Definition of terms

Terms	Definition
CFS	Cluster File System allows multi-system shared access to common file system.
Complex workload	A multi-instance application that uses active resources across multiple nodes in a cluster.
package	These workloads are configured using multiple inter-dependent multi-node or failover packages in a cluster.
	The workloads need to be managed and moved collectively for disaster tolerance.
MNP	Multi-node package, a Serviceguard package that runs on multiple nodes at the same time and can be
	independently started and halted on individual nodes.
OC	Oracle Clusterware can run in conjunction with Serviceguard Extension for RAC and can provide Oracle
	cluster membership and resource management services.
OCR	Oracle Cluster Registry
RAC	Real Application Cluster enables a multi-instance concurrent shared access database.
SADTA	SADTA enables deploying complex workloads in a Metrocluster. Complex workloads are applications
	configured using multi-node and failover packages with dependencies. These packages, referred to as
	complex workload packages, are configured over isolated sub-clusters, such as Oracle Clusterware, or
	Serviceguard Storage Management Suite (SG SMS) Cluster File System, which are created within the
	Metrocluster. Sub-clusters have access only to the storage arrays within their respective sites.
SG SMS	Serviceguard Storage Management Suite Software
SGeRAC	Serviceguard Extension for RAC extends Serviceguard to support Oracle RAC.
SGeSAP	Serviceguard Extension for SAP extends Serviceguard to support SAP NetWeaver environments.
Site controller	A Metrocluster failover package to provide coordinated automatic site failover for the configured complex
package	workload. It is created using a Metrocluster modular package module: dts/sc.

Cluster Easy Deployment

Introduction

Cluster Easy Deployment is targeted to simplify and speed up the process of bringing up a new cluster, with a lower level of required expertise.

This cluster Easy Deployment feature is supported by both Serviceguard Manager and the Serviceguard command-line interface.

In Serviceguard Manager, this feature simplifies cluster configuration with various environments, by providing an interactive wizard, bolstered with ample auto discovery.

Cluster Easy Deployment is also supported on the command line with the cmdeploycl command. This command eases cluster-related storage and network configuration aspects.
