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. DES See Data Encryption Standard. 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.
