This year I will be presenting in OOW again. It will be my first presentation in OOW as an Oracle ACED. My first session will be on using Oracle 11g RAC, Linux, and Infiniband technologies in consolidating your data center. This year, one of the largest telecommunication technologies companies of Europe has implemented a 6 node RAC (144 Intel cores, 768 GB memory, with ~25TB storage) in order to increase its overall data center utilization and decrease its administration costs.
In this session of “allinone” cluster, you will be hearing how we have achieved more with less effort by moving more than 17 different single instance databases over this commodity Oracle RAC environment. Here are some questions I will be trying to answer throughout the session :
- Why do you need consolidation (Do you ?) ?
- How to architect such a system ?
- Why to bother about Infiniband for such a large implementation ?
- Why ASM is a must for such a large implementation ?
- How to standardize backups, init.ora, and grid environment management ?
- Why separation of Linux users for CRS,ASM,etc is critical ?
- And many others…
Let’s meet with the youngest Oracle ACE Director in Open World @ session S307853.
For other sessions given by other ACEDs refer to OTN TechBlog.
Since 2006 I haven’t been developing by using Oracle APEX. As far as I remember version was 1.5 or 1.6 at that time. In time, I heard lots of great things about APEX from many people (maybe the most important one is Tonguc). So I have decided to attend Oracle Application Express 4.0 sessions at ODTUG this year. As Oracle guys have mentioned in their presentations, I will also stress that the things written in this post is just reflecting a direction. No promise that you will find all in the production release. So, here are the list of a few things thought to be available by APEX 4.0
Easy Way to Develope : Web Sheets
Even for simple form & report based applications (acutally it is a much general problem) the major problem is that users always ask for something different from what developers put on.It seems that Oracle APEX development will be possible by the actual users of the applications in the near future. With Web Sheets, Oracle’s aim is to let user to produce his/her own applications on APEX without bothering any developers. Builder and Run Time components of APEX are being merged within Web Sheets to let the development of dirty quick applications by users themselves.
For example, instead of a marketing guy sending a report to a sales guy in an Excel sheet (including some tabular data, charting, may be some input fields, etc in it) attached to an e-mail, he can simply put the report on intranet via an application easily developed on APEX. He or others can add some attachments, tags, comments on some data. Moreover, if the producer of the application or anyone else changes any piece of data, all chages will be audited. Even more they can add some notifications for their reports so that reports can be automatically sent to their e-mail boxes.
Obviously there are some differences in developing a classical APEX application and a Web Sheet. Here are just three differences between an APEX application and a Web Sheet:
|APEX Application||Web Sheets|
|Primary Key Maintenance||Trigger or Sequence||Automatically Managed|
|Page Flow||Controlled by branches||Limited|
|Look & Feel||Themes & templates||Basic Control|
Declarative Way of Scripting : Dynamic Actions
Better Charts : Integration with AnyChart 5.1
When I gave up developing APEX, the only charting option you had was SVG (Support Vector Graphics). It seems that in time Oracle put another option of charting, namely flash charts into APEX. APEX uses the flash charts developed by an Oracle Partner company AnyChart. In version 4.0 the latest version of this charting module (currently 5.1) will be embedded into APEX.
Integration with Other Applications : REST Web Services
It seems that currently APEX does support SOAP Web Service calls from the applications you have built with APEX. By APEX 4.0, Oracle will also allow you to call REST Web services. Besides the architectural differences between a SOAP web service and a REST web service, the list of a few REST web services seems to be very attractive for many applications:
- Yahoo Map
- Google Picasa
- Amazon Products
And in the demo, Oracle guys show that how it is easy to embed a map into your application.
Extensibility : Plug-ins
Due to the fact that it is impossible /impractical to satisfy all individual customer needs, by APEX 4.0 Oracle introduces the concept of plug-in. You will be designing your own plug-ins by using bare PL/SQL APIs and you will be able to use it as an item in your applications and hopefully you will share that item for me (or the rest of the community) to use it. I think this is one of the best features and we will be using very fancy APEX plug-ins developed by many people just like the plug-ins developed for Firefox. In the presentation one classical example of these plugins was demonstrated. That was infamous star rating plugin
Finally, I am pretty sure that there will be many more in APEX 4.0 when it becomes available. So hope to return back to development some day and meet with APEX 10.0 at that time J
After a long trip to San Jose (around 24 hours :)), today we have ride to Monterey with my friend Anil. Monterey is a very quite, beautiful city near by the ocean. Although it is in June, Monterey was extremely cold today. We have walked on the sand at sea shore, eat something in a fish restaurant and walk around the city town.
Our hotel Montery Hyatt Regency is one of the best hotels I have ever been. Nice green golf fields, quite environment, and smiling face staff (Thanks Joe for your advices about the down town).
3 hours ago, I have woke up for a phone call (at 2 am in the morning). And my manager was on the phone asking for help on one of the systems I have recently engineered. After solving the problem in the RAC cluster, I had started to write to share my tomorrow (Sunday) program in Kaleidoscope. It seems that I will be attending to APEX stream for whole day. Especially I am curios about following sessions:
- Keynot Session by Joel Kalman, Oracle Corp
- Leveraging Oracle 10gXE, APEX, and SQL*Developer to Build an MDM Solution by Shravan Kumar, APEXor
- APEX Panel Discussion
See you in Kaleidoscope Day 1
