Configuring RStudio Server for Oracle R Enterprise

In this blog post I will show you the configurations that are necessary for RStudio Server to work with Oracle R Enterprise on your Oracle Database server. In theory if you have just installed ORE and then RStudio Server, everything should work, but if you encounter any issues then check out the following.

Before I get started make sure to check out my previous blog posts on installing R Studio Server. The first blog post (more...)

Installing RStudio Server on an (Oracle) Linux server

In a previous blog post I showed how you can install and get started with using RStudio on a server by using RStudio Server. My previous post showed how you could do that on the Oracle BigDataLite VM. On this VM everything was nicely scripted and set up for you. But when it comes to installing it on a different server, well things can be a bit different.

The purpose of this blog post is (more...)

Installing RStudio Server on Oracle BigDataLite VM

A very popular tool for data scientists is RStudio. This tool allows you to interactively work with your R code, view the R console, the graphs and charts you create, manage the various objects and data frames you create, as well shaving easy access to the R help documentation. Basically it is a core everyday tool.

The typical approach is to have RStudio installed on your desktop or laptop. What this really means is that (more...)

Migrating application roles in OBIEE 11g

My last article talked about a maintenance and hassle free mechanism to implement security. The article moved the security architecture to roles created in EM. The next logical step is to move the roles from one environment to another because lets face it, manually creating roles is a lot of effort.


Oracle has a process to migrate the policy store from one environment to another and is described @ http://docs.oracle.com/cd/E14571_01/core.1111/e10043/addlsecfea.htm#JISEC3593

The data set that I'm using is the White Wine data set (more...)
