6.4 Monitoring True Cache with Oracle Enterprise Manager

You can discover, monitor, and manage Oracle True Cache in Oracle Enterprise Manager.

True Caches can be discovered in Enterprise Manager manually or using Auto Discovery. For details, see Discovering and Adding True Cache in Oracle Enterprise Manager Monitoring Guide.

Once the primary database and True Caches are discovered and added, you can use Enterprise Manager to monitor their health and performance. If you have configured multiple True Caches for a single primary (a one-to-many setup), you can use Enterprise Manager to view the topology and obtain a comprehensive overview of the primary database and all its associated True Caches. From the Configuration Topology view, you can navigate to the Home page of a True Cache to view graphs that display transport lag, apply lag, and hit ratios. This lets you assess how current and efficient the cache is.

In addition, Enterprise Manager provides standard database performance and usage metrics and key True Cache-specific metrics. True Cache metrics in Enterprise Manager include Database Load, Memory Usage, and True Cache Hit Ratios and Lags. Having these metrics readily available in the user interface enables you to quickly detect performance degradations and lag, and proactively fix issues. For details on the True Cache metrics in Enterprise Manager, see True Cache in Oracle Enterprise Manager Oracle Database Metric Reference Manual.
