0 0 Why Oracle Forms and BPEL? Old style Forms applications normally don’t hold much workflow functionality. Sure there is an order in which the forms should be used. The workflow of the application is in the mind and knowledge of the user. For my current project I am investigating, together with […]
0 0 You all know the problem. You want to send that large file to someone, but how? Many email systems restrict the maximum attachment size. I have to send large attachments of several hundreds of megabytes to magazines all over the world quite frequently. There are some services that you could […]
0 0 In my previous post about package constants I mentioned the application I am working on right now. They gave me the task to speed up the application since performance was getting worse and worse. I analyzed the statspack results together with a DBA and we found two queries that together […]

0 0 On my recent project we have a large package holding constants values. From a design point of view this is a very elegant solution because this way the constants are all defined in a centralized way. But the usage of this package lead to enormous performance issues. This post tells […]
0 0 I wanted to generate an Excel file with data coming from an Oracle database. One of the best ways to do this is to generate an Microsoft Excel XML file. Starting from Office 2003 this XML format is supported. This way you are able to generate a native Excel file […]
0 0 The problem I was facing was simple. You have a table with data. The data in that table should be validated. Invalid rows should be deleted. For each deleted row an entry in a logfile should be created. The validation of the rows could be performed by expensive queries. The […]
0 0 Yesterday I had a few mind boggling experiences with Oracle Lite. Together with our customer and my colleague Arjaan, I tried to install Oracle Lite. This is a very important project with 300 Oracle Lite snapshots in the future. Again I experienced what I wrote in my previous post. It’s […]
0 0 On my current assignment I am working on interfaces between Tibco and Oracle PL/SQL applications.

0 0 I recently had the need to generate XML files based on data stored in relational tables. This was done via an XML DOM implementation on the project I am currently working on. This works fine, but it’s difficult to maintain. Modifications have to be made simple because the XSD’s are […]
0 0 This post is the first one of a set that I will write about Oracle Lite. I have been working with Oracle Lite and I am impressed. Not by the level of documentation, but by the functionality of the package. Oracle Lite gives you the ability to create data snapshots […]
0 0 This post shows a simple example about how to use Oracle’s BPEL server to load and parse a datafile. The data in the file is then inserted into a database table. We use the file adapter and the database adapter to accomplish this task. The nice thing of this BPEL […]

0 0 Suppose you want to log every update on a table. You want the log records to be in the same original table. You cannot do this in a simple update trigger because this will have a the famous mutating table problem as a result. This post will describe a simple […]
0 0 Just read on news.com that the W3C consortium is considering a binary XML standard. This could really speed up a lot of transactions. The mayor drawback of course will be the fact that these messages are not human readable. I believe this could be a good thing to speed up […]
