VCP R12.2 Upgrade

Drivers for R12.2 •  Strategy to minimize maintenance downtime;

Leverage R12.2 Online Patching

•  RPC 1 on ERP environment for Manufacturing & WMS, warrants VCP(Demantra) to be upgraded to 7.3.1.5 or R12.2

•  Performance Improvements in R12.2

•  Getting to R12.2 enable to utilize new features – –  Calendar Month in Weekly Systems –  Import from File –  Multi-Language Support - Demantra –  Demantra AnyWhere Improvements – Embedded

29

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

30

Upgrade Benefits

•  Import/Export from Excel to Demantra

–  Assists with new product introduction

•  Performance Improvements –

–  Collection, Engine Run and Worksheets

•  Demantra Anywhere

–  Allows sales force visibility to forecast / objectives

•  Multi-Language Support for Demantra

•  Sales Calendar

–  Moved to monthly buckets – Earlier ; Plan is to move to weekly

•  End User Experience - Performance

31

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

32

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
