Beer. It was too late to find empty space on The Oak Table for my laptop, but there was always a router and a cable so the laptop was put on the lap. And Johannes registered oaktable.net. That was a really fantastic thing. <br /><br />Yes, it was great, Cary, but it isn't coming back. Grandchildren and pension funds grow, mortgages and time to retirement shrink. It is not only that the zoom table network appears much less attractive than the one from solid oak, but neither the individuals who were there nor the world around them have stayed the same. There are more important things than spending hours in an airplane just to meet, drink beer and discuss wait events. Let us remember and tell all the anecdotes to those who want to listen.<br /><br />In many ways, we are of course still the same people, and many of us hopefully still have the same way of approaching things and doing things. The same craziness if you like. Find something else to be crazy about. I have, and I'm happy.<br /><br />/BjørnBjørn Kisbye Engsighttps://www.blogger.com/profile/05559476096132370853noreply@blogger.comtag:blogger.com,1999:blog-2954359812249072053.post-17455251428190673052021-10-01T17:10:34.969-05:002021-10-01T17:10:34.969-05:00This is most excellent news, cannot wait for the n...This is most excellent news, cannot wait for the new book.

The OS call I’ve seen related to <i>enqueue</i> events is <i>semtimedop</i>. If you look at the manual page for <i>semtimedop</i>, I think it will make sense to you what is going on.Cary Millsaphttps://www.blogger.com/profile/16697498718050285274noreply@blogger.comtag:blogger.com,1999:blog-2954359812249072053.post-75493884587913367472020-01-20T08:08:31.001-06:002020-01-20T08:08:31.001-06:00Cary , one question.

Which Cary sometimes does, for example in the analysis of the pros and cons of the waterfall method versus the agile method.<br /><br />I will claim that I used both methodology and method in a boringly accurate way in this post.<br /><br />I very rarely do also engage in methodology while I always cringe when someone calls a method a methodology.<br /><br />mwf<br />Mark W.

You collect your AWR and pull your trusty ASH routines off the shelf and ..... NADA. They don't help show that active user wall clock time, in the middle of processing, was being spent outside of Oracle. ASH misses it and has "black hole" gaps in the collection effort because Oracle categorizes SNMBFC as an "Idle Wait State" and a NON ACTIVE session. You have to "flip" underscore init.ora parms to overcome this annoyance in ASH, but getting a wait states trace "tells the story" that ASH totally misses by default.MSanchezhttps://www.blogger.com/profile/04564928966813364324noreply@blogger.comtag:blogger.com,1999:blog-2954359812249072053.post-55051649056240399842017-11-27T15:06:18.904-06:002017-11-27T15:06:18.904-06:00Colin, thank you.
