In Oracle E-Business Suite Release 12.2, some configurations are managed via AutoConfig, and some are managed natively via Fusion Middleware Control and WebLogic Server Administration Console. A new mechanism has been introduced to keep the context variables and the OHS configuration parameters (where applicable) in synchronization. This mechanism is called the 'feedback loop'. The SyncContext tool is one of the tools used for explicit synchronization of the context variables with the WLS configuration parameters.
This tool can be run on all application tier nodes as follows:
On UNIX:
$ perl /bin/adSyncContext.pl contextfile=
Scenario: Changing WebPort from 8000 to 8001
$ grep 8000 $CONTEXT_FILE
$
$ pwd

$ cp httpd.conf httpd.conf_bkup
$ diff httpd.conf httpd.conf_bkup

Autoconfig
If autoconfig is run at this time then changes will be in place.
Oh that is a lot of change I do not want to do it now. So reverting back.
$ pwd
/inst122i/applmgr/fs1/FMW_Home/webtier/instances/EBS_web_INST122I_OHS1/config/OHS/EBS_web_INST122I
$ cp httpd.conf_bkup httpd.conf
$ grep -i listen httpd.conf
# Listen: Allows you to bind Apache to specific IP addresses and/or
# Change this to Listen on specific IP addresses as shown below to
# Listen 12.34.56.78:80
# OHS Listen Port
Listen 8000

I reran the adSyncContext.pl that will update the new values to the context file again.
$ perl $AD_TOP/bin/adSyncContext.pl contextfile=$CONTEXT_FILE
Enter the APPS user password:
Enter the WebLogic AdminServer password:
The log file is /inst122i/applmgr/fs1/inst/apps/INST122I_testserver01/logs/appl/rgf/Thu_Nov_28_00_01_25_2013/adSyncContext.log
$
$ grep -i 8001 $CONTEXT_FILE
$
There are references to 8001 port which has been reverted back.
$
$ grep -i 8000 $CONTEXT_FILE
$
This scenario shows how SyncContext.pl drives the changes to HTTP Server.
