  3. Agenda • Available cloning methods • Differences between methods • Cloning Options available for each method • Advanced Rapid Clone Options • Future Cloning Options • Rapid Clone – Tips, tricks and lessons learned • Case Study - 11i Cloning at NIH • Custom cloning method • Automated third party tools

  4. How can I clone an Oracle Applications 11i System? • Available methods: • Cloning using AD Clone utility (adclone.pl) • Cloning using Rapid Clone • Custom cloning methods • Automated tools

  5. What are differences between available cloning methods? • Cloning using adclone.pl method • Applicable for all 11i releases up to 11.5.5 that are not AutoConfig enabled • adclone.pl method requires that you run Rapid Install and apply RDBMS and Technology Stack patches to target system • Cloning using Rapid Clone • Applicable for all 11i systems that have migrated to AutoConfig and enabled Rapid Clone

  6. Which cloning method is best for your environment? • The best method depends on: • Version of applications: • Prior to version 11.5.7 (adclone.pl) • Version 11.5.7 and higher (Rapid Clone) • Version of Database: • 8i (adclone.pl and Rapid Clone) • 9i (Rapid Clone only)

  7. Future Cloning Options • Fully automated RAC cloning with Rapid Clone (available now !!!!!) • Cloning using Oracle Maintenance Wizard version 1.10 and Applications Cloning Assistant for 11.5.10 (planned to be released this summer)

  9. Advanced Rapid Clone Options • Cloning a single-node to a multi-node system • Cloning a multi-node system to a multi-node system • Adding a new node to an existing system • Cloning “shared appl_top” • Cloning a multi-node to as single-node system • Follow the procedure for Merging Existing APPL_TOPs doc id: 233428.1 • Use Rapid Clone from OAM

  10. Rapid Clone • Advantages of Rapid Clone • All Tech stack is copied unlike adclone • Includes RDBMS, 8.0.6 and iAS • Exact copy of Source Environment • Able avoid re-applying tech stack patches • Create new environment without running Rapid Install • Disadvantage of Rapid Clone = Numerous Steps, not a single program

  11. Rapid Clone Tips - RMAN • ‘Cloning Oracle Applications Release 11i with Rapid Clone’ (doc # 230672.1) • Integration with RMAN: • ‘Copy database tier file system’ (Section 2-Step 2b) • Copy rman files, Delay $ORACLE_HOME copy • Use RMAN, ‘duplicate’ source DB • Pre-create ‘tempfile’ for TEMP tablespace • Shutdown Target DB after RMAN complete • Complete Step 2b, copy Source $ORACLE_HOME • ‘Configure target system database server’ (Section 2-Step 3a)

  12. Rapid Clone Tips - Patching • Rapid Clone and AutoConfig tightly coupled • Patches to either destabilize cloning • Retest Clone method after patches to either • Avoid patches to either unless time for testing • We did not patch either for 1 year after 11.5.8 upg • After patches to either, build new target context file • Do not reuse existing since usually new entries • Use ‘Port Pool’ logic when running adcfgclone.pl • RDBMS context file rebuilt with adbldxml.sh

  13. Rapid Clone Tips…. • RDBMS AutoConfig, Rapid Clone may/will clobber files • init_<sid>.ora, tnsnames.ora, sqlnet.ora • Avoid direct changes to AutoConfig generated files • Take advantage of ‘ifiles’, not clobbered • Give ‘ifiles’ meaningful names in RDBMS context file • init_<sid>_ifile.ora, tns_<sid>_ifile.ora

  14. Rapid Clone Tips… • Check log files (some not documented) • /tmp/adcfgclone*, $ORACLE_HOME/install/make*log • Unset environment before run adcfgclone.pl • Problems if point to Source by accident • Call <sid>_<box>.env instead of APPSORA.env • Reuse Target context file (except after some patches) • perl ./adcfgclone.pl dbTier <context filename> • perl ./adcfgclone.pl appsTier <context filename> • Develop detailed Rapid Clone cookbook

  15. Case Study – 11i Cloning at National Institutes of Health • Five year phased implementation • Multiple, nightly clones (approximately 100/year) • Automated/unattended – cron scripts • Releases 11.5.3 to 11.5.9 • Multiple servers, accounts, mountpoints, ports • Multiple database environments (Oracle/Gelco)

  16. Case Study – 11i Cloning at National Institutes of Health Environment Statistics • Oracle E-Business Suite Release 11i - Production • 550 Application Users • 200 Database Users • 225,000 Database Objects • Total Environment Size – 210 GB Disk Allocated, 179 GB Used • 125 GB Database • 30 GB Application Code • 9 GB Patches • Nine Production and Production Support Environments (Production, Quality, Test, Training, Development, Sandbox, Patch, Year-end, Upgrade) • Gelco Travel Manager 8.10 • 33,000 Traveler Users • 2,700 Application Users (Planners, Reviewers, Approvers, Administrators, System Administrators, Super Users) • 10 Database Users • 3,900 Database Objects • Total Environment Size – 30 GB Disk Allocated, 24 GB Used • 14 GB Database Size • 7 GB Application Code • Nine Production and Production Support Environments (Production, Quality, Test, Training, Development, Sandbox, Patch, Year-end, Upgrade) • Total Environment – Production, Development and Project Phases • 44 CPUs • 101 GB RAM • 10 TB Disk Space

  17. Case Study – 11i Cloning at National Institutes of Health • Weekly cold backup using gtar/compress to separate disk mountpoint – also used for disaster recovery • Untar cold backup of source environment into $ORACLE_BASE of target environment • gtar –zxvf <sid>_weekly_diskbackup.091304.gz • Supply source and target environment information • Hostname • SID • Starting port • Post clone tasks • Scramble privacy act data • Remove old directories • Implement customizations - WebADI • AutoConfig enabled but not executed during clone process up through 11.5.9

  22. Cloning Prod to Test Pre-clone steps Data transfer (Threaded) PROD TEST Post-clone steps Single click Scheduling request Reports Automatic Audit Trail Downtime, who, what, when?

  23. Benefits • Single click - Component complete • Reduce time spent on cloning • Clone more frequently • SOX compliant (audit trail, reports)
