How Oracle’s Embrace Of OpenStack Will Help Customers Adopt The Cloud

Oracle ORCL -0.27 % is now one of the sponsors of the OpenStack Foundation, a show of support that has been welcomed by many across the technology sector. But also a technical challenge many CIO – – Oracle to support the development of interoperable hybrid clouds , which are an opportunity for growth will accelerate.

Oracle said it was moving in this direction, in September 2013 , when a roadmap for software recently acquired by Oracle Nimbula Director delivering infrastructure as a service (IaaS ), which includes the integration of OpenStack API is provided Oracle Exalogic elastic cloud , a cloud high performance device . See the formal announcement for details on this important new development.

With that as a first step , Oracle simulation has made a further commitment to OpenStack in December 2013 with the announcement of two parts. First, Oracle has become a sponsor of the OpenStack Foundation, a community dedicated to the promotion of OpenStack .
Secondly , Oracle has announced plans to provide functionality for OpenStack in a wide range of Oracle Study Guides products, including Oracle Solaris , Oracle Linux , Oracle VM , Oracle Virtual Compute Appliance , Oracle ZS3 series and Pillar Axiom Storage Systems and StorageTek tape systems , and to achieve compatibility OpenStack Cloud Compute and Cloud Storage Oracle .

OpenStack is a collection of software components that together make open source operating systems in the cloud. The project was launched in 2010 and formed the OpenStack Foundation in 2012. As a technical journalist , I covered the beginnings of the nascent operating system formerly known NASA OpenStack clouds .

Oracle ‘s participation is important because it is one of the few technology companies that provide complete solutions in hardware and software for creating private clouds , as well as a full range of public cloud services .

Welcoming the fold of Oracle , Mark Collier , Director of Operations of the OpenStack Foundation, said : “We hope the innovative contributions of many experts in the [ Oracle ] field , while we continue to pursue the vision of a common management platform the cloud. ”
So if it is a big problem that Oracle has thrown its weight behind OpenStack , the real turning point for customers is that OpenStack is woven into the popular systems of Oracle software company and services to the public cloud .

“The integration of OpenStack will give customers greater flexibility and ease of use for managing OpenStack clouds based on Oracle technology, taking advantage of the stability , efficiency , performance , scalability and security products Oracle , “said Rex Wang , VP of Product marketing at Oracle.

Here are some of the ways Oracle’s commitment to OpenStack will come to fruition:

• The integration of Oracle Solaris, the major version of the UNIX operating system OpenStack means that customers can use Oracle Solaris for a wider range of the deployments in the cloud and in combination with other compatible OpenStack clouds. Similarly, the IT team will be able to integrate Oracle Solaris Zones and Oracle VM environments with other platforms OpenStack.
• Compatibility between Oracle and OpenStack Nova Compute Cloud should allow a simpler virtualized computing services via cloud management. Oracle Cloud Compute currently in preview mode, allows users to launch VM instances in demand that are configured to your needs.
• Oracle plans to establish compatibility between Oracle  test questions and OpenStack Swift Cloud Storage for object storage services in the cloud. Oracle also integrate OpenStack in their line of storage products, so that customers can access Oracle ZFS Storage Appliance, Pillar Axiom systems and StorageTek tape solutions using the OpenStack API.

Enterprise Scale

These events are of vital importance as companies shift the curve of adoption of cloud use some of the cloud services for many. In the process , they begin to recognize the need for enterprise cloud solutions are built with the integration of class and interoperability in mind.

“We understand that our customers need to have common management interfaces , rather than being stuck in private ,” said Markus Flierl , VP of Oracle Solaris software development . ” OpenStack allows them to do so , both for the utility more traditional IaaS environments and our Oracle systems designed. ”

Through all of this support and integration APIs,Oracle brings enterprise level and the strength of the OpenStack environments.Organizations can run business applications OpenStack clouds, and you will be able to choose from a wider range of hardware for OpenStack clouds , including Oracle SPARC and buildings systems.In summary,support OpenStack Oracle training course offers a greater capacity for choice , flexibility, interoperability and the company has provided to public and private clouds.

Oracle SQL Developer and Database Auditing

Did you know Oracle actual test SQL Developer allows you to configure Database Auditing and view your audit trails? Well, now you do!

This is not new for version 4.0, but the screenshots in this post are from version 4.0. This feature is available under the DBA panel, which can be found on the View menu.

Control what’s logged and browse the logs all in one place.

I won’t say whether Database Auditing is the right solution for you – I don’t know your requirements, but I WILL say this: I’m always surprised when folks build their own auditing system. I would advise you try what we’ve built for you first.

Anyways, if you want to see what’s going on in your database, open the Audit Settings node under the Security piece in the DBA tree.

It’s MORE than just the settings though, it’s all the trails.

The Failed Logins and Objects Audit Trails

Ok, so this feature is in v3.2, but what I’m showing above is a SQL Developer v4 feature – the cloned editor. This allows me to open the Audit Settings Document TWICE. After I clone it, I create a new document tab group so I can see both at the same time. Be sure to master the clone/tab group trick for maximum SQLDev experience points

Changing the Audit Settings

Maybe you want to add something to be tracked. Just right-click on the Audit Settings node and choose what you want.

Change what’s being recorded.

I want to record anytime the HR user issues a GRANT on a table…

Switch to the SQL panel is you want to see the command to be issued…

Remember, nothing’s free.

I know that sounds weird, especially since we’re (SQL DEVELOPER) essentially a free product. But if you ask the database to log addditional information, that has a cost – I/O, CPU, whatever. Be sure to only ask for what you need. And read the advice on the auditing link I shared in the first paragraph of this post – it will help you minimize overhead on your systems.
