In Oracle Applications 11i & R12 (12i) all the configuration parameters are captured in two context files:<\/p>\n

Application context file<\/strong> called the <CONTEXT_NAME>.xml<\/strong> contains the configuration information for the application tier & is located in $APPl_TOP\/admin<\/strong> for each node of application tier.<\/p>\n

Database context file<\/strong> called the <CONTEXT_NAME>.xml<\/strong> contains the configuration information for the database tier & is located in $ORACLE_HOME\/appsutil\/<\/strong>.<\/p>\n

Details stored in the context file contains host names,domain name , directory structure, port numbers used\u00a0 ……<\/p>\n

The AutoConfig<\/strong> feature of Oracle application manager(OAM) is used to update & manage context files.
\nUpdating Context file<\/u><\/strong><\/p>\n

Suppose we want to update the active port from <original port no.> to\u00a080 , for this we will edit the application context file as follows:<\/p>\n

Step 1<\/strong> :Start all services
\n$ $COMMON_TOP\/admin\/scripts\/<context_name>\/adstrtal.sh APPS\/<apps password>
\nStep 2<\/strong> :log on to OAM & click site map.
\nStep 3<\/strong>:Click AutoConfig from the list of System Configuration features in the Administration tab.
\nStep 4<\/strong> : Click the Edit Parameter button for the application tier context file to access the Context File Parameters page & then click the system tab.
\nStep 5 <\/strong>: Click the Focus icon (blue triangle) for oa_web_server. This expands oa_web_server and shows the web server related parameters.
\nStep 6<\/strong>:Update the Web Port (s_active_webport) parameter from < Original port number> to 80.
\nStep 7 <\/strong>: Save it & answer the tab.Then logout of OAM<\/p>\n

AutoConfig Script<\/u><\/strong><\/p>\n

The autoconfig script uses information from the context file to generate all applications configuration files & updates database profiles. It is located in<\/p>\n

Application tier: $COMMON_TOP\/admin\/scripts\/CONTEXT_NAME\/adautoconfig.sh<\/p>\n

Database tier: $ORACLE_HOME\/appsutil\/scripts\/CONTEXT_NAME\/adautoconfig.sh<\/p>\n

Now we run the autoconfig script to reconfigure the oracle application system with the updated Applications context.<\/p>\n

Step 1<\/strong> : Stop all services
\n$ $COMMON_TOP\/admin\/scripts\/<context_name>\/adstpall.sh APPS\/<apps password>
\nStep 2<\/strong>:Run the autoconfig script, $adautocfg.sh & respond to the prompts.
\nStep 3<\/strong>:Check log files for any errors.log file for autoconfig is adconfig.log & is located in
\n<APPL_TOP>\/admin\/<context_name>\/log\/MMDDhhmm\/
\nStep 4<\/strong>: Restart all services :
\n$ $COMMON_TOP\/admin\/scripts\/<context_name>\/adstrtal.sh APPS\/<apps password>
\nRolling back an autoconfig session<\/u><\/strong><\/p>\n

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:<\/p>\n

Step 1<\/strong> :Shut down all services:
\n$ cd $COMMON_TOP\/admin\/scripts\/<context_name>
\n$ adstpall.sh APPS\/<APPS password>
\nStep 2<\/strong>:Restore AutoConfig session.
\n$ cd $APPL_TOP>\/admin\/<context_name>\/out\/MMDDhhmm
\n$ restore.sh
\nStep 3<\/strong> : Restart all services:
\n$ $COMMON_TOP\/admin\/scripts\/<context_name>\/adstrtal.sh APPS\/<APPS password><\/p>\n

Restoring the AutoConfig updated files and restarting the services allows you to log on to OAM.<\/p>\n


\nRestoring the previous configuration <\/u><\/strong><\/p>\n

Now we run OAM AutoConfig to restore the Applications Context.<\/p>\n

Step 1<\/strong> :Log on to the Oracle Application Manager (OAM) & click site map.You will be able to log on but some services will be down.
\nStep 2<\/strong>: Click AutoConfig from the list of System Configuration features in the Administration tab.
\nStep 3<\/strong> : Click the Show History button for the application tier context file to access the Context File History page.
\nStep 4<\/strong> :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.
\nStep 5<\/strong> :Save & respond the tabs. Log out of OAM.
\nStep 6<\/strong> :Shut down all services:
\n$ cd $COMMON_TOP\/admin\/scripts\/<context_name>
\n$ adstpall.sh APPS\/<APPS password>
\nStep 7 <\/strong>:Run the AutoConfig script, adautocfg.sh & Respond to the prompts.
\nStep 8<\/strong> : View the log file and check for any errors.
\nStep 9 <\/strong>: Restart all services:
\n$ $COMMON_TOP\/admin\/scripts\/<context_name>\/adstrtal.sh APPS\/<APPS password>
\nStep 10 <\/strong>:Log on to the Oracle Application Manager (OAM)<\/p>\n

If the status of some services appears to be down, click the Refresh icon to update the
\nstatus.<\/p>\n
