START RTR

Qualifiers

/ASTLM=ast-limit
/ASTLM=(max-links + max-processes)

2

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 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

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.
