How to install SAP Database Instance

After you finish SAP Oracle Database Instance installation and SAP Central Instance installation, now you’re ready to continue to the core installation of R/3 system, that is SAP Database Instance installation.

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 http://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
4. SAP Database Export CDs.

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 “Database Instance Installation” –> Depend on your database and Unicode/Non-Unicode, in this example I use SAP R/3 4.7 Ext2 SR1 on Database Oracle with Non-Unicode. (The installation step for newer version such ERP ECC 6.0 is quite the same, but there’s additional question Solman Key, I’ll show you on next article).
