7.5.1 HACMP, logical partitions and WebSphere
HACMP can be used with logical partitions (LPARs) to...
- Fail over application server instances from one server to another in the event of a failure
- Make the Cell Manager and Node Manager administrative processes highly available
- Allocate and release CPU and memory on the LPARs when application servers are started and stopped on the LPARs.
- Request extra resources from CPUoD if there are not enough system resources to fulfill a request.
This section provides a suggested process for configuring WAS Network Deployment V6 in an HACMP environment. It does not document the complete HACMP setup, including planning, designing, customization, installation, and configuration.
