One of the Features in Oracle Applications R12 is we can enable Maintenance Mode in Business Suite with downtime and the  web redirection to prevent user access to the system. The purpose of the configuration is users  can know the downtime for the application when we performing the maintance activity.

By doing the following tasks we can achieve the downtime url which will show the users Maintenance task message  when  Apache is in restricted mode.

Step1: Schedule a downtime using OAM (Oracle Application Manager)

Click On OAM> Site Map / Maintenance Tab / Manage Downtime Schedules

Step2: Enter the scheduled timing details and submit the form

txkrun.pl  -script=ChangeApacheMode -contextfile=/d02/testapps/TEST/inst/apps/TEST_test/appl/admin/TEST_test.xml -mode=Restrict

Step8: Start Oracle HTTP Server and oacore OC4J should you need to monitor the system

From now on, all access to e-biz will be redirected to the downtime page which is mentioned the page in Step 4.

            sh adapcctl.sh start

            sh adoacorectl.sh start

Once the maintenance is complete, switch the system back to normal mode by using the following steps

Step:9: Run the script for putting the Apache in Normal Mode

txkrun.pl -script=ChangeApacheMode -contextfile=<Path to the Context File> -mode=Normal 

txkrun.pl -script=ChangeApacheMode -contextfile=/d02/testapps/TEST/inst/apps/TEST_test/appl/admin/TEST_test.xml -mode= Normal
