INSTANCE_NAME In a Real Application Clusters environment, multiple instances can be associated with a single database service. Clients can override Oracle's connection load balancing by specifying a particular instance by which to connect to the database. INSTANCE_NAME specifies the unique name of this instance. In a single-instance database system, the instance name is usually the same as the database name.

Object-oriented programming concepts: Objects and classes An instance is a specific object built from a specific class. It is assigned to a reference variable that is used to access all of the instance's properties and methods. When you make a new instance the process is called instantiation and is typically done using the new keyword.

What are the differences between instance methods and class methods? Instance methods of the class can also not be called from within a class method unless they are being called on an instance of that class. Instance methods. on the other hand require an instance of the class to exist before they can be called, so an instance of a class needs to be created by using the new keyword.

- Instead of accessing class member variables directly, you define get methods to access these variables, and set methods to modify them. By encapsulating them in this manner, you have control over the public interface, should you need to change the inner workings of the class in the future.his answer is merged from another question. Your getAge() method is called instance method in Java. To invoke an instance method, you should have a object of the Class in which this method is defined.

Objects, Instance Methods, and Instance Variables An object that is created using a class is said to be an instance of that class. We will sometimes say that the object belongs to the class. The variables that the object contains are called instance variables. The methods (that is, subroutines) that the object contains are called instance methods.

- When the compiler generates an instance initialization method, it bases it on a constructor. It gives the method the same parameter list as the constructor, and it puts the code contained in the constructor's body into the method's body.

- I had this same issue when I was assessing 100+ servers, I had a script written in C# to browse the service names consist of SQL. When instances installed on the server, SQL Server adds a service for each instance with service name. It may vary for different versions like 2000 to 2008 but for sure there is a service with instance name. I take the service name and obtain instance name from the service name.

Rename a Computer that Hosts a Stand-Alone Instance of SQL Server The following steps cannot be used to rename an instance of SQL Server. They can be used only to rename the part of the instance name that corresponds to the computer name. For example, you can change a computer named MB1 that hosts an instance of SQL Server named Instance1 to another name, such as MB2. However, the instance part of the name, Instance1, will remain unchanged. In this example, the \\ComputerName\InstanceName would be changed from \\MB1\Instance1 to \\MB2\Instance1.

- An update to the above answers, I agree instance methods use an instance of a class, whereas a class method can be used with just the class name. There is NO more any difference between instance method & class method after automatic reference counting came to existence in Objective-C.

instanceof : Java Glossary Implementation. It turns out that everything depends on the type of the desired instance and the actual type of the object. The type of the object’s reference is irrelevant, though obviously it could be used to optimise away silly instanceofs such as Dog instanceof Dog.

What is the difference between class object and class instance? Class variables only have one copy that is shared by all the different objects of a class, whereas every object has it’s own personal copy of an instance variable. So, instance variables across different objects can have different values whereas class variables across different objects can have only one value.
