The Business Intelligence, Warehousing and Analytics SIG is a part of IOUG and this year also hosts the 11th Annual Oracle Spatial Summit, giving us three days of database-centric content touching most areas of the (more...)

Rittman Mead’s Development Cluster, EM12c and the Blue Mendora VMware EM Plugin

For development and testing purposes, Rittman Mead run a VMWare VSphere cluster made up of a number of bare-metal servers hosting Linux, Windows and other VMs. Our setup has grown over the years from a bunch of VMs running on Mac Mini servers to where we are now, and was added-to considerably over the past twelve months as we started Hadoop development – a typical Cloudera CDH deployment we work with requires six or more (more...)

Using Oracle Big Data SQL to Add Dimensions and Attributes to Hadoop Reporting

In a previous post I looked at using Oracle’s new Big Data SQL product with ODI12c, where I used Big Data SQL to expose two Hive tables as Oracle external tables, and then join them using the BETWEEN operator, something that’s not possible with regular HiveQL. In this post I’m going to look at using Oracle Big Data SQL with OBIEE11g, to enable reporting against Hive tables without the need to use Hive ODBC (more...)

Connecting OBIEE11g on Windows to a Kerberos-Secured CDH5 Hadoop Cluster using Cloudera HiveServer2 ODBC Drivers

In a few previous posts and magazine articles I’ve covered connecting OBIEE11g to a Hadoop cluster, using OBIEE 11.1.1.7 and Cloudera CDH4 and CDH5 as the examples. Things get a bit complicated in that the DataDirect Apache Hive ODBC drivers that Oracle ship are only for HiveServer1 and not the HiveServer2 version that CDH4 and CDH5 use, and the Linux version of OBIEE 11.1.1.7 won’t work with the (more...)
