STREAMS
Enables or disables the STREAMS device. Allows or disallows users to
submit job/data streams.
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 Notes
The operator executes this command after a startup to enable the STREAM
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 processes 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)
The device normally configured as the STREAMS device is LDEV 10.
However, LDEV 10 may not correspond to an actual device, such as a tape
drive, 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.
Use
This command may be issued from a session, job, program, or in BREAK.
Pressing Break has no effect on this command. It may be issued only from
the console unless distributed to users with the ALLOW command.
Examples
To enable jobs and data streams on logical device number 10, enter:
STREAMS 10
To disable data streams, enter:
STREAMS OFF
