@ balu . the dialog instance is used to maintain load on the server. if there are many users additionally adding on a server we need to provide them with additional work processes. hence a dialog instance is connected parallely to a central instance but the database in dialog instance is pointed to the central instance only. in each dialog instances the resources of the system r used to increase the work processes. the dialog instance does not contain message server , gateway server and enque server. it can only handle dialog , background and update work processes.

Dialog instance is mainly used for load balncing, Initially Sap system is installed on Central instance later on to balance load we install dialog instance. Central instance communicate with DI via message server through ABAP dispatcher. DI doesnt contain message and enque server.
