STREAMS

STREAMS

     Enables or disables the STREAMS device; it permits users to
     submit job/data streams or prevents them from doing so.  (CM)

SYNTAX

     STREAMS {ldev}
             {OFF }

PARAMETERS

ldev                The logical device number of the STREAMS device.
                    This device must also have an output device number
                    or class that references logical devices of type 32.
                    Any input device, except the system console or
                    terminals, may be used, providing that it was
                    configured as job-accepting in the SYSGEN dialog.

OFF                 Disables the STREAMS facility.

OPERATION

     The operator executes this command after a startup to enable
     the STREAMS facility.  The STREAMS device must be enabled
     each time the system is brought back online in order to
     allow users to stream jobs.  (Streamed jobs are processed
     separately by MPE/iX, allowing users to continue with other
     work at their terminal.  If the streamed job is submitted on
     a tape drive rather than from a terminal, MPE/iX will
     process it without requiring the user's attention.)  Any
     attempt to stream a job when the STREAMS facility is
     disabled generates the following message

     STREAM FACILITY NOT ENABLED SEE OPERATOR.  (CIERR 82)

     However, ldev 10 may not correspond to an actual device,
     such as a tape drive or card reader, physically connected to
     the computer.  If this is the case, then the STREAMS device
     is considered a "pseudo-device".  Regardless of whether the
     device physically exists or not, it must be entered into the
     I/O Configuration Table as a legitimate logical device.  It
     must be assigned the device class JOBTAPE.

     This command may be issued from a session, job, in BREAK, or
     from a program.  Pressing [Break] has no effect on this
     command.  It may be issued only from the console, unless it is
     distributed to users with the ALLOW command.

EXAMPLE(S)

     To enable jobs and data streams on logical device number 10, enter

     STREAMS 10

     To disable data streams, enter

     STREAMS OFF
