Controlling 3270 Emulation
Controlling Display Sessions
Long Name
The unique identifier for each session. For instructions
for changing this option, see “Customizing Display
Sessions”.
Host Session
The name of the host session record in the
configuration file.
Host Domain
The symbolic domain name of the TCP/IP host used by
the session. If the session is disabled, this field is
blank. This field may be truncated on the right, if
necessary.
This name may correspond to a host computer that
supports direct TN3270 access over TCP/IP, or to a
communications product (such as the main SNAplus2
product) providing the TN server function on another
computer. For a TN server, the name shown is the
domain name or Internet address of the computer
where the TN server software is running.
If the System Administrator has given you permission
to override the configured domain name, you can
specify the -l option on the command line to specify
the name of the host to use for a given session. For
more information about overriding the configured host
domain name, see Appendix E, “Configuring TN3270
Hosts from the Command Line.”
LU Name
Identifies the 3270 LU or LU pool that is used by the
session.If the session is disabled, the name of the
configured LU or LU pool is shown (or blank if no LU
name is configured). If the session is active, the name
shown is the name of the actual LU used by the
session. If TN3270 protocols are being used, rather
than TN3270E protocols, the name of the configured
LU or LU pool is shown because the actual LU name is
not available.
Print Session
The session number for the associated printer session.
This field is blank if no printer session has been
associated.
