NonStop Open Database Connectivity (ODBC)
Server
NonStop Open Database Connectivity (ODBC) Server. A client/server product that allows
client applications that use either the ODBC interface or the SQL Server interface to
access NonStop SQL/MP databases. ODBC is a database connectivity standard
developed by the SQL Access Group (SAG). SQL Server is a de facto standard.
NonStop SQL/MP. The Tandem relational-database-management system that promotes
efficient online access to large distributed databases. NonStop SQL/MP is the Tandem
implementation of the Structured Query Language (SQL).
NonStop TM/MP. See NonStop Transaction Manager/MP (NonStop TM/MP).
NonStop Transaction Manager/MP (NonStop TM/MP). A data-management product that
maintains the consistency of a database and provides the tools for database recovery.
NonStop Transaction Services/MP (NonStop TS/MP). A Tandem product that provides
process-management and link-management functions for OLTP applications.
NonStop TS/MP. See NonStop Transaction Services/MP (NonStop TS/MP).
NonStop TS/MP and Pathway/TS management programming interface. A set of
programmatic commands that allow you to write management application programs that
communicate directly with the NonStop TS/MP central control process (PATHMON) for
configuration and control operations. This interface is based on the Subsystem
Programmatic Interface (SPI) portion of Distributed Systems Management (DSM).
object. Any entity subject to independent reference or control by one or more subsystems.
Examples of objects are devices, communications lines, processes, and files. In
Distributed Systems Management (DSM), every object has a name and type.
offline. Used to describe tasks that require the NonStop system to be shut down.
offline change. Any change that requires your NonStop system to be shut down. Offline
changes are usually performed during a planned outage.
OM model. See operations-management (OM) model.
online. Used to describe tasks that can be performed while the NonStop system is
operational.
online change. Any change that can be performed while your NonStop system is still
operational. In some situations, online changes may temporarily affect application
availability. For example, altering the characteristics of a communications line may
temporarily affect applications that use that communications line.
online dump. A copy of an audited database file written to tape or disk. The TMF subsystem
can restore the online-dump files to disk and apply the audit-trail images to reconstruct
the files on the volume.
