Hi All,
As we all know we can install a SAP system with below option.
1. Standard system
2. Distributed system and,
3. High Availability System
Here, I am writing about Distributed system installation.
Overview:
An SAP system consists of SAP instances. An SAP instance is a group of processes that are started and stopped at the same time.
In a distributed system, every instance can run on a separate host.
A distributed system consists of the following instances:
- ABAP Central services instance (ASCS instance)
- Central services instance (SCS instance)
- Database instance (DB)
The ABAP stack and the Java stack use their own database schema in the same database.
- Primary application server instance (PAS)
Optionally you can install one or more additional application server instances.
