system configuration database
system configuration database. The database file on the $SYSTEM.ZSYSCONF
subvolume that contains configuration information for all system objects that can be
configured by the Subsystem Control Facility (SCF). Configuration information for all
system objects that can be configured during system generation is contained on the
$SYSTEM.SYSnn subvolume. See also configuration file
and SYSnn subvolume.
system enclosure. An enclosure for system components. Processor enclosures and I/O
enclosures are both system enclosures. Contrast with peripheral enclosure
.
TCP. See Transmission Control Protocol (TCP).
TCP/IP. See Transmission Control Protocol/Internet Protocol (TCP/IP).
terabyte (TB). A unit of measurement equal to 1,099,511,627,776 bytes (1024 gigabytes).
See also gigabyte (GB), kilobyte (KB), and megabyte (MB).
TNS library. A single, optional, TNS-compiled loadfile associated with one or more
application loadfiles. If a user library has its own global or static variables, it is called a
TNS shared run-time library (TNS SRL). Otherwise it is called a User Library (UL).
TNS loading. A task performed at process startup time when executing a TNS object file.
This task involves mapping the TNS instructions, procedure entry point (PEP) table,
and external entry point (XEP) table from a TNS object file into memory.
TNS shared run-time library (TNS SRL). A shared run-time library (SRL) available to TNS
processes in the Open System Services (OSS) environment. A TNS process can have
only one TNS SRL. A TNS SRL is implemented as a special user library that allows
shared global data.
TNS system library. A collection of HP-supplied TNS-compiled routines available to all
TNS processes. There is no per-program or per-process customization of this library.
All routines are immediately available to a new process; no dynamic loading of code or
creation of instance data segments is involved. See also native system library.
TNS/R library. A TNS/R native-mode library. For a PIC-compiled application, TNS/R
libraries can be dynamic-link libraries (DLLs) or hybridized native shared runtime
libraries (SRLs). For a non PIC-compiled application, TNS/R libraries can only be
native SRLs.
TNS/R native shared run-time library (TNS/R native SRL). A shared run-time library
(SRL) available to TNS/R native processes in both the Guardian and Open System
Services (OSS) environments. TNS/R native SRLs can be either public or private. A
TNS/R native process can have multiple public SRLs but only one private SRL.
Transmission Control Protocol (TCP). A connection-oriented protocol that provides for the
reliable exchange of data between a sending and a receiving system. TCP implements
functions corresponding to the Open Systems Interconnections (OSI) Reference
model-layer 4, the transport layer.
