How To Succeed In Presales?

success-and-failure

This article is aimed at anyone considering making the move into technical presales who currently works in a professional services, consultancy or support role, or as customers and end-users. You will notice that the title of the article has a question mark at the end – that’s because I don’t have the answer – and I have neither the confidence nor the evidence to claim that I have been a success. But I have made lots (more...)

The Ultimate Guide To Oracle with Advanced Format 4k

fud

It’s a brave thing, calling something the “Ultimate Guide To …” as it can leave you open to criticism that it’s anything but. However, this topic – of how Oracle runs on Advanced Format storage systems and which choices have which consequences – is one I’ve been learning for two years now, so this really is everything I know. And from my desperate searching of the internet, plus discussions with people who are usually much knowledgeable than (more...)

A New Approach To My Blogroll

Like most people, I have a panel on the right hand side of my blog which contains my blogroll, i.e. a list of links to the blogs of other people I respect and admire. And like most people in the Oracle world, up until today it was full of the same names you always see. To pick three examples:

New installation cookbook for SUSE Linux Enterprise Server 11 SP3

Exactly what it says on the tin, I’ve added a new installation cookbook for SUSE 11 SP3 which creates Violin on a set of 4k devices.

I’ve started setting the add_random tunable of the noop I/O scheduler because it seems to give a boost in performance during benchmarking runs. If I can find the time, I will blog about this at some point…

Postcards from Storageland: Two Years Flash By

calendar

The start of March means I have been working at Violin Memory for exactly two years. This also corresponds to exactly two years of the flashdba blog, so I thought I’d take stock and look at what’s happened since I embarked on my journey into the world of storage. Quite a lot, as it happens…

More Problems with Oracle’s Support of 4k Devices

This is going to be another one of those posts, a bit like this one, that discuss the use of Oracle’s database product with Advanced Format devices. I wish there weren’t so many of these posts, but it seems that Oracle has a lot of issues with it’s implementation of 4k support.

Oracle ASMLib: Physical and Logical Blocksize

This article is about the use of Advanced Format devices on Oracle’s ASMLib kernel library for Linux. For background, read this page on 4k sector sizes first, otherwise it might all sound like nonsense. Mind you, it mind sound like nonsense anyway, I can’t guarantee anything here. By the way, a big hello to my buddy Nate who asked for this information: you rock, dude.

In more recent versions of ASMLib, Oracle introduced a new (more...)

Oracle AWR Reports: Understanding I/O Statistics

truth

One consequence of my job is that I spend a lot of time looking at Oracle Automatic Workload Repository reports, specifically at information about I/O. I really do mean a lot of time (honestly, I’m not kidding, I have had dreams about AWR reports). One thing that comes up very frequently is the confusion relating to how the measurements of IOPS and throughput are displayed in the AWR report Load Profile section. The answer, (more...)

New script for setting up multipath.conf entries

I’ve added a new script to the Useful Scripts page called setup-violin-mpath.sh which automates the process of creating entries for the /etc/multipath.conf file on Red Hat 6 / Oracle Linux 6.

As the name suggests, I wrote it with Violin devices in mind, but there should be overlap with other storage which will potentially make it useful elsewhere… see here for more details.

Oracle Fixes The 4k SPFILE Problem…But It’s Still Broken

As anyone familiar with the use of Oracle on Advanced Format storage devices will know to their cost, Oracle has had some difficulties implementing support of 4k devices. Officially, support for devices with a 4096 byte sector size was introduced in Oracle 11g Release 2 (see section 4.8.1.4 of the New Features Guide) but actually, if the truth be told, there were some holes.

Printing Attachments in Oracle 12.2: How does it Stack Up?

With the release of EBS 12.2, Oracle is making the claim that they have improved the attachment printing process. After reviewing the integration, I completely disagree; they have not given users a better solution.  No matter how you slice it, Oracle EBS customers are no further ahead with (more...)
