Planning Systems • Challenges –
– Growing data volumes – Increased need for near-real time responsiveness – Ability to simulate changing business models – Adapt to the competitive and customer landscape
• Goal – – Ability to plan the complex value chains faster & more
frequently; to greater level of detail, to make better decisions
Planning solution must meet the highest standards of mission critical enterprise systems in terms of availability, performance, scalability, and security

R12.2 Upgrade Approach
• R12.2 Upgrade was combined with Platform Migration to Engineered Systems – Exadata & Exalogic
• Customization was re-written to align with new approach
• Upgrade (R12.2) & Migration (Exa Stack) performed in one cutover window
• Database migrated from Exadata X2 to Exadata X4 • AppsTier migrated from Commodity H/W to Virtualized
Exalogic X3
• Upgraded to R12.2.3 for one region in 2014

Issues Faced • Online Patching enablement issues • Autoconfig failing on 12.2.3 instance • Issues with patches for upgrade and one-off fixes • Disable editioning on MSDEM schema in the VCP instance • Error when trying to configure second app tier for 12.2.3 • Patching using adop on remote node fails • After the clone, adstpall fails and then adstrtal cannot be
used to startup the services • When attempting to clone patch filesystem, rapidclone fails • After upgrade the EBS environment to 12.2.3, the login page
personalization does not taking affect • adcfgclone fails while cloning when source and target
instances are on the same servers

Lessons Learned / Takeaways
• Lack of Database Editioning for Demantra Schema
• Clone issues with R12.2 (WebLogic stack)
• Lack of R12.2 experience in Oracle Support team (Product team helped with lot of things)
• R12.2 Upgrade patches were constantly changing
• Lack of guidelines for developers for VCP customization; a white paper would be nice
• Demantra – Icon issue with Export/Import, Dem. AnyWhere
• Give yourself reasonable time while up taking R12.2 Upgrade
