START RTR
Qualifiers
/ASTLM=ast-limit
/ASTLM=(max-links + max-processes) 2 + 10 = default ast-limit (D)
Specifies the AST limit for the RTR ACP.
The value for
ast-limit
must include five for RTR ACP mailbox reads and timer
scheduling and a minimum of two per DECNET logical link maintained by RTR.
For example, in a 20-node configuration, a router node needs an ASTLM of at
least 45 ( 5 + (20 2) ).
In systems where a lot of traffic is expected, defining additional ASTLM quota
will enable lookahead I/O to be booked to channels without RTR ACP being held
up in a resource wait.
The default value of
ast-limit
is automatically calculated, based on the value of
/LINKS and /PROCESSES.
/BIOLM=io-buffered
/BIOLM=(max-links + max-processes) 2 + 10 = default io-buffered (D)
Specifies the maximum number of system-buffered I/O operations that the RTR
ACP can have outstanding at any one time.
The default value of
io-buffered
is automatically calculated, based on /LINKS
and /PROCESSES values.
/BYTLM=buffer-limit
/BYTLM=1,000,000 (D)
Specifies the maximum amount of memory, in bytes, that the RTR ACP can use
for buffered I/O operations or temporary mailbox creation.
This should be sufficiently large to account for lookahead DECNET traffic.
The default for
buffer-limit
is 1,000,000.
/CLUSTER
/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.
If neither
/NODE
nor
/CLUSTER
is specified then the command is executed on the
nodes specified by the latest
SET ENVIRONMENT
command. If no
SET ENVIRONMENT
command has been entered then the command is executed only on the node where
the command was issued.
Note: In environments that do not support clustering, use of the /CLUSTER
qualifier will cause the relevant command to be executed on the local node only.
/CPULM=time-limit
/CPULM=default-time-limit (D)
Specifies the maximum amount of CPU time (in delta time) allocated to the RTR
ACP. The unit of
time-limit
is ten milliseconds. When the time expires, the RTR
ACP is deleted.
The default value is established at system generation time.
A
time-limit
limit of 0 indicates that CPU time is not restricted.
