Administration Commands
define_node
Network node: Specifies whether local or domain resources can be optionally registered with central directory
server (CDS).
Possible values are:
YES
Register resources with the CDS.
NO
Do not register resources with the CDS.
mds_send_alert_q_size
Size of the MDS send alert queue. If the number of queued alerts reaches this limit, SNAplus2 deletes the
oldest alert on the queue. The minimum number of queued alerts is
2.
cos_cache_size
Size of the COS Database weights cache. This value should be set to the maximum number of COS de
finitions
required. Specify a value in the range 8–65,535.
tree_cache_size
Network node: Size of the Topology Database routing tree cache. The minimum is 8 entries. For an end
node or LEN node, this parameter is reserved.
tree_cache_use_limit
Network node: Maximum number of uses of a cached tree. When this number is exceeded, the tree is
discarded and recomputed. This enables the node to balance sessions among equal weight routes. A low
value provides better load balancing at the expense of increased activation latency. The minimum number of
uses is 1. For an end node or LEN node, this parameter is reserved.
max_tdm_nodes
Network node: Maximum number of nodes that can be stored in Topology Database. A value of 0 (zero)
indicates an unlimited number of nodes. For an end node or LEN node, this parameter is reserved.
max_tdm_tgs
Network node: Maximum number of TGs that can be stored in Topology Database. A value of 0 (zero)
indicates an unlimited number of nodes. For an end node or LEN node, this parameter is reserved.
max_isr_sessions
Network node: Maximum number of ISR sessions the node can participate in simultaneously. This parameter
is reserved for an end node or LEN node.
isr_sessions_upper_threshold
and isr_sessions_lower_threshold
Network node: These thresholds control the node’s congestion status, which is reported to other nodes in the
network for use in route calculations. The node state changes from uncongested to congested if the number of
ISR sessions exceeds the upper threshold. The node state changes back to uncongested when the number of
ISR sessions dips below the lower threshold. The lower threshold must be less than the upper threshold, and
the upper threshold must be lower than
max_isr_sessions. For an end node or LEN node, these parameters
are reserved.
isr_max_ru_size
Network node: Maximum RU size supported for intermediate sessions. If the supplied value is not a valid
RU size (as described in Systems Network Architecture: Formats), SNAplus2 will round the value up to the
next valid value. For an end node or LEN node, this parameter is reserved.
isr_rcv_pac_window
Network node: Suggested receive pacing window size for intermediate sessions, in the range 1–63. This
value is only used on the secondary hop of intermediate sessions if the adjacent node does not support adaptive
pacing. For an end node or LEN node, this parameter is reserved.
