I'll add also that Oracle on Linux for 390/Z benefits a lot from as much mdisk cache as you can reasonably give it, especially with large databases, as it allows you to keep the virtual machine size small (important for good behavior) but still do a fair amount of I/O avoidance. If you're running in 64-bit mode, you may still want to define some XSTOR to work with the mdisk cache.
Jim's comment is very true wrt to it being the same product as on other platforms. The utilities have the same bugs as well -- one thing we tripped over at one customer was reloading a multivolume tape set from another platform into Oracle on Z didn't work due to a bug with the database dump/restore utility. I think it has been fixed by now, but you should be certain to apply all the maintenance to avoid problems like that. As far as better/worse -- well, it's no better or no worse than Oracle on any other platform. Careful tuning (of VM size & Oracle parms) is still required (and in fact, is a lot more important here than on systems with CPU to burn). -- db David Boyes Sine Nomine Associates > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED]]On > Behalf Of Jim > Rich > Sent: Thursday, January 02, 2003 12:17 PM > To: [EMAIL PROTECTED] > Subject: Re: Oracle 9i > > > Our developers and database people find Oracle9i on Linux/390 to be > identical to Oracle9i > on any other Unix or Linux box.
