Commands STREAM thru XEQ
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
