Overview

Language:

The PeopleSoft application server data service provides orderly startup, shutdown, fault monitoring, and automatic failover of a PeopleSoft application server domain. The PeopleSoft process scheduler data service manages the start, shutdown, and fault monitoring of a specific process scheduler domain.

Use the information in this section to understand how HA for PeopleSoft Enterprise makes PeopleSoft Enterprise highly available.

HA for PeopleSoft Enterprise provides fault monitoring and automatic failover for the PeopleSoft Enterprise application to eliminate single points of failure in a PeopleSoft Enterprise system. Any PeopleSoft Enterprise application runs on the PeopleSoft Enterprise PeopleTools three-tier architecture. Oracle Solaris Cluster orchestrates the startup, shutdown, and failover of the PeopleSoft Enterprise PeopleTools components. The following table lists the data services that protect PeopleSoft Enterprise PeopleTools components in an Oracle Solaris Cluster configuration.

Table 1 Protection of PeopleSoft Enterprise PeopleTools components

PeopleSoft Enterprise PeopleTools Component	Protected By
Database server	The data service for the database that you are using, for example: For the Oracle database, the data service is explained in the Oracle Solaris Cluster Data Service for Oracle Database Guide. For the Oracle RAC database, the data service is explained in the Oracle Solaris Cluster Data Service for Oracle Real Application Clusters Guide.
Application server	The data service is HA for PeopleSoft Application Server. The resource type is `ORCL.PeopleSoft_app_server`. The data service is explained in this document.
Web server	The data service is explained in the Oracle Solaris Cluster Data Service for Oracle WebLogic Server Guide.
Process Scheduler	The data service is HA for PeopleSoft Process Scheduler. The resource type is `ORCL.PeopleSoft_process_scheduler`. The data service is explained in this document.

HA for PeopleSoft Enterprise requires that a functioning cluster with the initial cluster framework is already installed. See the Oracle Solaris Cluster 4.3 Software Installation Guide for details on initial installation of clusters and data service software. You register HA for PeopleSoft Enterprise after you successfully install the basic components of Oracle Solaris Cluster and PeopleSoft Enterprise software.

For information about which version of PeopleSoft Enterprise software is compatible, see the Oracle Solaris Cluster Compatibility Guide available at the Oracle Solaris Cluster Technical Resources page.
