OTN Yathra 2013 – Moving to Hyderabad and Chennai to complete the six-city tour of India
0Yesterday the OTN Yathra visited Bangalore. In the local Oracle office, two rooms were reserved for 14 technical sessions by Oracle ACE Directors, ACEs and other specialists from both India and the rest of the world. The agenda included sessions on Big Data, RAC, EssBase, LDAP (in the Oracle world), SQL, APEX, Database Application Development and Enterprise Performance. 95 Delegates had signed up for this event and many Oracle employees drifted in and out of these sessions as well.
This was the last venue that is visited by the five man band consisting of Edward Roske, Raj Mattamal, Murali Vallath, Hans Forbrich and myself. The last two cities will not have the pleasure of getting visited by Raj or Edward, so this was the perfect opportunity to say a big THANK YOU to the organizer of the tour: Murali Vallath.
Murali put this tour together, soliciting speakers, creating the program, arranging the venues, doing the marketing, finding local volunteers to help put the events together and practical things such as arranging hotels and transportation and liaising with the taxi-drivers as well as staff at local venues.
OTN Yathra 2013 – Spreading the story of Oracle across India – (Half time)
0The OTN Yathra 2013 is taking a group of Oracle ACE Directors across all of India. From New Delhi to Chennai and four cities in between, this AIOUG (All India Oracle User Group) enterprise brings high level Oracle technology content to Oracle developers and database administrators throughout India.
The tour is sponsored by OTN – the Oracle Technoloy Network – and put together by Murali Vallath. At the time of writing, the Yathra has hit Pune, which means that after today we are half way through with Bangalore, Hyderabad and Chennai still to come.
And so far it has been a great experience, for the presenters and I believe for the attendees as well. From the University sites in New Delhi and Mumbai to the ultra modern office of Oracle Financial Services in Pune, our hosts have been wonderful and the audiences appreciative. It is certainly a great pleasure to be in this traveling circus.
The OTN Yathra has at the core speakers on various areas of expertise:
- Edward Roske, USA on ESS Base, Hyperion and many other components in the Oracle Business Intelligence portfolio
- Murali Vallath, India/USA on Database and RAC
- Hans Forbrich, Canada on Oracle Linux, LDAP, Database and several More >
OTN Yathra 2013 – The six city Oracle tour of India
0The Oracle ACE directors and Java champions are organizing an evangelist event called ‘OTNYathra 2013’ between 15th & 27th February 2013. The event is sponsored by the Oracle Technology Network. I will be one of the speakers on this tour – presenting two or three presentations at each of the six host cities for this tour:
Advanced SQL for experienced Oracle developers
Thinking Through Java Enterprise Performance
The very latest in Oracle Database development (including 12c)
Other speakers on this tour will cover topics such as ADF, LDAP, OVM, Oracle Enterprise Linux, RAC and Clusterware, BigData, Essbase and OBIEE, APEX, EPM and Hyperion. Speakers include Java Champion and Oracle ACEs and ACE Directors such as Harshad Oak, Hans Forbrich, Edward Roske, Murali Vallath, Vivek Sharma.
Valuable Java, JavaScript and ADF resources
0In the past few days, I have been working hard on several projects – both ADF and (plain) Java based, with quite a bit of JavaScript involved as well. The three main functional challenges:
- support keyboard (function key based) navigation in rich ADF Web pages (in addition to mouse based actions)
- support online and inline editing of customized (per context) resource bundle entries
- create a stand-alone viewer that allows users to inspect images (jpeg, tiff), PDF documents and Word and Excel documents
While working on these requirements, I have used – through Google, my main tool – a large number of very valuable resources on the internet. From the Oracle Technology Network Forums (OTN) to StackOverflow (http://stackoverflow.com), from personal blogs to corporate white papers as well as formal documentation – I have picked an incredible number of brains in a very condensed period of time.
I did not stop to leave notes of gratitude on all the sites I have come across. So I thought – for my own future reference as well as to pay some hommage to all these sites and individuals that helped me and to provide some insight in what challenges I faced and how I addressed them – to write More >
Oracle E-Learning Resources
2There is a lot of new stuff out there nowadays, regarding products and/or functionality or others. This is also true for Oracle and in short it’s not easy to follow all those innovations and/or new products. So from time to time I have a watch on stuff that interests me on the YouTube Oracle E-Learning Channel. That said, there is just too much out there, which is great, but not so practical to follow via YouTube. Via YouTube you could of course, as I did, create you on channels for specific topics or interests, like my “Oracle – Data Centre Transformation Master Class“, but it can become an annoying bit of doing it especially concerning a topic like “Oracle Enterprise Manager 12c Cloud Control”.
Today, finally also paying attention to the last slide on almost all presentations, I had a look at: http://www.oracle.com/goto/oll . This is the entry page of the Oracle E-Learning group. This link will re-direct you to the central, by Oracle APEX serviced, pages that contain an overview of all the Oracle topics out there, provided via the E-Learning team and believe me, those are great, also one of the reasons I subscribed on their YouTube Channel anyway. I really wished I had done it More >
Implementing Cell Highlighting in ADF 11g RichTables
The Oracle Technology Network just published my two part series on implementing Cell Highlighting in ADF 11g Rich Faces Table components. The articles describe how you can have the end-user set up rules for assigning background colors to the cells in a column, depending on the value in the cell.
The highlighting can be based on thresholds – for example green for salaries under 1200, red for salaries over 3000 and yellow for salaries in between – or on expressions. The latter allows the user to specify one or more logical conditions, using EL syntax and references to the data attributes used in the table; a color is associated with each conditionthe. The first condition satisfied by a row determines its color. For example condition ‘[job]==’MANAGER’ and [sal] < 4000′ (pink) and another condition ‘[hiredate].month < 7 and [deptno] != 30′ (olive).
The article also gives some interesting examples of using some ADF 11g RichFaces features like Popup, programmatic Partial Page Rendering, embedded (region) Bounded Task Flow with input parameters, programmatic EL evaluation, oh eh… and the Color Picker..
