By Stephen Ciullo, HP Senior Technical Consultant and Doug Grumann, HP System Performance tools expert revision 10JUN09
Have you ever run across a document that sounded really interesting and useful, but after a short while you found out it was several years old and horribly outdated? Well, if you are reading this revision of the Performance Cookbook in 2015, then go no further. By
2015 this paper will be obsolete because all systems will tune themselves using ROI- regeneration beams anyways. If, however, if it’s more like 2009 or 2010, then you are in luck: you have stumbled across an old document, but we have managed to update it and keep it (relatively) current! For those of you who have studiously studied the 2008 revision of this cookbook, we have some more good news for 2009: there are not a whole lotta changes in this rev so your knowledge has not become obsolete. We have added a few tidbits about disk I/O, a “gotcha” with regards to memory metrics, and clarified the
NUMA/Oracle discussion, but generally the principles outlined here seem to have withstood the test of time.
As with previous releases of the cookbook, note that:
- We’re not diving down to nitty gritty detail on any one topic of performance. Entire books have been written on topics such as SAP, Java and Oracle performance. This cookbook is an overview, based on common problems we see our customers hitting across a broad array of environments.
- We continue to take great liberties with the English language. To those of you who know English as a second language, we can only apologize in advance, and give you permission to skip over the parts where Stephen’s New Jersey accent gets too thick.
- If you are looking for a professional, inoffensive, reverent, sanitized, Corporate- approved and politically correct document, then read no further. Instead, contact your official HP Support Representative to submit an Enhancement Request. They
