define_dlur_defaults
2.17 define_dlur_defaults
The define_dlur_defaults command defines a default Dependent LU Server (DLUS) and a backup default
DLUS. If a default DLUS or backup default DLUS is already defined, the command overrides the existing definition.
DLUR uses the default DLUS name when it initiates SSCP-PU activation for PUs that do not have an explicitly
specified associated DLUS. (To define a PU and its associated DLUS, use define_internal_pu for a local
PU, or define_*_ls (for the appropriate link type) for a downstream PU.)
The command can also be used to revoke a default DLUS or backup default DLUS, so that one is not de
fined.
2.17.1 Supplied Parameters
Parameter name Type Length Default
[define_dlur_defaults]
description character 31 (null string)
dlus_name character 17
bkup_dlus_name character 17 (null string)
dlus_retry_timeout decimal 5
dlus_retry_limit decimal 3
prefer_active_dlus constant
Supplied parameters are:
description
A text string describing the DLUR defaults. SNAplus2 uses this string for information only. It is stored in
the node’s configuration file, but SNAplus2 does not make any other use of it.
dlus_name
Name of the DLUS node that is to be the default. Specify 3–17 type-A characters that consist of a 1–8
character network name, followed by a period, followed by a 1–8 character DLUS node name. To revoke the
current default DLUS, so that no default DLUS is defined, do not specify this parameter.
bkup_dlus_name
Name of the DLUS node that is to serve as the backup default. Specify 3–17 type-A characters that consist of
a1–8 character network name, followed by a period, followed by a 1–8 character backup DLUS node name.
To revoke the current backup default DLUS, so that no backup default DLUS is defined, do not specify this
parameter.
dlus_retry_timeout
The interval in seconds between the second and subsequent attempts to contact the DLUS specified by the
dlus_name and bkup_dlus_name parameters. The interval between the first and second attempts is always 1
second.
Specify a value in the range 1– 65,535.
dlus_retry_limit
Retry count for contacting a DLUS. This parameter is used to specify the number of times SNAplus2 should
retry if it fails to contact the DLUS on the first attempt.
Specify a value in the range 1–65,534, or specify 65,535 to indicate that SNAplus2 should retry indefinitely
until it contacts the DLUS.
prefer_active_dlus
Specifies how SNAplus2 operates when it receives a negative RSP(REQACTPU) from DLUS, or is attempting
to reactivate a failed DLUR PU. Possible values are:
YES
