HP Application Recovery Manager software A.06.10 Concepts guide (March 2008)

tablespace A part of a database structure. Each database is logically
divided into one or more tablespaces. Each tablespace has data
files or raw volumes exclusively associated with it.
target volume (ZDB specific term) A storage volume to which data is replicated.
Terminal Services (Windows specific term) Windows Terminal Services provide a
multi-session environment that allows clients to access a virtual
Windows desktop session and Windows-based programs
running on the server.
thread (Microsoft SQL Server specific term) An executable entity that
belongs to only one process. It comprises a program counter,
a user-mode stack, a kernel-mode stack, and a set of register
values. Several threads can run at a time within one process.
TNSNAMES.ORA (SAP R/3 specific term) A network configuration file that contains
connect descriptors mapped to service names. The file may be
maintained centrally or locally, for use by all or individual clients.
transaction A mechanism for ensuring that a set of actions is treated as a
single unit of work. Databases use transactions to keep track of
database changes.
transaction backup Transaction backups generally use fewer resources than
database backups, so they can be created more frequently than
database backups. By applying transaction backups, you can
recover the database to a specific point in time prior to when
a problem occurred.
transaction log
backup
Transaction log backups generally use fewer resources than
database backups so they can be created more frequently than
database backups. By applying transaction log backups, you
can recover the database to a specific point in time.
transaction log
files
Files that record transactions of the database modifications, and
provide fault tolerance in case of a database disaster.
transaction logs (Application Recovery Manager specific term) Keep track of IDB
changes. The archiving of transaction logs should be enabled
to prevent you from losing the transaction log files that are
created after the last IDB backup and are necessary for IDB
recovery.
