Using the *START,SNARJP command *START,SNARJP

Function

Although the *START,SNARJP command can be issued at any time, the only conditions when it must be used are:
  • If there have been too many attempts to log on with the password incorrectly specified
  • If an *CANCEL,SNARJP,T= command has been issued

In either case, the *START,SNARJP command allows JES3 to accept LOGONs from the specified workstation.

Use SNA RJP Recording Facility to trace SNA RJP processing for a remote workstation. JES3 uses the IATXSNTR macro in SNA RJP modules to create trace entries that you can use to diagnose problems with a SNA RJP workstation. The SNA RJP modules run under the SNARJP DSP that run the remote workstation.

You can invoke the SNA RJP recording facility by including the TRACE=ON parameter on the RJPWS statement that defines the remote workstation. For additional information about the RJPWS initialization statement, see z/OS JES3 Initialization and Tuning Reference.

Traces are printed when:
  • A session is ended
  • The operator enters an *START command with the TRACEOFF parameter
  • Errors are detected when inbound data is decompressed or deblocked
Traces can include:
  • Protocols, including chaining, bracket, and function management header information
  • Negative response sense data
  • Task control block and service request block interactions
  • Results of compare and swap operations
  • Error returns from VTAM®
  • Up to four bytes of pertinent data

Parameters

T=wsname
Specifies the five-character workstation name as specified in the N= parameter of the RJPWS initialization statement.
TRACEON
Activates the SNA RJP trace facility for all sessions on the specified workstation.
TRACEOFF,NOPRT
Indicates that the SNA RJP trace facility should be stopped for all sessions on the specified workstation. A spinoff data set is created for each trace table and is automatically printed. If NOPRT is specified, the trace table is not printed.

See z/OS JES3 Diagnosis for more information about the SNA RJP trace facility.

Example

Allow LOGONs from SNARJP workstation WS001: 
*S,SNARJP,T=WS001
