breakpoint
breakpoint. An object code location at which execution will be suspended so that you can
interactively examine and modify the process state. With symbolic debuggers,
breakpoints are usually at source line or statement boundaries.
In TNS/R or TNS/E native object code, breakpoints can be at any MIPS RISC
instruction or Intel® Itanium® instruction within a statement. In a TNS object file that
has not been accelerated, breakpoints can be at any TNS instruction location. In a
TNS object file that has been accelerated, breakpoints can be only at certain TNS
instruction locations (see memory-exact point), not at arbitrary instructions. Some
source statement boundaries are not available. However, breakpoints can be placed at
any instruction in the accelerated code.
CAID. See creator access ID (CAID).
central processing unit (CPU). Historically, the main data processing unit of a computer.
HP NonStop™ servers have multiple cooperating processors rather than a single CPU.
See also processor.
child process. A process created by another process. The creating process becomes the
parent process of the new process. See also pathname component.
CISC compiler. See complex instruction-set computing (CISC) and TNS compiler
CISC processor. An instruction processing unit (IPU) that is based on complex
instruction-set computing (CISC) architecture.
checkpoint. A line in a program at which specified information is copied from the primary
process of a process pair to the backup process. This line then becomes the restart
point for the backup process in the event that the primary process should stop due to
processor failure.
child process. A process created by the current process.
CISC. See complex instruction-set computing (CISC)
.
client. A software process, hardware device, or combination of the two that requests
services from a server. Often, the client is a process residing on a programmable
workstation and is the part of an application that provides the user interface. The
workstation client might also perform other portions of the application logic.
client application. An application that requests a service from a shared memory
. Execution
of remote procedure calls is an example of a client application.
code file. See object code file.
code segment. A segment that contains executable instructions of a program or library to
be executed plus related information. Code segments can be executed and also
accessed as read-only data but not written to by an application program. These read-
only and execute-only segments are efficiently shared among simultaneous executions
