First
we have created a directory named “tatrac”. This
directory will be used as an external tier instance top.
After
setting apps env, run this command.
cd
$COMMON_TOP/clone/bin
perl
adclonectx.pl
contextfile=/A01/TATTRNG2/inst/apps/TRAINING_london001/appl/admin/TRAINING_london001.xml
outfile=/A01/TATTRNG2/tatrac/tatrac_ext.xml
Give
following input as follows.

Complete
port information available at

-------------
Keep
port values of target system same, else db ports will be changed.
Then
create the following directory as mentioned below.
-------------
$
grep s_config_home /A01/TATTRNG2/tatrac/tatrac_ext.xml
<config_home
oa_var="s_config_home">/A01/TATTRNG2/tatrac/apps/TRAINING_tatrac</config_home>
$
mkdir -p /A01/TATTRNG2/tatrac/apps/TRAINING_tatrac
[
bin]$ grep s_ora_config_home /A01/TATTRNG2/tatrac/tatrac_ext.xml
<ora_config_home
oa_var="s_ora_config_home">/A01/TATTRNG2/tatrac/apps/TRAINING_tatrac/ora</ora_config_home>
[
bin]$ mkdir -p /A01/TATTRNG2/tatrac/apps/TRAINING_tatrac/ora
[
bin]$ grep s_logs_dir /A01/TATTRNG2/tatrac/tatrac_ext.xml
<logs_dir
oa_var="s_logs_dir">/A01/TATTRNG2/tatrac/apps/TRAINING_tatrac/logs</logs_dir>
[
bin]$ mkdir -p /A01/TATTRNG2/tatrac/apps/TRAINING_tatrac/logs
[
bin]$ grep s_pids_dir /A01/TATTRNG2/tatrac/tatrac_ext.xml
<pids_dir
oa_var="s_pids_dir">/A01/TATTRNG2/tatrac/apps/TRAINING_tatrac/pids</pids_dir>
[
bin]$ mkdir -p /A01/TATTRNG2/tatrac/apps/TRAINING_tatrac/pids
------------------------------
Now,
check the port pool usage and port conflicts in new context file as
discussed below.
Verify
java is running from following location.
$
which java
/A01/TATTRNG2/apps/tech_st/10.1.3/appsutil/jdk/jre/bin/java
Now,
say your internal tier is running on port pool 7 [if http port on
8007], start the internal tier components and run this command.
[
bin]$ java oracle/apps/ad/util/PortPool -e
/A01/TATTRNG2/tatrac/tatrac_ext.xml -pool 7
Log
file located at PortPool_03100747.log
PORT
POOL 7 is in use
[
bin]$ grep RC-50204 PortPool_03100747.log

For
the most part, the specific ports do have to be changed, but the port
ranges do not. In almost all cases, the port ranges supplied are
large enough to comfortably accommodate both web tiers.
Before:
(this isn't the only 4443 in the context file)
<web_ssl_port
oa_var="s_webssl_port" oa_type="PORT" base="4443"
step="1"
range="-1"
label="Web SSL Port">4443</web_ssl_port>
After:
<web_ssl_port
oa_var="s_webssl_port" oa_type="PORT" base="4444"
step="1"
range="-1"
label="Web SSL Port">4444</web_ssl_port>
------------------
Change
the following lines as follows after changing the codes.
<TIER_DB
oa_var="s_isDB">NO</TIER_DB>
<TIER_ADMIN
oa_var="s_isAdmin">NO</TIER_ADMIN>
<TIER_WEB
oa_var="s_isWeb">YES</TIER_WEB>
<TIER_FORMS
oa_var="s_isForms">NO</TIER_FORMS>
<TIER_NODE
oa_var="s_isConc">NO</TIER_NODE>
<TIER_FORMSDEV
oa_var="s_isFormsDev">NO</TIER_FORMSDEV>
<TIER_NODEDEV
oa_var="s_isConcDev">NO</TIER_NODEDEV>
<TIER_WEBDEV
oa_var="s_isWebDev">YES</TIER_WEBDEV>
Additional
edits
1.
Set the webentry point, s_webentryhost, to the reverse proxy server
hostname.
Final
value = <webentryhost
oa_var="s_webentryhost">tatrac</webentryhost>
2.
Set the webentry domain, s_webentrydomain, to the domain name of the
reverse proxy server.
Final
value = <webentrydomain
oa_var="s_webentrydomain">rainycloud.com</webentrydomain>
3.
Set the active webport, s_active_webport, to the reverse proxy
listener port.
Final
value = <activewebport oa_var="s_active_webport"
oa_type="DUP_PORT" base="8000" step="1"
range="-1" label="Active Web Port">443</activewebport>
4.
Set the webentry protocol, s_webentryurlprotocol, to the webentry
point protocol e.g.; "http" or "https".
Final
value = webentryurlprotocol
oa_var="s_webentryurlprotocol">https</webentryurlprotocol>
5.
Set the login page, s_login_page, to <webentry
protocol>://<webentry point>.<webentry domain>:<active
webport>. Replace <webentry protocol>, <webentry point>,
<webentry domain>, and <active webport> with their
respective values.
Final
value = <login_page
oa_var="s_login_page">https://tatrac.rainycloud.com:443/OA_HTML/AppsLogin</login_page>
6.
Set the reverse proxy server address, s_server_ip_address to the IP
address of the reverse proxy server.
Final
value = <login_page
oa_var="s_login_page">https://tatrac.rainycloud.com:443/OA_HTML/AppsLogin</login_page>
7.
Confirm that the value of s_oc4j_cluster_nodes indicates the actual
middle tier and free port and not the name of the reverse proxy
server. For example:
Original
(clearly wrong):
<oc4j_cluster_nodes
oa_var="s_oc4j_cluster_nodes">external.us.oracle.com:6200</oc4j_cluster_nodes>
Change
(Use internal tier hostname and new port. This port is the same as
the s_ons_remoteport which may be busy. See "Outstanding Issues
1, below) :
<oc4j_cluster_nodes
oa_var="s_oc4j_cluster_nodes">dcoll12xc.us.oracle.com:6201</oc4j_cluster_nodes>
Final
value = <oc4j_cluster_nodes
oa_var="s_oc4j_cluster_nodes">london001.rainycloud.com:6212</oc4j_cluster_nodes>
Very
very important =
s_oc4j_cluster_nodes
nodes should point to any free port[You may check it using netstat
command]. In our case it is 6212. Also, you need to change
s_ons_remoteport port value to the above port.
<ons_remoteport
oa_var="s_ons_remoteport" oa_type="PORT"
base="6200" step="1" range="-1"
label="ONS Remote Port">6212</ons_remoteport>
8.
If your reverse proxy server is also working as an SSL accelerator,
then remove the '#' to use ssl_terminator.conf in ssl terminated
environments. In XML syntax, this means:
Change
the following line from this:
<sslterminator
oa_var="s_enable_sslterminator">#</sslterminator>
to
this:
<sslterminator
oa_var="s_enable_sslterminator"/>
Final
value = <sslterminator oa_var="s_enable_sslterminator"/>
--------------------
After
changing the above in context file, do the following steps.
$AD_TOP/bin/adconfig.sh
Enter
the full path to the Context file:
/A01/TATTRNG2/tatrac/tatrac_ext.xml
Enter
the APPS user password:
After
setting the new env file, try to restart the new instance top using
adstrtall.sh scripts.
You
can check whether new instance is working or not by simply checking
whether web port is listening or not through netstat command.

After
configuring external tier, in the web box, install and configure
Apache as mentioned in the doc 380490.1 for this external tier to
work..
