Register or de-register the Oracle Web Tier with the Oracle Weblogic Domain

Once an Oracle WebLogic domain has been created, the Oracle web tier can be linked to the domain. The advantages of doing this are that the Oracle web tier can be managed and monitored via the Oracle Fusion Middleware console.
1.      To register the Oracle web tier with the WebLogic domain, execute the following commands  on each web tier instance.
cd <ORACLE_WT_HOME>/instances/instance_name/bin
./opmnctl registerinstance -adminHost <hostname> -adminPort <adminport> -adminUsername Weblogic
<Enter the Weblogic password when prompted>
2.      To de-register the Oracle web tier with the WebLogic domain, execute the following commands on each web tier instance. 
cd <ORACLE_WT_HOME>/instances/instance_name/bin
./opmnctl unregisterinstance -adminHost <hostname> -adminPort <adminport> -adminUsername Weblogic
<Enter the Weblogic password when prompted>
Note: Ensure the weblogic admin server is running while registering or de-registering !
