1 Introduction
1.1 About Oracle GoldenGate Monitor
Oracle GoldenGate Monitor is a real-time, web-based monitoring console for the Oracle GoldenGate replication solution. Oracle GoldenGate Monitor delivers an at-a-glance, graphical view of all of the Oracle GoldenGate instances and their associated databases within your enterprise. Instantly, you can view statistics, targeted views, and alerts that will help you to monitor the performance of all of the objects in the Oracle GoldenGate configuration and detect problems, such as lag or abended processes, the moment that they occur. Oracle GoldenGate Monitor can send alert messages to its own console workspaces, as well as to email, SNMP, and CLI clients.
1.2 Oracle GoldenGate Monitor Architecture
Oracle GoldenGate Monitor uses a browser-based graphical user interface to monitor Oracle GoldenGate instances remotely. It includes the components shown in the diagram.
1.2.1 Oracle GoldenGate
An Oracle GoldenGate Monitor Server communicates with one or more Oracle GoldenGate instances using Java Management Extensions (JMX). The Manager process for each Oracle GoldenGate instance is associated with an Oracle GoldenGate Agent that supplies information about the instance to the Oracle GoldenGate Monitor Server.
1.2.2 Oracle GoldenGate Agent
An Oracle GoldenGate Agent is installed with each Oracle GoldenGate instance. It collects information about the instance and sends it to the Oracle GoldenGate Monitor Server. The Oracle GoldenGate Monitor Agent is installed separately from Oracle GoldenGate Monitor. It operates in one of two modes, Oracle GoldenGate Monitor Server or Oracle GoldenGate Enterprise Management Plug-In. For those installation and configuration procedures, see Oracle GoldenGate Installing and Configuring Oracle GoldenGate Monitor Agent.
1.2.3 Oracle GoldenGate Monitor Server
The Oracle GoldenGate Monitor Server coordinates the monitoring of multiple Oracle GoldenGate instances. The Oracle GoldenGate Monitor Server is a Java application that:
-
processes information from Oracle GoldenGate Agents and communicates it to the web browser and
-
manages users, history, the display of information, and notifications triggered by events.
