• Add the following entries into /home/weblogic/.bash_profile file:
• export MW_HOME=/app/Oracle/Middleware/Oracle_Home/
• export WLS_HOME="${MW_HOME}/wlserver"
• export WL_HOME="${WLS_HOME}"
• # Set to appropriate JAVA_HOME.
• export JAVA_HOME=/usr/java/jdk1.8.0_91
• export JAVA_OPTIONS="-Djava.security.egd=file:/dev/./urandom"
• PATH=$PATH:$HOME/bin:$JAVA_HOME/bin

• Give the Domain path as /app/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/ 
• and select all default options except selecting the "Production Mode" when asked for installation mode to have run Weblogic in production licensed mode
• Provide Username password as "weblogic:Weblogic123"
• Finish Domain Creation Wizard and come out of (exit) VNC Client
• Start NodeManager and Admin Server
• Login to Machine via SSH Client
• Switch to weblogic user
• $su - weblogic
• Start NodeManager
• $cd /app/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain
• $nohup ./bin/startNodeManager.sh &
• Verify at nohup.out log for successful start of NodeManager.
• In case any issues you face with startup please check if hostname and ports and secureLister=false are correctly configured in nodemanager.properties file
• /app/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/nodemanager/nodemanager.properties
• ****Note that we have installed Weblogic with Production Mode which requires username and password to be entered while starting the servers to by pass username and password ask and start server in backrgound***
• Manully create boot.properties for Admin Server
• $cd /app/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/servers/AdminServer
• $mkdir scecurity
• $cd security
• $vi boot.properties with following values
• username=weblogic
• password=Webloigc123
• Start Weblogic Server
• $cd /app/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/bin
• $nohup ./startWebLogic.sh &
• Open web browser and hit the URL "http://<HOST-NAME>:7001/console/login/LoginForm.jsp" and enter credentials as "weblogic/Weblogic123"
• If you are able to see the login page and login, it confirms installation is successful

• In the general tab, select "<HOST-NAME>" in the Machine drop-down box, disable "SSL Listen Port Enabled" and Click Save.
• In the Server Start tab, ether the following information and click save
• Java Home as "/usr/java/jdk1.8.0_91/"
• Java Vendor as "Oracle"
• Arguments as 
• -Xms1024m -Xmx3076m -Djava.library.path=/app/Oracle/Middleware/Oracle_Home/wlserver/server/native/linux/x86_64/
• Start Server-1
• Select from left tree "base_domain -> Enviornment -> Servers" and then select Server-1 and start
