Docker, Oracle Images and Cloud

Overview

Oracle is embracing Docker – just like many other companies – as the de-facto standard in Container technologies. It has resulted in the certification of various Oracle products for running in Docker containers and even Oracle supported Docker images are available. Furthermore, Oracle offers 2 Cloud Service around containers: the Container Cloud Service is a generic service that offers a platform for running your containers. Next to that, Oracle offers the Application Container Cloud (more...)

LEAP#308 Combinational Logic 7-segment LED Driver

Ben Eater published a fantastic video/tutorial on designing a 7-segment hex decoder as an adjunct to his 8-bit breadboard computer quest. The first thought was of course “that’s an awful lot of work just to drive a 7-segment display .. lucky we don’t have to do that these days!” My next thought was naturally: “OK, now let’s build it!”. It was in fact a great excuse to dust off some combinational logic methods. As (more...)

New Blog "Clouds and Databases"

Dear Friends,

I have started to write on a brand new blog "Clouds and Databases" that I created recently.

On the new blog, I will be writing about different cloud technologies and databases. Please also join me there if interested in the cloud.

The blog address is http://cloudsanddatabases.blogspot.com and this is how it looks:

Joining Accenture Enkitec Group

I have accepted an offer by the Accenture Enkitec Group to join them starting next month. That unit is a kind of ‘special force’ inside the large Accenture Corporation with particular expertise in Oracle Database and Oracle Engineered Systems technology.

Although I feel quite a bit sad to leave Oracle after all those years, the opportunity to work together with all these bright people – you can see some of them here – outshines that (more...)

Using CSS Frameworks with Fluid

Unlike PeopleTools Classic, which used almost-pixel-perfect layout, Fluid uses CSS for layout. The benefit of this pattern is flexibility. Unlike Classic pages, which only allowed for one layout, Fluid allows us to manipulate layout with CSS. I like CSS, so I see this as a positive. The more content Oracle development delivers in CSS, the more we can configure and transform the user experience. While I may love what I can do with CSS, (more...)

ACE Alumni

Today, I asked Oracle to move me from Oracle ACE Director status to Oracle ACE Alumni status.  There are a number of reasons why I decided to change status.  When I started answering questions on internet forums years ago, I did it to share what I had learned in order to help others.  The same goes for this blog which I originally started so that I could give better and more complete answers to questions (more...)

O7_DICTIONARY_ACCESSIBILITY and UTL_FILE_DIR in Oracle 12c release 2

I was not in the beta program for Oracle database 12c release 2 but when I was discussing security changes in the new release with some people who were in the beta they told me that O7_DICTIONARY_ACCESSIBILITY and utl_file_dir parameters....[Read More]

Getting Started With Proxmox HTTP API Commands

Proxmox has 2 API access points that can be used to control your Proxmox server and virtual guests. One of the API access points is using the command line, which you’re likely already familiar with. The other is the HTTP web API which is exposed as part of the WEB GUI on port 8006. The

Parse Proxmox Web API authentication ticket and the CSRFPreventionToken in Bash

The Proxmox Web API can perform any actions available in the front end Web. By implementing a REST API, all commands have been exposed and can be used programatically. The API is secured using a token based method which provides a ticket that must accompany all API requests except for the request that generates the token. The

255 Again!

There’s so many things that can go wrong when you start using tables with more than 255 columns – here’s one I discovered partly because I was thinking about a client requirement, partly because I had a vague memory of a change in behaviour in 12c and Stefan Koehler pointed me to a blog note by Sayan Malakshinov when I asked the Oak Table if anyone remembered seeing the relevant note. Enough of the roundabout (more...)

SCAP OVAL SQL57_TEST Example For Oracle E-Business Suite

Last week I posted a blog introducing SCAP and OVAL. Here is a quick follow-up with a link to a sql57_test example using the Oracle E-Business Suite - it will suffice for any Oracle database.

A great book to read first on SCAP titled ‘Security Automation Essentials’ for $15 on Amazon is a must read:  https://www.amazon.com/Security-Automation-Essentials-Streamlined-Communication/dp/0071772510. I would highly recommend this book to anyone interested in SCAP and much thanks to Witte, Cook, Kerr and Shaffer (more...)

SQL Tuning Advisor against sql_id’s in AWR

We were in a situation very recently to run SQL Tuning Advisor against a bunch of SQL statements that appeared in the AWR's ADDM recommendations report. The initial effort to launch SQL Tuning Advisor against the SQL_ID couldn't go through as the SQL was doesn't exists in the shared pool.

Since the sql_id was present in the AWR report, thought of running the advisory against the AWR data, and found a very nice and precised (more...)

LEAP#307 Boldport Matrix Keypad Control

So… ways to get arbitrary messages onto the Boldport Club Matrix? I happen to have a KeyboardMatrixModule that is coincidentally 5 keys high by 4 wide .. a number that neatly fits into the 24x5 display port of the Matrix. So I’ve wired it up and enabled a couple of commands to edit a message and start it scrolling. It is somewhat tedious, but it works! As always, all notes, schematics and code are in the (more...)

Oracle SuperCluster M7 SLOB LIO Tests vs Intel Xeon E5-2699 V4

Here are some SLOB LIO figures from a DB zone configured with 16 threads running on an Oracle SuperCluster M7 hardware. For comparison I've also included numbers from an Intel Xeon E5-2699 V4 CPU.

It makes sense to mention that this is not exactly a fair comparison -- a single SPARC M7 core has 8 threads associated with it so my zone is able to utilize a total of two SPARC M7 cores (16 threads (more...)
