SNA Server enforces the rules that govern active sessions between communicating partners on an SNA network.
The computer running SNA Server can select some of these session protocols — such as request/response control modes, bracket usage, and pacing — when you activate a session. Specific combinations of these selectable protocol options are called profiles.
TS profiles refer to transmission control options, while FM profiles refer to data flow control and function management data options.
When a session is activated, its TS and FM profiles are specified by using parameters in the appropriate session activation request and response (ACTPU, ACTLU, BIND).
Table 3.4 specifies the TS and FM profiles supported by each of the SNA Server session types.
Table 3.4 TS and FM Profiles Supported in SNA Server Sessions
Session type | TS Profiles | FM Profiles |
SSCP-LU session | 1 | 0 |
SSCP-PU session | 1 | 0 |
3270 display and printer PLU-SLU session | 3 | 3 |
LU 6.2 PLU-SLU session | 7 | 19 |
LUA PLU-SLU session | 2, 3, 4 | 2, 3, 4, 7, 18 |
The following sections describe the TS and FM profiles that SNA Server supports.
