file
F
file. The physical storage for a set of related records in an Enscribe database. Also, the
physical storage for a NonStop SQL table or index (the creation of a table or index
implicitly creates a file with the same name as the table or index).
file recovery. The process of reconstructing specified audited files when the current copies
on the audited volume are not usable. A file could become unusable for a variety of
reasons, including:
File recovery includes restoring online dumps from tape to disk, applying the after-
images from the audit trail to the database records, and then backing out all
transactions that were incomplete at the time of the system interruption or failure.
File Utility Program (FUP). A software product that performs operations on files stored on
disk drives and tape volumes. You can request several TMF-related functions through
FUP commands.
foreign. Pertaining to a different environment. In transaction processing, a foreign
transaction manager is a different type of transaction manager, and a foreign
transaction or transaction branch is one processed by a different type of transaction
manager.
format 1. A disk partition format that can be up to approximately 2 GB in size. This is the
default partition format.
format 2. A disk partition format that can be up to 1024 GB in size. Enscribe files that
contain format 2 partitions are sometimes referred to as Big Files.
format 2-enabled table. A SQL table that can have format 2 partitions, format 1 partitions,
or a mixture of the two.
G
gateway. A process or set of processes that supports distributed transaction processing by
providing communication between different transaction-processing environments. In a
NonStop Kernel operating system environment, a gateway supports communication
between TMF and a foreign transaction manager.
