Creating Weblogic Domain for Fusion Middleware

After we have installed the Fusion Middleware and completed its initial configuration, next step is to configure a weblogic domain. A weblogic domain is a logically related group of weblogic resources. Once we create a domain, and Administration Server instance is also gets created that is used to manage this domain. After this, we can add Managed Servers using this Administration Server by logging into the Administration Server using an admin user account through a console. Web Applications are then deployed on to the managed server(s). We can create multiple managed servers to work as a cluster for load balancing and fault tolerance

ORA-02095: specified initialization parameter cannot be modified

This is a generic error message that may be returned while setting an initialization parameter. There are a few other error messages that we may face and in this article, I would discuss those error messages as well. The most common reason of this error message is modifying a parameter using ALTER SYSTEM command that is not dynamically modifiable. In this case, we need to set the parameter in spfile, or pfile, and then a re-bounce of the instance would set the value of this parameter in the instance.
