Using HAWQ with PHD service in PCF 1.2

The following demo shows how to use the PCF 1.2 PHD service with HAWQ by loading data into the PCF PaaS platform.

1. First lets setup our ENV to use the correct version of HADOOP on our local laptop.

export HADOOP_INSTALL=/Users/papicella/vmware/software/hadoop/hadoop-2.0.5-alpha
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home

Silence

Silence. Sometimes sought after, but in reality almost certainly feared - the absence of not just sound but voice. Silence is often associated with divine encounter - the neptic tradition of the Philokalia comes to mind - but also and perhaps more accurately with abandonment, divine or otherwise.

Why Oracle Big Data SQL Potentially Solves a Big Issue with Hadoop Security

Oracle announced their Big Data SQL product a couple of weeks ago, which effectively extends Exadata’s query-offloading to Hadoop data sources.

Right click on the integratedWebLogicServer in Application Window and select properties->Launch Settings
 

Introduction to FMW 12C REST adapter

In this entry, I will present the usage of the new REST adapter using OSB 12C.  This adapter is a new feature providing support for RESTful web services; it also supports JSON request and response.   One important thing to keep in mind is the internal implementation of the message within OSB is SOAP/XML, there are transformations between JSON and XML during the message processing.
 
Use Case
 
I have deployed a JAX-RS service on the server with the following interfaces and we are going to expose this on OSB.
