core file
core file. See saveabend file.
correctable memory error (CME). An error caused by incorrect data at a particular
memory location. The cause of the error is such that the error is automatically
corrected by the system. Contrast with uncorrectable memory error (UCME)
.
COUP. See Configuration Utility Program (COUP).
CPU. See central processing unit (CPU).
cpu, pin. In the Guardian environment, a number pair that uniquely identifies a process
during the lifetime of the process, consisting of the processor (CPU) number and the
process identification number (PIN). See also PID
.
CRC. See cyclic redundancy check (CRC).
creation version serial number (CRVSN). In the Open System Services (OSS)
environment, a number assigned by a disk process when a file is created. The CRVSN
is used by the disk process and the OSS name server process to verify that the correct
file is accessed. The CRVSN is stored in the catalog entry for an OSS regular file and
is passed to the disk process when a Data Definition Language (DDL) request that
involves the file is made.
critical load. Equipment that must have an uninterruptible power input to prevent damage
to the equipment or the facility or prevent injury to personnel.
CRPC. See computer-room power center (CRPC).
CRU. See customer-replaceable unit (CRU).
CRVSN. See creation version serial number (CRVSN).
CSQ. See conformance statement questionnaire (CSQ).
current. The movement of electrons caused by potential difference between two
electromotive charge forces.
current configuration file. See configuration file.
current working directory. In the Open System Services (OSS) environment, the directory
used in pathname resolution of relative pathnames. A process always has a current
working directory. See also working directory
.
CUSTFILE. An EDIT file included on every site update tape (SUT) as
$SYSTEM.A
nnnnnn.CUSTFILE, where nnnnnn is the system serial number of the
target system. The CUSTFILE contains information on the software products on the
SUT, their related files, and the destination and use of each file. HP customizes
information in the CUSTFILE for each customer’s system.
customer engineer (CE). See service provider.
