Configuring HP Serviceguard Toolkit for Oracle Data Guard

Metrocluster and EDC configurations
Metrocluster is an HP high availability product for Serviceguard customers who require integrated
disaster recovery solutions. HP Metrocluster uses Serviceguard clustering technology to form a
single cluster of systems that are located apart from each other at different data centers at
metropolitan distances.
While Metrocluster provides storage-based replication of data across metropolitan distances,
organizations often like to build in additional data replicas, either locally or at other data centers.
Having both storage replication and ODG replication can help to safeguard customer data. The
integration of ODG with Metrocluster or EDC gives organizations this choice.
