Siebel CRM Applications on Oracle Ravello Cloud Service ORACLE WHITE PAPER AUGUST 2017
Oracle Ravello is an overlay cloud that enables enterprises to run their VMware and KVM applications with data-center-like (Layer 2) networking as-is on public cloud without any modifications. With Ravello, enterprises don t need to convert their VMs or change networking. This empowers the business to rapidly develop and deploy existing data-center applications on the public cloud without the associated infrastructure and migration cost and overhead for a variety of use-cases such as devtest, staging, UAT etc. Siebel CRM Overview Oracle's Siebel Customer Relationship Management (CRM), the world's most complete CRM solution, helps organizations achieve maximum top- and bottom-line growth and deliver great customer experiences across all channels, touchpoints, and devices. Siebel CRM delivers transactional, analytical, and engagement features to manage all customer-facing operations. With solutions tailored to more than 20 industries, Siebel CRM delivers comprehensive onpremise and on-demand CRM solutions that are tailored to industry requirements and offer role-based customer intelligence and prebuilt integrations. Siebel CRM core components Siebel CRM deployment consists of some core components, which are given below with the function they provide Component Siebel Gateway Name Server Siebel Server Siebel Web Server Extension Siebel Web Server Siebel Web Client Siebel Database Function Stores Siebel Enterprise Server and Siebel Server configuration and status information. Application server software that provides both user services and batch mode services to Siebel clients or other components. The SWSE identifies requests for Siebel data and forwards them to the Siebel Servers. It receives data from Siebel Servers and helps format it into Web pages for Siebel clients. Software installed on a third-party Web server computer, where the virtual directories for Siebel applications are created. The Siebel Web Client runs in a standard browser on the end user's client computer Stores database records 1 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
The following diagram illustrates the relationship between the elements of the Siebel CRM deployment. Fig. 1: Simplified Siebel CRM architecture Why run Siebel CRM on Oracle Ravello? Enterprises running Siebel CRM application in their data-center, typically need many copies of their environment for various purposes. Typically for every 1 production instance of the Siebel environment in their datacenter, enterprises have 5-8 copies of this environment for pre-production use-cases such as development, testing, staging and running User Acceptance Tests. However, most of the preproduction environments are not needed 24x7, but only for a few hours. For such ephemeral needs, it doesn t make economic sense to invest in a data-center based environment. Ravello provides a great platform for such use-cases that need ephemeral environments by offering data-center-like capabilities on public cloud (ability to run VMware VMs with Layer 2 networking). This helps enterprises reduce their infrastructure costs for such ephemeral workloads. As an example, an enterprise running one production instance and 5 pre-production environments of such a Siebel deployment on-prem can benefit from 58% savings by running compared to running onprem. 2 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Moving Siebel CRM application to Ravello A common scenario to deploy Siebel CRM on VMware ESXi on-prem in a multi-node setup is with 7 nodes housing Siebel components Siebel database, Siebel Gateway Name Server, Siebel Application Server, Siebel Web Server, Siebel Web Developer Client, Siebel File System and Siebel Web Client) one on each of the VMs. The deployment diagram for the implementation: Fig. 2: Deployment diagram In this on-prem deployment, we had Oracle Linux 7.3 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 - 10.0.0.0/24 - public network - 10.1.0.0/24 - application network 1) IMPORT: To build the Siebel CRM application with Ravello, we first import the 7 VMs that are setup in our on-prem ESX environment into Ravello s VM library using the Import Tool. 2) BUILD: Once imported, we can create a new application by dragging the VMs onto the canvas. 3 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Fig. 3: Building the application with the imported VMs 3) The system resources (vcpus, memory) allocated to each of the VMs was automatically preserved when imported into the Ravello VM library. On the network tab, Ravello automatically re-creates the network as it was setup in the data-center based on the meta-data associated and information parsed from the VM disk images.

We will now make sure all the settings in each VM are as per our expectation. Let us take a look at Gateway VM in the Ravello UI. 4) Let us start with the General tab. Make sure that the hostname field is populated and it matches to the hostname in the VM. Fig. 5: General tab for db server 5) Under the Disks tab, Controller we select is the PVSCSI para-virtualized controller for better performance. 5 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Fig. 6: Disks tab for Gateway server 6) Under the NICs section, we select the VMXnet3 para-virtualized device for each of the NICs, for better performance. As pointed out earlier, we have used a separate subnet to handle application traffic for our Siebel app. We verify that all the NICs are present and configured correctly for each of the nodes with the right IP configuration. 7) We have enabled ssh service for the Gateway server so that we can access it from the internet, externally. Make sure the External checkbox is checked to allow this. 6 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Fig. 7: External services Next, we Edit and Verify all the VMs on the application in a similar fashion. Once this is done, the application is ready to be published. 8) DEPLOY: Publish the application to bring up the VMs in the public cloud either using Costoptimized or Performance-optimized selection. Starting up the Siebel CRM Application The Siebel application requires the following sequence in starting the different components of application servers to access the application Database server à Gateway server à Application server à Web server Ravello provides this functionality to start your application in a sequence by providing the information in the VMs start order in the settings tab. Follow the steps to set up the sequence for Siebel application startup. 1) Select the Siebel application and click on Settings then click on + Add Stage in the VMs Start Order section. 7 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Fig. 8: VMs Start Order 2) Provide the stage name and time to schedule the start up for next stage Fig. 9: Create New Stage 3) Click on the VMs List and select the VMs to be added to the stage 8 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Fig. 10: Add the VMs to the created stage 4) Build all the stages to get the complete setup as follows: Stage 1: Storage: VMs: Siebel_DB and Siebel_filesys Stage 2: Logic_GW: VMs: Siebel_Gateway Stage 3: Logic_App: VMs: Siebel_AppServer and Siebel_WebServer Stage 4: Application: VMs: Siebel_Tools and Siebel_WebClient Fig. 11: Complete stage setup 9 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
Verifying the Siebel CRM application running on Ravello 1) Start the Siebel application from the Ravello UI to boot the VMs in the order specified Fig. 12: Start the Siebel CRM Application 2) Confirming that Siebel database and listener service is up and running on the Siebel_DB VM Fig. 13: Database and listener status 3) Check connectivity from the Siebel server using srvrmgr utility Fig. 14: Siebel server verification 10 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
4) Test connectivity to the Siebel Web Server from your browser. The IP address for the Web Server should be shown in Summary tab for the VM Fig 15: Public IP of Siebel WebServer Fig. 16: Application login For this Siebel CRM deployment, we enabled the Call Center component, for which is connectivity is shown above using the public IP assigned to the VM. 11 SIEBEL CRM ON ORACLE RAVELLO CLOUD SERVICE
