MPE Commands
SNACONTROL START
error will occur. If you do not specify an account for a
link-level trace file, the file will automatically be
written to the SYS account.
If you specify a file that does not exist, NMS builds a
new one and opens it to record tracing. If you specify an
existing file that NMS does not currently have open to
record tracing, NMS will overwrite the file’s previous
contents; no warning is issued. If you specify an
existing file that NMS already has open to record
tracing (even if it is recording events from a different
subsystem), NMS will record trace events for this
subsystem to the file in addition to the events that it is
currently recording. This allows you to record tracing
events from several subsystems to a single file.
Default: NMTC
nnnn .PUB.SYS, where nnnn is a number
from 0000 through 9999 and is incremented each time a
new file is created.
ErrorOption The action to be taken if SNA Transport detects an
irrecoverable internal error:
• SUB = Terminate SNA Transport. HP e3000 system
processing continues.
• SYS = System failure. HP e3000 system processing
stops. This allows you to dump the system when an
irrecoverable internal error has occurred.
NOTE Use the SYS option only when requested by your Hewlett-Packard
support contact.
Default: SUB
NumRecords The file size, in units of 128-word records, for link-level
tracing.
Range: 1–32767 (integer)
Default: 1024
Description
SNACONTROL START starts an SNA node. You also can start link-level
tracing (with the
LINKTRACE parameter), and SNA Transport node
tracing (with the
NODETRACE parameter) with this command. Note that
SNA Transport
intrinsic tracing is started with SNACONTROL
TRACEON. Tracing is described in Chapter 5 , “SNA Link
Troubleshooting,” of this manual. You must start the SNA node before
starting any SNA services that use the node.
