StopStartWeblogic.sh

# 1) First step is to sudo as the unix user with weblogic access (replace YOUR_SUDO_USER with yours)
ssh YOUR_USER@YOUR_LINUX_SERVER
sudo su - YOUR_SUDO_USER
# 2) Locate your installed weblogic domain start file
find / -name startManagedWebLogic.sh -type f -print 2>/dev/null 
#or if you use mlocate
locate startManagedWebLogic.sh 
## After a while this command should print something like : 
##/YOUR_SUDO_USER/weblogic/user_projects/domains/YOUR_DOMAIN/bin/startManagedWebLogic.sh

# (Optionnal) set the stopWeblogic.sh to force = true so you don't have to wait endlessly for all activity to be over
vim /YOUR_SUDO_USER/weblogic/user_projects/domains/YOUR_DOMAIN/bin/stopWeblogic.sh
#update this field from echo "shutdown('${SERVER_NAME}', 'Server', ignoreSessions='true')" >> "shutdown-${SERVER_NAME}.py" to 
echo "shutdown('${SERVER_NAME}', 'Server', force="true", ignoreSessions='true')" >> "shutdown-${SERVER_NAME}.py"

# 3) Run to stop a Managed Weblogic Server name YOUR_MANAGED_SERVER : 
nohup ./YOUR_SUDO_USER/weblogic/user_projects/domains/YOUR_DOMAIN/bin/stopManagedWeblogic.sh YOUR_MANAGED_SERVER t3://YOUR_ADMIN_URL:YOUR_ADMIN_PORT >stop_log.out 2>&1 &

# 4) Run to start a Managed Weblogic Server name YOUR_MANAGED_SERVER : 
nohup ./YOUR_SUDO_USER/weblogic/user_projects/domains/YOUR_DOMAIN/bin/startManagedWeblogic.sh YOUR_MANAGED_SERVER t3://YOUR_ADMIN_URL:YOUR_ADMIN_PORT >start_log.out 2>&1 &

## STOP
/YOUR_SUDO_USER/weblogic/user_projects/domains/YOUR_DOMAIN/bin/stopWeblogic.sh
