Wanna be a hero?

Turn on the 'performance adjustment' - some admins with experience on older versions of OS/400 turn this off (it used to be really bad). To turn it on, use: wrksysval qpfradj and select '3' (automatic adjustment). If you don't want to turn on the performance adjustment, memory pools can be adjusted manually with wrksyssts - use f11 for different views. I've seen the performance adjustment (post v4 OS/400, anyway) make dramatic performance gains, though...

Post #70,003 by imric 12/19/02 6:10:39 PM Reply	chuckle Command names are pieced together from 1, 2, or 3 letter 'pieces' like, wrk for work, sys for system, dsp for display, f, for files, etc. wrksysval actually means "work with system values" dspf means "display file" cpyf is "copy file", etc, etc. As bepatient says, its actually not hard to get used to.

Knowing these guys, I should have prefaced my initial post with "I understand that any host is only as good as its Admin, but, ..." ;-) This is all stuff they know to do, I suppose. But I'd bet not. BTW, a friend of mine that works there just pinged me. He ran a Crystal Report based on a single query with one join. It was some numbers grouped by week over 3 months. The report took 19 hours to run. Now, I know his Sql could be really bad, but 19 hours? <:-O
