PeopleSoft on Oracle Ravello Cloud Service ORACLE WHITE PAPER AUGUST 2017
Oracle Ravello Cloud Service Oracle Ravello is an overlay cloud that enables enterprises to run their VMware and KVM applications, including complex Layer 2 networking, on a public cloud without making any modifications. With Ravello, enterprises do not need to modify their VMs or change networking. This empowers businesses to rapidly deploy existing data-center applications to the public cloud without any associated infrastructure costs, migration costs, and overhead for a variety of use-cases such as devtest, staging, UAT, etc. PeopleSoft Application on Oracle Ravello PeopleSoft Overview Oracle's PeopleSoft applications are designed to address the most complex business requirements. They provide comprehensive business and industry solutions, enabling organizations to increase productivity, accelerate business performance, and a lower cost of ownership. PeopleSoft Enterprise Solution consists of several core components which are required for functioning of PeopleSoft. All these core components are interconnected and send/receive data and information required for processing of business needs. The PeopleSoft Internet Architecture is comprised of these main server types: RDBMS. PeopleSoft Application Server(s). PeopleSoft Process Scheduler(s). Web server(s). The following diagram illustrates the relationship between the elements of the PeopleSoft Internet Architecture. 1 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE

The database system tables manage both the PeopleTools and PeopleSoft application database objects, while the PeopleSoft application tables reside within the infrastructure defined by the PeopleTools metadata. Application Server The application server handles the bulk of the workload within the PeopleSoft system. It runs the business logic and processes all application requests. The application server relies on Oracle Tuxedo middleware to process transaction requests. Oracle Jolt provides the Java interface making Oracle Tuxedo available for web-based requests. Process Scheduler Web Server/Pia Server Process Scheduler has several components that work together to help you run reports and processes offline. After a job has been submitted, use Process Monitor to check the status of the job, and then use Report Manager to view the output of the job through a web browser. Process Scheduler Manager involves the interaction of these components, which you can select from the menu. The web server receives application requests from the web environment (internet and intranet) and forwards the requests to the Oracle Jolt port on the 2 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE
application server. A collection of PeopleSoft servlets running on the web server handle incoming requests. Like the server processes on the application server, each PeopleSoft servlet is designed to perform unique functions. For example, the portal servlet handles browser requests while the gateway servlet handles service oriented architecture (SOA) messages and requests. Why run PeopleSoft on Oracle Ravello? Enterprises running the PeopleSoft application in their data-center, usually need many copies of their environment for various purposes. Typically for every production instance of the PeopleSoft environment in their data-center, enterprises have 5 to 8 instantiations of this environment for preproduction use-cases such as development, testing, staging, and running User Acceptance Tests. However, most of the pre-production environments are live only for a few hours a day and are not needed 24x7. For such ephemeral needs, it doesn t make economic sense to invest in underutilized data-centers. Ravello is an ideal platform for use-cases with ephemeral needs. It offers data-center-like capabilities such as the ability to run VMware and KVM virtual machines with Layer 2 networking on public clouds. Such dynamic provisioning helps enterprises reduce their infrastructure costs for their ephemeral workloads. For example, an enterprise running one production instance and 5 pre-production environments of an Oracle PeopleSoft deployment on-prem can achieve 63% savings by running on Oracle Ravello compared to on-prem. Moving PeopleSoft Application to Oracle Ravello A common scenario to deploy Oracle PeopleSoft on VMware ESXi on-prem in a multi- node setup is with 4 nodes housing PeopleSoft components database, application, process scheduler and pia server / Web Server one on each of the VMs. The deployment diagram for the implementation shown below: In this on-prem deployment, we had Oracle Linux 7.1 running on ESXi VMs with the following topology. Each of the VMs was configured with 4vCPU and 8GB RAM with two different network subnets configured - 192.168.56.0/24 - public network - 192.168.1.0/24 - application network 3 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE

Figure 3. Building the application with imported VMs. 4 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE
a. The system resources such as the number vcpus and memory of each VM is preserved when they are imported into the Ravello library. Ravello also parses the metadata associated with the ESXi VM disk images and automatically recreates the network as it was set up in the data-center. Figure 4. Network view of the application. b. Next we will verify the settings in each VM, starting with the db-server VM in Ravello. We make sure that the hostname field is populated and it matches the hostname in the VM. Figure 5. General tab view of the db-server. c. Under the Disks tab, we select the para-virtualized controller, PVSCSI, for optimal performance. 5 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE
Figure 6. The Disks tab view of the db-server. d. In the NICs tab, we select the VMXnet3 para-virtualized device for each of the NICs. This leads to better performance. Figure 7. Network interface of the database server. e. We have enabled HTTP service for the app server on port 8000 so that we can access the app from the internet. Make sure the External checkbox is checked. 6 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE
Figure 8. External services. f. We follow a similar verification process for each of the other VMs in the application. Once completed, the application is ready to be published on to the public cloud. 3) DEPLOY: Click Publish to deploy the application in the public cloud by selecting either the Cost-optimized or Performance-optimized option. 7 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE
Starting and running the PeopleSoft Application on Ravello The PeopleSoft application requires the following sequence in starting the different components of the Peoplesoft application (database server à application server à process scheduler à pia server/web server) in an order, to access the PeopleSoft application. Ravello provides the functionality to start the PeopleSoft application in a sequence by providing the information in the VMs start order in the setting tab. Follow the steps to set up the sequence for PeopleSoft application startup. 1. Select the PeopleSoft application and click on settings then click on +Add Stage. Figure 9. Create VMs start and stop order. 8 PEOPLESOFT ON ORACLE RAVELLO CLOUD SERVICE
