the TCP/IP port number over which connections
will be accepted. If the port number is 1023 or less, a super group user (255,nn)
must start the Guardian TN3270 Server. The port number must be unique among all
TCP/IP services accessing a single TCP/IP process. port number is required; there
is no default value.
tn32-options
specifies one or more command line options, which you enter separated by spaces
(spaces are not permitted within an option). For example, when using the -mpages
option, enter it as -m1020 for 1020 pages, with no spaces between the -m and the
1020.
-bsize
specifies the size of each socket read request in bytes. This parameter overrides
the default socket read size of 2048 bytes. Since the total PFS buffer size is
1 megabyte, and TN3270 Server posts a read for each TCP/IP session, the total
PFS buffer space is exhausted with 512 sessions active. Reducing the read size
potentially results in more I/O overhead but allows more than 512 reads to be
simultaneously active.
-cnumber
specifies NonStop mode operation. number is the CPU number (0 through 15)
on which to run the backup process. If this option is omitted, TN32SERV
operates as a single process.
