structured query language conversational interface
(SQLCI)
structured query language conversational interface (SQLCI). A line-oriented terminal
interface that enables a user to enter SQL commands, format and run reports, and
operate database utilities.
structured query language (SQL) object program. The object file containing the set of
executable machine language instructions produced from a host language source
program with embedded SQL statements.
Subsystem Programmatic Interface (SPI). A common, message-based interface that can
be used to build and decode messages used for communication between requesters
and servers (such as in a management application). It includes procedures to build and
decode specially formatted messages; definition files in C, TAL, COBOL, and TACL for
inclusion in programs, macros, and routines using the interface procedures; and
definition files in DDL for programmers writing their own subsystems.
subvolume. A part of a fully qualified file name. A subvolume is a named logical area on a
disk where users can store files that are usually related to one another. Any user can
create a subvolume by creating a file and naming the new subvolume as part of the file
specifier. A subvolume ceases to exist when the last file in the subvolume is purged. A
subvolume name consists of one to eight alphanumeric characters, the first of which
must be alphabetic.
super ID. A privileged user who can read, write, execute, and purge all files on the system.
The super ID is usually a member of a system-supervisor group. The super ID has the
user ID 255,255.
timestamp. An identifier that indicates when a file was created or modified.
HP NonStop Transaction Management Facility (TMF). A product that provides
transaction protection and database consistency in demanding online transaction
processing (OLTP) and decision-support environments. It gives full protection to
transactions that access distributed SQL and Enscribe databases, as well as recovery
capabilities for transactions, online disk volumes, and entire databases. To furnish this
service, TMF manages database transactions, keeps track of database activity through
audit trails, and provides database recovery methods.
unstructured file. An Enscribe file type on a NonStop system that is essentially a byte
array on disk that starts at byte address 0 and continues sequentially upward through
whatever byte address is identified by the end of file (EOF).
VDP. Abbreviation for virtual disk process.
virtual disk process (VDP). The SMF process that implements location-independent
naming. This is a process pair that is treated like a physical disk process from an
application viewpoint. Also known as virtual volume process.
virtual volume. A process name used instead of a physical volume name to provide
location-independent naming.
