situations and policies that use that list are redistributed to all managed systems in the list. MBeans Managed beans are Java objects that represent managed resources such as devices, services, and applications. The management functions are provided by the MBean server. Microsoft Management Console This feature of Microsoft's various Windows Server environments provides a centralized, consistent, and extensible interface to Windows' various monitoring and management utilities. In particular, MMC manages directory services, job scheduling, event logging, performance monitoring, and user environments. middleware Software that enables the exchange of information between components in a distributed computing environment. The middleware is the data-exchange and communications channel that allows programs to cooperate with each other without having to know details about how they are implemented or where they are deployed. Middleware typically provides a range of related facilities such as persistence, auditing, and the ability to build a transactional unit of work. IBM's CICS and WebSphere MQ are examples of middleware. migrating Preserving your customized configuration data so that you can use it again after installing a newer version of the product. MMC See Microsoft Management Console. monitor interval A specified time, scalable to seconds, minutes, hours, or days, for how often the Tivoli Enterprise Monitoring Server checks to see if a situation has become true. The minimum monitor interval is 30 seconds; the default is 15 minutes. NAT See Network Address Translation. Navigator The upper-left pane of the Tivoli Enterprise Portal window. The Navigator Physical view shows your network enterprise as a physical hierarchy of systems grouped by platform. You can also create other views to create logical hierarchies grouped as you specify, such as by department or function. Network Address Translation A scheme used by local-area networks (LANs) to establish an internal and external set of IP addresses. Internal IP addresses are kept private and must be translated to and from the external addresses for outbound and inbound communications. NAT is often used in firewall configurations. node (1) One computer in a computer network. (2) Any managed system, such as an AIX-based pSeries server, that IBM Tivoli Monitoring is monitoring. A node can also be a managed system of subnodes, all of which are being managed as components of the primary node. non-agent bundles These custom bundles let you remotely deploy components that need not connect to a Tivoli Enterprise Monitoring Server, such as those that support other Tivoli products like Netcool/OMNIbus. object An instance of a class, which comprises an implementation and an interface. An object reflects its original, holding data and methods and responds to requests for services. CORBA defines an object as a combination of state and a set of methods characterized by the behavior of relevant requests. ODBC See Open Database Connectivity. OMEGAMON Dashboard Edition ( DE) The OMEGAMON implementation that includes all the features of the Tivoli Enterprise Portal provided with OMEGAMON XE, plus application-integration components that facilitate an enterprise-wide view of your computing environment. OMEGAMON DE's workspaces integrate the data from multiple OMEGAMON Monitoring Agents into one network-wide view. OMEGAMON Extended Edition ( XE) The IBM Tivoli Monitoring implementation of a single OMEGAMON monitoring agent. OMEGAMON XE displays the monitoring data from each OMEGAMON monitoring agent Glossary 277
