Parameter Description for TRACEDEF
- ACTIVE=Yes|No
- Specifies whether (Yes) or not (No) the TRACE facility is started.
The operator can use the $T TRACEDEF, ACTIVE= command to start tracing
if it was initially set off (that is, ACTIVE=No). Note: Do not confuse this parameter with the START=Yes|No parameter specification on the TRACE(n) statement which is used to activate individual (or a range of) trace IDs.
Modification: $T TRACEDEF operator command.
- LOG=(CLASS=,SIZE=,START=)
- Specifies the trace table logging environment.
- CLASS=v|A
- Specifies the output class (A-Z, 0-9) of the trace log data set.
Modification: $T TRACEDEF operator command.
- SIZE=nnnnnnnnnn|500
- Specifies
the maximum size (100-2147483647) (in bytes) that the trace log data
set may attain before it is queued for printing. Note: The proper setting for the this parameter will assure that JES2 will not use all available virtual storage in CSA.
Modification: $T TRACEDEF operator command.
- START=Yes|No
- Specifies whether (Yes) or not (No) the trace log information
is formatted and periodically added to the trace log data set. Yes
further specifies that the trace log data set will be spun off and
printed before it exceeds its maximum size (as specified by the SIZE=
subparameter).
Modification: $T TRACEDEF operator command.
- PAGES=nnnn|9
- Specifies the number (9–1000) of 4K-pages available
to each trace table. The default value is 9. Specifying values 1 through
8 will be increased to 9 automatically. There is a limit of 3000 pages
for maximum trace storage which is the number of tables times the
number of pages per table. This will limit the number of tables to
333 max.
Modification: Single-member warm start.
- TABLES=nnnn|3
- Specifies the number (0-333) of trace tables that
JES2 creates at initialization. Each table is 4K-bytes x PAGES= value
in size. If you specify 1 or 2, the value is automatically increased
to 3. If 0 is specified, the TRACE facility cannot be started or tracing
will be deactivated when the number of tables is reduced to 0. Note: Use this parameter to increase the limit for the JNUM resource that is reported on the HASP050 message.
Modification: $T TRACEDEF operator command.
- TABWARN=nnn|80
- Specifies the percentage (0-100) of trace table use at which the
operator will be alerted through message $HASP050 JES2 RESOURCE SHORTAGE.
If you specify 0, no alert will be given.
Modification: $T TRACEDEF operator command.
