Cloning of Multi Node to Single Node

Multi Node To Single Node Cloning

Cloning of Multi Node to Single Node

We have architecture like this

Node 1: DB and CM
Node 2: FORMS, WEB, REPORTS, Admin node

we want to clone this to Single Node (Database tier and Appication Tier)

steps:

(a) Prepare source database tier

$ cd $ORACLE_HOME/appsutil/scripts/<conext_name>
$perl adpreclone.pl dbTier

(b) prepare appl top for merge in Source Node1 ( DB and CM )

$cd $COMMON_TOP/admin/scripts/<CONTEXT_NAME>
$perl adpreclone.pl apptop merge

(c) prepare appl top for merge in source node 2 ( forms,web,reports,admin)

$cd $COMMON_TOP/admin/scripts/<context_name>
$perl adpreclone.pl appsTier merge

shutdown the source nodes and copy the following files

(1)  copy the files from source Application Tier( FORMS,WEB,REPORTS AND ADMIN) FILES TO TARGET APPLICATION TIER

8.0.6 ORACLE_HOME
IAS ORACLE_HOME
APPL_TOP
COMMON_TOP

(2)  copy the files from source CM node files to target appilcation tier

$COMMON_TOP/clone/appl to

target application tier

$COMMON_TOP/clone/appl direcotry

(3)  copy the Database tier file system to target database tier

Oracle home and database files

Prepare the target node for cloning

database tier:

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

application tier:

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

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

Clean up of the target system
Remove the temporary directory [COMMON_TOP]/clone/appl to reduce disk space
usage.
