i just want to explain the question in a better way..
In LUW(Linux.unix windows) for DB2,
We call instance as an environment where we have database and the background process along with the storage area declared for the same.
In Z/os (DB2)
Instance is replaced by Subsystem in Z/os.
Subsystem is nothing but collection of tasks or services which is performed in different address space or memeory area
1)If i need to create a new subssytem whetehr i need to declare a new storage area i.e a new address space or a new area has to be allocated?
2)AS like in instance in LUW whether we can have more than one databse in subsystem in z/os?
Please let me know if u have any doc having diff between Instance in LUW and Subsystem in z/os
