I was lucky enough to get my hands on the Method-R Profiler and had a test drive with it. So first of all what is it? As you might expect a profiler, a profiler for Oracle performance problems. The tool makes use of Oracle’s trace facilities. If you have a performance problem with the database or a specific issue in you code, you are able to set a specific part of your code, or if must be, the whole database in trace mode. The database will write the output of your trace to the UDUMP, user dump, destination or in the trace directory of your database diagnostic section on the database server, depending on your database version.Consistent Analysis
Pete Finnigan has a nice post about how you can achieve this called “How to set trace for others sessions, for your own session and at instance level“. As also is mentioned in this post, the Oracle TKPROF tool can be used to analyze the generated trace files. One of the disadvantages, IMHO, is that if you give such a TKPROF generated report to, lets say 10 Oracle (DBA) performance interested people, you will get afterwards 10 different analyses regarding what is reported in those reports. This is, among others, also caused by the fact More >
Currently in Cary Millsap’s session about his agile approach on things called “My Case for Agile Methods“. Agile is (not yet) my thing, but knowing Cary, and he is in to it, when he is enthusiastic about something its probably one of those things which you should look into. If not even due to, as far as I know, the Agile context Cary is using is not the Agile context referred to I see being used out there. The “agile” thing out there is the one, is the one, I will joke about. But that said, a lot of methods are not bad at all, but people implement them wrongly so trying to keep an open mind, this session of Cary was more or less mandatory to get my vision about this back on track once more.
Cary also mentioned this emotion that probably mainly goes around in the DBA world. But as Cary mentioned during his presentation, “Agile is not undisciplined”, so if it gets the wrong emotional context, then is mainly due to people not doing it correctly. Could be thats it has to do with not being correctly trained in Agile or maybe incorrectly “managed”. So what is Cary’s feeling about this, that is, “Agile” as is…
I never find it very easy to try to capture the atmosphere during a conference, the presenting part, the presentations or the discussions, for example, you could have with the presenters. Hotsos is such a cool and unique event were you have the opportunity, to listen but also to interact. The amount of people that attend isn’t that big, only a few hundreds, but they share all the same passion, the passion to improve on performance, mostly Oracle related. It has only two tracks and its not uncommon that people present and than go afterwards to a presentation to listen in what the other presenter has to say.
Due to the fact that it is manageable in terms of choice, located on a convenient location and well organized, you have the opportunity to pick just the thing you like and most of the time not miss out on “the other” presentation you would have liked to see. Besides that people stay in (overnight in the Hotel), so discussions about the technology, the method or an example during a presentation will be discussed in far more detail than you normally would do, from presenter to presenter or from presenter to the guy that attended and vice versa. The fact that all have the passion More >
