In Oracle Applications 11i & R12 (12i) all the configuration parameters are captured in two context files:
Application context file called the <CONTEXT_NAME>.xml contains the configuration information for the application tier & is located in $APPl_TOP/admin for each node of application tier.
Database context file called the <CONTEXT_NAME>.xml contains the configuration information for the database tier & is located in $ORACLE_HOME/appsutil/.
Details stored in the context file contains host names,domain name , directory structure, port numbers used ……
The AutoConfig feature of Oracle application manager(OAM) is used to update & manage context files.
Updating Context file
Suppose we want to update the active port from <original port no.> to 80 , for this we will edit the application context file as follows:
Step 1 :Start all services
$ $COMMON_TOP/admin/scripts/<context_name>/adstrtal.sh APPS/<apps password>
Step 2 :log on to OAM & click site map.
Step 3:Click AutoConfig from the list of System Configuration features in the Administration tab.
Step 4 : Click the Edit Parameter button for the application tier context file to access the Context File Parameters page & then click the system tab.
Step 5 : Click the Focus icon (blue triangle) for oa_web_server. This expands oa_web_server and shows the web server related parameters.
Step 6:Update the Web Port (s_active_webport) parameter from < Original port number> to 80.
Step 7 : Save it & answer the tab.Then logout of OAM
AutoConfig Script
The autoconfig script uses information from the context file to generate all applications configuration files & updates database profiles. It is located in
Application tier: $COMMON_TOP/admin/scripts/CONTEXT_NAME/adautoconfig.sh
Database tier: $ORACLE_HOME/appsutil/scripts/CONTEXT_NAME/adautoconfig.sh
Now we run the autoconfig script to reconfigure the oracle application system with the updated Applications context.
Step 1 : Stop all services
$ $COMMON_TOP/admin/scripts/<context_name>/adstpall.sh APPS/<apps password>
Step 2:Run the autoconfig script, $adautocfg.sh & respond to the prompts.
Step 3:Check log files for any errors.log file for autoconfig is adconfig.log & is located in
<APPL_TOP>/admin/<context_name>/log/MMDDhhmm/
Step 4: Restart all services :
$ $COMMON_TOP/admin/scripts/<context_name>/adstrtal.sh APPS/<apps password>
Rolling back an autoconfig session
Each execution of AutoConfig creates a roll back script in case you want to revert back to the previous configuration settings. For this we perform the following steps:
Step 1 :Shut down all services:
$ cd $COMMON_TOP/admin/scripts/<context_name>
$ adstpall.sh APPS/<APPS password>
Step 2:Restore AutoConfig session.
$ cd $APPL_TOP>/admin/<context_name>/out/MMDDhhmm
$ restore.sh
Step 3 : Restart all services:
$ $COMMON_TOP/admin/scripts/<context_name>/adstrtal.sh APPS/<APPS password>
Restoring the AutoConfig updated files and restarting the services allows you to log on to OAM.
Restoring the previous configuration
Now we run OAM AutoConfig to restore the Applications Context.
Step 1 :Log on to the Oracle Application Manager (OAM) & click site map.You will be able to log on but some services will be down.
Step 2: Click AutoConfig from the list of System Configuration features in the Administration tab.
Step 3 : Click the Show History button for the application tier context file to access the Context File History page.
Step 4 :Click the Show Differences from Current Configuration button to see the recently updated parameters & Select Restore Previous Value for the Web Port and Discoverer Port parameters.
Step 5 :Save & respond the tabs. Log out of OAM.
Step 6 :Shut down all services:
$ cd $COMMON_TOP/admin/scripts/<context_name>
$ adstpall.sh APPS/<APPS password>
Step 7 :Run the AutoConfig script, adautocfg.sh & Respond to the prompts.
Step 8 : View the log file and check for any errors.
Step 9 : Restart all services:
$ $COMMON_TOP/admin/scripts/<context_name>/adstrtal.sh APPS/<APPS password>
Step 10 :Log on to the Oracle Application Manager (OAM)
If the status of some services appears to be down, click the Refresh icon to update the
status.

Hi Neha,
This is a good doc.
Hi how u doing?
Well i have installed oracle apps 11i on my machine
but when i try to login through E-Business Home Page i get page cannot be found also my host entries are as follows
127.0.0.1 localhost mydomain mydomain.com
192.168.1.2 mydomain mydomain.com
@ Ankur, I am assuming your server IP is 192.168.1.2 and machine name is mydomain.com
if yes then change entry in /etc/hosts to
127.0.0.1 localhost.localdomain
192.168.1.2 mydomain.com mydomain
and bounce services (bounce middle tier and db tier and try accessing again)
Hi Atul
Thanks for ur kind reply
well i have done some changes
my machine name is hcl.mydomain.com
and now my host entries reads like this
127.0.0.1 localhost.localdomain
192.168.1.2 hcl.mydomain.com hcl
and i have added primary dns suffix as mydomain.com
also if u can tell me how to use and bounce services (bounce middle tier and db tier)

hi sir………
while iam connecting to 9i client on windows xp to apps11i server on OEL4.4 error was came.that is tns:connection closed
tns:lost contact
………
how to resolve?could u please send mail to me.
@ annonymous,
Error “tns:connection closed – tns:lost contact” means client connection was closed from database server side.
This could be for multiple reasons and to name few it could be because of
a) Network Error
b) DB Listener issue
c) Database Issue
Check in DB Listener log and Database alert log to start with.

Please let me know how could i resolve this problem
Best Regards,
V.Anjan
@ Anjan,
Check if your services are running or not
Check for Apache (OHS) and OC4J (3 OC4Js)
1. Set environment variable by running env file for middle tier
2. cd $ADMIN_SCRIPTS_HOME
3. adopmnctl[.bat] status
4. adapcctl[.bat] status
netstat -an (and see if port 8000 is listening or not where 8000 is OHS/Apache port for port pool 0)
[...] This is done by adding webcenter server name in s_trusted_portal in Context File and run AutoConfig here and here [...]
Hi Atul,
We are upgrading from 11.5.10.2 to R12.1.3. In 11i we have some DADs defined in wdbsrv.app and we used to manage them using custom autoconfig template file (wdbsrv.app under $FND_TOP/admin/template/custom). Now in R12 this file is no longer used, we need to migrate the DADs to dads.conf, which we are doing manually. Wondering if we can manage the dads.conf using custom template. I could not find any template file provided by Oracle (used adtmplreport.sh). How do we handle this? If there is no template file available can we create our own? How does autoconfig recognises this?
Appreciate your help.
