Oracle Application Server 10g (9.0.4)Recommended TopologiesPavana Jain
Agenda • Topology Considerations • Recommended Topologies • Q and A
Recommended Topologies • What is it? • Oracle Recommended Topologies • To address 80% use cases in the market • Why do we need it? • Too many deployment topologies • Test, document, support and recommend smaller set of topologies • What are the benefits? • Oracle • Enables better planning internally • Help guide customers on how best to deploy our product • Customers • Oracle recommended topology • Better performance
Recommended Topologies • General Development Configurations • Java Developer • Portal and Wireless Developer • Forms and Reports Developer • Integration Architect and Process Modeler • General Deployment Configurations • Enterprise Data Center Configuration • Departmental Configuration • Development Life Cycle Support Configuration (Test to Stage to Production rollout support)
Topology Considerations • Installation Considerations • How do I install Oracle Application Server 10G (9.0.4) to get to a specific topology? • Which distributed install model is best suited for this topology? • What types of machines are typically used in this topology? • What is the profile of the user who would do the installations in this topology?
Topology Considerations • Application Deployment and Performance Considerations • What type of performance goals are typical for this type of topology, and what heuristics can be used to estimate representative values for those goals. • What distribution of components across multiple hardware best meets those performance goals • How are applications and OracleAS components best distributed among multiple hardware nodes to meet the performance goals • What application development strategies will maximize the performance of a topology • What tunable parameters exist to improve performance, and how to determine when to alter these parameters
Topology Considerations • Security Considerations • What level of security does the topology require? • What isolation of components or applications is needed to increase the security of these topologies? • What 3rd party suppliers for security hardware and software requirements exist for these topologies?
Topology Considerations • Management Considerations • What facilities are required to manage this topology? • What distributions of components or applications across multiple hardware nodes provides for manageable topology? • What backup and recovery methods to use for these topologies? • What are the best management practices for these topologies?
Topology Considerations • HA Considerations • Which HA methodology is recommended for these topologies? • 3rd Party Products • What are the special 3rd party products such as gateways, adapters, and load balancer, firewall requirements in these topologies? • How do these 3rd party products impact the high availability, management, security and performance recommendations for these configurations? • Migration Objectives • How would earlier versions of Oracle9iAS need to be migrated to fit into this configuration?

Development Life Cycle Support Configurations
Development Life Cycle Support Configurations Tests ongoing. Recommendations not yet defined for how applications get moved from Test to Stage to Production Environment. . The instances do not move.. Just applications moves . Test environment recommendation would be similar to Developer topologies . Staging environment recommendation would be similar to Departmental topology . Production environment recommendation would be similar to Enterprise Data Center topology
Recommended Topology Project • Where are we with this project as of 8/7/2003: • Testing for deployment topologies are ongoing. Results with recommendation will be documented in official documentation before production. • Sizing tools are planned and we hope to have it delivered close to production. • The following sales tools are planned: • Cheat sheet with consideration decisions to help decide which topology a customer would get most benefit from . • Comparison study on how we compare with BEA/IBM wrt these topologies. • Document of the type of licenses recommended to deploy these topologies
