6 Review Customer Environment and Challenges for Upgrade

7 Environment Information EBS Environment Information: Oracle EBS Suite Oracle Database Windows bit EE SP2 Oracle running on VMWare Modules ( AR,AP,GL, and PO ) DB Size less than 500GB Customizations # of Custom Schemas 2 # of Custom Objects 5940 # of Custom Interfaces 2 # of Custom Forms 193 # of Custom Reports 107

8 Environment Challenges Oracle EBS Database and Application not patched Oracle Application tools adpatch, adrelink and adadmin fails with runtime errors Multiple Oracle Support request running more than 8-9 months Customer s Internal Team tried to Upgrade which failed twice Oracle Database inventory missing for patching Oracle Database and Application migrated as part of Hardware Refresh over 10-years Database and Application stopped daily for cold backup and Instance refresh Oracle APPS password shared with Business Users to Run Discoverer Reports

9 Project Timeline and Milestones

10 Project Major Milestones

11 Oracle EBS R on 12c Database within 7 Months

12 Oracle OVM Migration and Options

13 Oracle EBS VMware Setup

14 Oracle OVM Using Existing Hardware

15 Migration to Oracle OVM

16 Oracle EBS Migration Path from 11i to R12.2 on Linux Database Upgrade from 9i to 10g on Windows Environment Apply AD.I.7 Patch to Windows environment OS Pre-requisites for Release /R and Database 11g/12c Release Installation Platform Migration Export/Import to Linux Upgrade to Release and OATM Conversion Release Installation Upgrading to Release Enable Oracle E-Business Suite Online Patching Techstack Patching and EBS Upgrade Upgrade JRE to 1.7.0_025 Database upgrade from 11g to 12c ( )

17 Options Explored to Apply AD.I.7 Patch for Upgrade Option 1: Working with Oracle Support Option 2: Fresh Install on New VM Tried to follow up and push oracle support to involve Oracle Development. Started troubleshooting and reverse engineering base on error message. Begin to tweak standard EBS admin tools adadmin, adrelink to push the patch. In 2 weeks came to deadlock position. Installed fresh install on new Windows 2003 VM. Reconfigured New EBS to customer Oracle Database instance. Admin tool adadmin and adpatch worked well. Even applied prerequisite AD patches. Mandatory AD.I.7 patch got stuck and started crashing adpatch. Came to a stop by 3 weeks.

18 Mandatory AD.I.7 Patch for Upgrade DBA s What Next?

19 Applied AD.I.7 Patch Option that worked: Installed Fresh Linux OEL 4 Applied delta patches Pointed Oracle EBS Suite to Oracle Database on Windows Validated and Performed adadmin, adrecompile etc. Applied AD.I.7 prerequisite and Mandatory patches with safe Ignorable errors. Turned on Multi-Org Now DBA s all set to Kick-Start the Migration In six weeks had a working Solution for Migration.

20 Oracle Upgrade Pre-Downtime Activity Pre-requisites Check For Database and EBS installation Installed Oracle Database 10g, 11g and 12c on OEL 6 Fresh installation of R and R Fresh Installation on OEL4 to apply AD.I.7 Patch Install base software and update 10g Companion CD Perform patch set installation tasks Apply Windows patch 1 - Patch (32-bit) Windows patch. Create nls/data/9idata directory and Apply Shut down Applications server processes and database listener on Window

21 Oracle Database Upgrade from 9i to 10g Shutdown Application and Database listener service on Window Run pre-upgrade tool Resolve any outstanding unresolved distributed transactions Disable all batch and scheduled jobs Ensure SYS/SYSTEM have default tablespace Drop XDB.MIGR9202STATUS before upgrading the database (to avoid the issue described in Note: ) Validate if XDB Install Triggers exists Delete your services with the ORADIM of your 9i Oracle Home Copy password file to the New Oracle Database 10gR2 Home Set the new ORACLE_HOME in oratab and disable automatic startup

22 Oracle Database Upgrade from 9i to 10g(Contd) Startup upgrade from 10g Oracle Home Run catupgrade.sql Validate Upgrade and Restart the Database Re-create DML triggers on tables with Oracle Label Security policies Run utlrp.sql to recompile any remaining stored PL/SQL and Java code Restart Database service after upgrade Perform post steps of patch and Install Oracle Data Mining and OLAP component Execute adgrants.sql Grant create procedure privilege on CTXSYS Modify listener.ora file and restart listener from Oracle Home Gather SYS statistics

23 Point to Windows 10g Database and Apply Pre 11i Patches Point installed on OEL4 to 10g Database on Windows Replace following parameter in.xml to point to 10g Database on Windows server <TIER_DB oa_var="s_isdb">no</tier_db> <dbhost oa_var="s_dbhost">dbhostonwindows</dbhost> Run autoconfig on Application server Apply AD.I.7 Patch and EBS Export/Import Patch Validate and Convert to Multi Org (Conditional) Apply Oracle Applications Technology Family Pack 11i.ATG_PF.H Pre-requisites Patches: , , , , , , , Apply u drv plus u drv (Oracle Applications Technology Updates for 11i.ATG_PF.H.delta.6 ) Post ATG patch: RELEASE PRODUCTS NAME PATCH

24 Platform Migration from Windows 10g to 11g on OEL6 Source 10g DB on Windows Generate target database instance creation script adcrdb.sql Record Advanced Queue settings Remove rebuild index parameter in spatial indexes Synchronize Text indexes Create the export parameter file Grant privilege to source system schema Post Patch steps for Drop custom views (markview tables ) To save time with OATM Export the Applications database instance

