11i Stop/Start Oracle application Server

First Make sure that the database and listener are up and running before starting application services.
Database and listener should be down after all application services are down.

Application scripts should be placed in COMMON_TOP in 11i.

the default location for this scripts are : $COMMON_TOP/admin/scripts/$CONTEXT_NAME,


the fallowing scripts should be used for starting and stopping all application services

adstrtal.sh,---- to start

syntax:
adstrtal.sh apps/apps_password

adstpall.sh----- to stop

syntax:
adstpall.sh apps/apps_password

apart form this scripts there individual scripts for all application services. Not all customers use all components of oracle applications some services of oracle  application like discoverer,icx bulk loader etc are not used by all customers. adstrtal.sh&adstpall.sh scripts intelligent enough to start only required services. Basically it reads $CONTEXT_FILE (xml file) to know what all components are enabled for that particular node of application instance.

Server process:

Form Sever Listener                                                                    adfrmctl.sh
Start the Forms Server processes

Form Metric Server                                                                     adfmsctl.sh

the given pool.

Form Metric Client                                                                       adfmcctl.sh

Sends load information, such as the number of forms processes that are currently

running on that machine, to the Metric Server. The Metric Client runs on each machine

with a forms server.

Report review agent/Apps listener                                             adalnctl.sh

Used to view concurrent processing files online. This utility uses Net services to

communicate with form server.

Java process that services one_to_one fulfillment requests for distributing collateral

Note :

For concurrent processing server its must and should we have to start apps listener
first, but for down concurrent processing server any way we can do.
