I travel and a seriously good amount. I will present at about 35-40 events, attend company functions/meetings and this year with a considerable amount of those outside of the Denver area, this means I’ll be on a plane around 5-6 trips per month. Women commonly pack more, but I receive a few comments per my average three day trip on how I’m able to travel with a 16 inch carry-on. I’m picking up new tricks every day, but the one thing I’ve come to learn, once you find a great travel trick, you have a tendency to look no further…

So we’ve covered a few basics of a Linux host in Part I– The File System Users, groups Basic Commands with basic arguments And file and directory permissions Hopefully, what I share next will build on the first post and enhance your knowledge as you move forward with Linux. Reading the contents of a directory, gathering information on files and locating files are some of the most common tasks a DBA will perform as they work on a server. Many of the following commands require you to “pipe” a second command onto the first. This is done by joining the…

For the Oracle DBA, Linux is life. When I was at Oracle, Linux projects were the easy part of my job, unlike the ones on Windows, AIX, HP-UX and at times, even Solaris. You knew the Linux ones received the most love from development, had the most time towards patching and received attention if there was a bug. History Linux was introduced in 1991, thanks to Linus Tovalds and has been in active development, with introduction of different “flavors” of the OS over the years. As many folks know, Linux was carved out of the GNU open license project, which…

As I continue to dig into the legacy we’re impacted by in technology, I had the opportunity to read Disrupt or Die, the new book from Delphix and Avamar founder, Jedidiah Yueh. I was first concerned that the content wouldn’t be that interesting to someone from the deep technical like myself… To be honest, I ended up quite captivated by the history lessons surrounding some of our most successful technology companies, like Facebook, Google, Salesforce and others. The book discusses, in Jed’s own words, something that I’ve always referred to as “the power in the simple act of doing” and…

Just in case you wondered, if you do a search for #ThanksODC and leave the “C” off, you get a lot of stuff on the boy band, One Direction…. You can thank me later for that warning…. The sheer amount of thank you posts for Oracle Development Community Appreciation Day, (#ThanksODC) and the historical hashtag for reference, #ThanksOTN are impressive, but I waited a day on mine so I could continue the support for the Oracle Women in Technology, (and @ORAWit). Here are the ThankODC blog posts from the great women of the Oracle Community! I’m going to start with…

The first edition of the free eBook is available for download at Delphix! It took us a bit to get the final updates to the eBook version completed and I want to thank everyone at Delphix who helped get the content updated with the latest additions, including the bossman, Eric Schrock and for helping me keep it all organized and finalized, shoutouts to Rita Rosenberg. If you’re interested in downloading a PDF copy, simply go to this link and get a version for yourself and find out what you need to know as a DBA about where we fit into…

So now that I’m finished just taking it easy, playing hooky from Oracle Open World and Oak Table World…uh, yeah…. I get to recover from emergency surgery for another week and while I’ve been busy writing slide content, building out new abstracts for the new year, along with content for a couple books, I’m finishing chapters on. My ebook is about to come out for DevOps for the DBA: The Next Frontier, (I’ll be giving a few hard copies away at events in the next couple of months, but you can get a free copy at Delphix.com soon!) This is…

Somehow I’ve made it a pastime of pointing out how many times women are passed up for recognition while men are promoted around them. Its not that the men were identified as better or worse than women, but just about how heavily we scrutinize and limit women while everyone else passes them by. Now I’m going to ask the Oracle folks to not take this personally, but hopefully take it as a call to arms, but I know how we love to shoot the messenger. Hopefully you already know that I will have no qualms about deleting abusive or threatening…

The network has often been viewed as “no man’s land” for the DBA- Our tools may identify network latency, but rarely does it go into any details, designating the network outside our jurisdiction. As we work through data gravity, i.e. the weight of data, the pull of applications, services, etc. to data sources, we have to inspect what connects it to the data and slows it down. Yes, the network. We can’t begin to investigate the network without spending some time on Shannon’s law, also known as Shannon-Hartley Theorem. The equation relates to the maximum capacity (transmission bit rate) that…

