OGG Enterprise Manager Plug-in (Live)

12Replication Technology Evolution for ATLAS Data Workshop

For installing the plug-in:

o Enterprise Manager Cloud Control 12c Bundle Patch 1 (12.1.0.1) and latero Oracle GoldenGate 11g Release 2 (11.2.1.0.1) and later

Management features:

o Monitor Oracle GoldenGate instances.o Gather configuration data and track configuration changes for Oracle

GoldenGate instances.o Raise alerts and violations based on thresholds set on monitored targets

and configuration data.o Support monitoring by a remote Agent. A Local Agent is an agent running on

the same host as the Oracle GoldenGate instance.
