shared run-time library (SRL)
shared run-time library (SRL). A collection of procedures whose code and data can be
loaded and executed only at a specific assigned virtual memory address (the same
address in all processes). SRLs use direct addressing and do not have run-time
resolution of links to and from the main program and other independent libraries. SRLs
are not supported on TNS/E systems. Contrast with dynamic-link library (DLL).
SRL. See shared run-time library (SRL).
stub. In a remote procedure call (RPC), a code module specific to an RPC interface that is
generated by the DCE Interface Definition Language compiler to support remote
procedure calls for the interface. RPC stubs are linked with client and server
applications and hide the intricacies of remote procedure calls from the application
code. See also remote procedure call (RPC) and Interface Definition Language (IDL).
SQL. See structured query language (SQL).
SRL. See shared run-time library (SRL).
structured query language (SQL). A nonprocedural language for defining and accessing
relational databases. See also HP NonStop SQL/MP.
TCP/IP. See Transmission Control Protocol/Internet Protocol (TCP/IP).
thread. A sequential flow of control within a process.
TMF. See transfer syntax.
transaction demarcation interface. An application program interface for indicating
transaction boundaries, including transaction start and transaction commit.
transfer syntax. In a remote procedure call (RPC), a set of encoding rules used for
transmitting data over a network and for converting application data to and from
different local data representations. See also network data representation (NDR).
Transmission Control Protocol/Internet Protocol (TCP/IP). A network provider that is
supported by the transport layer interface.
transport protocol. A communications protocol from the transport layer of the Open
System Interconnect (OSI) network architecture, such as the Transmission Control
Protocol (TCP) or the User Datagram Protocol (UDP).
Universal Unique Identifier (UUID). In a remote procedure call (RPC), an identifier
generated using both time and network address information, such that no matter when
or where it is generated it is guaranteed to be unique. UUIDs are generated by the
uuidgen utility. UUIDs are used extensively within DCE to identify various objects
within the system. UUIDs have both an internal and external (print) format.
UUID. See Universal Unique Identifier (UUID).
