allows you to format a document as a data structure. As program objects, such documents can have their contents and data hidden within the object, which allows you to control who can manipulate the document and how. In addition, documents can carry with them the object-oriented procedures called methods. The XML standard aids in exchanging data between applications and users. filter criteria These limit the amount of information returned to the data view in response to a query. You can apply a prefilter to the query to collect only certain data, or apply a postfilter to the view properties to show only certain data from the information collected. georeferenced map A special type of graphic that has built-in knowledge of latitude and longitude and can be zoomed into and out of quickly. The Tivoli Enterprise Portal uses proprietary .IVL files generated with the map-rendering component. These files cannot be opened or saved in a graphic editor. GSKit The Global Security Toolkit provides SSL (Secure Sockets Layer) processing within protocols such as SPIPE and HTTPS. On z/OS systems, GSKit is known as the Integrated Cryptographic Service Facility, or ICSF. historical data management The procedures applied to short-term binary history files that roll off historical data to either the Tivoli Data Warehouse or to delimited text files (the krarloff utility on UNIX or Windows; jobname KPDXTRA for the z/OS Persistent Datastore), and then delete entries in the short-term history files over 24 hours old, thereby making room for new entries. hot standby A redundant Tivoli Enterprise Monitoring Server that, if the primary or hub should fail, assumes the responsibilities of the failed monitoring server. HTTP The Hypertext Transfer Protocol is a suite of Internet protocols that transfer and display hypertext documents within web browsers. HTTP sessions Data related to invocations of specific Worldwide websites. HTTPS The Secure Hypertext Transport Protocol is an implementation of the Hypertext Transport Protocol (HTTP) that relies on either the Secure Sockets Layer (SSL) API or the Transport Layer Security (TLS) API to provide your users with secure access to your site's web server. These APIs encrypt and then decrypt user page requests as well as the pages returned by the Web server. hub (1) A central host system that collects the status of situations running on your systems. (2) The Tivoli Enterprise Monitoring Server that your site has selected to act as the focal point to which the Tivoli Enterprise Portal Server and all remote monitoring servers in this monitored network connect. A remote monitoring server passes its collected data to the hub to be made available to clients, creating an enterprise-wide view. IBM Tivoli Monitoring A client/server implementation for monitoring enterprise-wide computer networks that comprises a Tivoli Enterprise Monitoring Server, an application server known as the Tivoli Enterprise Portal Server, one or more Tivoli Enterprise Portal clients, and multiple monitoring agents that collect and distribute data to the monitoring server. IIOP See Internet Inter-ORB Protocol. integral web server A proprietary web server developed for IBM Tivoli Monitoring that is installed and configured automatically with the Tivoli Enterprise Portal Server. You enter the URL of the integral web server to start the Tivoli Enterprise Portal client in browser mode. Internet Inter-ORB Protocol An Internet communications protocol that runs on distributed platforms. Using this protocol, software programs written in different programming languages and running on distributed platforms can communicate over the Internet. Glossary 275
