A bit of history

The latest version of Red Hat Enterprise Linux, one of the most popular and respected Linux distributions in the server market, was released in June 2014, followed by CentOS 7 and Oracle Linux releases in July of the same year.

There are very interesting changes for database …

A/UX, NeXTSTEP, & OS X

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 …

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 …

Mac Mini to the rescue
+0 Vote Up -0Vote Down

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, …

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 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

Maximum Open Files

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. …

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 …
