Terminology

Cloning is the process used to create a copy of an existing Oracle Applications system. There are various scenarios for cloning an Oracle Applications system, including:

Standard cloning - Making a copy of an existing Oracle Applications system, for example a copy of a production system to test updates.

System scale-up - Adding new machines to an Oracle Applications system to provide the capacity for processing an increased workload.

System transformations - Altering system data or file systems, including actions such as platform migration, data scrambling, and provisioning of high availability architectures.

Patching and upgrading - Delivering new versions of Applications components, and providing a mechanism for creating rolling environments to minimize downtime.

An important principle in Oracle Applications cloning is that the system is cloned, rather than the topology. Producing an exact copy of the patch level and data is much more important than creating an exact copy of the topology, as a cloned system must be able to provide the same output to the end user as the source system. However, while a cloned system need not have the full topology of its source, it must have available to it all the topology components that are available to the source.

Note: The Cloning methodology posted on this document requires full Autoconfig compliance.

Warning: Failing to use the latest code may jeopardize the success of the clone. If new Rapid Clone or AutoConfig updates are applied to the system, steps 6, 7, and 8 below must be executed again in order to apply the new files to the database node.

6. Run AutoConfig on the application tiersFollow the steps under section " Run AutoConfig on the Application Tiers " in My Oracle Support Knowledge Document 387859.1 to run AutoConfig on all application tier nodes.

7. Synchronize appsutil on the database tier nodesFollow the steps under section "Copy AutoConfig to the RDBMS ORACLE_HOME" in My Oracle Support Knowledge Document 387859.1 to copy AutoConfig and Rapid Clone files to each database node via the admkappsutil.pl utility.

8. Run AutoConfig on the database tierFollow the steps under section "Run AutoConfig on the Database Tier" in My Oracle Support Knowledge Document 387859.1 to run AutoConfig on the database tier nodes.

9. Maintain Snapshot InformationLog in to each application tier node as the APPLMGR user, and run "Maintain Snapshot Information" in AD Administration. To update the snapshot, please select the following options "Update Current View Snapshot" and "Update Complete APPL_TOP".

Note: If a snapshot was never created for that APPL_TOP, you will need to create a new one before proceeding with the clone. Refer to Oracle Applications Maintenance Utilities for more information (this is the Release 12.1 version; versions for earlier releases are also available from the Oracle E-Business Suite Online Documentation Library).

Section 2: Cloning Tasks

Use Rapid Clone to create template files for cloning on the source system. After the source system is copied to the target, Rapid Clone updates these templates to contain the new target system configuration settings.

Note: Rapid Clone never changes the source system configuration.

The cloning process consists of three phases, each of which is made up of several logical sections and their steps.

1. Prepare the source systemExecute the following commands to prepare the source system for cloning:

a. Prepare the source system database tier for cloningLog on to the source system as the ORACLE user, and run the following commands:

$ cd [RDBMS ORACLE_HOME]/appsutil/scripts/[CONTEXT_NAME]$ perl adpreclone.pl dbTier

b. Prepare the source system application tier for cloningLog on to the source system as the APPLMGR user, and run the following commands on each node that contains an APPL_TOP:

$ cd [INST_TOP]/admin/scripts$ perl adpreclone.pl appsTier

Note: If new Rapid Clone or AutoConfig updates are applied to the system, adpreclone.pl must be executed again on the dbTier and on the appsTier in order to apply the new files into the clone directory structures that will be used during the cloning configuration stage.

2. Copy the source system to the target systemCopy the application tier file system from the source Applications system to the target node by executing the following steps in the order listed. Ensure the application tier files copied to the target system are owned by the target APPLMGR user, and that the database node files are owned by the target ORACLE user.

Note: In the copying tasks below, UNIX/Linux users should ensure that the symbolic links (soft links) are preserved when copying. On most UNIX platforms, this can be accomplished with the cp -RH command. Consult the UNIX man page for the cp command to check the parameters available on your platform.

