Learn About Server Traces

Data from server traces is stored in the EMS log in message 21034 (

“See the Trace Event Message

Format” (page 56)

).

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

Once 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
