nonaudited file
nonaudited file. A disk file that is not flagged for protection by TMF. TMF does not control
where a nonaudited file resides, so the file can exist on an audited volume or any other
volume.
NonStop SQL. A relational database management system that provides efficient online
access to large distributed databases. The main components of NonStop SQL are a
data dictionary; the SQL language for definition, manipulation, and control of data; a
programmatic interface; a conversational interface; a report writer; and a set of utilities.
NonStop Transaction Services/MP (TS/MP). A product that provides process
management and link management functions for OLTP applications on NonStop
systems. NonStop TS/MP consists of the PATHMON process, the LINKMON process,
the PATHCOM process and interface, and the Pathsend procedures. Together with
TMF, NonStop TS/MP forms the foundation for the HP open transaction processing
services, including those provided by the RSC and POET products, and the NonStop
TUXEDO system. See also Pathway/TS.
O
OBEY command file. A file that serves as a source for command input. Command files are
prepared using a standard text editor. When such an input file is invoked, TMFCOM
reads and executes each command in the file sequentially: this can be done either
through the OBEY command or by specifying the command file as the input file when
you run TMFCOM.
offline backup. A static copy of a database file (audited or not audited) written to secondary
storage media (such as tape) while the database is inactive (TMF may be running, but
no transactions are being processed). You can use an offline backup to recover a
database to the time that the backup was made, but you cannot recover the database
to the current time. Contrast with online backup.
OLTP. See online transaction processing
.
OLTP application. An application in which many users can update data simultaneously,
recording the changes in the database as they are entered.
online backup. A copy of an audited database file written to secondary storage media
(such as tape) while transactions are being processed by database applications and
TMF is running. If the database is damaged and the audit trail files have been regularly
backed up, the file recovery process can restore the online backup files to disk and
then apply the audit trail images to reconstruct the files. Contrast with offline backup
and audit dump.
online dump. A copy of an audited database file written to tape or disk when a DUMP
FILES command is issued. If the database is damaged, the file recovery process can
restore the online dump files to disk and then apply the audit trail images to reconstruct
the files. Online dumps can be made while transactions are being processed by
database applications; that is, while TMF is running.
