Enables or disables the STREAMS device; it permits users to submit job/data streams or prevents them from doing so.
STREAMS {ldev} {OFF }
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.
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.
To enable jobs and data streams on logical device number 10, enter STREAMS 10 To disable data streams, enter STREAMS OFF
