I'm just finishing up a cost case for a similar environment, and the numbers look very good if you can live with some of the technical restrictions. As others have said, there are limits on the size of the databases supported by UDB, however with the ability to run multiple copies of UDB in the VM system, this is not necessarily a show-stopper if you distribute individual tables to separate databases. The setup for DRDA over TCP is pretty straightforward, and the use of hipersockets is actually a very nice setup for this type of operation.
The cost savings is pretty dramatic -- in the case I'm working on, reducing the size of a z/OS partion by 1 standard engine and enabling similar workloads on 2 new IFLs reaps a cool $350K savings in the first year (by the time you include the reduction in z/OS licensing and the corresponding reduction in ISV prices for a smaller z/OS machine footprint, you're talking about real money). Is it technically perfect? Not yet. Still, $350K/yr will buy a lot of remediation for the current problems. -- db David Boyes Sine Nomine Associates > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Dave Jousma > Sent: Thursday, April 03, 2003 2:34 PM > To: [EMAIL PROTECTED] > Subject: Thoughts on DB2... > > > All, > > On our traditional mainframe system, we are running a > z/800-001 that is > maxed out on CPU.
