R12 clone with shared appl_top(NFS mount)

Assume your R12 has two nodes:
node1: apps(root+web_entry+web_application+batch_process)+db
  three mount point:
   /local (local mount, INST_TOP)
   /shared (SAN mount, and NFS out, stores application's APPL_TOP, ORACLE_HOME,      IAS_ORACLE_HOME, COMMON_TOP)
   /db (SAN for database)


node2: apps(root+web_entry+web_application)
   only one mount
   /local (local mount, INST_TOP)


Prepare the source system
Execute the following commands to prepare the source system for cloning:
a.Prepare the source system database tier 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


b.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


Copy the application tier file system
you only need to copy the files in node1.

Copy the database node file system


Configure the target systemRun 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 server
Log 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 nodes
Log on to the target system as the APPLMGR user and enter the following commands:
$ cd [COMMON_TOP]/clone/bin
$ perl adcfgclone.pl appsTier


Add nodes into apps server.
 1. in the node you mount the application(node1),
     cd [COMMON_TOP]/clone/bin
     perl adclonectx.pl addnode contextfile=$CONTEXT_FILE


 2. in node2
     cd [COMMON_TOP]/clone/bin
     mkdir -p /local/inst/apps/$CONTEXT_NAME (create the directory)
     perl [AD_TOP]/bin/adconfig.pl contextfile=<the xml file generated in step 1>
