configuration management.
configuration management. The process of configuring the production system hardware and
software to adapt to changes. One of the operations disciplines in the operations
management model. See operations management model.
CONFLIST. A listing that contains all SYSGEN or SYSGENR commands and responses,
including error and warning messages, that occur during processing of the configuration
files and building of the new operating system. As SYSGEN or SYSGENR processes
each line of the CONFTEXT input file, it writes actions taken to the CONFLIST output
file. It then creates maps describing how it builds the new operating-system image.
These maps are useful for debugging purposes.
CONFTEXT file. The main configuration file, copied by SYSGEN or SYSGENR from the
input configuration file (CONF
nn), that contains all of the hardware and software
descriptions applicable to a system. It describes the configuration that produced the new
operating-system image (OSIMAGE). For G-series systems, the CONFTEXT file
consists of one or two paragraphs: DEFINES (optional) and ALLPROCESSORS
because SCF configures all peripheral devices and I/O processes. Tandem recommends
that the user make changes to a copy of the CONFTEXT file only, and not the
CONFAUX file.
CSG. See Client Server Gateway (CSG).
DAL. See Data Access Language (DAL) server.
Data Access Language (DAL) server. A host-based data server process running on a
Tandem system that uses both Structured Query Language (SQL) and Data Access
Language (DAL) features. It provides Macintosh users on attached LANs with reliable,
transparent, fault-tolerant, distributed access to data residing in Tandem NonStop
SQL/MP databases.
data-ready site. A backup site similar to an operational-ready site except that data-ready sites
take advantage of electronic vaulting. Data-ready sites are updated on a staged basis.
Archived data resides on the data-ready site systems and does not need to be loaded
during a disaster. The data-ready site systems are only as current as the last data loaded
onto the systems.
DCOM. See Disk Compression Program (DCOM).
define process library. A set of TACL routines that allow you to run background server
processes so that management applications can send commands to a number of
subsystems without the overhead of creating a new server process for each command.
design outage class. An outage class that includes bugs in design and design failures in
hardware and software. An example of the class of outage could be an application
change that introduces unexpected problems. See also outage class.
Disk Compression Program (DCOM). A utility program that compresses disk space.
Disk Space Analysis Program (DSAP). A utility program that analyzes how space on a
given disk volume is used.
