Hi
i just clarified my doubt in central instance !!1
Can any one tell what is database instance ?
Regards
sanjeev
Okay now,
When you install SAP, It prompts you to provide a System Id which is called SID, that is recognized by the system, Since for any SAP installation you must have a Database, It requires you to provide an identification for the Data base also. For Eg: If you are installing Nw04s with MAXDB as a database, you would give the SID as J2E and Data base ID also as J2E so that there is no confusion...

Hi
The database instance is a mandatory instance for the installation of an SAP system. The SAP system usage types AS ABAP and AS Java use their own database schema in the same database.It contains all the database related services.
You have a database now sap instance creates a schema on that database and uses this schema for its operations.

Hello Manu,
I don't agree with you.
Central Instance is NOT always database instance.
Database may NOT always reside on Central instance.
"Instance on which Database resides is a database instance"

Hi,
