SEQUENTIAL DISK PROCESSOR (SDP) is a facility which provides access to
disk storage as a sequential medium for storing and retrieving data.
7.1 Include support for SEQUENTIAL DISK PROCESSOR [Y OR N] ? <Y>
JOURNAL provides an on-line trace of all database writes which, when
coupled with the BACKUP utility can provide total database recovery
in the event of a system failure.
7.2 Include support for JOURNAL [Y OR N] ? <N>
Spooling is a facility which allows multiple jobs to simultaneously
7.3 Include support for SPOOLING [Y OR N] ? <N>
INTERJOB COMMUNICATIONS (JOBCOM) allows two DSM-11 jobs to communicate
via assigned JOBCOM channels using MUMPS READ/WRITE commands.
7.4 Include support for INTERJOB COMMUNICATIONS [Y OR N] ? <Y>
Each JOBCOM channel is a pair of pseudo-devices that communicate
via a single RING BUFFER. There are 32 device numbers (224-255)
reserved for a total of 16 channels. Each pair consists of an
even numbered device (the receiver), and the following odd
numbered device (the transmitter).
How many communication channels do you want ? <16>
Each JOBCOM channel requires a RING BUFFER of 2 to 255 bytes.
RING BUFFERS are INPUT/OUTPUT intermediate storage buffers for data being
transferred from one job to another. When the RING BUFFER is filled,
the job transmitting the data must be placed in a wait Q until the
receiving job has removed some of the data. While it may be desireable
to increase communications speed by increasing RING BUFFER size, this
must be traded against memory space considerations.
Enter the default size you would like for JOBCOM ring buffers.
RING BUFFERS will use memory most efficiently if specified in
multiples of 64 bytes.
Enter the size, in bytes, for each RING BUFFER channel ? <64>
LOADABLE DRIVERS provide space for device drivers which may be loaded
or unloaded dynamically while the system is running. It may also
be used for your own special purposes.
TU58, RX02, and BISYNC drivers are all provided as LOADABLE DRIVERS.
If you plan to use these devices, you must select this option.
7.5 Include support for LOADABLE or USER DRIVER SPACE [Y OR N] ? <N>
MAPPED ROUTINES allow you to lock a set of DSM-11 routines into memory
thereby reducing the system overhead required to load a routine into
a user's partition when the routine is called. This can greatly increase
system performance in situations in which application users are sharing
the same routines. However, you must reserve memory space in which to
load these mapped routines.
7.6 Include support for MAPPED ROUTINES [Y OR N] ? <N>
Translation provides a flexible way to logically change the access and
storage of globals.
An entry in the Translation Table specifies where all operations of
a global are to take place (LOCK, READ, SET/KILL). In a simple
translation, all the operations are to the same place. In a complex
translation, the location of each operation is specified, and you
have the ability to specify multiple SET/KILL locations.
7.7 Include support for TRANSLATION TABLE [Y OR N] ? <N>
DSM-11 allows up to seven MOUNTABLE VOLUME SETS to be resident on the
system at any one time. These volume sets are complete and independent
databases. A VOLUME SET may consist of one or more disk packs, and
may have 1 or more UCI's. There is always at least one volume set,
the SYSTEM VOLUME SET (S0) mounted on a DSM-11 system.
7.8 Include support for MOUNTABLE DATABASE VOLUME SETS [Y OR N] ? <Y>
Total System Exec size: 90.53 K Bytes
PART 8: MEMORY BUFFER ALLOCATION
-------
Space remaining for Buffers and Partitions: 3749.44 K Bytes
Each terminal requires two RING BUFFERS of 2 to 255 bytes.
RING BUFFERS are used for INPUT and OUTPUT intermediate storage for
data being transmitted and received. When the RING BUFFER is filled,
the job transmitting the data must be placed in a wait Q until the
the terminal has received some of the data. While it may be desireable
to maximize a job's IO throughput by increasing RING BUFFER size, this
must be traded against memory space considerations.
The default ring buffer size is the size of buffer acquired when a terminal
is first opened. A different buffer size may be selected at open time via
an optionnal OPEN parameter. Memory will be most efficiently used if specified
in multiples of 32 bytes.
RING BUFFER sizes may not be less than 32 bytes or exceed 255 bytes.
8.2 Enter the default terminal RING BUFFER size <128>
RING BUFFER POOL is the memory space from which terminal and JOBCOM RING
BUFFERS are allocated when a device is opened or logged into. Space is
allocated in bytes, and the RING BUFFER pool must hold at least 2
default-sized RING BUFFERS. Your system will require a total of 2 RING
BUFFERs for EACH active terminal and for each active JOBCOM channel.
