Prepare for merging APPL_TOPs

Prepare for merging APPL_TOPs


1. Maintain snapshot on each tier using adadmin

****Below steps - # 2 and #3 to be executed in parallel to save time
2. Log in to the PRIMARY node: (1 hour)

Follow metalink note 390629.1

Replace
$resultclone = system "$syscmd";
# added for bug #4448838
if($resultclone ! = 0 )

With
my $resultclone = system "$syscmd";
# added for bug #4448838
if($resultclone !=0 )


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


3. Log in as the APPLMGR user to each of the secondary nodes being merged and run: (/u01/app/oracle/product/iAS/ this HOME needs the OUI patch for DB/CCM tiers) – Takes 30 mins can be done in parallel to #3

Apply patch# 5035661 (cp -p /u01/app/oracle/product/oraInventory/ContentsXML/comps.xml /u01/app/oracle/product/iAS/inventory/ContentsXML/comps.xml)
unzip -od p5035661_11i_.zip
cd /appsoui/setup
perl OUIsetup.pl

cd $COMMON_TOP/admin/scripts/
perl adpreclone.pl appltop merge

a. Create a copy of Node A (optional)
If you want to place the merged APPL_TOPs in a new location instead of using an existing APPL_TOP location, create a copy of Node A (the other nodes in the system do not need to be copied). Include the following directories from Node A:

(when this directory exists)

/util
/clone
/_pages (when this directory exists)
<806 ORACLE_HOME>

4. Copy the required files for merging (10 mins)
Log in as the APPLMGR user to each source node and recursively copy:
 directory $COMMON_TOP/clone/appl from secondary node
- to -
 directory $COMMON_TOP/clone/appl on Primary node
(or the copy of Node A).
