12 Challenges with the upgrade Online patching readiness report failed on many objects 12c database and Rapid Install StartCD 49/50 never worked Rapid Install StartCD 50 for EBS 12.2 comes with a database 12

13 Challenges with the upgrade Since Feb. 22, 2016, Rapid Install StartCD 51 is available. It comes with DB. You can download as Patch Different OS on DB/apps tier level Rapid Install is not user friendly Progress bar of the installer is not informative You have add ebs_patch to your service_names parameter db_domain parameter have to be set to null You have to resolve every issue detected by the installer RDA - Health Check / Validation Engine Guide (Doc ID ) 13

15 Challenges with the upgrade When Rapid Install performs the installation of the database software its cluster verification utility can result in an error on Oracle Linux / Red Hat Linux 6.3 or higher Workaround from Checks and Potential Issues Installing EBS R12.2 on RAC Cluster using Rapid Install (Doc ID ) mv /usr/sbin/nslookup /usr/sbin/nslookup.orig echo '#!/bin/bash /usr/sbin/nslookup.orig $* exit 0' > /usr/sbin/nslookup chmod a+x /usr/sbin/nslookup 15

16 Challenges with the upgrade Configuration issues with the apps tiers Missing rpms Kernel parameter changes Swap space was not set to 16 GB See Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.2) for Linux x86-64 (Doc ID ) 16

17 Challenges with the upgrade Cleaning Up A Failed Install Attempt There is no rapidwiz -restart option available with R12.2, you have to clean up the failed install manually a) Restart the server or make sure to kill ALL oracle and applmgr processes. b) Delete the install directory, orainventory and /tmp. c) Run rapidwiz to start installation again. (based on R12.2: How To Create the Stage In Preparation For Installation (Doc ID )) Vision Install s weblogic pwd was different from the one, that the doc. mentioned See page 3-36 within the Oracle E-Business Suite Setup Guide >> 17

18 Challenges with the upgrade AD_ZD_PREP is Invalid after R12.2 Upgrade Solution (based on Online Patch Enabling Patch Is Failing on ADZDPREP.sql (Doc ID )) 1. Check whether adgrants.sql is run. 2. Check whether all patches are applied as per below document along with post install steps: Database Preparation Guidelines for an E-Business Suite Release 12.2 Upgrade (Doc ID ) 3. GRANT SELECT, UPDATE, DELETE, INSERT on sys.xdb$moveschematab to apps; 4. Restart the worker. 18

19 Challenges with the upgrade Full Compliance vs Runtime Compliance Full Compliance Development meets all standards to support runtime and online patching operations Specialized deploy methodology to implement changes in the patch edition/file system o See Doc ID for all online patching compliance standards All Oracle ebusiness Suite products meet full compliance Runtime Compliance A subset of the full compliance standards that allow a product to operate correctly in R12.2 Customizations and thirdparty tools may only meet runtime compliance 19

20 Challenges with the upgrade A minimal set of standards must be followed for custom code All code must access the data model through the APPS synonym Table names must be unique at 29 bytes Column names must be 28 characters or fewer Column names must not use the # as the last character Third party products and integrations must be validated as well Online Patching Readiness Reports Online Patching Standards Checkers See EBS Developer's Guide Release 12.2, Chapter 7 for full standards list Planning and Preparing for Your Upgrade to Oracle E-Business Suite

22 Pre Upgrade Steps Run Online patching readiness report - available for all releases prior to These highlight all cases in Oracle E-Business Suite code or custom code where a non-editioned object references an editioned object. (See details at Oracle E-Business Suite Concepts Release 12.2 Part Number E ) Adopt the new 12.2 development standards Deploying Customizations in Oracle E-Business Suite Release 12.2 (Doc ID ) Upgrade to the latest supported database versions 11gR2: c: database Upgrade the Oracle Single Sign-On component to Oracle Access Manager (See details at Overview of Single Sign-On Integration Options for Oracle E-Business Suite (Doc ID )) Upgrade desktop OS to Win 7 or 8.1 ad browser to IE 11 Upgrade to the latest JAVA Move to FNDLOAD 22
