4.3.2 Diagnosing Problems with the MVSSERV Command

 






   MVSSERV supplies diagnostic information that can be put into a TSO/E trace 
   data set. Your system programmer must first allocate this trace data set 
   and give you its name. 



   By specifying the TRACE or IOTRACE parameters on the MVSSERV command, you 
   can indicate whether you want some or all diagnostic information in the 
   trace data set. If you specify the TRACE parameter, the trace data set 
   includes informational and error messages, an execution path table that 
   tracks module calls, and the requests and replies sent between the PC and 
   the host. If you specify the IOTRACE parameter, the trace data set 
   includes all TRACE output plus I/O related information such as 
   transmission data and the structured fields associated with the data. If 
   you do not specify a parameter, the default is NOTRACE and you get no 
   diagnostic information.
