1. Open a new terminal window and setup environment to run scripts on Application Tier (for more info see How to setup environment for Application Tier at linux terminal?)

2. Start the Application tier

cd $INST_TOP/admin/scripts

./adstrtal.sh

If you don't know what is the directory for $INST_TOP then use the following:

cd /u01/apps/[hostname]/inst/apps/[SID]_[hostname]/admin/scripts

./adstrtal.sh

It will ask you to provide APPS user DB password

3. Once you give above information, all services in application tier will start automatically.

4. To confirm the status of services, use OPMN (Oracle Process Monitor and Notification control)

adopmnctl.sh status

It will give you an output such as this:

Processes in Instance: [SID]_[hostname].[domainname]
---------------------------------+--------------------+---------+---------
ias-component                    | process-type       |     pid | status  
---------------------------------+--------------------+---------+---------
OC4JGroup:default_group          | OC4J:oafm          |   25098 | Alive   
OC4JGroup:default_group          | OC4J:forms         |   25023 | Alive   
OC4JGroup:default_group          | OC4J:oacore        |   24875 | Alive   
HTTP_Server                      | HTTP_Server        |   24818 | Alive
