RE: Record breaking query
Title: RE: Record breaking query I have seen the time for wait_events in 8.1 do funny things when the system date was changed by ntp. Oracle assumes that end time is after start time for each wait event, if this is not the case due to the system clock being changed, you get a BIG number. Every time this happened to us, our firewall (which is the ntp server for all of our other machines) had been rebooted and we saw an ntp event in the system log file. However, we were never able to reproduce this manually. --Michael Brown Glen Raven, Inc./Info ServicesSenior Oracle DBA 1831 N.

RE: Hotsos Clinic 101 Feedback
I've taken it twice (one of the first public classes and again the when they started offering the reduced alumni rate), and stand by my quote on Hotsos's website. "If you have the time to take a class, take the Hotsos Clinic. It was the absolute best performance tuning resource that I have ever invested time in." Of course, I would change "tuning" to "optimization" since we are making tuning a dirty word. For those of you who were not at the Hotsos Symposium in Dallas, you missed a fantastic conference. You should make your plans to be in Las Vegas next year. I am not affiliated in any way with Hotsos, just am impressed by both the knowledge Cary and Jeff have and their ability to convey it to others. -- Michael Brown Glen Raven, Inc./Info Services Senior Oracle DBA 1831 N.

RE: Oracle Licences Req on Intel Xeon CPU
2000 only shows 2 CPUs because it cannot take advantage hyperthreading. >From what I have read (Intel's website, some others), hyperthreading requires both BIOS and OS support to be utilized. Currently, XP and the newer Linux releases are all that I have seen that will take advantage of it. My research on this was fairly light since I was just after can Redhat Advanced Server support it, but I do remember seeing that W2K would not. -- Michael Brown Glen Raven, Inc./Info Services Senior Oracle DBA 1831 N.

The Windows 2000 family counts each hyper thread as 1 CPU. In contrast, Windows XP and Windows 2003 Server count each CPU instead of each hyper thread. Thus, the task manager in Windows XP Professional show 4 CPU's (on a dual XEON CPU computer with hyper threading enabled) while Windows 2000 Professional only shows 2 CPU's in the task manager.

RE: HIT RATIO
What problem? Seriously, the buffer cache hit ratio is a pretty meaningless value (for details on why, see Cary Millsap's papers on www.hotsos.com). Are your users complaining? Are you seeing behavior on the system (disk contention, etc.) that makes you expect that your users will be complaining soon? -- Michael Brown Glen Raven, Inc./Info Services Senior Oracle DBA 1831 N.
