18 months old implementation of E-Business Suite 11i
Oracle Applications 11.5.10.2 running on 9.2.0.6 database
Two node architecture with database on one node and all the application services on another node
Intended to be 9i RAC on OCFS but 2nd RAC Node never worked due to OCFS issues hence being used as a single instance
Upgrading from 9.2.0.6 to 10.2.0.4 in a High Availability RAC Architecture on RHAS 5.1
Oracle Database migration from 32-bit Linux server to new 64-bit Linux server with 64-bit O/S

13
Case Study 4 – Largest Provider of Conferencing Services in Europe
ChallengesDatabase Upgrade Benefits
Implemented a system with a centralized repository, hardware, and a common interface for the client’s business across the globe, which resulted in further reduction of their TCO and maintenance
The new enhanced features of 10g like Merge & Schedulers were used to restructure the application, which helped in reducing the time of Data Warehouse loads by 50% and helped manage it more efficiently
Building the RAC Database
TAF Configuration
Deploying the Application to the RAC environment
TAF Testing, and
Structured Testing & Tuning
Migrated terabytes of data from the 9i database to the new 10g database RAC
Added 6 Node Cluster for performance
Platforms migrated from AIX 4.3.3 to Linux 3.0 ES
Platforms migrated from UK DWHS 9i RAC to US Global DWHS 10g RAC Rel 2
The company’s globalization project demanded a common Business Intelligence system across the globe which would provide them a single storage location of all their business data with maximum performance benefits and high availability
The existing 9i RAC nodes were serving only users based in UK and was fast becoming outdated as the business demanded more advanced features

On Technical upgrade of EBS Environment…On Technical upgrade 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.
