Agenda• Available cloning methods• Differences between methods• Cloning Options available for each method• Introduction to 11i cloning• 11i Cloning at Chicago Public Schools• Custom “F.A.S.T” Method• Questions
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 such as F.A.S.T
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
What are differences between available cloning methods?
• Cloning using Rapid Clone– Applicable for all 11i systems that have
migrated to AutoConfig and enabled Rapid Clone
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)
What cloning options are available for each method?
Single-node to Single-node
Multi-node to Multi-node
Single-node to Multi-node
Multi-node to Single-node
Cloning 11i apps using adclone.pl

Cloning 11i apps using Rapid Clone
Supported Supported Supported Not Available
Cloning 11i• More than one method….
– Ad Clone
– Rapid Clone
– Custom methods (F.A.S.T etc)
– 11.5.9 Enhancements (Application Manager console)
• With same end goal(s)– Create copies of environments
– To support DEV/QA/Test/Training activity
– Create separate “sandboxes”
Cloning 11i in a nutshell
• Why is Cloning 11i different….– 11i Architecture
– Two distinct application delivery methods
– Forms (Applets) and HTML/JSP
– Application Technology Stack different from earlier releases
11i Technology Stack Java Compatible Web Browser
(Jinitiator)
Database
(8i/9i)
Forms Server Reports Server
ConcurrentProcessing Server
Administrative Server
Discoverer Server
Web Server
Desktop Tier
Application Server Tier
Database Tier
Cloning 11i in a nutshell • The Process….
– Create a system map of “From” and “To”
– Document your source and targets (file systems, paths, port numbers)
– Copy Applications and Database Tiers (binaries and files)
– Clone the database instance and rename it.
– Update key Application related Database Profile tables
– Edit key Configuration and Environment files on the related nodes
Cloning 11i in a nutshell
• The Process….– Relink Applications Programs on related nodes (not
always needed)
– Create a new banner (logo.gif, if applicable)
– Regenerate Java Archive Files (JAR Files) (not always needed)
CPS Environment• Oracle Applications 11.5.8
– Multi-Node HPUX 11.11– 9.2.0.4 Database– EMC 8830 Symmetrix
• Recently Migrated from 11.0.3/8.0.5– First to 11.5.7 on 8.1.7– Then 11.5.8. on 8.1.7– Currently 11.5.8 on 9.2.0.4
RapidClone in Action at CPS• Sync/Split a BCV
– BCV Set includes full App Tier and DB Tier file systems• Mount BCV to Development Hardware• Change Directory Names, Owners, Perms• Modify the DB tier Oracle_Home
– Oracle_Home Edits• <sid>.env• Tnsnames, Listener.ora• Nmliblist
– Relink Oracle_Home• Recover Database• Modify the DB tier and APP tier 8.0.6_Homes
– 8.0.6_Home Edits• <sid>.env• Tnsnames.ora• Rdbms/lb/nmliblist
– Make –f ins_rdbms.mk install – Make –f ins_network.mk install
RapidClone in Action at CPS
• Modify the DB tier and APPS tier Appl_Top– Appl_top Edits
• Apps<sid>.env• Custom<sid>.env• Adovars.env• <sid>.xml
– Run $COMN_TOP/editcontext/editcontext– Run $AD_TOP/bin/adconfig.sh– Edit IAS_Home/Apache/Apache/bin/appachectl
• Startup the App Tier First – Modify your Profile Options.– Cancel Pending Conc. Reqs.
F.A.S.T Cloning• The Method
– Identify the data you need to change and list that in a file,<old><new> value pair
– Get the directories where changes will be imposed into a file
– Run the perl script to make changes automatically under those directories using <old><new> value pair
F.A.S.T Cloning• Script new structure creation
– Create new Directories ( APPL_TOP, 806, iAS, 8i home) (scripted)
– Create database using RMAN duplication (scripted)
– Run the perl script to make changes– Run $COMMON_TOP/admin/install scripts to
change the database information
F.A.S.T Cloning• Example Snippets ( sun solaris )
– Create new Directories tar cf - . | compress -c | rsh ora3800 "(cd
/u01/app/oracle/product; uncompress -c | tar xf -)“
- create a file with dir list- loc1=/u017/app/oracle/admin/ows/PSGOLD/httpd_apps280- loc2=/u017/app/oracle/product/PSGOLD816/Apache/
Apache- loc3=/u017/app/oracle/product/PSGOLD816/Apache/Jserv
F.A.S.T Cloning• Advantages
– Setup once for a given Source-Target instance pair– Fully automated into touch button cloning– Works on all releases 10.7 NCA, 1103, 11.5.X – Used at 20 clients or so personally
• Disadvantages– Not for junior DBA– Not oracle supported
