communication among program
components in a network using objects.
Prior to IBM Tivoli Monitoring v6.2.3, the
Tivoli Enterprise Portal Server is a
CORBA implementation.
Configure History permission
Your user ID must have Configure
History permission to open the History
Collection Configuration window for
setting up history files and data rolloff. If
you do not have this permission, you will
not see the menu item or tool for
historical configuration.
Configuration Tool, z/OS (ICAT)
A REXX-based tool for configuring
OMEGAMON XE products running on
zSeries systems, once they have been
installed using the System Modification
Program/Extended (SMP/E) tool.
CORBA
See Common Object Request Broker
Architecture.
critical state
The indication that a situation associated
with a Navigator item is in an
unacceptable state and that you must take
corrective action. The critical state is
represented by the color red.
Custom Navigator Views permission
Your user ID has a Modify checkbox for
the Custom Navigator Views feature. This
permission must be enabled for you to
open the Navigator view editor to
maintain and update Navigator views.
Data Encryption Standard
A widely used method of private-key
data encryption that originated at IBM in
1977 and was adopted by the U.S.
Department of Defense. DES supports 72
quadrillion or more possible encryption
keys; for each message, the key is chosen
at random from among this enormous
number of possible keys. Like all other
private-key cryptographic methods, both
the sender and the receiver must know
and use the same private key.
DES applies a 56-bit key to each 64-bit
block of data. Although this is considered
strong encryption, many companies use
triple DES, which applies three keys in
succession.
datasource name
The name that is stored in the database
server and that enables you to retrieve
information from the database through
ODBC. The DSN includes such
information as the database name,
database driver, user ID, and password.
datasources
Data pertaining to J2EE data sources,
which are logical connections to database
subsystems.
DB2 on the workstation
IBM's DB2 Database for Linux, UNIX, and
Windows systems is a relational database
management system that runs on desktop
computers. You install a DB2 database on
the same system as the Tivoli Enterprise
Portal Server; it stores the portal queries,
customized workspaces, user IDs, and
custom Navigator views. DB2 on the
workstation can also serve as the data
repository for the Tivoli Data Warehouse,
which stores historical monitoring
information.
Demilitarized Zone
The area of a Worldwide Web application
that enables a company to host Internet
services without allowing unauthorized
access.
Derby An open-source, public-domain, relational
database management system
implemented in Java and designed to
conform to accepted database standards
(such as SQL and JDBC). Derby came
about when IBM contributed its
Cloudscape database manager to the
Apache project and features a small
machine footprint. IBM Tivoli Monitoring
implements Derby as an embedded
database within the Tivoli Enterprise
Portal Server extended services (TEPS/e),
and runs within the portal server's Java
virtual machine.

desktop client
Software supplied with IBM Tivoli
Monitoring that you install on a
workstation that you plan to use for
interacting with the Tivoli Enterprise
Portal Server and the Tivoli Enterprise
Monitoring Server. The Tivoli Enterprise
