Step By Step Distributed Installation on SAP- Part 1

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.Distributed ABAP+Java System.pngAdditional Application Server Instance for a Distributed System.PNG

      Could you please show me the profiles in you RZ10 dropdown OR the profiles on your /sapmnt/SID/profile directory? I only need to see the file names, NOT the content.
