Log on to the database/applications server, and run the following UNIX commands…

cd $ADMIN_SCRIPTS_HOME
adapcctl.sh stop; adoacorectl.sh stop;
adoacorectl.sh start; adapcctl.sh start;

Or, without changing directory…

$ADMIN_SCRIPTS_HOME/adapcctl.sh stop; $ADMIN_SCRIPTS_HOME/adoacorectl.sh stop;
$ADMIN_SCRIPTS_HOME/adoacorectl.sh start; $ADMIN_SCRIPTS_HOME/adapcctl.sh start;

Alternatively, the entire Applications tier can be stopped and re-started using the following two commands (the APPS username and password must be provided)…

$ADMIN_SCRIPTS_HOME/adstpall.sh
$ADMIN_SCRIPTS_HOME/adstrtal.sh

Note: after stopping the applications, make sure that the FNDSM (Service Manager) process has finished before re-starting:

ps -fu $LOGNAME | grep FNDSM
