number 24, BATCHIO should be assigned to
control point 22. This command is not valid if a
job currently assigned to control point n has a
queue priority greater than MXPS. BATCHIO
must be active in order to use any of the local
batch peripheral devices. Activity at the
BATCHIO control point can be monitored on the I
display (refer to section 4).
Response to line printer errors is controlled by
setting sense switch 1 as follows:
Entry Response
n. ONSW1. Lines causing print error
messages are not flagged or
retried.
n. MAGNET.
n Control point number
for BATCHIO.
Calls the magnetic tape subsystem to control
point n. This should be the third from last control
point. For example, if the system (last) control
point is number 24, MAGNET should be assigned
to control point 21. This com mand is not valid if
a job currently assigned to control point n has a
queue priority greater than MXPS. MAGNET (the
magnetic tape executive) must be active in order
for tape processing and resource allocation to
take place and to make the resource mounting
preview (E,P.) available. Tape use' can be
monitored on the tape status and preview displays
(refer to description of E display in section 4).
n. MCSffff. t
I
NOTE
I
Unit numbers on tape units
must not be changed after
MAGNET is initialized. Also,
MAGNET should not be stopped
(via the STOP command) while
tapes are assigned.
Calls the message control system (MCS) to control
point n. This command is not valid if a job
currently assigned to control point n has a queue
priority greater than MXPS. MCSffff.t calls a
procedure file named MCSffff under the system
user index, which initiates the MCS subsystem.
n.MSSffff. t
Calls the mass storage subsystem processing
program to control point n. This command is not
valid if a job currently assigned to control point n
has a queue priority greater than MXPS. The
MSSffff command calls a procedure file named
MSSffff, under the system user index 3777778,
which initiates the mass storage subsystem (MSS).
n.NAMffff.t
Calls the network access method (NAM) to control
point n. This command is not valid if a job
currently assigned to control point n has a queue
priority greater than MXPS. NAMffff. t calls a
procedure file named NAMffff under the system
user index, which initiates several NAM supervisor
modules. These modules appear momentarily at
different control points as needed during N AM
activity.
Additional commands which you can enter during
N AM initialization are described in section 7.
n. RBFffff.t
Calls the remote batch facility (RBF) to control
point n. This com mand is not valid if a job'
currently assigned to control point n has a queue
priority greater than MXPS. RBFffff. t calls a
procedure file named RBFffff under the system
user index to initialize RBF. NAM must be active
at a control point to use RBF.
IAFffff.t
Calls the interactive facility (network
tim~sharing
subsystem) to control point 1. This
command is not valid if a job running at control
point 1 has a queue priority greater than MXPS.
A time-sharing subsystem (either IAF or TELEX)
must be active before jobs can be entered from a
tim~sharing terminal. Only one tim~sharing
subsystem can be active at a time. Use the T
display (refer to section 4) to monitor activity at
the tim~sharing subsystem control point.
Ensure that NAM is active at a control point
(refer to the B display) before you enter the
IAFffff com mand.
Several options are available to control the
operation of IAF. Select these options by setting
sense switches after the subsystem is activated.
Although normal operation does not require these
sense swi tches to be set, sense swi tch 5
(l.ONSW5.) is set by default when the
tim~sharing subsystem is activated. Once set,
the sense switches may be turned off again by
entering 1.0FFSWx. (x is the sense switch
number.)
Entry
1.0NSW1.
1.0NSW2.
Response
When the tim~sharing subsystem
is terminated (by 1.STOP
command), enter users into
recover state and inhibit
restarting operations.
Enable the tim~sharing
subsystem to use the delay queue
feature. This allows response
time to appear more consistent to
users by delaying response in a
lightly loaded system. Analysts
can set this parameter by altering
assembly constants wi thin IAF.
tThe characters ffff are optional; if required, installation personnel must supply the one to four alphanumeric characters to
be used.
