When Erik Benner gets his hooks into new expertise, his curiosity simply will no longer let go. So tons so that when astronomy caught his fancy, he didn’t in basic terms purchase a telescope, he ended up with a well-appointed observatory. And likewise, when he started exploring what Oracle’s strongest engineered database system, Oracle Exadata, could do, he ended up with one in his basement.

Benner pushes new know-how to the limit and is unabashed about reporting lower back the good and the unhealthy. This propensity for curiosity and candor makes Benner—who owns the amorphous title of vice chairman of business transformation at tech consulting enterprise Mythics—a favored speaker at tech user community events, the place fellow facts consultants are seeking out his classes.
His newest obsession is the independent database on Oracle Cloud. purchasable considering 2018, Oracle self reliant Database deploys, manages, secures, and improvements itself without a human intervention—all projects perpetually achieved with the aid of knowledgeable database directors.
right here, after more than a yr of working with clients on a mix of self sufficient Database tasks, are four of Benner’s guidance: One to support you get all started, two that prevent money, and one gotcha to steer clear of.
how to pick Your self sufficient taste
The on-premises edition of Oracle Database 19c is a single database designed to be configured and nice-tuned on your use case by means of consultants like Benner. however Oracle self sufficient Database while using that equal Oracle Database 19c working on Exadata, has been pretuned for 2 distinctive styles of work and is managed daily through AI and desktop gaining knowledge of algorithms. these features are Oracle self sustaining statistics Warehouse for analyzing tons of information suddenly, and Oracle Oracle self sustaining Transaction Processing blended workloads.

“You’ve got to pick one up entrance,” says Benner. “in case you’re flowing lots of data into [a single place] to run evaluation, then go together with self sufficient statistics Warehouse. in case you’re now not sure [what your needs will be], go along with autonomous Transaction Processing,” Benner says. “autonomous Transaction Processing offers you a bit extra manage, and also you get a cool new feature referred to as automatic indexing,” he explains.
And although self sufficient Transaction Processing isn’t optimized for statistics warehousing like autonomous information Warehouse, “you nevertheless have the entire advantages of storage cells within the Exadata,” so you'll want to still get respectable query performance.
suitable approach self reliant Saves money: constructing a new App
“If I have been writing an app at this time, and i desired a reasonably-priced database alternative that might cloud scale, i would examine independent Database,” says Benner. “because instead of desiring three DBAs for my mission, I most effective need one.”
With autonomous Database, “I don’t need a DBA who can construct a database, I don’t want a DBA that can do all of the deploy projects, I don’t need a DBA that patches as soon as a quarter. I don’t need a DBA that knows the way to tune a posh [server cluster].”
You do nevertheless need that one skilled DBA, Benner says, it’s just that Oracle self sustaining Database frees him or her from movements initiatives with a view to do more valuable stuff. “i want a DBA who’s an software DBA; who knows how to write respectable SQL, who knows how to work with builders on their SQL, who is aware of how to structure records in a relational database,” he says. And “i would like a person who knows the way to get statistics into and out of that database. What’s the foremost formula given their funds and their wants?”
These projects give the DBA a greater visible function. You retailer income for your database mission, and the DBAs you pay “get to do stuff that’s of greater evident value to the business,” Benner says.
2nd approach self reliant Saves money: genuine scorching Scaling
while there are a few killer use situations for autonomous Database, one of Benner’s favorites is its authentic hot scaling capabilities—that means which you could scale it up or down at will. “in case you’re working a construction environment for a knowledge warehouse and handiest do one or two huge analytics workloads a month, that you can run all month on two CPUs after which in case you’re going to do your massive reviews which you could scale that thing as much as 18 CPUs, or anything you want, and take capabilities of all that parallelism, knock out your analytics, then slam it returned all the way down to 2 CPUs,” he says. “That’s big for mark downs and effectivity.”
Or “if I best need my dev and examine environment Monday through Friday between eight a.m. and 7 p.m., i will be able to simply shut the autonomous Database down and prevent paying for it during all those hours I’m now not the usage of it,” he says. “Now what have I done to my invoice?”
ultimately, a Troubleshooting Tip
One element to observe when developing an autonomous database is how resources are allotted, says Benner, because it’s distinct in Oracle autonomous Database. “I’ve had issues with self sufficient Database where a person became getting crappy efficiency, and they should still have had screaming-fast performance,” he says. After some digging, Benner realized the problem became very essential. An inexperienced administrator had given each database consumer the bottom-tier priority for access to desktop substances.
consistently, a DBA would be aware of a user’s wants and provides them the substances their work requires. “however now users can decide upon all with the aid of themselves, and that they regularly go low priced,” as a result of they pay for the cloud carrier by the CPU hour, he says. Oracle self sustaining data Warehouse has three tiers and independent Transaction Processing has five, so if a job is running slowly, “go again and examine what tier they’re related to. It can be too low for what they’re trying to do.”
As the tech world adjusts to self reliant databases, Benner should be among these main the way. At a contemporary assembly on Oracle’s leading campus, as an example, Benner, who is bestowed with the business’s excellent person title, Ace Director, brought his counsel for carrying on with to improve the self sufficient database journey and shared them with Oracle executives. They were all ears.
