NETBIOS REQUIREMENTS FOR AST-BSC/SNA GATEWAYS
|
|||
|
|
|
|||
|
|
|
|||
|
|
The following technical bulletin was written for anyone who
|
|||
|
|
wishes to install AST-SNA and AST-BSC Gateway products on a
|
|||
|
|
NETBIOS compatible LAN (Local Area Network). It is assumed that
|
|||
|
|
the reader is familiar with 3270 environments and has read the
|
|||
|
|
AST-SNA or AST-BSC Gateway product manual.
|
|||
|
|
|
|||
|
|
AST-SNA and AST-BSC Gateway products allow any "NETBIOS"
|
|||
|
|
compatible network to communicate to a mainframe. A "Gateway PC"
|
|||
|
|
emulates a 3274/76 remote control unit and distributes available
|
|||
|
|
LU (Logical Unit) sessions from the mainframe to individual nodes
|
|||
|
|
on the LAN. To accomplish this, AST-SNA and AST-BSC Gateway
|
|||
|
|
products must first acquire available NETBIOS sessions on the
|
|||
|
|
LAN.
|
|||
|
|
|
|||
|
|
NETBIOS sessions allow the PCs to communicate over the network to
|
|||
|
|
the various devices they are utilizing. For instance, if a PC has
|
|||
|
|
access to drive C:, D:, and the printer attached to LPT1: on the
|
|||
|
|
server PC, it must have at least three sessions available on the
|
|||
|
|
network. One session for drive C:, one session for drive D: and
|
|||
|
|
one for the printer.
|
|||
|
|
|
|||
|
|
AST-SNA and AST-BSC Gateway products also require NETBIOS
|
|||
|
|
sessions available to enable communications between the "Gateway
|
|||
|
|
PC" and the other nodes on the network. For each mainframe to LU
|
|||
|
|
session established, there must be a corresponding NETBIOS
|
|||
|
|
session on the network.
|
|||
|
|
|
|||
|
|
AST NETBIOS Option allows the user to configure the number of
|
|||
|
|
concurrent NETBIOS sessions allowed on individual PCs through the
|
|||
|
|
"ASTPRO.COM" personality program. For details on running the
|
|||
|
|
program, refer to the manual "AST-NETBIOS Option" part number
|
|||
|
|
000303-001 C, October 1986, section 2.4 page 2-10.
|
|||
|
|
|
|||
|
|
Failure to configure enough sessions on NETBIOS will not allow
|
|||
|
|
AST-SNA or AST-BSC Gateway products to establish any host to LU
|
|||
|
|
sessions on the network. The gateway products will report an
|
|||
|
|
error "UINITLU TERMINAL NUMBER XX NOT CONFIGURED", where XX is
|
|||
|
|
any of the configured host to LU session numbers unable to
|
|||
|
|
acquire an open NETBIOS session.
