Steps to add second node to an Application Tier in R12.2.
1. Start the admin server in the run file system of the applications first node and execute txkManageDBConnectionPool.pl script
Connect to the first node of the application server firstappserver-01q,
Source the environment file and set run file system
Start the admin server from run file system.
a. cd $ADMIN_SCRIPTS_HOME
b. echo $FILE_EDITION
c. sh adadminsrvctl.sh start
d. perl $FND_TOP/patch/115/bin/txkManageDBConnectionPool.pl
e. give option “”updateDSPassword”” as input for the above statement
2. Start the admin server in the patch file system of the applications first node
Connect to the first node of the application server firstappserver-01q,
Source Patch File system in the env file.
Start the admin server from patch file system.
a. cd $ADMIN_SCRIPTS_HOME
b. $INST_TOP/admin/scripts/adadminsrvctl.sh start forcepatchfs
3. Run adpreclone on run file system of the Target Applications
Connect to the first node of the application server firstappserver-01q,
Source the environment file and set run file system
a. cd $ADMIN_SCRIPTS_HOME
b. ls adpreclone.pl
c. perl adpreclone.pl appsTier
4. Modify the pairsfile to add node
Connect to the first node of the application server firstappserver-01q,
Running preclone will generate a pairfile like *run*.txt
$ cd $INST_TOP/appl/admin
$ ls -lrth *run*
for example, a file like this will be generated ebsenv_firstappserver-01q_run.txt
Make the necessary modifications to the following parameters in the pairsfile and copy it to the second node of the application server.
s_temp
s_contextname
s_hostname
s_domainname
s_cphost
s_webhost
s_config_home
s_inst_base
s_display
s_forms-c4ws_display
s_ohs_instance
s_webport
s_http_listen_parameter
s_https_listen_parameter
s_web_applications_status
s_web_entry_status
s_apcstatus
s_root_status
s_batch_status
s_other_service_group_status
s_adminserverstatus
s_web_admin_status
5. Add nodes to the Target Applications
connect to second node of the application server that needs to be added secondappserver-02q,
$ export BASEDIR=/sample/baselocation/apps
$ export PATH=$BASEDIR/fs1/FMW_Home/webtier/perl/bin:$PATH
$ cd $BASE_DIR/fs1/clone/bin/
$ /sample/baselocation/apps/fs1/FMW_Home/webtier/perl/bin/perl ./adclonectx.pl addnode contextfile=/sample/baselocation/apps/pairsfiles/ebsenv_firstappserver-01q.xml pairsfile=/pairsfiles_location/fs1_Secondnode_02q.txt outfile=/sample/baselocation/apps/fs1/inst/apps/ebsenv_secondappserver-02q/appl/admin/ebsenv_secondappserver-02q.xml dualfs=yes
6. Run autoconfig and start the application services
