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.
