Thanks Enrico . Apart from ZOS there might be some more points which makes DB2 to be used in mainframes. If you are aware of them could you please share the same .

around here mainframe implies a zOS operating system

DB2 itself is supported on many operating systems

so the chain is

hardware architecture/platform ( general sense )
operating system zOS,LINUX,zLINUX,SOLARIS,zVM
software chose one

so at the end given a supported combination the choice is company dependent
why software is not available on different combinations of platforms/operating systems
is a marketing concern of the software companies!

the issue is not related to db2 only !

Hello,

The biggest reason DB2 is used on the mainframe is because it is the IBM product. If IBM was the author of Oracle and DB2 was provided by some other vendor, you would be using Oracle. . . The best senior IT executiveonce told me "No manager gets fired for choosing IBM".

Indeed, if DB2 was NOT the IBM stratigic database product, it would have been removed from the market many years ago. Now it will probably be here "forever".
