7.2 DLI Session Configuration
The DLI text configuration file used by the dlicfg program consists of the following sec-
tions:
• A “main” section which specifies the DLI configuration for non-session-specific
operations (described in the Freeway Data Link Interface Reference Guide)
• One or more additional sections, each specifying a protocol-specific session asso-
ciated with a particular Freeway serial communication link (port). Each link can
be configured independently of the other links. The BSC protocol allows multiple
sessions per link.
The protocol-specific session parameters can be divided into two groups:
• Client-related parameters are described in the Freeway Data Link Interface Refer-
ence Guide. For example, each session has an associated TSI connection name
which you also specify in your TSI configuration file, though multiple sessions
can use the same TSI connection.
• Protocol-specific link parameter values which are different from the defaults
shown in Ta ble 7 –1 (BSC 3270) or Tabl e 7–2 (BSC 2780/3780). These parameters
are optional in the DLI text configuration file. The
dlWrite Configure Link com-
mand also can perform protocol-specific configuration.
Figure 7–2 is an example DLI configuration file showing the “main” section and two
BSC 3270 sessions (the only difference for BSC 2780/3780 would be setting
protocol =
“BSC3780”
). The DLI client-related parameters are shown in typewriter type. The proto-
col-specific parameters are shown in
bold typewriter type. You need to include only
those parameters whose values differ from the defaults. Chapter 4 and Chapter 6
describe the link configuration options in detail.
The syntax for the BSC 3270 link configuration parameters is shown in Tab le 7 –1, along
with the defaults. The parameter names are case independent but are shown in upper
and lower case for readability. Tab le 7 –2 shows the same values for BSC 2780/3780.
