Removing the AUTOLOGON Value
The AUTOLOGON value can be removed from the line, PU, and LU with an ALTER
command by specifying a null string (””) as the value for AUTOLOGON.
Caution Do not use use the AUTOLOGON attribute to specify a logoff record. If AUTOLOGON specifies either a
LOGOFF ESS record or an ORDER ESS record with STATIC OFF specified, SNAX/XF issues the ESS
system error S0006 and the request fails. If the attribute refers to an INITSELF-RECEIVED request,
SNAX/XF issues the ESS system error S0049, and the request fails (see Appendix B for an explanation of
these messages).
ESSTABLE Attribute The syntax for the ESSTABLE attribute is as follows:
ESSTABLE ess-table-name
When the LU (terminal) sends an SNA character-coded command or INIT-SELF
command, SNAX/XF uses the ess-table-name value to search for the ESS table that
should be associated with the LU. ess-table-name must be the name of an
existing ESS record in the current LUNS SET table.
ADD LINE
When the ESSTABLE attribute is specified by the line object, ess-table-name serves
as a default value for all LUs subordinate to the line, with the following exception:
The value is not propagated to those LUs that have an ESSTABLE value specified
by the LU object.
ADD PU
When the ESSTABLE attribute is specified by the PU object, ess-table-name serves
as a default value for those LUs subordinated to that PU, with the following exception:
The default value is not propagated from the PU to those LUs that have an
ESSTABLE value specified be the LU object with an ADD LU command.
ADD LU
When the ESSTABLE attribute is specified at the LU level, the ess-table-name
overrides any value specified by the ESSTABLE attribute in the line or the PU object.
Switched Floating LUs
The default value is not propagated from the line, LU, or PU object to switched
floating LUs. For switched floating LUs, the ESSTABLE value must be specified with
an ADD PU command (which propagates the value to the switched floating LU), or
with an ADD LU command.
Note that if the ESSTABLE attribute is not specified for switched floating LUs, the
default value for the switched floating LUs is OFF.
