|
Starts an SNA node, link-level tracing, and SNA Transport node tracing.
SNACONTROL START can be issued from a session, a job, a program, or in break. Pressing [BREAK] has no effect on this command.
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 of this manual. You must start the SNA node before starting any SNA services that use the node. If you are using a manual-dial modem, you can begin to dial after this logging message is displayed on the console: Node NodeName ready for activation by host Note that if you are using a manual-dial modem, console logging for SNA Transport logging class CLAS0013 must be enabled (see chapter 3), so that the above message can be displayed. Also, note that once a node is active, reissuing this command for that node causes an error. For example, if node IBMNODE is already active, and you try to start node tracing for that node by typing SNACONTROL START;NODE=IBMNODE;NODETRACE you will get an error message. SNACONTROL START;NODE=IBMNODE;LINKTRACE;ERROPT=SUB The node IBMNODE is to be started. Also, partial (the default) link-level tracing is to be started, and the trace data is to be written to the default trace file (as explained earlier, it will automatically be written to the SYS account). If SNA Transport finds an irrecoverable internal error, SNA Transport is to be terminated, but HP 3000 processing is to continue. (Note that if the ERROPT parameter was not specified, the same action would be taken for an irrecoverable internal error, because ERROPT=SUB is the default.) SNACONTROL START;LINKTRACE=FULL,TF01;NODETRACE The only configured node is to be started. Also, full link-level tracing (written to the file TF01 in the SYS account [as explained earlier]), and node tracing (written to the default file) are to be started. Note that if more than one node was configured, 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 START;LINKTRACE=,TF01 The only configured node is to be started. Also, partial (the default) link-level tracing is to be started, and the trace data is to be written to the file TF01 in the SYS account (as explained earlier). Note that if more than one node was configured, 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 START;LINKTRACE=;NODETRACE 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. |
