Considerations The RJECIS command starts the Exchange/SNA command interpreter and is an
implied TACL RUN command. For complete information on the TACL RUN
command, see the TACL Reference Manual.
The Exchange/SNA command interpreter cannot be run as a NonStop process pair.
All the RUN command options that relate to NonStop process pairs and backup
processes do not apply to the RJECIS command.
Limits to Number of Supported Subdevices
The total number of subdevices supported by a line server, including the console
subdevice, should not exceed the number of LUs available for the line server to use.
The maximum configuration, then, is six LUs and six subdevices (including the
console subdevice if any).
If you set up the line server so that it supports more subdevices than the number of
subdevices, the following problem occurs. If all LUs are in use for nonconsole data
streams and you request that console data be sent to the host, one of the data streams
is suspended to make an LU available for the console data. The suspended data
stream remains suspended indefinitely; Exchange/SNA does not resume transmission
of the suspended data stream.
Examples 1. This example shows the simplest form of the RJECIS command:
> RJECIS
2. This example starts the Exchange/SNA command interpreter, which then reads
and executes the commands in a file called J031A. When the end of J031A is
reached, the Exchange/SNA command interpreter stops and control is returned to
the command interpreter:
> RJECIS /IN J031A/
3. This example starts the Exchange/SNA command interpreter and specifies that
the first CONNECT command start a named line server on a remote system called
\PHAR. The line server is created from the program file
$SYSTEM.SYSTEM.SNAXSV and uses a data communications line on \PHAR
called $SNA1:
> RJECIS PROGRAM \PHAR.$SYSTEM.SYSTEM.SNAXSV, &
NAME \PHAR.$SNA1, LINE \PHAR.$SNA1, &
LOGON \PHAR.DATA1.HOST1.LOGON, &
HOST JES2
4. This example assumes that an Exchange/SNA line server called $SNA3 exists.
The RJECIS command starts the Exchange/SNA command interpreter and
specifies that the first CONNECT command connect to the existing line server,
$SNA3:
> RJECIS NAME $SNA3
