NORMAL RUNNING DISPLAY (K DISPLA
Yl
When the transaction subsystem is at a control point, the
console K display indicates:
• Latest transaction sequence number.
• Number of words of unused memory.
• Maximum field length.
• Global task dump limit.
• Subsystem default values for memory dump
arguments.
The K display appears on the system console as shown in
figure 3-5.
The subsystem default values are used to control memory
dumps when explicit arguments are not included in the
CMDUMP or DSDUMP command. Any of these default
arguments can be changed by specifying the corresponding
argument in the K. DSDUMP command.
I
The default values for CMDUMP and DSDUMP are given on
the display. The parameters are:
FW First word address of task memory to be
dumped.
LW Last word address of task memory to be dumped.
EP Exchange package: 0 or 1 (1 indicates that the
exchange package is to be dumped).
OQ
QD
Output queue:
BC Local batch.
EI . Remote batch.
PF Permanent file.
Queue destination:
User number (if OQ=BC).
Equipment identifica'tion (if OQ=EI).
Permanent file name (if OQ=PF).
DB Data base option
If DB=1, all data base file buffers held by
this user are dumped.
If DB=O, no buffers are dumped.
RUN TIME K DISPLAY COMMANDS
When the transaction executive is at its control point, the
following commands can be entered from the system
console or submitted from tasks via the KPOINT request.
Any task can issue the K.DUMP command. Only tasks that
reside on the system task library can issue the other
K display commands. (Refer to the Network Products
Transaction Facility Reference Manual or the TAF/TS
Reference Manual for additional information on the
KPOINT request and the system task library.)
K.ASSIGN,xx.
K. ASSIG N ,xx,db,n.
Assigns a magnetic tape unit to be used for a
journal file. xx is the EST ordinal of the tape
unit. The first form of the command makes unit
xx available for the transaction executive to
assign to the next' tape journal file that
encounters end of reel. Two tape units may be
preassigned. If a tape has not been preassigned in
this manner, an end of reel on a journal file causes
subsequent entries for that file to be placed on
disk.
The second form of the command forces journal
file n (n=1,
2,
or
3)
for data base db, defined as a
tape file, from disk to tape. The transaction
executive copies the data from the disk journal
file to tape xx and places all subsequent entries
for that file on the tape. . This command is
necessary after the transaction executive
initialization to assign tape units to the tape
journal files or after an end of reel on a tape
journal file when no tape had been preassigned to
the transaction executive. All data residing on
the disk for the tape journal file must be able to
fit on the tape assigned by this command or else
the transaction executive unloads the tape and
issues the message *UNABLE TO USE TAPE*.
