Tandem application environment
Tandem application environment. An environment that enables you to develop and run
high-performance, high-volume, online transaction-processing (OLTP) applications on
NonStop systems. NonStop Transaction Services/MP (NonStop TS/MP), NonStop
SQL/MP, and NonStop Transaction Manager/MP (NonStop TM/MP) are the three key
products that make up the Tandem application environment.
Tandem DAL Server. See Tandem Data Access Language (DAL) Server.
Tandem Data Access Language (DAL) Server. A client/server product that provides
NonStop SQL/MP database access for client applications compatible with DAL. DAL is
a connectivity language and a standard for database access.
Tandem Service Management (TSM). A client/server application that provides
troubleshooting, maintenance, and service tools for your Himalaya S-series server. TSM
combines many of the system maintenance functions previously provided by the
Syshealth toolkit, the Tandem Maintenance and Diagnostic Subsystem (TMDS), and the
Remote Maintenance Interface (RMI) product.
TCP. See Terminal control process (TCP).
Terminal control process (TCP). A multithreaded process supplied with Pathway/TS that
interprets and executes screen program instructions for each input/output (I/O) device or
process the TCP is configured to handle. The TCP coordinates communication between
screen programs and their I/O devices or processes and, with the help of the PATHMON
process, establishes links between screen programs and Pathway server processes.
TMF catalog. The database that specifies where all dumped files reside and which dump
media are available for reuse.
TMF subsystem. The Transaction Management Facility, which is the major component of
the NonStop Transaction Manager/MP product. The TMF subsystem manages database
transactions, keeps track of database activity through audit trails, and provides database
recovery methods.
TMFCOM. The NonStop Transaction Manager/MP interactive interface. TMFCOM allows
operators to enter commands and receive responses through a terminal keyboard and
monitor.
TMFSERVE process. The process that provides access to the TMF subsystem through the
Subsystem Programmatic Interface (SPI), making it possible to construct management
applications that monitor and control the TMF environment. TMFSERVE also receives
and acts upon commands entered through TMFCOM.
transaction. An explicitly delimited operation or set of related operations that alters the
content of a database.
TSM. See Tandem Service Management (TSM).