8.3 Enter the number of bytes to allocate to RING BUFFER space <2176>
Space remaining for Buffers and Partitions: 3747.31 K Bytes
Maximum space that can be used for Buffers: 2047.00 K bytes
DISK-TAPE cache blocks are 1 KB block buffers used for DISK, TAPE, JOURNAL,
VIEW, DMC block mode, TU58, RX02, BISYNC, and all SEQUENTIAL disk operations.
Since disk operations where data is shared for global access is especially
optimized by large disk caches, it is advisable to allocate as much space as
possible for cache buffers. Memory space considerations must be weighed
against the number of cache blocks. Room for three partitions plus space for
a journal overhead (if Journal was selected) must be available. Also, system
constraints require that total buffer allocation space does not exceed the
value shown above.
You must allow for 7 cache blocks plus the number of buffers selected for
Journal.
8.4 Enter the number of DISK-TAPE cache blocks to allocate <2047>
PART 9: SYSTEM DATA STRUCTURES
-------
Space allocated for DISK-MAP and BAD BLOCK TABLE: 33152 Bytes
Space allocated to GLOBAL VECTOR TABLE: 4096 Bytes
Space allocated to SYMBOL TABLE REPACKER: 16384 Bytes
Space allocated to ERROR PACKET SAVE AREA: 1536 Bytes
Space remaining for Data Structures + Partitions: 1646.44 K Bytes
The LOCK TABLE is the system data structure which holds the list
of all data elements that have been locked via the LOCK and
ZALLOCATE commands. A job requesting a LOCK must wait for
space in the LOCK TABLE if the LOCK TABLE is full. Allocation of
of memory to the LOCK TABLE should be made as a tradeoff between
remaining memory space and the number of data elements expected to
be concurrently LOCKED.
9.1 Enter the number of bytes to allocate to the LOCK TABLE <512>
Your system is allowed up to 8 concurrently mounted database volume
sets. Each volume set appears as a single logical database
and may consist of one or more disks. Volume Set 0, (S0) of which
the system disk is the first volume, remains mounted at all times.
Up to 7 additional volumes sets, however, may be mounted and
dismounted as SETS 1 through 3 (S1-S3). You may specify that space
be reserved for one, two or three additional UCI tables. The only
reason for not specifying the maximum is to save memory (1024
bytes/UCI table), at the cost of limiting the number of concurrently
mounted volume sets. Notice that this limitation does not
apply to the mounting of disks for VIEW-only (as is required to
prepare new volumes for backup, etc.), because disks mounted
for VIEW-only are not database structures, and no global or routine
access is allowed to or from those disks.
9.2 Enter the number of ADDITIONAL mountable VOLUME SETS <0>
PART 10: JOB PARTITION DEFINITION
--------
PARTITIONs are allocated in 1024 byte increments.
The following PARTITIONs have been defined:
GARBAGE COLLECTOR system job 1 KB
Job #1 (to guarantee one 10 K byte PARTITION) 10 KB
Space remaining for PARTITION allocation: 1633.00 K bytes
Default-sized PARTITIONs will be used for logins and JOB commands that
do not specify PARTITION size. The size of a partition is expressed
in 1 K Byte increments.
10.1 Enter the default PARTITION SIZE in 1 K Byte increments <16>
PARTITIONS are allocated in 1024 byte increments. The minimum
usable size is 1 K Bytes and the maximum is 16 K Bytes.
Fixed-size partitions may be defined, if desired. However, the system
can automatically allocate space for a new partition from the DYNAMIC
PARTITION POOL whenever a job is started by login or JOB command.
The maximum number of partitions that may be defined in the system is 63.
10.2 Enter fixed PARTITION sizes (in increments) and the number of each.
A <CR> in the size field will terminate the session.
PARTITION size number of each

Space remaining for PARTITION allocation: 1633.00 K bytes
The remainder of memory is assigned to the DYNAMIC PARTITION POOL
PART 11: DATABASE PARAMETERS
--------
WRITE CHECK will cause DSM-11 to read every block it writes to disk
immediately following the write to see if the block was written
correctly and attempt to correct any errors detect. The system will
inform the system manager if there was an error. Selecting this
feature will give you immediate information on the status of disk
writes, however, it does increase disk IO overhead.
11.1 Enable WRITE CHECK after every DISK WRITE [Y OR N] ? <Y>
Configuration KAYS default global characteristics are:
8 Bit Subscripts: Yes
Journaling: No
Collating sequence: Numeric
%-Global protection:

Default global characteristics are applied to all newly created globals
on a configuration-wide basis. While these are the default characteristics,
globals may still be created with different characteristics using
the utility, ^%GLOMAN.
