NonStop Server for Java (NSJ) Programmer's Guide (NSJ 2.1+)
complex instruction set computing (CISC)
A processor architecture based on a large instruction set, characterized by numerous
addressing modes, multicycle machine instructions, and many special-purpose
instructions. The goal of CISC design is to minimize the size of a program's machine
code, minimize the number of program instructions fetched, use relatively few registers,
and tolerate relatively dumb compilers. On TNS/R machines, CISC refers in particular to
the stack-oriented, 16-bit instruction set carried over from TNS machines such as the
NonStop VLX system. Compare to RISC.
concurrency
A condition in which two or more transactions act on the same record in a database at the
same time. To process a transaction, a program must assume that its input from the
database is consistent, regardless of any concurrent changes being made to the database.
TMF manages concurrent transactions through concurrency control.
concurrency control
Protection of a database record from concurrent access by more than one process. TMF
imposes this control by dynamically locking and unlocking affected records to ensure that
only one transaction at a time accesses those records.
conformant
A Java implementation is conformant if it passes all the tests in the JCK.
CORBA
See Common Object Request Broker Architecture (CORBA).
Core API
The minimal set of APIs that developers can assume is present on all delivered
implementations of the Java Platform when the final API is released by Sun
Microsystems, Inc. NonStop Java conforms to every Core API in the JDK except AWT.
Core API is also called Java Core Classes and Java Foundation Classes. See also
Standard Extension API.
CPP
See Cryptography Package Provider (CPP).
Cryptography Package Provider (CPP)
An implementation of concrete classes for security, usually provided by a security vendor
such as RSA Data Security or Atalla, which addresses such needs as digital signatures,
key certificate management, and access control.
CyberWeb
