Using the JAX-RS 2.0 Client API with WebLogic Server 12.1.3

As part of the JAX-RS 2.0 support we are providing with WebLogic Server 12.1.3, one really useful new feature is the new Client API it provides, enabling applications to easily interact with REST services to consume and publish information.

By way of a simple example, I'll build out an application that uses the REST service to lookup the physical location of a specified IP address or domain name and deploy it to WebLogic Server 12.1.3.

Using Oracle R Enterprise to Analyze Large In-Database Datasets

The other week I posted an article on the blog about Oracle R Advanced Analytics for Hadoop, part of Oracle’s Big Data Connectors and used for running certain types of R analysis over a Hadoop cluster.

Using Sqoop for Loading Oracle Data into Hadoop on the BigDataLite VM

This is old-hat for most Hadoop veterans, but I’ve been meaning to note it on the blog for a while, for anyone who’s first encounter with Hadoop is Oracle’s BigDataLite VM.

Using JAX-RS 2.0 in WebLogic Server 12.1.3

We've been working on adding some Java API updates to the coming WebLogic Server 12.1.3 release.

One that I think is going to be very popular is JAX-RS 2.0, which includes some useful new capabilities around filtering, interception and a really useful new client API.

Purging corrupted OBIEE web catalog users

Sometimes it can happen that user profiles within a web catalog become corrupted for any number of reasons. In order for these user profiles to be correctly re-initialized, there's more to be done than just drop /users/JohnDoe from the web catalog.

All in all there are three distinct places which need to be cleaned:

WebLogic 12.1.2 Per Domain Nodemanger Command Line Arguments

Stepping out of any WebLogic admin training you will know that before WebLogic 12.1.2 we could start the node manager (NM) using its listen address and its port number as command-line arguments overwriting the settings in the file. This is still possible, but doesn’t work OOTB for the per domain NM which was introduced in […]

Don't use INC and DEC in PL/SQL Libraries

In my oldest PL/SQL-Library in Forms 4 my first procedures were:

P_Number := P_Number + 1;

P_Number := P_Number - 1;

In some variations with one or two parameters I used this Increment and Decrement since 20 years! Without having trouble in all the days.

Now I found out, that DEC isn't working in newer Oracle Forms versions...

Part 2: Advanced Apache JMeter Stress Testing OAM and LDAP

In “Part 1: How To Load Test OAM11g using Apache JMeter” I talked about an example plan that could be used to load test OAM11g, which included some common configuration elements, some samplers for login, authorization, logout, and some listeners that provided result analysis.   In Part 2, I wanted to expand on an option to make JMeter send random logins and I will explain why, and then cover how to leverage JMeter to load test an LDAP server like OUD, OID, ODSE, or OVD.

Using the Maven Release plugin with Mercurial SCM

The Maven Release plugin can be used to release a project using Maven. Normally, a release can be made in two simple steps: prepare en perform. When the Mercurial SCM (Source Code Management) is used, this process requires a little more configuration. I performed the described steps using Hg (Mercurial) version 2.0.2 and maven-release-plugin version 2.4.2 on a Ubuntu 12.04 VM. The used distribution servers are Nexus 2.2-01 instances.
