A/UX, NeXTSTEP, & OS X
+0 Vote Up -0Vote Down

One thing that gets tedious in the IT community and Oracle community is the penchant for Windows only solutions. While Microsoft does an excellent job in certain domains, I remain a loyal Apple customer. By the way, you can install Oracle Client software on Mac OS X and run SQL Developer against any Oracle Database server. You can even run MySQL Workbench and MySQL server natively on the Mac OS X platform, which creates a robust development platform and gives you more testing options with the MySQL monitor (the client software).

Notwithstanding, some Windows users appear to malign Apple and the Mac OS X on compatibility, but they don’t understand that it’s a derivative of the

Amazon EC2 Linux AMIs
+1 Vote Up -0Vote Down

If you use Amazon Elastic Compute Cloud (EC2), you are always given choices of AMIs (by default; there are plenty of other AMIs available for your base-os): Amazon Linux AMI, Red Hat Enterprise Linux, SUSE Enterprise Server and Ubuntu. In terms of cost, the Amazon Linux AMI is the cheapest, followed by SUSE then RHEL. 

I use EC2 a lot for testing, and recently had to pay a “RHEL tax” as I needed to run a RHEL environment. For most uses I’m sure you can be satisfied by the Amazon Linux AMI. The last numbers suggest Amazon Linux is #2 in terms of usage on EC2.

Anyway, recently Amazon Linux AMI came out with the 2014.03 release (see release

Mac Mini to the rescue

In teaching, I had a problem because my students have different base operating systems, like Windows 7, Windows 8, Linux, and Mac OS X. I needed a teaching and lecture platform that would let me teach it all (not to mention support their environments). That meant it had to virtualize any of the following with a portable device:

  • Windows 7 or 8 hosting natively an Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
  • Windows 7 or 8 hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
  • Mac OS X hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE,

Some MariaDB related news from the Red Hat front
+1 Vote Up -0Vote Down

This is a followup to my early post a month ago titled: MariaDB replaces MySQL in RHEL 7 (lots of stuff in the comments). It’s clear that MariaDB’s role is in Software Collections, which is new in RHEL.

Steven J. Vaughan-Nichols writes Red Hat will switch from Oracle MySQL to MariaDB, reports.

Sean Michael Kerner has a video (and writeup) with Denise Dumas, RHEL team leader, who talks about Software Collections, MariaDB, and how

MariaDB in Red Hat Software Collections
+1 Vote Up -0Vote Down

Towards the end of last year, I was asked to investigate the Red Hat Software Collections by someone that popped by one of my talks. SkySQL has been working heavily with Red Hat, and with Fedora 19 shipping MariaDB as a default, it seems like MariaDB is getting even more distribution. The Red Hat Software Collections 1.0 Beta is now available for users of Red Hat Enterprise Linux 6.

From a database standpoint, users now get MariaDB 5.5. I encourage all to try it, as it is an in-situ upgrade. It is described as:

MariaDB version 5.5, which introduces an easy-to-adopt

Maximum Open Files
+0 Vote Up -0Vote Down

Recently I was discussing with some colleagues the possibility of consolidating some MySQL servers. While the servers are not heavily loading (averaging less than 1,000 queries a second) they are pretty large in terms of storage requirements. Each server has roughly 200 databases on each with approximatley 50 tables. Thats 10,000 tables per server.  Each server contains up to 1 terabyte of data so if you consolidated servers at a 10:1 ratio you would have 10 terabytes of data, 2,000 databases and 100,000 tables with 10,000 queries per second average load.

 

Alright, that's a lot. And without testing I don't know if it would work. It probably wouldn't.  But it might. And if it did, it would save the company a significant amount of money.  But, while discussing this,  someone brought up that open files limit might be a

Apache Can't Use Remote MySQL Server When SELinux is Enabled
+0 Vote Up -0Vote Down

I don't know why SELinux problems seem so frustrating. The problem almost certainly is related to the fact that there is frequently no error message. This is exactly the problem I ran into while turning up a new Apache web server on Red Hat Enterprise Linux 6 (RHEL6) with SELinux enabled.

The problem is that SELinux prevents Apache from making network connections by default. This is defined by the SELinux boolean httpd_can_network_connect_db. In order to change this value, issue the following

2012 to be year of Linux domination
+0 Vote Up -1Vote Down

Previously, I’ve called out years for non-desktop Linux in 2008, Linux in both the low and high-ends of the market in 2009, ‘hidden’ Linux in 2010 and last year, cloud computing in 2011. For 2012, I see continued growth, prevalence, innovation and impact from Linux, thus leading to a 2012 that is dominated by Linux.

A New Platform Supported
+0 Vote Up -0Vote Down

Ever hear of Red Hat Enterprise Linux 6.0? It was released on November the 10th of 2010 . . just over a year ago. In the last couple of days Oracle released the latest version of MySQL Server (5.5.18). Along with the bug fixes, etc they released RPM packages that cover RH EL 6.

Finally. A year later.

Not one given to griping, but really..does it take that long to roll packages for the new version? There were no significant changes in the operating system..in fact the RH EL 5 packages worked on RHEL 6 from my (albeit) limited experience with the combination.

I don't jump onto new versions of operating systems as soon as they come out. I prefer to let others be my beta testers before I put something into production. However, waiting a year seems a bit extreme for this release.

Even so, it's out now so enjoy! Now we have no excuse for not deploying 5.5.

Got open source cloud storage? Red Hat buys Gluster
+0 Vote Up -0Vote Down

Red Hat’s $136m acquisition of open source storage vendor Gluster marks Red Hat’s biggest buy since JBoss and starts the fourth quarter with a very intersting deal. The acquisition is definitely good for Red Hat since it bolsters its Cloud Forms IaaS and OpenShift PaaS technology and strategy with storage, which is often the starting point for enterprise and service provider cloud computing deployments. The acquisition also gives Red Hat another weapon in its fight against VMware, Microsoft and others, including OpenStack, of which Gluster is a member (more on that further down). The deal is also good for Gluster given the sizeable price Red Hat is paying for the provider of open source, software-based, scale-out storage for unstructured data and also as validation of both open source and software in

Red Hat considering NoSQL/Hadoop acquisition
+0 Vote Up -0Vote Down

InternetNews.com yesterday published an article based on an interview with Red Hat CEO Jim Whitehurst asking the question “Is Red Hat Interested in the Database Market?”

In truth there was no real need to ask the question, as Whitehurst’s comments made it pretty clear that Red Hat is interested in the database market, and specifically the NoSQL database market.

“When I say I don’t want to be a database company, I’m saying that I don’t want to be a SQL database company,” Whitehurst said.

In case the implications of that statement were not entirely clear, he later added:

“But we would be very interested in a NoSQL type database or Hadoop type thing,” Whitehurst said.
