Maintain snapshot information Log in as the applications user on each application tier node and run 'Maintain Snapshot Information' by using adadmin. Merge existing APPL_TOPs Log in to the primary node of your application tier as the application user user and run: $ cd [COMMON_TOP]/admin/scripts/[CONTEXT_NAME] $ perl adpreclone.pl appsTier merge This will prompt you with option to merge secondary nodes Now log in as the applications user to each of the secondary application tier nodes being merged and run: $ cd [COMMON_TOP]/admin/scripts/[CONTEXT_NAME] $ perl adpreclone.pl appltop merge Prepare the source system database tier. Log on to the database tier of the source system as the oracle user and run the following commands: $ cd [RDBMS ORACLE_HOME]/appsutil/scripts/[CONTEXT_NAME] $ perl adpreclone.pl dbTier With this all the pre clone tasks on the source system have been completed. Create OS user accounts Create a OS user account for your applications $ useradd -g dba -d [home_directory] -p password username Similarly create a OS user account for your database. Modify the orainventory to reflect the new location $ vi /etc/oraInst.loc

Copy the following application tier directories Copy the following application tier directories from the primary node of your source system to the target application tier node, retaining the original directory structure: [APPL_TOP] [OA_HTML] [OA_JAVA] [COMMON_TOP/util] [COMMON_TOP/clone> [806 ORACLE_HOME] [iAS ORACLE_HOME] Copy the required files for merging Log in as the applications user to each of the secondary source nodes and recursively copy: directory [COMMON_TOP]/clone/appl - to directory [COMMMON_TOP]/clone/appl on the target system node Before proceeding with the next steps you must shutdown your oracle applications services and the database on the source system. Copy the database tier file system Log on to the source system as the database user Copy the database (DBF) files from the source to the target system Copy the source database ORACLE_HOME to the target system After this you can now startup the database and applications services on your source system and release it for use. Configure the target system database server Log on to the target system as the database user and type the following commands to configure and start the database: $ cd [RDBMS ORACLE_HOME]/appsutil/clone/bin $ perl adcfgclone.pl dbTier This will prompt for new ORACLE_SID,ORACLE_HOME,Port Pool,JAVA_TOP and DATA_TOP give the appropriate values matching your target system Once successful this should start your database and listener.

Configure the application tier server nodes The database and its listener should remain up before executing the next set of commands. Log in to the merged APPL_TOP node as the applications user and execute the following commands: $ cd [COMMON_TOP]/clone/bin $ perl adcfgclone.pl appsTier This will prompt you new port pool for applictaion tier services as well as new APPLTOP,COMMON_TOP,ORACLE_HOME and IAS_TOP Successful completion of this task will bring up your application tier services on the target or the cloned node. Post Clone Tasks Log in to the target system application tier node as the APPLMGR user. Run the following tasks in adadmin for all products: o generate JAR files o generate message files o relink executables o copy files to destination
