If you are going to be examining your DASD setup, check to see if you have your file systes striped. I did a few tests here and saw performance increase about 10% when I striped the file systems. You have to weigh this against the fact that you can not dynamically extend a striped file system, though; you have to back it up, delete it, recreate it, and restore.
Jon <snip> Alan Altmark pointed us a good site with lot of tuning tips for zLinux. We discovered that our DASD was poorly configured, because we didn't split our addresses among more than one LCUs on the Sharks. Having addresses 2000-2017 configured and used for DB2 is the worst setup we could have conceived. We expect to gain better I/O once the DASD will be conveniently setup. </snip> ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