For example: cd /target_dest_dir/db cp -RH /source_dir/db/*

Alternatively, the tar command can be used to compress the directories into a temporary staging area. UNIX/Linux users should ensure that the symbolic links (soft links) are preserved when compressing. On most UNIX platforms, this is the default behavior of tar command. Consult the UNIX man page for the tar command to check the parameters available on your platform

Additionally, verify the permissions of the executables under ORACLE_HOME/bin that can potentially be owned by root (i.e. nmo, nmhs, nmb, etc).

a. Copy the application tier file systemLog on to the source system application tier nodes as the APPLMGR user and shut down the application tier server processes. Copy the following application tier directories from the source node to the target application tier node:

[APPL_TOP] [COMMON_TOP] Applications Technology Stack:

[OracleAS Tools ORACLE_HOME] [OracleAS Web IAS_ORACLE_HOME]

b. Copy the database node file systemLog on to the source system database node as the ORACLE user, and then:

1. Perform a normal shutdown of the source system database2. Copy the database (.dbf) files from the source system to the target system3. Copy the source database ORACLE_HOME to the target system4. Start the source Applications system database and application tier

processes

3. Configure the target system

Run the following commands to configure the target system. You will be prompted for specific target system values such as SID, paths, and ports.

a. Configure the target system database serverLog on to the target system as the ORACLE user and enter the following commands:

$ cd [RDBMS ORACLE_HOME]/appsutil/clone/bin$ perl adcfgclone.pl dbTier

b. Configure the target system application tier server nodesLog on to the target system as the APPLMGR user and enter the following commands:

$ cd [COMMON_TOP]/clone/bin$ perl adcfgclone.pl appsTier

4. Note: If you are cloning between different versions of the Operating System (e.g. Linux 5 to Linux 4) it is recommended that you relink the AD_TOP product binaries using [adrelinknew "ad all"] followed by APPL_TOP executables with adadmin.

Section 3: Finishing Tasks

This section lists tasks that may be necessary, depending on your implementation and the intended use of the cloned system.

1. Update profile optionsRapid Clone updates only site level profile options. If any other profile options are set to instance specific values, you must update them manually.

2. Update printer settingsIf the new cloned system needs to utilize different printers, update the target system with the new printer settings now.

3. Update Workflow configuration settingsCloning an Oracle Applications instance will not update the host and instance-specific information used by Oracle Workflow. Review the tables and columns listed in Table 4 to check for any instance-specific data in the Workflow configuration on the target system.

Table 4: Workflow configuration settings

Table Name Column Name Column Value Details

WF_NOTIFICATION_ATTRIBUTES TEXT_VALUE Value starts with http://[old web host]: Update to new web host.

WF_ITEM_ATTRIBUTE_VALUES TEXT_VALUEValue starts with "http://[old web host]: Update to new web host.

WF_SYSTEMS GUID

Using the Workflow Administrator Web Applications responsibility, create a new system defined as the new global database name.

WF_SYSTEMS NAMEReplace value with the database global name.

WF_AGENTS ADDRESSUpdate database link with the new database global name.

FND_FORM_FUNCTIONS WEB_HOST_NAMEUpdate with the new web host name.

FND_FORM_FUNCTIONS WEB_AGENT_NAMEUpdate to point at the new PL/SQL listener name.

FND_CONCURRENT_REQUESTS LOGFILE_NAMEUpdate with the correct path to the logfile directory.

FND_CONCURRENT_REQUESTS OUTFILE_NAMEUpdate with the new directory path on the target system.

4. Verify the APPLCSF variable settingSource the APPS environment and review that the variable APPLCSF (identifying the top-level directory for concurrent manager log and output files) points to a suitable directory. To modify it, change the value of the s_applcsf variable in the context file and then run AutoConfig.

5. Update the SESSION_COOKIE_DOMAIN value in ICX_PARAMETERSIf the target system is in a different domain name than the source system and SESSION_COOKIE_DOMAIN was not null in the source system, update that value to reflect the new domain name.

6. Re-Implement SSL and SSO configurationIf the Source System was SSL or SSO enabled, and the Target is wished to be SSL or SSO enabled, then reconfigure the Target by following the SSL/SSO documentation. Otherwise, if the Target is wished to be non-SSL or non-SSO, then follow the same SSL/SSO documentation to undo the SSL/SSO setup.

Section 4: Advanced Cloning Options

This section describes various advanced cloning procedures that may need to be employed in the appropriate circumstances.

Option 1: Refreshing a Target System

You may need to refresh the target system periodically to synchronize it with changes to the source system.

Note: Back up the target context file on the target system before refreshing the database or application tiers.

To refresh the target system, perform the following steps as described in previous sections:

1. Prepare the source system .

2. Copy the source system to the target system.

a. If the application tier file system if the APPL_TOP, COMMON_TOP, or technology stack needs to be refreshed, copy the portion of the application tier file system that has been updated

b. If the RDBMS ORACLE_HOME or the database needs to be refreshed, copy the database node file system. If refreshing the database, the ORACLE_HOME should be refreshed at the same time.

