Now for a dialog instance. If you want to distribute a system landscape across multiple servers, you require a central instance on a server and, on every other server, a dialog instance with a dispatcher and server in which you can then create additional server processes. Dialog instances are installed on application servers. The dialog instances of a Java system are called Java dialog instances.
Dialog instances are SAP instances that include only:
- Dispatcher, IGS and CCMS agents
- Java and Java Add-In system: Java server processes
- ABAP and Java Add-In system: Gateway and certain ABAP work processes (dialog, batch, spool, or update)
