$D NJEDEF - Display the JES2 Network Environment
Function
To display current specifications for the JES2 network environment.
Syntax
Parameters
- CONNECT
- Specifies that NJE connections for APPLs, LINEs, or SOCKETs that specify or defer to CONNECT=YES will automatically be initiated or restarted. The interval displayed is the time (in minutes) between attempted connections.
- DELAY
- Displays the maximum length of time, in seconds (10-999), that a message or command is delayed in any stage of transmission between nodes before the system assumes that possible lockout situations have occurred.
- HDRBUF=[FREE|LIMIT|WARN]
- Allows
installations to display the amount of storage used by NJE headers
and trailers.
- FREE
- Displays the number of header/trailer cells at an installation.
- LIMIT
- Displays the maximum number (10-9999) of NJE header and trailer cells allocated at this installation for jobs and SYSOUT data received from the network.
- WARN
- Displays the percentage (0-100) of NJE header and trailer cells in use at an installation.
- JRNUM
- Displays the number (0-7) of network job receivers associated with each line.
- JTNUM
- Displays the number (0-7) of network job transmitters associated with each line.
- LINENUM
- Displays the number of lines (0-65535), including CTC (channel to channel) adapters, to be used by this JES2 member for NJE communications.
- MAILMSG
- Displays whether (YES) or not (NO) JES2 issues the $HASP549 mail notification message automatically to notify a userid that a transmitted file has arrived from another node or a spool reload procedure.
- MAXHOP
- Displays the maximum number of nodes (0-32k) a job or output can cross to reach a destination.
- NODENUM
- Displays the maximum number (1-32767) of nodes in the NJE network to which this system belongs, or a value greater than or equal to the highest numbered node in your system.
- OWNNAME
- Displays the name of this node.
- OWNNODE
- Displays the number (1-32767) of this node.
- PATH
- Displays the maximum number (1-8) of paths from the local member to a given non-adjacent node that must be maintained simultaneously.
- RESTMAX
- Displays the maximum tolerable resistance (0 to 79992000) of a network connection for both adjacent and non-adjacent nodes.
- RESTNODE
- Displays the resistance (1-2000) of this node to the flow of jobs through the network.
- RESTTOL
- Displays the maximum difference in resistance (0-8000) allowed between the best possible path and an acceptable alternate path.
- SRNUM
- Displays the number (0-7) of NJE SYSOUT receivers associated with each NJE line. This value should match the STNUM specification at other subsystems with which this member communicates directly.
- STNUM
- Displays the number (0-7) of NJE SYSOUT transmitters associated with each NJE line.
- TIMEtol
- Displays the time variation in minutes (0-1500) that occurs between the time-of-day (TOD) clocks of this node and any adjacent node at signon.
- PRECHECK=YES|NO
- Displays whether NJE jobs that are marked dubious (because of the VFYPATH or VERIFY_SUBNET specification) must pass additional verification processing before being allowed to run on the local node. The pre-check ensures that the job can pass verification without any submitter information being passed to the security product.
- VERIFY_SUBNET=YES|NO
- Displays whether subnet path verification is done for jobs and commands arriving by way of NJE. This setting has no effect if the local node is not within a subnet (NODE(xx) SUBNET= is blank for the local node) and for jobs and commands that indicate they are from a node that is not in the local subnet.
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. The $T NODE(nnnn) command sets the command authority for a node.
This command requires control security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide.
Scope
Single Member. The response to this command will be a display of information about this member only.
Messages
The $HASP831 message displays the current values of all the parameters on the NJEDEF initialization statement.
Examples
1 $D njedef
$HASP831 NJEDEF OWNNAME=POK,OWNNODE=1,DELAY=120,
