Remote execution server parameters

The system parameters required by the Remote Execution server are passed by the PARM operand of the EXEC statement in the Remote Execution cataloged procedure. Update the following parameters as required by your installation:
EX= or EXIT=
Name of a user exit routine to inspect and alter JOB and EXEC parameters prior to submission of TSO batch jobs initiated by remote commands.
IPV6=
Y or N, indicating whether the server should attempt communication over an IPv6 network. If this option is not specified, the server attempts IPv6 communication. Specifying N for this option prevents IPv6-only clients from communicating with this server.

Tip: This option is useful for installations that have not migrated user exits to accommodate IPv6 addresses.

PRE= or PREFIX=
A four-character value used as the first four characters in the job name of jobs that are submitted. The remaining characters of the job name is a sequential number in the range of 1 - 9999.
PUR= or PURGE=
Y or N, indicating whether a job submitted by the server should be purged immediately after execution or held in the output queue.
TSO= or TSOPROC=
The name of the TSO batch procedure. The default is IKJACCNT. The name IKJACCNT can be modified in the exit routine specified with the EXIT parameter.
MSG= or MSGCLASS=
The MSGCLASS parameter for TSO batch jobs submitted to execute remote commands. The default is H, which points to a HELD output class.
Restrictions:
  • This parameter must not be altered by the exit routine.
  • For JES3 users, the HELD output class needs to be defined as a HELD output class for external writer.
TSC= or TSCLASS=
The SYSOUT class for the SYSTSPRT DD statement for submitted jobs. The default is A.

Restriction: For JES3 users, the HELD output class needs to be defined as a HELD output class for external writer.

MAX= or MAXCONN=
The maximum number of open sockets at any one time. Usually, each client requires 2 sockets while the command is being processed and the output is being returned. The minimum acceptable value is 512. This is also the default.
TR= or TRACE=
The trace options that are to be in effect for the Remote Execution server.

Rule: If more than one trace parameter is specified, enclose the parameters in parentheses.

LOG
Specifies trace records written to SYSPRINT.
NOL= or NOLOG
Specifies no trace records written to SYSPRINT.
SEN= or SEND
Specifies trace records sent to the client.
NOS= or NOSEND
Specifies no trace records sent to the client.
CLI= or CLIENT=client
Specifies a specific client host for which trace records are to be produced.
ALLC= or ALLCLIENTS
Specifies that trace records are to be produced for all clients.
RE= or RESET
Sets the trace options to NOLOG, NOSEND, ALLCLIENTS.
SL= or SECLABEL=
Y or N, indicating whether the server should attempt to add a security label to the job card. If this option is not specified, the server attempts to add a security label to the job card. If Y is specified for this option, the server adds a security label (if one exists) to the job card following the message class parameter. For more information about the multilevel security environment and configuring z/OS® Communications Server in that environment, see the multilevel security information in the z/OS Communications Server: IP Configuration Guide.
Use the MODIFY command to dynamically change all but the following parameters:
  • MAXCONN
  • PREFIX
  • IPv6
  • SECLABEL

Tip: All parameters can now be abbreviated. For example, EXIT can be abbreviated to EX.
