Starting and stopping server traces

Data from server traces is stored in the EMS log. The event ID is 21034.

The tracing facility generates a pair of messages for each function that is traced:

  • First message — Contains the input parameters to the function

  • Second message — Contains the output from the function

After a trace is enabled for a data source, all servers that can write to the EMS alternate collector begin writing the input and the output data for each function executed during the trace period. The following data is collected for each function:

  • Session ID

  • Component name

  • Object reference

  • Sequence number

  • Input values to the function or output from the function
