START RTR

Qualifiers

/ASTLM=ast-limit

/ASTLM=(max-links + max-processes)22 + 10 = default ast-limit (D) Specifies the AST limit for the RTR ACP.

The value for ast-limitmust 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 0-node configuration, a router node needs an ASTLM of at least 45 ( 5 + (20 22) ).

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-limitis automatically calculated, based on the value of /LINKS and /PROCESSES.

/BIOLM=io-buffered

/BIOLM=(max-links + max-processes)22 + 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-bufferedis 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-limitis 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-limitis ten milliseconds. When the time expires, the RTR ACP is deleted.

The default value is established at system generation time.

A time-limitlimit of 0 indicates that CPU time is not restricted.
