PM, LM, PROGTERM, and TCPTERM are object types in the SPI interface.
OLTP. See online transaction processing (OLTP).
OLTP application. See online transaction processing (OLTP) application.
online transaction processing (OLTP). A method of processing transactions in which
entered transactions are immediately applied to the database. The information within
the database is readily available to all users through online screens and printed
reports. The transactions are processed while the requester waits, as opposed to
queued or batched transactions, which are processed at a later time. Online
transaction processing can be used for many different kinds of business tasks such as
order processing, inventory control, accounting functions, and banking operations. See
also batch processing.
online transaction processing (OLTP) application. A set of programs that perform online
transaction processing (OLTP) tasks on behalf of the user. With an OLTP application,
many terminal users can update data simultaneously, recording the changes in the
database as they are entered. OLTP applications generally display, check, and accept
input data; manipulate the input data; and perform some type of data-output activity.
Open System Services (OSS). An open system environment available for interactive or
programmatic use with the Tandem NonStop Kernel. Processes that run in the OSS
environment use the OSS application program interface; interactive users of the OSS
environment use the OSS shell for their command interpreter. See also Guardian and
Guardian environment.
OSS. See Open System Services (OSS).
OSS environment. The NonStop Kernel Open System Services (OSS) API, tools, and
utilities. See also Open System Services (OSS).
OSS filename. A component of an OSS pathname containing any valid characters other
than a slash (/) or a null. See also file name, OSS pathname, and file system
(definition 2).
OSS operating environment. See OSS environment.
OSS pathname. The string of characters that uniquely identifies a file within its file system
in the OSS environment. A pathname can be either absolute or relative. See also
absolute pathname, relative pathname, and file system (definition 2).
OSS username. A string that uniquely identifies a user within the user database for a node.
overlay area. In SCREEN COBOL, an area of a base screen within which an overlay
screen can be displayed.
