IOUG Collaborate 2017 Sessions

IOUG Collaborate 2017 will be held from April 2 - 6 2017 in Las Vegas Nevada. This will be my fifth year speaking at Collaborate, and I will have two separate sessions about data virtualization. One will be a pre-conference Hands-On lab with Kellyn Pot'Vin-Gorman, and the other will be talking about Cloud migration.  I will also be doing booth duty for Delphix. If you are around please stop by and say hello. See session details below.

April 2, 2017 9:00 AM – 1:00 PM – South Seas C Data Virtualization Hands-On Lab (pre-registration required) Presenters: Kellyn Pot’Vin-Gorman and Leighton Nelson
April 3, 2017 8:30 AM – 9:30 AM – Palm A Migration Enterprise Applications to the Cloud Presenter: Leighton Nelson

Databases and Storage - The New Frontier

Databases Storage – The New Frontier
As database and storage administrators and engineers, it is important to understand the effect that storage has on database performance.

It is important to understand that databases are an extension of your storage and requires a holistic view when designing and managing solutions that use the database.

This article gives an overview of the Oracle database storage landscape – past, present and future. It’s not meant as an in-depth technical treatment of the topic but opens the door for more discussion and engagement about database storage.
Evolution Both storage and databases continue to evolve (albeit at different paces). About a decade ago the enterprise storage of choice was the Storage Area Network or SAN array. At about the same time the current release of Oracle was 10gR1, which introduced Automatic Storage Management (ASM), which provided mirroring and striping capabilities for data files. Database sizes were typically in the hundreds of gi…

Oracle Home Cloning: Tools and Techniques

One of the many necessary and frequent tasks that a database administrator performs before creating a database is installing the Oracle database binaries. These binaries form what is known as an Oracle Home (referenced by the ORACLE_HOME environment variable on Linux and UNIX environments). Unfortunately, this is also one of the most mundane and uninteresting tasks a DBA can perform. So like all good DBAs know, the best way to deal with such repetitive task is to automate it. Automating installations of Oracle database binaries enables us to reliably repeat the process to enable faster installation as well as provide identical copies of the software in multiple environments.

Fortunately, Oracle allows us to clone the Oracle database binaries from one environment to another. Cloning your Oracle binaries from a source copy with all the necessary patches applied enables us to have gold images which can then be deployed to multiple environments.

The procedure for cloning an Oracle home in…
