Generic Data Service Concepts

The GDS is a mechanism for making simple network-aware and non-network-aware applications highly available or scalable by plugging them into the Oracle Solaris Cluster Resource Group Management (RGM) framework. This mechanism does not require you to code a data service, which you typically must do to make an application highly available or scalable.

The GDS is a single, precompiled data service. You cannot modify the precompiled data service and its components, the callback method (rt_callbacks) implementations, and the resource type registration file (rt_reg).

This section covers the following topics:

• Precompiled Resource Type

• Advantages and Disadvantages of Using the GDS

• Ways to Create a Service That Uses the GDS

• How the GDS Logs Events

• Required GDS Properties

• Optional GDS Properties
