Hi Arndt,
I am responsible for database administration of ADABAS and IMS on our IBM ES9000/830 mainframe and for our Oracle databases are on a Sun Sparc Center 2000, 4CPU server. For decision support applications with large databases there is quite a difference in performance between the mainframe and the Unix server but not in the direction you might expect. Performance is considerably BETTER on the Unix databases. These are large databases. One application has 75 million rows of data in 22 tables for about 20GBytes of data. Comparable size databases are on ADABAS on the mainframe which we have used for performance comparison.
We have just begun development of OLTP applications with Oracle so I have no performance comparison for that type of work.
Hope this helps.
