Active Data Guard for database HA/DR, multi-instance PIA behind Load Balancer, Process Scheduler on multiple nodes for batch processing resilience. ## Architecture (fetched from source) Architecture The following architecture diagrams show PeopleSoft and Oracle Maximum Availability Architecture (Oracle MAA). PeopleSoft Maximum Availability Architecture is a PeopleSoft high availability architecture layered on top of the Oracle Database and Oracle Fusion Middleware Oracle MAA, including a secondary site to provide business continuity in the event of a primary site failure. The following shows a full-stack Oracle MAA architecture, including primary and secondary sites. The secondary site is a replica of the primary. Description of the illustration peoplesoft-maa-arch.png peoplesoft-maa-arch-oracle.zip Each site consists of the following: - An HTTPS load balancer for web-based application services - Two servers that host the PeopleSoft Pure Internet Architecture (PIA) domain - Two servers that host both the PeopleSoft Application Server and the Process Scheduler domains - A shared file system for PeopleSoft application software and report repository - An Oracle Real Application Clusters (Oracle RAC) database, with two database servers and shared storage - Oracle Active Data Guard , which allows routing of “mostly read operations” to the standby database while keeping the standby database current with the primary Both the application tier shared file system and the database are replicated to the secondary site – the application tier using rsync, and the database tier using Oracle Data Guard . The data at the second site is kept in sync with the primary by using appropriate replication mechanisms. - For the database itself, Oracle Active Data Guard ensures the standby database is kept in sync and transactionally consistent. - For file system output generated during the operation of the application, rsync is used to frequently replicate the output to another region. There will be a small gap to resolve by identifying missing file system components and determining the action to take for each.
