Different combination in the game of tech create a winning roll of the dice and other times create a loss. Better communication between teams can offer a better opportunity to deter from holes in development cycle tools, especially when DevOps is the solution you’re striving for. It doesn’t hurt to have a map to help guide you. This interactive map from XebiaLabs can help offer a little clarity to the solutions, but there’s definitely some holes in multiple places that could be clarified a bit more. The power of this periodic table of DevOps tools, isn’t just that they are broken…

I had the opportunity to attend Delphix‘s Company Kick Off last week in San Francisco. This was my first time at an event of this nature and it was incredibly successful. As Delphix had just promoted Adam Bowen and me to the Office of CTO, along with promoting Eric Schrock to the CTO position, I was in an enviable position, but not just because of the role change. For some reason, my badge stated I was in Product Management, (I wasn’t) and as I was transitioning from my previous role in Technical Product Marketing, (I was the full-on techie on the team.)…

This was received by one of our Delphix AWS Trial customers and he wasn’t sure how to address it. If any others experience it, this is the why it occurs and how you can correct it. You’re logged into your Delphix Administration Console and you note there is a fault displayed in the upper right hand console. Upon expanding, you see the following warning for the databases from the Linux Target to the Sources they pull updates from: Its only a warning and the reason it’s only a warning is that it doesn’t stop the user from performing a…

When tearing down an AWS Delphix Trial, we run the following command with Terraform: >terraform destroy I’ve mentioned before that every time I execute this command, I suddenly feel like I’m in control of the Death Star in Star Wars: As this runs outside of the AWS EC2 web interface, you may see some odd information in your dashboard. In our example, we’ve run “terraform destroy” and the tear down was successful: So you may go to your volumes and after verifying that yes, no volumes exist: The instances may still show the three instances that were created as part of the trial, (delphix…

Now, for most of us, we’re living in a mobile world, which means as our laptop travels, our office moves and our IP address changes. This can be a bit troubling for those that are working in the cloud and our configuration to our cloud relies on locating us via our IP Address being the same as it was in our previous location. What happens if you’re IP Address changes from what you have in your configuration file, (in Terraform’s case, your terraform.tfvars file) for the Delphix AWS Trial? I set my IP Address purposefully incorrect in the file to demonstrate what…

I ran across an article from 2013 from Straight Talk on Agile Development by Alex Kuznetsov and it reminded me how long we’ve been battling for easier ways of doing agile in a RDBMS environments. Getting comfortable with a virtualized environment can be an odd experience for most DBAs, but as soon as you recognize how similar it is to a standard environment, we stop over-thinking it and it makes it quite simple to then implement agile with even petabytes of data in an relational environment without using slow and archaic processes. The second effect of this is to realize that we…

So you thought you were finished configuring your AWS target, eh? I already posted a previous time on how to address a fault with the RMEM, but now we’re onto the WMEM. Wait, WM-what? No, I fear a DBAs work is never over and when it comes to the cloud, our skill set has just expanded from what it was when we worked on-premise! Our trusty Delphix Admin Console keeps track of settings on all our sources and targets, informing us when the settings aren’t set to what is recommended, so that we’ll be aware of any less than optimal…

There are more configurations for AWS than there are fish in the sea, but as the rush of folks arrive to test out the incredibly cool AWS Trial for Delphix, I’ll add my rendition of what to look for to know you’re AWS setup is prepped to successfully deploy. The EC2 Dashboard View After you’ve selected your location, set up your security user/group and key pairs, there’s a quick way to see, (at least high level) if you’re ready to deploy the AWS Trial to the zone in question. Go to your EC2 Dashboard and to the location, (Zone) that…

Delphix focuses on virtualizing non-production environments, easing the pressure on DBAs, resources and budget, but there is a second use case for product that we don’t discuss nearly enough. Protection from data loss. Jamie Pope, one of the great guys that works in our pre-sales engineering group, sent Adam and I an article on one of those situations that makes any DBA, (or an entire business, for that matters) cringe. GitLab.com was performing some simple maintenance and someone deleted the wrong directory, removing over 300G of production data from their system. It appears they were first going to use PostgreSQL…

