Parameters

z/OS JES3 Initialization and Tuning Reference
SA32-1005-00

NAME=name
Specifies a 1-8 character name that uniquely identifies this Netserv and is also used to start the Netserv address space. The name must contain only A-Z, @, $, #, or 0-9 and cannot start with a digit.
HOSTNAME=hostname
Specifies the IP host name or IP address that the Netserv will use to listen over TCP/IP for incoming data. This name can be omitted to use the default, which tells TCP/IP to listen over any IP address that is defined for this processor. Multiple Netservs can listen over the same host name or use the default, if different ports are used.

The host name can consist of up to 60 characters and must be a legal TCP/IP address or host name defined to the TCP/IP resolver. The host name can be in IPV4 or IPV6 format.

PORT=
Specifies a port number that the Netserv will use, in combination with the host name, to listen over TCP/IP for incoming data. The port must be a number from 0 to 65,535. Port 0 indicates that when the Netserv starts a standard service name of VMNET, VMNET will be used instead of a numeric port. The service of VMNET corresponds to port 175. Although there is a corresponding port for the service NJENET-SSL, it is suggested that you use the TLS=YES parameter on the NJERMT statement or *MODIFY,NJE command instead.
SYSTEM=
Specifies the name of the system that the Netserv will run on. If the SYSTEM= parameter is omitted, the Netserv will run on the global. After a DSI, an active Netserv that defaulted to the global will remain running on the old global. However, the Netserv will run on the new global if it is subsequently brought down and back up.
STACK=
Specifies the name of the stack that TCP/IP uses to get its definitions when the Common INET (CINET) configuration is being used. If the STACK=name parameter is omitted, TCP/IP will use all stacks. The stack must contain only A-Z, @, $, #, or 0-9 and cannot start with a digit. When only an INET configuration is being used, any specification of a stack name is ignored.
ITRACE=
Indicates that internal tracing in the Netserv address space will be active.
JTRACE=
Indicates that JES tracing will be active. JES tracing occurs during JES specific exit points in the Netserv when data records, headers, and trailers are transmitted and received.
VTRACE=
Indicates that verbose tracing will be active. Verbose tracing involves various diagnostic messages being written to the console and job log from the Netserv address space.
