was recently installing one APEX application and needed to upload a bunch of images. APEX was configured to use EGP (Embedded PL/SQL Gateway) so traditional options were to configure FTP or WebDAV but I’d rather not open these services on production environment. Our resident APEX expert pointed me to the installation process and suggested there is a simple way to do that using a single PL/SQL call. It turned out that it was more than a single PL/SQL call involved but nothing too difficult. What you need is to create the hierarchy of files and directories that you want to upload (images or not – doesn’t matter). Then you create an XML file imagelist.xml listing required directories and files to upload. Here is the example:Read More >
So how does an Oracle DBA go about learning MySQL?
Obviously you start by reading the docs. Specifically, I looked for the MySQL equivalent of the famous Oracle “Concepts Guide”.
Unfortunately, it doesn’t exist. I couldn’t find any similar overview of the architecture and the ideas behind the database. The first chapter of “High Performance MySQL” had a high level architecture review, which was useful but being just one chapter in a book, it lacked many of the details I wanted to learn. Peter Zaitsev’s “InnoDB Architecture” presentation had the kind of information I needed – but covered just InnoDB.
I recently reformatted my laptop with the latest Ubuntu LTS release, 10.04, aka Lucid Lynx. Since I like to have a native client installation as well as a portable sandbox server, I decided to install the latest version of Oracle EE, 22.214.171.124. Rather than re-invent the wheel, I’m going to direct you to the previous Oracle-on-Ubuntu post by my colleague Augusto Bott. Many of the directions there hold true here (even with 32-bit vs 64-bit), with a few exceptions.Read More >

One of the first questions that I asked myself when EM GC 11g came out is how would a silent installation go especially taking into account the use of WebLogic server as the http server. But before any attempt of silent installation I started the GC 11g GUI installation to local VM machine
(Oracle Enterprise Linux 5.4 64-bit) with an allocated 2Gb of memory and got errors since WebLogic server was not installed there.
If you have ever had this message: Unable to locate an oracle.mk, proc.mk or other suitable *.mk file in your Oracle installation. (I looked in…) It can be a very frustrating one to track down. There is no 100% answer for this problem but there seems to be two main scenarios where I have encountered this and have come up with somewhat of a solution, here it is.Read More >
I cloned Oracle software before and it is a simple process: tar $ORACLE_HOME, copy the tar file to the new server, untar, run the cloning script which will register the new home with the inventory, and you are done! In theory, at least. Here is what actually happened:Read More >