I’ve been at Delphix for just over six months now. In that time, I was working with a number of great people on a number of initiatives surrounding competitive, the company roadmap and some new initiatives. With the introduction of our CEO, Chris Cook, new CMO, Michelle Kerr and other pivotal positions within this growing company, it became apparent that we’d be redirecting our focus on Delphix’s message and connections within the community. I was still quite involved in the community, even though my speaking had been trimmed down considerably with the other demands at Delphix. Even though I wasn’t submitting abstracts to…

I don’t want to alarm you, but there’s a new Delphix trial on AWS! It uses your own AWS account and with a simple set up, allows you to deploy a trial Delphix environment. Yes, you hear me right- just with a couple steps, you could have your own setup to work with Delphix! There’s documentation to make it simple to deploy, simple to understand and then use cases for individuals determined by their focus, (IT Architect, Developer, Database Administrator, etc.) This was a huge undertaking and I’m incredibly proud of Delphix to be offering this to the community! So…

So you’ve deployed targets with Delphix on AWS and you receive the following error: It’s only a warning, but it states that you’re default of 87380 is below the recommended second value for the ipv4.tcp.rmem property. Is this really an issue and do you need to resolve it? As usual, the answer is “it depends” and its all about on how important performance is to you. What is net.ipv4.tcp.rmem? To answer this question, we need to understand network performance. I’m no network admin, so I am far from an expert on this topic, but as I’ve worked more often in…

We, DBAs, have a tendency to over think everything. I don’t know if the trait to over think is just found in DBAs or if we see it in other technical positions, too. I believe it corresponds to some of why we become loyal to one technology or platform. We become accustomed to how something works and it’s difficult for us to let go of that knowledge and branch out into something new. We also hate asking questions- we should just be able to figure it out, which is why we love blog posts and simple documentation. Just give us the…

On the first day with Delphix, I provisioned with glee, an IT Manager Happy. On the second day with Delphix, I provisioned with glee, two SAP ASE and an IT Manager Happy. On the third day with Delphix, I provisioned with glee, three Oracle Databases, two SAP ASE and an IT Manager Happy. On the fourth day with Delphix, I provisioned with glee, four EBS Clones, three Oracle Databases, two SAP ASE and an IT Manager Happy. On the fifth day with Delphix, I provisioned with glee… Five Cloud Migrations! Four EBS Clones, three Oracle Databases, two SAP ASE and…

I thought I’d do something on Oracle this week, but then Microsoft made an announcement that was like an early Christmas present- SQL Server release for Linux. I work for a company that supports Oracle and SQL Server, so I wanted to know how *real* this release was. I first wanted to test it out on a new build and as they recommend, along as link to an Ubuntu install, I created a new VM and started from there- Ubuntu Repository Challenge There were a couple packages that were missing until the repository is updated to pull universe by adding…

I’ll be attending my very first Pass Summit next week and I’m really psyched! Delphix is a major sponsor at the event, so I’ll get to be at the booth and will be rocking some amazing new Delphix attire, (thank you to my boss for understanding that a goth girl has to keep up appearances and letting me order my own Delphix ware.) Its an amazing event and for those of you who are my Oracle peeps, wondering what Summit is, think Oracle Open World for the Microsoft SQL Server expert folks. I was a strong proponent of immersing in…

My sabbatical from speaking is about to end in another week and it will return with quite the big bang. Oct. 14th First up is Upper NY Oracle User Group, (UNYOUG) for a day of sessions in Buffalo, NY. I’ll be doing three talks: Virtualization 101 The Limitless DBA AWR and ASH with Database 12c Oct 25th-28th I’ll be at Pass Summit! I’ve been wanting to attend this conference since I was managing MSSQL 7 databases! I finally get to go, but as I’m newly back in the MSSQL saddle, no speaking sessions for me. I do have a number…

The topic of DevOps and and Agile are everywhere, but how often do you hear Source Control thrown into the mix? Not so much in public, but behind the closed doors of technical and development meetings when Agile is in place, it’s a common theme. When source control isn’t part of the combination, havoc ensues and a lot of DBAs working nights on production with broken hearts. Control Freaks So what is source control and why is it such an important part of DevOps? The official definition of source control is: A component of software configuration management, version control, also…
