I blogged about Dynamic Resource Mastering (DRM) in RAC here . DRM freezes the global resources during the reconfiguration event and no new resources can be allocated during the reconfiguration. This freeze has a dramatic effect of inducing huge amount of waits for gc buffer busy [acquire|release] events and other gcs drm freeze release, gcs […]
A little while ago I highlighted a special case with the MINUS operator (that one of the commentators extended to include the INTERSECT operator) relating to the way the second subquery would take place even if the first subquery produced no rows. I’ve since had an email from an Oracle employee letting me know that […]

Do you fear migration downtime for your always-on applications and
increase in already long IT projects backlog? Overdue for an upgrade on
your AIX/Power systems running Oracle technology and/or Oracle
Simplify the Migration of Oracle Database and Oracle Applications from AIX to Oracle Solaris
is a new white paper that explains in detail how to move from AIX to Oracle Solaris. It also has published results of Oracle Database migrations from AIX to Solaris, including the
effort, duration, and benefits from actual systems migrations. Hear
first-hand from customers who have simplified operations and benefited
from UNIX advantages, by moving off IBM AIX systems onto Oracle’s
cutting edge Oracle Solaris-powered platforms.
In four simple
steps, you can migrate from AIX to Oracle Solaris and take advantage of
Oracle’s “Hardware and Software Engineered to Work Together” to reduce
cost, risk and improve the productivity of your application and business

Yesterday’s flight to Bangalore was pretty quick, about 80 minutes if I remember correctly. We landed and were picked up by a car from the hotel. We were told the traffic would be terrible in Bangalore, but it wasn’t too bad. Debra managed to keep her eyes open for much of the journey. There were […]

The transformation to an all-digital workflow, from content creation,
Shooting with HD and newer UltraHD
- Some of the latest HD cameras produce up to 85TB of data throughout a
24 hour shoot; and these “dailies” need to be backed up, essentially
doubling the amount of storage
- The 3D movie Avatar
used over one Petabyte of storage; industry experts predict that future
feature-length digital motion pictures will consume an Exabyte of
storage from initial capture to final cut
So, where will all this data be stored? On efficient and economic digital tape, of course. At Oracle, we recently announced two new storage technologies—the StorageTek T10000D tape drive and Linear Tape File System–that are being embraced by the Media & Entertainment industry. Our StorageTek T10000D tape technology is the highest capacity storage technology available today. At 8.5TB per cartridge, it is more than 2x the capacity of today’s 4TB disk drives. And due to its unique scalability, discrete cost and power/cooling advantages, tape storage (at scale, re: petabyte[s]), carries a total cost of ownership (TCO) that is 26x lower than conventional disk storage.
In addition, the T10000D supports the Linear Tape File System (LTFS) format, which enables users to easily access files on tape just like a thumb drive or a NAS device. LTFS is popular across the film, video and broadcasting segments. In fact, the StorageTek T10000D with LTFS recently won Best Professional Media and Entertainment Class Archive Storage at the 2014 Storage Visions Conference. I know it’s a mouthful, but there you have it!
While you may be surprised that tape is in high demand in the Media & Entertainment industry, this is not an isolated case. Indeed, industry influencers and the media have pronounced a resurgence of tape (follow the links below):

- Rise of the Machines: The Rebirth of Tape – Wikibon
- Disk-pushers, Get Reel: Even GOOGLE Relies on Tape – The Register
- Magnetic Tape to the Rescue – The Economist
- Meeting Exa-Scale Archive Requirements in the Digital Age of Media and Entertainment – Coughlin Associates
So, when you watch the Oscars, think of the many Petabytes of digital content to be archived and preserved for posterity—and how Oracle StorageTek tape solutions are addressing the Media & Entertainment industry’s storage challenges.
To learn more about how digital tape storage is helping the Media & Entertainment industry to overcome challenges arising from the transition to an all digital business visit the Oracle booth (SL 13909) at NAB in Las Vegas, April 7-10.