As we come upon Oracle Open World at the end of the month, I’m busy with a number of events and tasks. I spoke at the Microservices, Containers and DevOps Summit in Denver yesterday and will be traveling to San Diego, California to speak at SQL Saturday #661 this weekend. I love the Microsoft events, but not sure my family loves the loss of my weekend time with them half as much. At the end of the month, Delphix will be publishing my DevOps book based off my series of blog posts and webinars on DevOps and the DBA. It…

I planned on finishing up and publishing a different post today, but after a number of conversations with DBAs in the community, this topic took precedence. Yesterday the above announcement came out with the Oracle earnings call, along with the following: “In a couple of weeks, we will announce the world’s first fully autonomous database cloud service,” said Oracle Chairman and CTO, Larry Ellison. “Based on machine learning, the latest version of Oracle is a totally automated “self-driving” system that does not require human beings to manage or tune the database. Using AI to eliminate most sources of human error…

It was a really busy summer and ended with me returning after a week of vacation in Singapore. What should I do after a 17hr flight and jet lag? Two webinars and a SQL Saturday event! What better way to get over jet lag and get my game back on and just jump back in! I started out by having a webinar this morning on “DBA to DevOps to DataOps- the Revolution.” I had a feeling with the jet lag, I’d be done faster than I’d hoped, but with the amount of questions from the over 400 attendees, it was…

Data gravity and the friction it causes within the development cycle is an incredibly obvious problem in my eyes. Data gravity suffers from the Von Newmann Bottleneck. It’s a basic limitation on how fast computers can be. Pretty simple, but states that the speed of where data resides and where it’s processed is the limiting factor in computing speed. OLAP, DSS and VLDB DBAs are constantly in battle with this challenge. How much data is being consumed in a process, how much must be brought from disk and will the processing required to create the results end up “spilling” to…

Delphix Engineering and Support are pretty amazing folks. They continue to pursue for solutions, no matter how much time it takes and the complex challenges they’re faced with supporting heterogenous environments, hardware configurations and customer needs. This post is in support of the effort from our team that resulted in stability to a previously impacted Solaris 11.2 cluster configuration. The research, patching, testing and then resulting certification from Oracle was a massive undertaking from our team and I hope this information serves the community, but in no way is recommended by Delphix. It’s just what was done to resolve the…

There was a great post by Noel Yuhanna on how he deems the number of DBAs required in a database environment by size and number of databases. This challenge has created a situation where data platforms are searching for ways to remove this roadblock and eliminate the skills needed to manage the database tier. I’ve been a DBA for almost 2 decades now, (“officially” as my beginning date with an official title and my years experience differ by a couple years…) When I started, we commonly used import and export features to move data from one data source to another.…

Even though my social media profile is pretty available for Twitter and Linked in, I’m significantly conservative with other personal and financial data online. The reversal of the Internet Privacy Rule, (I’ve linked to a Fox news link, as there was so much negative news on this one…) had everyone pretty frustrated, but then we need to look at security of personal information, especially financial data and as we can see by security breaches so far in 2017, we all have reason to be concerned. The EU has taken the opposite approach with the right to be forgotten, along with…

I’m off to Columbus, Ohio tomorrow for a full day of sessions on Friday for the Ohio Oracle User Group. The wonderful Mary E. Brown and her group has set up a great venue and a fantastic schedule. Next week, I’m off to SQL Saturday Vancouver to present on DevOps for the DBA to a lovely group of SQL Server attendees. It’s my first time to Vancouver, British Columbia and as it’s one of the cities on our list of potential future locations to live, I’m very excited to visit. Speaking of SQL Server- Delphix‘s own SQL Server COE, (Center…

In my latest blog post on the Delphix site, I continue my conversation with why DevOps is the next step for DBAs and how DBAs can embrace this next step in their evolution. This is an extensive series of blog posts, (four so far) to be followed by an ebook, a podcast and two webinars. One is to be announced soon from Oracle called, “The DBA Diaries” and the other will be a from Delphix, titled, “The Revolution: From Databases and DevOps to DataOps“. The goal for all of this is to ease transition for the Database community as the…
