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,
  $HASP831         HDRBUF=(LIMIT=10,WARN=80,FREE=10),JRNUM=1,
  $HASP831         JTNUM=3,SRNUM=4,STNUM=3,LINENUM=3,MAILMSG=NO,
  $HASP831         MAXHOP=0,NODENUM=5,PATH=1,RESTMAX=79992000,
  $HASP831         RESTNODE=100,RESTTOL=0,TIMETOL=1440

The $HASP831 message displays the current status of global network definitions in the installation.
