Local Touch – Global Reach

The Situation

Sogeti uses Oracle e-Business Suite to support its end-to-end business processes, including financials, human resources, project resource management, and project accounting.

Key statistics:

• Existing Application: EBS 11.5.10.2• Existing Database: 10gR2, Solaris 10 SPARC• Number of users: 3000• Modules Implemented:

• Financials (Accounts Payable, Accounts Receivable, General Ledger, Purchasing)

• Human Resources

• Project Accounting (Project Resource Management, iExpenses, Time & Labor)

• Fixed Assets

• Other Applications (outside of EBS): Several legacy applications, CRM, and Payroll

Challenge:

• A small IT team trying to meet the fast growing need of data

• A significant amount of time spent fighting fires, running ad-hoc queries against large data sets and optimize queries which have short shelf life

• Time lost due to performance issues with ad-hoc queries & reports

The Considerations

The key considerations in the decision

making process included:

• Time spent by IT team in developing and

supporting custom code needed to support

growing data needs of business users &

multiple database instances (estimated effort

reduction of 2 full time equivalents)

• Time spent by end users during the period of

system unavailability (estimated savings of 1

full time equivalent)

• Infrastructure cost avoided by consolidating

multiple database instances

• Time spent by end users while dealing with

performance challenges (estimated savings of

½ full time equivalent)

(Compared NPV of investments and cost savings,

assuming 5 Year Life for hardware and 10 year life for

software with no inflation and 11% weighted average

cost of capital)

5 Year expected ROI(NPV with 11% WACC)

Note: Does not account for fringe benefits resulting from improved and real-time visibility into KPIs/ financial

data, reduced lead times (resulting in faster cash collection)

The Decision

Based on anticipated savings and additional benefits, we decided to migrate our EBS 11.5.10.2

environment to Oracle Database Machine. Oracle Exadata will help:

Improve Consolidation

• Reduce number of instances by aggregating all Oracle database instances into a single instance

• Reduce effort needed to administer & optimize databases

• Reduce weekly tape backup from 4 hours to daily 4 minutes

Reduce Overall Costs/ Increase Productivity

• Reduce number of servers and simplify software licensing resulting in meaningful cost savings

• Reduce dependence on IT staff

• Increase availability resulting in significant productivity enhancements

• Enhance performance resulting in additional productivity

Enhance Reporting

• Eliminate batch processing for 20-25 nightly and weekly custom reports/ batch jobs

• Provide real-time reporting for critical key performance indicators

• Create a high-performing platform for subsequent BI/ DW implementation

The Unexpected

Issues Resolution

Failed flash drive • Service request filed; Sun engineer arrived onsite and replaced it within a day

Two cluster crashes • Applied latest patches to avoid bugs that were fixed in the most recent patch

set available at the time

Patch conflict between Oracle

Exadata BP3 and Oracle e-

Business Suite

• The conflicting EBS patches were incorporated into the subsequent Exadata

patch bundles

OEM DB Console did not work after

migration

• Created work around with few parameter changes

• Abandoned OEM DB Console in favor of OEM Grid Control

EM crashed when changing

resource plan

• Known issue that will be resolved in soon to be released BP6

Error in PO approval process in

Workflow

• Resolved with a Profile Option change

Failover not happening for

concurrent manager services when

Node 1 of RAC is down

• Created a work around by restarting concurrent manager when a DB instance

fails

Issues with NTP server

synchronization

• Resolved by reconfiguring NTP to use a relay server. Root cause has something to

do with using a Windows NTP server and Linux ntpd not able to sync with it.