3. Configure the target system .

Specify the existing target system context file when running adcfgclone.pl commands.

a. Configure the target system database server by logging on to the target system as the ORACLE user and entering the following commands to configure and start the database:

$cd [RDBMS ORACLE_HOME]/appsutil/clone/binperl adcfgclone.pl dbTier [Database target context file]

Where Database target context file is [RDBMS ORACLE_HOME]/appsutil/[Target CONTEXT_NAME].xml

b. Configure the target system application tier server nodes by logging on to the target system as the APPLMGR user and entering the following commands:

$ cd [COMMON_TOP]/clone/bin$ perl adcfgclone.pl appsTier [APPL_TOP target context file]

Where APPL_TOP target context file is [INST_TOP]/appl/admin/[Target CONTEXT_NAME].xml

4. Perform the standard finishing tasks.

Option 2: Cloning a Multi-Node System

This procedure allows the source system or target system to be a multi-node system. As of Release 12, all APPL_TOPs are unified APPL_TOPs. This means that all files required for all application tier services are installed on every application tier node. Thus, only one copy of the applications tier node files needs to be copied to the target system, regardless of whether a shared file system is being used on the source or target system. Multiple application tier nodes are distinguished from each other by the services running.

1. Perform the standard prerequisite tasks.

Carry out these steps on all source and target nodes.

2. Carry out the previously-described cloning tasks.

Prepare, copy and configure the cloned Applications system. When creating more than one application tier node on the target system, follow these steps:

1. Perform a full clone (Prepare, copy and configure steps) of the database node and primary application tier node.

2. To add shared application tier nodes on the target system, follow the instructions in My Oracle Support Knowledge Document 384248.1, Section 4: Adding a node to a Shared Application Tier File System.

3. To add non-shared application tier nodes, execute the copy and configure steps as on the primary node.

4. Specify the services to start on each target Applications tier node when responding to the prompts during the configuration step.

3. Perform the required finishing tasks

Option 3: Adding a New Node to an Existing System

You can use Rapid Clone to clone a node and add it to the existing Applications system, a process also known as scale up or scale out. The new node can run the same services as the source node, or different services. Follow the instructions in the Application tier part of Cloning Tasks.

1. Prepare the source system, copy it to the new node and configure it.

2. After adcfgclone.pl completes, source the Applications environment and run the following commands on the target system:

$ cd [COMMON_TOP]/clone/bin$ perl adaddnode.pl

Note: After adding new nodes, refer to My Oracle Support Knowledge Document 380489.1 for details of how to set up load balancing.

Note: If SQL*Net Access security is enabled in the existing system, you first need to authorize the new node to access the database through SQL*Net. See the Oracle Applications Manager on line help for instructions on how to accomplish this.

Option 4: Cloning an Oracle RAC system

For instructions on how to Clone RAC-Enabled Systems with Rapid Clone, refer to My Oracle Support Knowledge Document 559518.1.

Option 5: Adding a Node to an Existing Oracle RAC Cluster

From Release 12, Rapid Clone is no longer used to migrate a database tier to Oracle RAC. Refer to My Oracle Support Knowledge Document 388577.1 for instructions on how to perform this task.

Option 6: Cloning the Database Separately

Some situations require the database to be recreated separately, without using Rapid Clone. Typical scenarios are when system downtime is not feasible, or advanced database replication tools like RMAN are being used to copy the database in hot backup mode.

This section documents the steps needed to allow manual creation of the target database control files within the Rapid Clone process. This method needs to be used for databases located on raw partitions, or when cloning a hot backup. Follow the complete steps in Cloning Tasks, but replace Step 3a (Configure the target system database server) with the following steps:

1. Log on to the target system as the ORACLE user

2. Configure the [RDBMS ORACLE_HOME]

$ cd [RDBMS ORACLE_HOME]/appsutil/clone/bin$ perl adcfgclone.pl dbTechStack

3. Create the target database control files manually

In this step, you copy and recreate the database using your preferred method, such as RMAN restore, Flash Copy, Snap View, or Mirror View.

4. Start the target database in open mode

5. Run the library update script against the database

$ cd [RDBMS ORACLE_HOME]/appsutil/install/[CONTEXT NAME]$ sqlplus "/ as sysdba" @adupdlib.sql [libext]

Where [libext] should be set to 'sl' for HP-UX, 'so' for any other UNIX platform, or 'dll' for Windows.

6. Configure the target database

The database must be running and open before performing this step.

$ cd [RDBMS ORACLE_HOME]/appsutil/clone/bin$ perl adcfgclone.pl dbconfig [Database target context file]

Where Database target context file is: [RDBMS ORACLE_HOME]/appsutil/[Target CONTEXT_NAME].xml.

Note: The dbconfig option will configure the database with the required settings for the new target, but it will not recreate the control files.