Enter Y if you wish to change the default
Enter N if you wish to leave the defaults unchanged
11.2 Change the DEFAULT GLOBAL CHARACTERISTICS [Y OR N] ? <N>
PART 12: BASIC SYSTEM PARAMETERS
--------
DUAL-PORTING allows two CPUs to dynamically interleave requests to
the same disk. UDA disks that are dual ported require a flag in
memory so that the disk driver knows whether to release control of
a particular unit after its disk transfer has completed. Your answer
should be a series of unit numbers, separated by commas, or the word
"NONE".
12.0 Enter the UDA disk units, separated by commas,
that you wish to be DUAL-PORTED <NONE>
VIEW DEVICE protection restricts the use of device 63
to the SYSTEM MANAGER account and LIBRARY UTILITIES.
12.1a Restrict the use of the VIEW BUFFER [Y OR N] ? <N>
VIEW COMMAND protection restricts the use of the
view command to change memory. With this protection,
only the SYSTEM MANAGER account and LIBRARY UTILITIES
may use the VIEW command to change memory locations.
12.1b Restrict the use of the VIEW COMMAND [Y OR N] ? <N>
The $VIEW function allows users to examine memory locations.
Protecting the $VIEW function restricts its use to
the SYSTEM MANAGER account and LIBRARY UTILITIES.
12.1c Restrict the use of the $VIEW FUNCTION [Y OR N] ? <N>
The JOB command allows users to start jobs, including jobs
in different UCIs and volume sets than the originating one.
Protecting this capability means that only the SYSTEM MANAGER
account and LIBRARY UTILITIES may start a job in UCIs other
than the originating UCI.
12.1d Restrict the use of the JOB COMMAND to start jobs
in different UCIs and VOLUME SETS [Y OR N] ? <N>
ZUSE PROTECTION will allow the use of the ZUSE command only from
the SYSTEM MANAGER account and LIBRARY UTILITIES with names that
begin with the % character.
12.2 Restrict the use of the ZUSE command [Y OR N] ? <N>
LOGIN SEQUENCE ECHO will cause all characters typed during login
to be echoed on the terminal.
12.3 Echo the LOGIN SEQUENCE [Y OR N] ? <Y>
The APPLICATION INTERRUPT key, when enabled, will cause an <INRPT>
error to occur. The error may then be trapped with an error processor
and handled as a special event.
When a terminal device is first OPENED it is given the system-wide
default APPLICATION INTERRUPT key. An OPEN command parameter allows
you to define 1 or more INTERRUPT keys for that specific terminal.
The APPLICATION INTERRUPT key may also be used to LOG in to a
non-AUTOBAUDED terminal. The RETURN key may be used to LOG
in to any terminal.
The key must be a control character with a decimal value between
0 and 31.
12.4 Enter the ASCII DECIMAL value
of the default APPLICATION INTERRUPT KEY <3>
The PROGRAMMER ABORT key is available only to programmers logged
into DSM-11 in DIRECT mode. When pressed, the key will cause
an <ABORT> error to occur. Any error processing routines will
be bypassed and the execution of any application code will be
terminated.
The key must be a control character with a decimal value between
0 and 31.
12.5 Enter the ASCII DECIMAL value
of the default PROGRAMMER ABORT KEY <8>
DSM-11 will restart automatically when power is restored
following a power outage, if memory is still intact. If the power
outage is more than momentary, however, main memory will be
erased unless it is either core or supported by batteries.
Often, however, machines without either of these features can
recover because the outage did not destroy memory. The time
delay is necessary to allow disk drives to become ready. If you
wish to restart under operator control, set the time to 0.
Otherwise enter a time interval up to 500 seconds.
Note that if power-fail restart occurs while magtape journaling
is in progress, operator intervention will be demanded.
12.6 Enter the number of seconds to delay
SYSTEM RESTART after a POWER FAILURE <40>
The TELEPHONE DISCONNECT DELAY allows a time delay between logout
and telephone line disconnect. This is very useful in dial-up
environments where it is necessary to log out of one UCI and into
another. If the DELAY is set to 0, DSM-11 will disconnect the
telephone line immediately following logout. The maximum allowed
value is 250 seconds.
12.7 Enter the number of seconds to delay TELEPHONE
DISCONNECT after LOGGING OUT of a MODEM CONTROLLED LINE <15>
The number of significant digits returned from a division operation
will affect both accuracy and speed of computation
Increasing the number of significant digits will increase the degree
of accuracy, but will also require more processor time.
DSM-11 supports computations which yield between 10 and 31 significant
digits.
12.8 Enter the number of
SIGNIFICANT DIGITS to include in DIVISION computations <12>
The FREQUENCY of the computer's POWER SOURCE is either 50 HZ or 60 HZ
The information about frequency is used by DSM-11 to accurately keep
the time.
12.9 Is the LINE FREQUENCY 60 HZ [Y OR N] ? <N>
Enter the 3-character password that will let users enter Programmer Mode.
Use of control characters (ASCII value < 32), while allowable, could,
