Cloning Oracle Applications Release 12 with Rapid Clone

Section 1: Prerequisites (First time only)

1. Run AutoConfig on the Application Tiers

Run AutoConfig on all application tier nodes. Use the adautocfg.sh command. All scripts listed below are located in <INST_TOP>/admin/scripts.

Platform	Functionality	Command
UNIX	Start Applications services	adstrtal.sh
	Stop Applications services	adstpall.sh
	Run AutoConfig	adautocfg.sh

Attention: The database server and the database listener must remain available during the AutoConfig run. Only the application tier servers should be shut down.

Note: Running AutoConfig may change your existing environment files. After running AutoConfig, you should always set the environment before you run any Applications utilities, in order to apply the changed environment variables.

2. Synchronize appsutil on the Database Tier Nodes

Update the RDBMS ORACLE_HOME file system with the AutoConfig files by performing the following steps:

• On the application tier (as the APPLMGR user):

o   Log in to the APPL_TOP environment (source the environment file)

o   Create appsutil.zip file

perl <AD_TOP>/bin/admkappsutil.pl

o   This will create appsutil.zip in <INST_TOP>/admin/out

• On the database tier (as the ORACLE user):

o   Copy or FTP the appsutil.zip file to the <RDBMS ORACLE_HOME>

o   cd <RDBMS ORACLE_HOME>

o   unzip -o appsutil.zip

3. Run AutoConfig on the Database Tier

Run AutoConfig on the database tier nodes. Use the adautocfg.sh/.cmd command. All the scripts listed below are located in

<RDBMS ORACLE_HOME>/appsutil/scripts/<CONTEXT_NAME>.

Platform	Functionality	Command
UNIX	Start database listener process	addlnctl.sh start <SID>
	Start database process	addbctl.sh start
	Stop database listener process	addlnctl.sh stop <SID>
	Stop database process	addbctl.sh stop
	Run AutoConfig	adautocfg.sh

Attention: The database server and the database listener must remain available during the AutoConfig run. All the other database tier services should be shut down.

Note: Running AutoConfig may change your existing environment files. After running AutoConfig, you should always set the environment before you run any Applications utilities, in order to apply the changed environment variables.

4. Maintain Snapshot information

Log in to each Applications Node as the APPLMGR user, and run “Maintain Snapshot information” in AD Administration (adadmin).

Run adadmin à Select option 2 à Select option 5 à Select option 2 à Select option 1

Section 2: Clone Oracle Applications Release 12

There are three phases to the cloning process:

1. Prepare the Source System
   Execute the following commands to prepare the source system for cloning.
2. Prepare the source system database node for cloning
   Log 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

NOTE:

First set the environment variable

. /oracle/db/tech_st/10.2.0/PROD_devdb.env

Then

cd $ORACLE_HOME/appsutil/scripts/PROD_devapps/

perl adpreclone.pl dbTier

1. Prepare the source system application tier for cloning
   Log 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:

First set the environment variable

. /oracle/apps/apps_st/appl/PROD_devapps.env

Then

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

2. Copy the Source System to the Target System
   Copy 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.
3. Copy the application tier file system
   Log on to the source system application tier nodes as the APPLMGR user.

•   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>
• Tech Stack

Note: Restore the backup of source Apps on target Apps.

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

• Perform a normal shutdown of the source system database
• Copy the database (DBF) files from the source to the target system
• Copy the source database ORACLE_HOME to the target system
•    Start the source Applications system database and application tier processes

Note: Copy and Restore the backup of source DB on target DB.

From source system e.g., PRODDB:

 scp 01_BACKUP_PRODDB.tar.gz oracle@172.16.35.9:/oracle/01_BACKUP_PRODDB.tar.gz

From target system e.g., DEVDB

tar -xzf /oracle/01_BACKUP_PRODAPPS.tar.gz

Same for APPS node.

1. Configure the Target System
   Execute the following commands to configure the target system. You will be prompted for the target system specific values (SID, paths, ports, etc.)
   1. Configure the target system database server
      Log on to the target system as the ORACLE user and enter the following commands to configure and start the database:
      cd <RDBMS ORACLE_HOME>/appsutil/clone/bin
      perl adcfgclone.pl dbTier

NOTE:

[oracle@testdb ~]$ cd $ORACLE_HOME

Section 3: Finishing Tasks (If Required)

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

1. Update profile options
   Rapid 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 settings
   If the new cloned system needs to utilize different printers, update the target system with the new printer settings now.
3. Update Workflow configuration settings
   Cloning an Oracle Applications instance will not update the host and instance specific information used by Oracle Workflow. Review the following tables and columns to verify there is no instance specific data in the Workflow configuration on the target system.

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_VALUE	Value starts with “http://<old web host> : Update to new web host
WF_SYSTEMS	GUID	Create a new system defined as the new global database name using the Workflow Administrator Web Applications responsibility.
WF_SYSTEMS	NAME	Value needs to be replaced with the database global name
WF_AGENTS	ADDRESS	Update database link with the new database global name.
FND_FORM_FUNCTIONS	WEB_HOST_NAME	Update with the new web host name
FND_FORM_FUNCTIONS	WEB_AGENT_NAME	Update to point at the new PLSQL listener name
FND_CONCURRENT_REQUESTS	LOGFILE_NAME	Update with the correct path to the logfile directory
FND_CONCURRENT_REQUESTS	OUTFILE_NAME	Update with the new directory path on the target system

4. Verify the APPLCSF variable setting
   Source 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_PARAMETERS
   If 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.
