TRACE(n) - Initial tracing value setting
The TRACE initialization statement is used to set the initial values for tracing options. The operator can override these values with the $S and $P TRACE(n) commands.
The TRACE statement can control an individual trace ID (TRACE(n)
), a range of trace IDs (TRACE(n-m) ), or a generic range of trace
IDs (TRACE(n-*) ). If, for example, you specify TRACE(1-*), all defined
trace IDs from 1 through 255 are activated.
Note:
- Individual trace IDs can be started or stopped independent of the overall trace facility by using the START=Yes|No parameter on this statement whether or not the trace facility is active (that is, ACTIVE=Yes or No on TRACEDEF is also specified).
- Trace IDs 1 through 47 are defined for use by JES2.
- If you modify this parameter value and then restart JES2 with a hot start, the parameter value in effect before termination will be used.
