In this blog I will show you how easy it is to build a process with Oracle Workflow. This demo consist of an automatic step (plsql function) and a FYI notification. The process will be deployed in the workflow environment described in my previous blog (Part 1). Workflow […]
Maybe the following question will arise after reading the title: Oracle Workflow isnâ€™t that obsolete technology? The answer can be very short: Yes it is. (Read the SOD on http://www.oracle.com/technology/products/ias/workflow/workflow_sod.html)But itâ€™s still interesting enough to dive into it. Oracle Workflow is heavy used in the E-Business Suite and also used […]

With all those fancy plug-ins for Microsoft tools release 2 of Oracle Grid Control 10g seems to be a must-have. However, according to many postings on the internet, installation on SuSE Linux is quite a job and release 2 is not (yet?) available for Windows. So, there’s a challenge that […]
Some time ago a customer of AMIS asked me to setup the automatic deployment of the software for their application. Till then this was done manually, took an awful lot of time and was rather error-sensitive. The application itself is a multi-tier application with an Oracle database, a Micro Focus […]
Great article about ASM on the website of Howard Rogers: http://www.dizwell.com/oracle/articles/desktop_asm.html For both Linux and Windows.
After the announcement of Oracle XE I got really curious about the possibilities of a free Oracle10g database. OK, it is limited to 4GB and it doesn’t allow things like partitioning but still… very usefull for smaller companies and web applications. So, I downloaded the Win32 version from OTN to my laptop […]
Oracle announces release 6 of their In Memory database, more details here. Faster, bigger, better and easier… well, let’s try it first.
We all know partitioning for performance issues or for storing historical data. But partitioning can also be used for functional purposes such as creating a savepoint in batchrun. Such a savepoint can be used to undo a specific part of a batch without the use of home made software. Lets […]
In my last two posts (Hibernate + Middlegen Roundtrip Development applied and Hibernate: dealing with lazy loading inevitable), I explained how to construct a J2EE application bottom-up using Hibernate and Middlegen. It turns out that you can and actually should optimize the generated .hbm and .java files by Middlegen. I […]
Some Maven multiproject experiences will be described in this post. Special attention is paid to the dashboard plug-in.
For one of our projects, we wanted to copy the contents of our production database to the test database. Both databases are accessible via JDBC. After an investigation of available tools, I had to revert to my own solution.
There seems to be a problem in the PHP code of the Wp-Dstats2 statistics plug-in for WordPress. The problem occurs when your number of unique visitors (unique IPs) grows large, typically somewhat less that 30.000.
In the whitepaper titled Modeling Stateful Resources with Web Services by Ian Foster et. al. the latest developments with respect the modeling of state with web services are very clearly introduced and discussed.

In Struts, JAAS, Tomcat: getting acquainted (part 1) it was discussed how to employ JAAS authentication for custom and/or legacy realms under Tomcat. As authorization was left unaddressed, we herewith fullfil our promise to treat it later.
In Hibernate + Middlegen Roundtrip Development applied it was shown how to generate Hibernate POJOs + mapping files from a legacy (SQL server) database. As soon as business objects start using these POJOs, you almost immediately need to deal with the problem that one query may cause the whole database […]
The Java Authentication + Authorization Service (JAAS) provides a standard API for making non-standard (i.e. custom) realms available to your application server, see e.g. this article on JavaWorld. To reiterate, a realm is a “database” of usernames, passwords and roles that identify valid users of a (web) application, where multiple […]
