Server Problem : A Resolution?

AWSIt’s been a pretty annoying couple of days on the website server front.

The server locking up intermittently is one thing, and for all I know, maybe my fault? The incompetence of the hosting company is quite something else.

Just so you are aware why I was doing my nut yesterday, the hosting company had disabled my ability to force a power cycle of my dedicated server while they did a hardware test. They forgot to (more...)

Server Problems : Update

hard-disk-42935_640This is a follow on from my server problems post from yesterday…

Regarding the general issue, misiaq came up with a great suggestion, which was to use watchdog. It’s not going to “fix” anything, but if I get a reboot when the general issue happens, that would be much better than having the server sit idle for 5 hours until I  wake up. 🙂 Let’s see how that works out…

Praveen asked if I use any tools (more...)

Server Problems : Any ideas?

I’m pretty sure last night’s problem was caused by a disk failure in the RAID array. The system is working now, but it might go down sometime today to get the disk replaced. Hopefully they won’t do what they did last time and wipe the bloody lot! 🙂

The subject of this post is not about this specific incident, but more generally about what I’ve experienced over recent weeks/months.

WordPress 4.5 Released

WordPress 4.5 “Coleman” has been released.

I just applied it to the five WordPress sites I manage by manually triggering the auto-update and everything went through fine.

There are some updates to the standard themes that you will need to manually trigger for update, but there was no drama there either.

I fully expect a rash of little updates to get released over the coming days as new bugs are spotted. 🙂

Happy upgrading. 🙂

Cheers

Provisioning Virtual ASM (vASM)

Create vFiles

In this post, we’re going to use Delphix to create a virtual ASM diskgroup, and provision a clone of the virtual ASM diskgroup to a target system. I call it vASM, which is pronounced “vawesome.” Let’s make it happen.

That UX “Rockstar” Metaphor Is So Over. Fashtechista Fits.

I hate that “rockstar” tech industry metaphor.

The next time you hear that so-and-so is a “total UX rockstar” or about some other tech head being accorded the status, well here comes the real comparison to make:

Lenny Kravitz is a rockstar. Phil Lynott (God bless him) was too.  People who work in UX and tech are not.

Period.

That said, if UX designers need to adopt any popular metaphor that resonates more accurately with (more...)

Real Push Button Refresh with Raspberry Pi

Push Button

In this post, we’re going to perform a push button refresh of an Oracle Database, Application Express (APEX) installation, and Tomcat webserver.

“But Oracle Alchemist,” you’re probably thinking, “we know about that. You’ve told us about how Delphix can provision and refresh data.” And yes, you’d be right. But I wasn’t done yet.

We’re going to perform a refresh of an Oracle Database, APEX installation, and Tomcat running in Amazon Web Services, replicated from (more...)

Managing your Database in a Zombie Apocalypse

Zombie Server Room

Only two things are really certain: network latency over long distances, and the fact that humanity will soon rapidly degenerate into undead brain-eaters.

When that day comes, when the dead are crowding at your door and the windows are busted out and ripped up rotted arms are clawing at the inside of your home, I know what you’ll be thinking: is my database protected?

Don’t worry, my friends. The Oracle Alchemist has you covered. We (more...)

Another Great OpenWorld

Steve at the Delphix Booth

Last week I attended Oracle OpenWorld 2014, and it was an outstanding event filled with great people, awesome sessions, and a few outstanding notable experiences.

Personally I thought the messaging behind the conference itself wasn’t as amazing and upbeat as OpenWorld 2013, but that’s almost to be expected. Last year there was a ton of buzz around the introduction of Oracle 12c, Big Data was a buzzword that people were totally excited (more...)

Openworld 2014

Oracle OpenWorld

Are you going to Oracle OpenWorld 2014? I am, and I hope to see you there! As you probably know, OpenWorld is a humongous event with tens of thousands of people in attendance and some amazing presentations. Why, I even hear Oracle’s new CTO might be there. I wonder if he has anything to talk about?

This year we’ll have a ton of activity at the Delphix booth. You can check out the speaking schedule, (more...)

Teach Your Children Well

computerroom

Today’s the first day of school in my city, and the plethora of “OMG 1st day of school!” posts of Facebook and my own kids heading back in to slog through another year of fundamentals got me thinking about education. My own kids (12/daughter and 10/son) came home and went swimming since it was about 104 degrees today…the hottest day of the summer, as it were.

The Customer Experience

The Apple Experience

I’m going to kick this post off by taking sides in a long-standing feud.

Apple is amazing.

There. Edgy, right? Okay, so maybe you don’t agree with me, but you have to admit that a whole lot of people do. Why is that?

Deep Dive: Oracle WebCenter Tips and Traps!

I'm currently at IOUG Collaborate 2014 in Las Vegas, and I recently finished my 2-hour deep dive into WebCenter. I collected a bunch of tips & tricks in 5 different areas: metadata, contribution, consumption, security, and integrations:


As usual, a lot of good presentations this year, but the Collaborate Mobile App makes it a bit tough to find them...

IT Stockholm Syndrome

Shrugging

Random thoughts on a Friday afternoon…

We’ve all got problems. More to the point, every IT department or team has problems of some kind. It’s why we hire consultants, buy products, start long and arduous journeys into the great unknown depths of root cause analysis, and so on.

What fascinates me is the level at which we come to identify with our problems. When I’ve gone into an environment to deliver recommendations, the conversation usually (more...)

WebCenter LDAP Filters Explained!

We recently has a client with some LDAP performance issues, and had a need to tune how WebLogic was querying their LDAP repository. In WebLogic, the simplest way to do this is with their LDAP Filters. While trying to explain how to do this, I was struck by the lack of clear documentation on what exactly these filters are and why on earth you would need them... The best documentation was in the WebCenter guide (more...)

99 Bottles of ADF

Three years ago I blogged about the site 99 Bottles of Beer, which is a site dedicated to generating the lyrics of that oh so annoying song in every programming language known... currently over 1500 languages have been submitted. It's a surprisingly useful excercise when learning a new language... (more...)

Integrating ADF Mobile with Oracle WebCenter

Another talk I gave at Collaborate 2013 is this one on ADF Mobile and WebCenter. It builds off my talk from last year about general techniques, and gets into specific about the new ADF Mobile technology, and how to integrate it with WebCenter content and WebCenter Portal.

Seamless Integrations between WebCenter Content, Site Studio, and WebCenter Sites

At Collaborate 2013 this year, Tony Field and I put together a talk about a topic that has been been floating around the WebCenter community as of late...How do I integrate WebCenter Sites (Fatwire) with WebCenter Content or Site Studio? We put together a handful of integration techniques, but (more...)

JDeveloper Memory And Performance

I was recently doing some training on ADF, and the students were complaining how slow JDeveloper was... Dragging and dropping Data Controls onto a JSF page? It's the pause of death if you will. Not to mention the "Out Of Memory" errors that crop up in the middle of debugging a large app. Very frustrating for developers, so I decided to once and for all get figure out what magic JVM tuning parameters would speed it up.

As a general rule, Java is optimized for throughput, not latency. Once the garbage collector kicks in, performance drops like a rock. A (more...)
