Oracle Advanced Queuing and JMS – bridging from AQ to JMS and vice versa
0In preparation for our Oracle Open World session ‘Xenogenetics for PL/SQ – Infusing with Java Best Practices and Design Patterns’ – I have been doing a little work on Advanced Queuing in the Oracle RDBMS, as well as on Java Stored Procedures. The objective of this presentation is to bring best practices, design patterns as well as new functionality to the world of PL/SQL from other worlds, such as Java. Interaction between database applications and the rest of the world is an important part of that. And such interaction, especially when we have a need for decoupled interaction, which we frequently should have, Advanced Queues will be used at the database end to support that interaction.
The concept of queuing – and more generally: messaging – has its Java counterpart in JMS, the Java Message Service. The question I then asked myself is: how exactly can I map AQ to JMS and how can I link the two worlds. How can I expose the AQ Queue or Topic in the RDBMS as a JMS Queue or Topic? And how can I consume messages from JMS into the database, possibly to AQ?
One of my reasons for making the connection between AQ and JMS has to do with another presentation at OOW I will deliver, More >
Event based Decoupling in PL/SQL – your first Advanced Queue adventure
1Back in 2004 when we started with the AMIS Technology Blog, my main objective was to record the things I infrequently do in order to have notes describing the steps to go through whenever I needed to do the thing again. I was own primary audience, so to say. Over the years, the articles have increased in complexity and sometimes in absurdity too. This one is back to that original intention. This article is not fancy at all – even though it touches upon a powerful (and underrated) subject: the Advanced Queue in the Oracle RDBMS. For the 1000s of database developers and architects that make frequent use of AQ, I am not going to add anything: this article merely shows the steps for creating an Advanced Queue, how to register a listener on the queue and how to publish a message on the queue. That is not fancy at all, obviously.
What is extremely fancy and powerful – and not nearly used enough – is the architectural pattern that AQ allows us to introduce. Queues are a key concept for achieving decoupling. Decoupling itself is like the holy grail of architects – because it allows agility and reuse. Through a Queue, a publisher (or discoverer) of events can make them available to More >
Laatste "Plug" – Cuddly Toys Not Included – Een AMIS Query met Doug Burns
2Donderdag as. is de AMIS Query van Doug Burns over SQL Tuning, gebruikmakend van de Oracle Enterprise Manager (Tuning en Diagnostics pack). Misschien verwachten velen een hoog “DBA” gehalte, maar niets is minder waar…
Deze presentatie bevat bijna geen enkele slides en is echt een aanrader om bij te wonen. Het gaat over kleuren, indelingen, interpretaties van grafieken en er zit een goeie scheut droge Schotse humor in deze presentatie verwerkt. Waarschijnlijk zal Doug ook nog de Real Time SQL Monitoring tool in kleur en geur uitleggen.
Met andere woorden geen moeilijke “DBA” achtige presentaties, maar stof om over na te denken als het gaat over SQL Tuning en de tooling, De Oracle Enterprise Manager (de bij de database meegeleverde DB Console) in dit geval de Oracle 11gR2 variant, die Oracle hiervoor steeds meer navoren drukt op alle mogelijke tiers waar zich Oracle en andere software bevind.
Voor extra info over Real Time SQL Monitoring zie ook de volgende blogpost: Real Time SQL Monitoring
Het is nog mogelijk om je aan te melden (zodat we o.a. een inschatting hebben t.a.v. de hoeveelheid eten) voor deze AMIS Query op Donderdag 17e Juni om 18:00 uur via:
An Evening with Oracle Database Security Expert: Pete Finnigan
1AMIS Technology School is proud to present, in collaboration with Miracle Benelux Masterclasses:
- An Evening with Oracle Database Security Expert: Pete Finnigan on Tuesday 25th of May, 2010.
Miracle Benelux and Pete Finnigan agreed to do an extra special on the AMIS premises the evening just before Pete’s 2 day Masterclass in Utrecht will start (for the 2 day Masterclass agenda, see also the following URL). During this AMIS Query, besides the free food and normal standard setup of such an AMIS Query Event, Pete will have a presentation on Oracle security and there will be a lot of room of informal discussions during and after this session. There is still some room if you would like to learn from one of the best on Oracle database security.
More details on those masterclasses can be found on the Miracle Benelux site. Hopefully this will be the first of series… More details about this event will follow shortly.
About Pete Finnigan…Pete is a world renowned expert in the area of Oracle security providing consultancy, design, security audits and trainings all in the area of Oracle Security. Pete is a member of the Oak table network, he has spoken regularly all over the world at More >
Hotsos 2010 – Presenters, Presentations, Presenting
1I 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 >
Hotsos 2010 – About swag, the Oscars and other stuff
0Its Sunday and its raining outside. The nice weather on Saturday (approx. sunny / 20 degrees Celsius) has gone. After a decent flight on Friday where I actually made it to switch in Houston from the international Continental flight, going through customs and pick the next one, a domestic Continental Express flight, within the boundaries of 1 and 1/2 hour. I was so fast that switching for one flight to the other, that apparently my luggage didn’t manage to travel with the last flight. So after I found out that my luggage was still somewhere in Houston, I got from Dallas Love Field to the Omni Hotel in Las Colinas, Irving, where the Hotsos conference will be held again. The whole area is a bit in shambles because they are rebuilding a lot of the environment. While getting to the Grapevine Mills mall yesterday, I noticed that they also a building a new Irving Convention Center along the highway. Another addition to the already crowded Dallas/Plano/Irving Metroplex.
