In this article I’ll show you step by step SAP installation procedure “How to install SAP Central Instance on Windows environment”.
Actually the steps to install SAP Central Instance is exactly the same as to install SAP Dialog Instance. The difference is there’s no question screen about Dialog Instance data.
One part of SAP Basis Consultant tasks is to prepare SAP System landscape from the beginning. You will do your SAP installation from Database Software Instance (Oracle/MS-SQL/DB2/MAXDB), Central Instance (CI), SAP Database Instance and additional Dialog Instance.
After you finish SAP CI installation you can add some additional SAP Application servers that serve as additional SAP Dialog Instance. Before you do the installation you have to make your server meet SAP Hardware Requirement. Detail about system requirements for SAP installation is provided in SAP installation guide (you can find in service.sap.com/instguides, user and password is required)
Please prepare the following SAP software CD’s before doing the installation:
1. SAP Installation Master
2. SAP Kernel
3. SAP Oracle Client
Don’t forget to read your SAP installation guide as your main guidance.
PREREQUISITE:
Set your JAVA_HOME first in your environment, point to your Java Directory.
Example: JAVA_HOME = C:\java
STEP:
1. Put your SAP Installation Master CD in CDROM/DVDROM Drive and run sap installer program SAPINST (usually in folder DRIVE:\IM\SAPINST\NT\, wait until the initial screen comes out.
2. Choose “Central Instance Installation” –> Depend on your database and Unicode/Non-Unicode, in this example I use Database Oracle with Non-Unicode.
