requester
requester. A process or program that runs in the NonStop Kernel operating system
environment on a NonStop system and requests services from a server process. For
example, a SCREEN COBOL program is a requester program, and the Pathway
terminal control process (TCP) is the requester process that interprets such a
requester program. Alternatively, a requester program can make requests through
procedure calls to the Pathsend facility or through the NonStop Kernel WRITEREAD
procedure. A requester is a specific type of client. See also client and server.
resource manager. A representation of anything that contains data, such as a database or
a queue.
TMF uses a resource manager facility that is a collection of routines that enables
cooperation between different transaction management systems running on different
platforms in support of heterogeneous transaction processing. See also recoverable
resource manager and volatile resource manager.
resource manager file. A file associated with each resource manager, used to manage and
control various elements.
restore-audit volume. A disk volume on the local system used to receive audit-trail files
restored from an audit dump on tape as part of a recovery procedure. The system
manager can configure up to 16 restore-audit volumes. Any disk volume can be
configured as a restore-audit volume, including volumes configured for other TMF
purposes.
rollover. See audit-trail rollover.
round-robin. An option to the TMFCOM ALTER CATALOG command in response to which,
when set, TMF selects tapes by going through the list of available tapes completely
before starting over again. When this option is not set, TMF starts from the beginning
of the list every time it must select a tape to use.
runaway transaction. A transaction that, because of an application error, makes changes
to a very large number of records in a database. Such transactions can generate
enormous amounts of audit information; even if they do not, however, they retain (pin)
a large number of audit trail files on disk.
