Syntax
SNACONTROL TRACEON;NODE=NodeName
[;LINKTRACE[=[TraceType][,TraceFile]]]
[;INTRINSIC=LUName[,TraceFile]]
[;NODETRACE[=TraceFile]]
[;TFILESIZE=NumRecords]
Use
SNACONTROL TRACEON can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command.
Parameters
- NodeName
Conditionally required. The name of the active SNA node for which you want to turn tracing on. The name can be up to eight alphanumeric characters long; the first character must be alphabetic.
If only one SNA node is active, this parameter is optional: If you do not include it, the specified tracing for the active node is turned on. If more than one node is active, this parameter is required: If you do not include it, an error message is displayed and no tracing is started.
- TraceType
The kind of link-level tracing to be started:
FULL = Full line tracing: All of the bytes of each link frame are traced.
PARTIAL = Partial line tracing: Only the first 16 bytes of each link frame are traced.
- TraceFile
The name of the disk file that is to contain the trace data. This must be a valid MPE file name or fully qualified MPE file reference. Standard MPE file naming conventions apply.
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: NMTCnnnn.PUB.SYS, where nnnn is a number from 0000 through 9999 and is incremented each time a new file is created.
- LUName
Required. The name of the LU for which SNA Transport intrinsic tracing is to be turned on. The name can be up to eight alphanumeric characters long; the first character must be alphabetic.
NOTE: Activate SNA Transport intrinsic tracing with this command only when recommended by your Hewlett-Packard support contact.- NumRecords
The file size, in units of 128-word records, for link-level tracing.
Range: 1-32767 (integer)
Default: 1024
Description
SNACONTROL TRACEON turns on link-level tracing (with the LINKTRACE parameter), SNA Transport intrinsic tracing (with the INTRINSIC parameter), and SNA Transport node tracing (with the NODETRACE parameter). Note that SNA Transport node tracing is also turned on with SNACONTROL START. Tracing is described in Chapter 5 "SNA Link Troubleshooting" of this manual. You can use intrinsic tracing to verify SNA Transport procedure calls. For an SDLC link, you can use link-level tracing to verify data passed between SNA and the SDLC link driver and between the link driver and the PSI card.
Examples
SNACONTROL TRACEON;NODE=IBMNODE;LINKTRACE Partial (the default) link-level tracing is to be started for all LUs on node IBMNODE. The trace data is to be written to the default trace file. SNACONTROL TRACEON;LINKTRACE=FULL,TF01;INTRINSIC=LU02 Full link-level tracing is to be started for the only active SNA node, and the trace data is to be written to file TF01. Also, intrinsic tracing is to be started for LU02 on the node and that trace data is to be written to the default trace file. Note that if more than one node was active, this command would not be valid: A list of configured nodes would be displayed, and the command would have to be reissued with the proper NODE=NodeName parameter included. SNACONTROL TRACEON;LINKTRACE=,TF01 Partial (the default) link-level tracing is to be started for the only active SNA node, and the trace data is to be written to the file TF01. Note that if more than one node was active, this command would not be valid: A list of configured nodes would be displayed, and the command would have to be reissued with the proper NODE=NodeName parameter included. SNACONTROL TRACEON;LINKTRACE=;INTRINSIC=LU02 This command is not valid because the equal sign is specified with the LINKTRACE parameter, but no values are specified after it (the equal sign should be included only if one or both of the values after it are specified); an error would occur.
