For the last few months I’ve been presenting a lot in various venues. I presented in Oracle Open World, HROUG conference in Croatia, DOAG in Germany, Oracle Week in Israel (3 day long presentations!), MySQL User Group in Israel and in some more private conferences and private events. I was also accepted to IOUG collaborate in Las Vegas in April and I’m planning to give some Webinars soon.
I believe that educating and sharing (more...)
If you are planning on attending the UKOUG Tech16 event at the Birmingham ICC next week, I am presenting on the subject of flash storage at the following time:
Date: Monday 5th December
Time: 13:10 - 14:00
Title: Flash Storage for DBAs: You can't avoid it anymore
Track: Systems 1
In this session I’ll be discussing why flash storage is something that DBAs need to understand. I will then bestow upon the audience key pieces (more...)
I want you to imagine that you are about to run a race. You have your trainers on, your pre-race warm up is complete and you are at the start line. You look to your right… and see the guy next to you, the one with the bright orange trainers, is hopping up and down on one leg. He does have two legs – the other one is held up in the air – he’s just choosing to (more...)
It’s been some time that I have updated my Oracle blog. The biggest reason for this absence was that I was struggling with the hosting provider of mine. I won’t get into this whether it was good or bad but let’s just say, I wasn’t happy with their services and more so, from their customer support. And I had decided to switch over to a new hosting provider. This new hosting service has better plans, (more...)
On the first or second year after I became a DBA (somewhere in the year 2000, give or take), I heard about this magical event that is taking place in the Oracle realm. All the top Oracle DBAs and professionals in the world (and maybe a couple of unicorns, I’m not sure) are gathering in a small but beautiful village by the name of San Francisco – and talk about databases. I found this story (more...)
Last week, my dear friend Roni Vered Adar told me about a pod cast by Kendra Little entitled “How to Level Up Your DBA Career (Dear SQL DBA)“. Roni told me that Kendra talked about the importance of public speaking and wanted to know what I think.
I said it’s a great idea, so Roni asked if I could tell her a little about how I started speaking in public, and about my (more...)
Today’s storage array market contains a wild variation of products: block storage, file storage or object storage; direct attached, SANs or NAS systems; fibre-channel, iSCSI or Infiniband… Even the SAN section of the market is full of diversity: from legacy hard disk drive-based arrays through the transitory step of tiered disk+flash hybrid systems and on to modern All-Flash Arrays (AFAs).
If you were partial to the odd terrible pun, you might even say that it was a bewildering array of (more...)
I’ve updated my install cookbooks page to include a new cookbook for installation of Oracle 188.8.131.52 Real Application Clusters on Oracle Linux 6.7.
This is also the first one I’ve published since I left the employment of Violin Memory to work for Kaminario, so this install uses a Kaminario K2 All Flash Array. However, it applies very well to any Oracle RAC installation which uses relatively capable storage.
This week I had the opportunity to record a webinar on a subject very close to my heart, the Software-as-a-Service industry. From 2003 to 2007 I managed the production infrastructure for a global SaaS company through the transition from startup to acquisition (partly by Salesforce.com). At the time, SaaS was a relatively new phenomenon, predating any concept of “Cloud”, but the challenges we faced then are still very relevant today.
The company was run by charismatic (more...)
The BI Publisher SIG is gearing up for Collaborate 2016 in April and is looking for volunteers to share their experiences, tricks, tips, challenges, etc… with fellow users during our meeting in Las Vegas on Monday April 11th. Do you have a story to tell? Want to showcase a challenge? Want to brag about an accomplishment? We would love to have YOU, the actual user spend 10-15 minutes sharing your experiences/stories with (more...)
This month sees the four year anniversary of some interesting events. Commonwealth countries around the world celebrated the Diamond Jubilee of Queen Elizabeth II. Whitney Houston was tragically found dead in a Beverly Hills hotel. The Caribbean was hit hard by sargassum seaweed invasion. And I made the decision to leave the comfort of Oracle databases and join the exciting new All-Flash Array industry.
Ok, I might have been stretching the use of the word “interesting” there. But for those with (more...)
About 18 months ago I wrote a post describing the different types of NAND flash known as SLC, MLC and TLC. However, 18 months is a lifetime in the world of technology so now I need to clarify it based on the widespread adoption of a new type of NAND flash. Let me explain…
Recap: 2D Planar NAND
Until recently, most of the flash memory used for data storage was of a form known as 2D Planar NAND (more...)
Sometimes the transition between two technologies is long and complicated. It may be that the original technology is so well established that it’s entrenched in people’s minds as simply “the way things are” – inertia, you might say. It could be that there is more than one form of the new technology to choose from, with smart customers holding back to wait and see which emerges as a stronger contender for their investment. Or it could just be (more...)
Ho ho ho folks. It’s nearly Christmas Day, 2016 and it most definitely is the season to be jolly. It’s also an exciting time in the All Flash Array industry with NetApp announcing its intended acquisition of Solidfire for a reported $870 million. Merry Christmas to everyone at Solidfire!
Unfortunately those sentiments weren’t shared by Pure Storage’s VP of Product, Matt Kixmoeller, who published a blog on the subject of the acquisition which seemed a little on (more...)
This summer I made the decision to leave my previous employer and join another vendor in the All Flash Array space – a company called Kaminario. A lot of people have been in touch to ask me about this, so I thought I’d answer the question here… Why Kaminario?
To answer the question, we first need to look at where the All Flash industry finds itself today…
The Path To Flash Adoption
We all know that disk-based storage has (more...)
First off, if you are not familiar with the term SIG, it stands for Special Interest Group. OAUG facilitates a number of SIGs to bring users together that share common or industries concerning certain Oracle products.
Unfortunately, the BI Publisher SIG has been offline for a number of years and has not been given the attention it needs to be a useful resource for members of OAUG. Well… I’m getting the band back together and (more...)
Recently, I received my annual report from WordPress/Jetpack. I have always enjoyed these reports, so I thought I would make it public.
For the complete report, view it here: PSST0101 – 2014 Year in Blogging
Here’s a couple of excerpts:
Madison Square Garden can seat 20,000 people for a concert. This blog was viewed about 67,000 times in 2014. If it were a concert at Madison Square Garden, it would take about 3 (more...)
Strangest thing happened the other day during a customer upgrade. Our automated scripts were in the process of creating a view and I received the error:
ORA-01720: Grant Option Does Not Exist.
OK….. I get it… BUT…. I didn’t even execute a GRANT statement!? I was just executing a CREATE OR REPLACE VIEW…. what gives?
Doing some searching online, I didn’t find too much that fit my issue. Everyone was getting (more...)
