0 0 It is not always easy to troubleshoot ADF performance problems – it is often complicated. Many parts needs to be measured, analyzed and considered. While looking for performance problems at the usual suspects (ADF application, database, network), the real problem can also be found in the often overlooked browser load […]
0 0 If you are anything like me you will have multiple virtualboxes running on your system. Sometimes you might want to run a copy of a virtualbox for different purposes. Like running an Oracle 11 Devdays instance as test environment but also running the same vbox for customer testing. If you […]
0 0 Next the normal Google search you can use this search box for a lot more things. This search box is often the first place where you type when you want something done. Below I list 6 examples of how Google search can help you much quicker to answer a bit more complex questions. Set […]
0 0 My first article I wrote about controlling deployment sequence by artifact type extensions and modifications.That way, the deployment process itself was still completely left over to the capabilities within the distributed plug-ins. What happens if a legacy deployment process is very robust, tested out and trusted by the organization? On […]
0 0 A client of mine was busy correcting one of his development streets and therefore the NLS charactersets of about 10 11.2.0.4 EE databases had to be changed. Most of the databases were originally configured with WE8ISO8859P15, others with WE8ISO8859P1 and all of them had to get WE8MSWIN1252. Some of them […]
0 0 Sonatype Nexus provides several mechanisms to remove artifacts from the repository. You can schedule a job to keep only specified number of the latest releases (see here). You can also specifically remove a single artifact or an entire group using the API (see here). Suppose you want to make a […]
0 0 The last couple of months I have been assigned to a project dedicated to deployment automation including several levels and types of technologies: database, middleware, services and portals. The selected deployment tool is XL Deploy from XebiaLabs. One of the main challenges was to determine the proper order of the […]
0 0 Not all Oracle ADF projects are built with ADF Business Components (ADF BC). Some organizations prefer to use EJB/JPA (EclipseLink) instead of ADF BC. The EclipseLink JPA provides developers with a standards based Object-Relational persistence solution. The application still reflects the Model-View-Controller architecture. In this case the model is provided by […]
0 0 Recently we added a great new feature to the ADF Performance Monitor: network and browser load time information. Now you know exactly every end-user experience of your ADF application, in real-time. You can quickly resolve any performance bottlenecks with this end-to-end visibility. You can even drill down into an individual user to […]
0 0 – This blog post was also published on http://www.sonatype.org/ – Sonatype Nexus is an often used artifact repository. In a previous blog post I have shown an example how Maven can be used to assemble and release artifacts to Nexus. In this blog post I will describe two ways how artifacts […]
0 0 Last week I presented at the UKOUG’14 conference on creating intuitive & interactive dashboards with the ADF Data Visualization Components. Frequently end-users are overwhelmed with too much and confusing information displayed in rows and columns. It can be difficult to quickly get the relative significance. This session discussed how to create intuitive, interactive […]
0 0 One of my pet peeves is people using GUI tools like Toad or SQL Developer while running release scripts on test, acceptation or production systems. Actually, pet peeves is putting it too mildly. Ive had to troubleshoot enough incidents because of this to hold a serious grudge against that careless […]
0 0 When using Oracle Unified Directory (OUD) as an identity store, it is in some occasions needed to add OUD users to OUD groups by hand. When you have to grant privileges to one user, this is easily done through the Oracle Directory Services Manager (ODSM) interface. However doing so for […]
0 0 An important part of a release process is storing artifacts in an artifact repository. Many customers use custom implementations of artifact repositories (such as file shares in combination with custom scripts) but there are also products which offer many functions of such a repository (and probably many more) out of […]
0 0 Doing a FTP-job with PL/SQL is not difficult. A basic implementation of RFC 959 can be written in a few hundred lines. See for instance ORACLE-BASE, How to FTP with Oracle PL/SQL or Oracle FAQ’s But what if you want to secure your FTP transmission. Google doesn’t find any pure […]

0 0 Like other web applications, Oracle ADF applications potentially use a lot of JVM memory. Many times, the root cause of a high memory usage is that application data retrieved from the database into memory is not properly limited; hundreds or thousands of rows (with too many attributes) are fetched and […]
0 0 The convergence project between Oracle’s JVMs JRockit and Hotspot is making significant progress. Included in the latest Java 7 JDK update (‘7u40’) is a new powerful monitor tool: Java Mission Control (JMC). JMC is a production time tool that has its roots in the JRockit JVM tooling. It is located in the […]
