Explanation
The operator entered the DISPLAY SMS,TRACE or DISPLAY
SMS,OPTIONS command. This command displays the storage management
subsystem (SMS) trace parameters. When the operator enters the DISPLAY
SMS,OPTIONS command, this message is displayed after message IGD002I,
which displays the other PARMLIB parameters.
In the message
text:
- hh.mm.ss
- The time in hours (00–23), minutes (00–59), and seconds
(00–59). If the time-of-day clock is not working, hh.mm.ss appears
as 00:00:00.
- TRACE {ON|OFF}
- Specifies one of the following trace options for SMS is to use.
The default trace option is ON.
- ON
- Turn on tracing.
- OFF
- Discontinue all tracing.
- SIZE = {nnnnnn[K]|nnnM}
- Specifies the size of the trace table. The default value is 128K.
The default unit is kilobytes. You can specify the size of the trace
table as follows:
- nnnnnn
- The size of the trace table in kilobytes, ranging from 0 to 255000.
This value is rounded up to the nearest 4 KB unit.
- nnnnnnK
- The size of the trace table in kilobytes, ranging from 0K to 255000K.
This value is rounded up to the nearest 4 KB unit.
- nnnM
- The size of the trace table in megabytes, ranging from 0M to 255M.
This value is stored in kilobytes.
- TYPE = {ERROR|ALL}
- Specifies the type of trace entries to be traced. The default
value is ERROR. Descriptions of the TYPE values follow:
- ERROR
- Trace error type of trace entries.
- ALL
- Trace all types of trace entries.
- JOBNAME = {jjj|*}
- Specifies the tracing scope in relation to jobs. The default is *.
Descriptions of the JOBNAME values follow:
- jjj
- Tracing is limited to job jjj.
- *
- Tracing is performed for all jobs.
- ASID = {asid|*}
- Specifies the tracing scope in relation to the address spaces.
The default is *. Descriptions of the ASID values follow:
- asid
- Tracing is limited to asid, which is the name
of an address space.
- *
- Tracing is performed for all address spaces.
The rest of the display indicates which storage
management subsystem events are selected for tracing. If the value
of
stat for an event is
ON, that
event is being traced. If the value is
OFF, that
event is not being traced. The SMS events and their abbreviations
in the message display follow:

- CONFR = stat
- Return data from an active configuration.
- CONFA = stat
- Activate a new configuration.
- ACSPRO = stat
- Perform ACS processing.
- IDAX = stat
- The SMS interpreter and dynamic allocation.
- DISP = stat

- CATG = stat
- SMS catalog services.
- VOLREF = stat
- SMS VOLREF services.
- SCHEDP = stat

- VTOCD = stat
- VTOC and data set services, delete an existing data set.
- VTOCR = stat
- VTOC and data set services, rename an existing data set.
- VTOCC = stat
- VTOC and data set services, create a new data set.
- VTOCA = stat
- VTOC and data set services, add a volume to a data set.
- RCD = stat
- SMS recording services or SMS fast VTOC and VVDS access.
- DCF = stat
- The device control facility.
- DPN = stat
- The device pool select.
- TVR = stat
- A tape volume record update.
- DSTACK = stat
- Data set stacking SSI.
- UAFF = stat
- Unit affinity.
- DEBUG=stat
- Debug service.
- VOLSELMSG = (ON|OFF, nnnn)
- controls the issuance of summarized and detailed volume selection
analysis messages where:
- ON
- turns on the issuance of summarized and detailed analysis messages
for volume selection.
- OFF
- turns off the issuance of summarized and detailed analysis messages
for volume selection. This is the default value.
- nnnn
- is the number of volumes to be included in the detailed analysis
messages. The range of this value is 0–65535. The default is
0 which indicates that no detailed analysis messages will be issued.
- ALL
- indicates that all of the volumes that were used by volume selection
are included in the detailed analysis messages.
Note: When VOLSELMSG(ON,nnnn|ALL)
is specified, where nnnn is greater than zero and
TYPE(ALL) is also specified then one of JOBNAME, ASID, DSNAME, or
STEPNAME must also be specified.
