Management Infrastructure Challenges Benefits Oracle 11i Applications with 48 Applications Server and DB Server maintain by HCL Onsite & Offshore team Upgrade of Application as well as database New Technology components are configured like Hardware Load Balancing, 48 Application Nodes, Mobile Applications Servers and Automatic memory tuning DR server maintain in different location and data synchronized online by every 15 minutes 24*7 Production Support and Minimum production down time for maintenance SUN OS Configuring 48 Application Nodes with single Database DBA Support Achievements Maintain common instance for application and other tools Completed the Database Upgrade activity with in a scheduled period HCL DBA team spread with 6 Onsite DBA’s and 4 offshore DBA Patches applied on Heterogeneous Network 65 databases are maintained by DBA team Hardware Load Balancer with 48 nodes were maintained 14 Oracle Enterprise Manager has been integrated with OEBS sign on, through which client can see all the patches applied on the system and can monitor Concurrent Manager Activities etc. Shared Appltop Load Balance – new Technology introduced where it reduces drastically the down time of Applications and Improve the Performance Case Study 6 – Leading Provider of Simulation Software & Services Infrastructure Challenges Benefits Oracle 11i Applications on Solaris Servers. Application Support being done HCL team Upgrade of following technology stacks in single downtime window Developer 6i Patch set Upgrade Application Technology Group Patch level change { 5 to 6} 9.2.0.7 to 11.1.0.7 upgrade JInitiator to SUN JRE Migration JDK upgrade Shared Appl_top migration Critical patches update HR Family Pack upgrade Vertex Tax Engine Upgrade Shared Appl_top along with Distributed Admin reduced the down time of Applications Several Application Technology Stack need to be upgraded Version of EBS to be maintained @ 11.5.1.0.2 Shared APPL_TOP also reduced the over-all disk requirements Distributed AD enabled better resource utilization Oracle’s recommended and supported Level of RDBMS, Java Plug-in with Oracle EBS Recommend patch-set level for Critical Patch Updates DBA Support Achievements Regular Support and Maintenance of Oracle EBS environments Completed the Database Upgrade activity with in a scheduled period Technical Upgrades Regular Patching and Cloning Reduced patching window because of shared Appl_top and distributed processing Support for Enhancements and Customizations Adherence to Oracle’s recommended patch set level 15 Case Study 7 – A Lifestyle Merchandising Company Operating Specialty Retail Stores Infrastructure Challenges Benefits Client is currently using db2 and mssql to maintain their enterprise information Testing of the upgrade required lot of coordination effort Scalable and high available environment for Production instance because of RAC Implementation The requirement was to migrate data from db2 and mssql to Oracle 11g database The requirement was also to implement 2-node RAC for new Oracle 11g database Setting up RAC cluster environment with Red Hat Linux and porting database into RAC environment Performance tuning of new Oracle Database when benchmarking from db2 could not be used directly Defining new administration procedure for RAC Database DBA Support Achievements RAC Implementation Completed the Database Upgrade activity with in a scheduled period Database Migration to 11g Performance tuning Post Production Support 16 Greater business productivity Costs reduction as Oracle Databases are created on Linux Platform Customer is better placed to plan and leverage the new features of 11g. Recommendations have been given to the customer on same Case Study 8 – Leading Automated Test Equipment Manufacturer in Semi-Conductor Infrastructure Challenges Benefits Client is currently using 150+ Oracle Databases and 50+ MSSql Databases to maintain their enterprise information Datawarehouse Upgrade Complex Upstream and Downstream applications. New DB Version integration incompatibility in certain old Legacy Upstream System Cannot afford longer downtime No Direct Upgrade Path to 8.1.x to 9.x Datawarehouse Applications and Database are compatible and in Supported Platform HCL is collaboratively running the clients IT Division and DBA services are part of this Multi-Service Delivery Engagement One of the requirement was to upgrade their Enterprise Datawarehouse Oracle Databases from 8.1.6 to 9.2.0.8 Another requirement was to upgrade their Parts and Drawing Application (SMARTEAM) database from 9.x to 10.2.x with Advanced 8 Site Multi-Master Replication SMARTEAM All sites have to be upgraded simultaneously Ensuring Multi-Master Replication is intact after Upgrade Achievements DB Upgrade with Planned minimum downtime, Multiple DBA’s were engaged for multi Database Upgrade 17 Customer is better placed to plan and leverage the new features of upgraded DB Versions Enabled Customer to save on 3rd Party utility licenses Enabled better customer satisfaction Client Appreciations… On Technical upgrade of EBS Environment… “ Thank you for your hard work during the upgrade. Overall, the process went extremely well and is a result of your dedication in both preparation and execution of this highly visible project…persistence and teamwork prevailed! I am especially pleased with the success of working with a 'remote' team. We were able to coordinate a smooth continuous schedule that contributed to achieving our goal without any major incident and ahead of schedule! Congratulations on a job well done! ” – Paula Hockster, IT Director {A leading provider of Simulation Software and related services.} On Migration of EBS Environment… “ The migration of our Conferencing Oracle Applications E-Business suite from a UK AIX/RS6000 infrastructure to a US LINUX/Intel based infrastructure posed a significant number of managerial, technical and logistical challenges. The three-man (HCL) Database Administration Team ably resolved all the challenges this major application migration posed them. The team utilized their technical skills, experience and applied their own original approach to resolve each of the challenges successfully and delivered the migration on time and on budget. ” – Andrew Gray, Globalization Programme/ Project Manager, RLT Member On RAC Implementation… “ I wanted to send you a quick email to say a big THANK YOU for all the work that you have been doing not just this past weekend, but throughout the globalization process. I really do appreciate the level of commitment and calibre that you bring to the team. – Global CIO ” 18 HCL’s Value Proposition Checklist based assessment Point out overlooked issues deep within your database environments that may be causing poor performance/ slowing down your operations. Database administration is not restricted to Core Database infrastructure alone, but spans across the application landscape as well, giving you a robust support framework. Increased Availability Take advantage of our DBA maintenance services and decrease the chance of sudden failure. Our team pro-actively monitors problem areas and fixes them before they can cause havoc due to instance down times/ systems crash. Regular MIS reports and Dashboard generated tracks; evaluation of application and database performance and growth, with pro-active steps taken to mitigate risk and improve system up-time. Flexibility Application Practice Improved Performance & Risk Mgmt. With requirements on DB management increasing by the day, HCL’s strong skill-base of experts give you the flexibility to find the right resource with the right knowledge to augment your team during project crunches. 19 Next Steps… 20
