Managing Very Large Grids The Grid Control framework uses the Oracle 10g technology stack. For large grids with many administrators, the Grid Control framework scales well.

•

Oracle Management Repository can be installed in a Real Application Cluster.

•

OMS can take advantage of Oracle Application Server 10g clustering.

High Availability Configurations The architecture for deploying Grid Control in a highly available fashion is based on two key concepts:

• •

Redundancy Component monitoring
