Parameters
- AUTOCMD
- Specifies
the number (2-9999) of automatic commands that can be active concurrently
in JES2. The value should be large enough to permit operators to leave
a JES2 dynamic display in each user defined ("out of line") area
of all MCS consoles.
- BUFFREE
- Display
the current number of free console message buffers in private storage.
- BUFNUM
- Displays
the number of console message buffers to be provided for JES2 from
private storage (above 16-megabytes in virtual storage). The value
displayed for BUFNUM has been rounded up to the next page boundary
to take advantage of available storage.
- BUFWARN
- Displays
the percentage of console message buffers used at which the $HASP050
message alerts the operator of a shortage of console message buffers.
- CMDNUM
- Displays
the maximum number of console message buffers to be allocated from
common storage for JES2 command processing.
- CONCHAR
- A
single character used to identify JES2 commands from MCS consoles.
One of the following characters will be displayed:
| % : ¢ + ¬ # [ ] ! &
- @ . $ / ? = _ ( * "
- DISPLEN
- Displays
the length that is used for the displays and error message processing
of:
- All initialization statements
- Those commands processed by $SCAN (most of those commands are
the $D and $T commands for initialization statement parameters)
- The $DU command.
- DISPMAX
- Displays
the maximum number of lines that JES2 displays for those requests
processed by the $SCAN facility. Those requests include initialization
parameters and the $T and $D commands for initialization parameters.
- MASMSG
- Displays
the maximum number of messages or commands that can be queued between
any two members of a multi-access spool configuration.
- RDIRAREA
- Displays
the default console out-of-line area which JES2 uses to direct display
responses for commands subject to redirection. All redirectable commands
which do not use either an L= or do not have redirection set up on
the issuing console for that command have their responses directed
to the RDIRAREA specification.
- RDRCHAR
- Displays
the character used to identify all JES2 operator commands entered
from a local or remote card reader.
One of the following characters
will be displayed:
| % : ¢ + ¬ # [ ] ! &
- @ . $ / ? = _ ( ) * "
- SCOPE
- Specifies whether the command prefix specified on the CONCHAR
parameter is recognized by this MVS™ system
only, or by all MVS systems in the sysplex.
SCOPE=SYSTEM
specifies that the prefix is recognized by this MVS system,
but if the command was entered on a different MVS system,
that system would not recognize or send the command to this system.
SCOPE=SYSPLEX
specifies that the prefix is recognized as belonging to this system
no matter which MVS system in the sysplex the command was entered
on, and, if necessary, is routed to the correct MVS system
for processing by this subsystem.
Authority Required
This command requires display authority.
The description of the $T RDRnn command explains how to ensure that
the authority of the appropriate MVS system
command group is assigned.
This command requires control security
access authority. For a description of assigning command input authority,
see z/OS JES2 Initialization and Tuning Guide, SA32-0991.
Scope
Single member. The response
to this command will be a display of information about this member
only. You might want to use this command to get information about
all members in the MAS. To do so, you can use the MVS ROUTE
*ALL command to issue this command to all active members (if the JES2
command character is the same on all members). See z/OS MVS System Commands, SA38-0666 for
more information on using the ROUTE *ALL command.
Messages
The $HASP830 message displays
the current values of all the parameters on the CONDEF statement.
Example
1 $d condef
$HASP830 CONDEF AUTOCMD=20,CONCHAR=$,BUFNUM=10013,CMDNUM=100,
$HASP830 BUFFREE=10013,BUFWARN=80,MASMSG=200,RDIRAREA=Z,
$HASP830 RDRCHAR=$,SCOPE=SYSTEM,DISPLEN=64,DISPMAX=100
JES2
displays all the console communication characteristics. Note that
the value displayed for BUFNUM has been rounded up to the next page
boundary to take advantage of available storage.
