Agenda

• Available cloning methods
• Differences between cloning methods
• Cloning using Rapid Clone method
• Cloning options available for each method
• Cloning methods best for your environment

3
How can I clone an Oracle Applications 11i System?

• What is cloning?
• Available methods
• Cloning using AD clone utility (adclone.pl)
• Cloning using AutoConfig on Windows
• Cloning using Rapid Clone (only available on Unix
  platforms)

4
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
• Cloning using AutoConfig
• Applicable for all AutoConfig-enabled 11i systems
  on the Windows platform
• Releases 11.5.7 and 11.5.8 are AutoConfig enabled
  out of the box
• Cloning using Rapid Clone
• Applicable for all 11i systems that have migrated
  to AutoConfig and enabled Rapid Clone

5
What are differences between available cloning
methods?

• adclone.pl method requires that you run Rapid
  Install and apply RDBMS and Technology Stack
  patches to target system
• AutoConfig requires that you run 11.5.7 Rapid
  Install to build installer inventory if you plan
  to patch target RDBMS home
• Rapid Clone does not require that you run Rapid
  Install nor build OUI inventory files

6
Cloning Oracle Applications using Rapid Clone
method

• Target system the newly created system
• Source system the system to be cloned
• Not yet supported on Windows platform
• Could clone OS binary compatible systems (HP UX
  11 and HP UX 11i Solaris 2.6 and Solaris 8)
• Pre-release 11.5.8 systems can be configured to
  use Rapid Clone
• If you have more than 4 mount points for the
  datafies, apply patch 2741120

7
Cloning Oracle Applications using Rapid Clone
method

• Standard Rapid Clone Method (single-node to
  single-node)
• Prepare the source system for Rapid Clone
• Stage the source system
• Copy the source system
• Configure the target system
• Perform post-cloning tasks

8
Prepare the Source System for Rapid Clone

• Migrate to AutoConfig (Note 165195.1)
• Apply prerequisite patches
• Apply the Context Creation and Editor patch
  2716534
• Apply patch 2614231 (OUI 2.1.0.17.0 used to
  register RDBMS and iAS homes)
• Apply AutoConfig consolidated update patch
  2716712
• Upgrade to JDK 1.3.1
• Generate applications context file (.xml)
  using Context Creation Wizard

9
Prepare the Source System for Rapid Clone

• Update applications context file
• Run AutoConfig to generate configuration files
  for the source system)
• Create the RDBMS home Rapid Clone files
• Run MakeAppsUtil to generate appsutil.zip files
  that contain Rapid Clone files
• Copy the Rapid Clone files to RDBMS home
• Update the Rapid Clone files on RDBMS home with
  the new files included in AutoConfig Consolidated
  Update patch
• Modify user configuration (for Unix users 11.5.1)

10
Stage the Source System

• Create the stage location (20 MB)
• Stage the source system RDBMS home
• Ran adclone.sh script with modestage and
  component dbTechStack
• Stage the source system database
• Ran adclone.sh script with modestage and
  component database
• Stage the Applications technology stack
• Ran adclone.sh script with modestage and
  component atTechStack
• Stage the APPL_TOP
• Ran adclone.sh script with modestage and
  component appltop
• Note The source system doesnt need to be shut
  down for the stage phase

11
Copy the Source System

• Create users for the target system
• Create the stage location
• Shutdown source system services
• Copy the source system clone stage directories
• Copy the source system APPL_TOP files
• Copy the source system COMMON_TOP files (java,
  html and util directories)
• Copy the source system Applications technology
  stack (8.0.6 home and iAS home)
• Copy the source system RDBMS home
• Copy the source system database

12
Configure the Target System

• Create the target system Applications Context
  file (use Context Creation Wizard)
• Configure the target system RDBMS home
• Ran adclone.sh script with modeapply and
  component dbTechStack
• Configure the target system database
• Start the target system database and Net8
  listener
• Configure the target system Applications
  technology stack
• Configure the target system APPL_TOP

13
Perform post-cloning tasks

• Sign the Java archive files (forcey)
• Relink the f60webmx executable on HP
• Relink Applications executables programs
  (recommended)
• Update Notifications Mailer configuration files
• Reconfigure Portal (Note 146469.1)
• Start Applications processes
• Test the target system
• Check client tier connectivity
• Verify that you can start and use target system

14
Perform post-cloning tasks

• Other post-cloning considerations
• Update GSM profile options
• Update other profile options (non-site level
  options)
• Update patch history database (see Migrating
  Patch History Info in AD Procedures guide)
• Update tables with target system environment
  information
• Additional product specific steps (for payroll)
• Remove source system related files and
  directories from the target system

15
Other cloning options

• Recloning
• Cloning a multi-node system to a multi-node
  system
• Required that number of nodes and server
  components installed on each node are the same
• Clone database node first
• Cloning a single-node system to a multi-node
  system - available
• Cloning a multi-node system to a single-node
  system not yet available

16
Which cloning method is best for your environment?

• The best method depends on
• Version of applications
• Prior to version 11.5.7
• Version 11.5.7
• Version 11.5.8
• Platform
• Unix (adclone.pl and Rapid Clone)
• Windows (adclone.pl and AutoConfig)
• Version of Database
• 8i
• 9i

17
What cloning options are available for each
method?
