devices.
subvolume. A related set of files, as defined by the user, within the Guardian environment.
The name of a subvolume is the third of the four parts of a file name.
SuperCTL file. The file that provides centralized configuration and control for a
Pathway/XM environment. The SuperCTL file is built by the PXMCFG utility in
accordance with PXMCFG statements in a configuration source file. The PXMCOM
utility uses and modifies the SuperCTL file as it starts up and manages the Pathway/XM
environment.
swap file. A temporary file created by a process for temporary storage: for example, by the
Kernel Managed Swap Facility (KMSF) on behalf of a TCP for temporary storage of
terminal context.
syncdepth. A parameter to Guardian procedure calls that sets the maximum number of
operations or messages that a process is allowed to queue before action must be taken or
a reply must be performed.
sync ID. A value used in the Guardian environment to determine whether an I/O operation
has finished. In active backup programming, a file’s sync ID is used to prevent the
backup process from repeating I/O operations that have already been completed by the
primary process.
system name. (1) The first of the four parts of a Guardian file name; also called a node name.
(2) A name that identifies the NonStop™ Himalaya system on which a PATHMON