25 Platform Migration from Windows 10g to 11g on OEL6 (Contd) Create 11g target shell database Install Java Virtual Machine and other required components using aumsc1120.sql Verify DB components on Source and Target from dba_registry Import application database Reset Advanced Queues Perform 11g Post Patching Steps Run adgrants.sql from R12 Grant create procedure privilege on CTXSYS Gather statistics for SYS schema Compile invalid objects using utlrp.sql

26 Oracle OATM Conversion Validate and Convert to Multi Org Drop event alert triggers in custom schemas Re-direct Imported 11g Database to Installed R on OEL6 Review sizes of old and new tablespaces using $FND_TOP/bin/fndtsmig.pl Run AD preparation scripts using adgncons.sql from patch Modify DB parameters needed for OATM conversion Execute OATM conversion job Validate and perform post OATM Conversion task

27 Oracle EBS Upgrade to Release Gather schema statistics for CBO Drop MRC schema Ensure that Maintenance Mode is enabled Apply Pre-req patches Merge this patch ( :R12.AD.B) with :R12.AD.B and R12.AD.B.1(patch Pre-install patches for R12.1 upgrade Downloaded all the patches from note using wget.sh and applied in pre-install mode after merging all the patches Apply patch in pre-install mode Merge Main driver u drv cd $AU_TOP/patch/115/driver admrgpch -d. -preinstall -master u drv adpatch options=nocopyportion,nogenerateportion drive file u_merged.drv Compile flexfield data in AOL tables Recreate grants and synonyms for APPS schema Login to EBS R12.1 and Perform a quick health check

28 Oracle EBS Upgrade to Release Re-direct EBS 12.2 to 11g Database Pre-Upgrade Steps Oracle E-Business Suite Release Notes, Release 12.2 (Doc ID: ) Stop Application Service Update init parameter with upgrade parameters Database Initialization Parameters for Oracle Applications Release 12 (Doc ID: ) Set FAILED_LOGIN_ATTEMPTS to UNLIMITED for Oracle E-Business Suite schema Ensure at Maintenance Mode is enabled Apply AD 12.2 upgrade driver ( ) Apply the Consolidated Upgrade Patch (CUP) for Release Patch in pre-installation mode on the Run Edition Filesystem

29 Oracle EBS Upgrade to Release Enabling ADOP Patch : STANDALONE READINESS REPORT AND GLOBAL STANDARDS COMPLIANCE CHECKER (GSCC) Run the Readiness Report after the enablement patch completes: sqlplus sqlplus sqlplus TECHSTACK PATCHING RUN EBS TECHNOLOGY CODE LEVEL CHECKER (ETCC) Oracle form patches and RSF patches for Forms Oracle FMW Patches Consolidated Seed Upgrade Patch Apply the Latest AD and TXK Delta Release Update Packs Apply Oracle E-Business Suite Release Update Pack Patch Apply Online patch and FND patch Upgrade JRE to 1.7.0_02

30 Oracle Database Upgrade to 12c Gather Schema Statistics on SYSTEM schema Run Pre-upgrade script Install Oracle binaries including Examples v CD Additional RDBMS patches Create nls/data/9idata directory Complete the DB Upgrade using DBUA Post Upgrade Steps Update listener Home to 12c Run adgrants.sql Grant create procedure privilege on CTXSYS Compile invalid objects Set CTXSYS parameter Validate Workflow ruleset Deregister the current database server Implement and run AutoConfig Create the new MGDSYS schema Gather schema statistics on AD schema

31 Tips and Lessons Learned

32 Post Release Upgrade Tips fs_clone not Copying files from Run to Patch filesystem Specify the synchronization step in the custom sync up driver $APPL_TOP_NE/EBSapps/appl/ad/custom/adop_sync.drv. Add the actions within #Begin Customization and #End Customization section. The actions would be performed during ADOP synchronization phase. # Sample For Unix Platform rsync -zr %s_current_base%/ebsapps/appl/mbs/ %s_other_base%/ebsapps/appl/mbs rsync -zr %s_current_base%/ebsapps/comn/java/classes/atlhdc %s_other_base%/ebsapps/comn/java/classes rsync -zr %s_current_base%/ebsapps/comn/java/classes/mbs %s_other_base%/ebsapps/comn/java/classes Lower Case Custom files names were not Getting recognized on Release All the lower case names are extracted from 11i on windows source server to target OEL6 server during the custom top creation. As part of retrofitting, Oracle Development Team created new files with Upper case as per R12 requirement.

33 Post Release Upgrade Tips EBS Profile change RRA: Enabled --> Yes Concurrent:Report Copies --> from 1 to 0 SLA: Enable SRS Log/Output --> NO Users Password Lock Passwords upon change in Release is case-sensitive if Signon Password Case = SENSITIVE Sign on Password Case Profile Does Not Work (Doc ID ) NFS Option Used for Linux For NFS V3 Doc ID rw,nointr,bg,hard,timeo=600,wsize=65536,rsize=65536,nfsvers=3,tcp Oracle Linux Tips for EBS Install wget yum install oracle-rdbms-server-12cr1-preinstall el6.x86_64 yum install oracle-ebs-server-r12-preinstall el6.x86_64 ldconfig v
