Bloggers Meetup @ Oracle OpenWorld 2010

It’s that time of the year again — Oracle OpenWorld time — and it’s my pleasure to announce our regular Oracle bloggers meetup again this year. We all know that Oracle community has grown this year so we expect to see folks from all the different technologies including MySQL, Java, Sun hardware folks in addition to the core Oracle database and apps crowd.

Michigan OakTable Symposium (MOTS)

Michigan OakTable Symposium (MOTS) is a unique event taking place just before Oracle OpenWorld — 16-17 September. Why unique? This is the first conference (is it not?) where all presenters are members of OakTable Network, a group that gathers number of like-minded IT professionals with scientific approach to Oracle database technology and to the life in general.

Exadata Technology Blogs

I hear lots of feedback on Exadata front asking for more and more technical information and I often refer them to some material online.

ODTUG Kaleidoscope 2010: Best Practices

For me, ODTUG Kaleidoscope 2010 started on Friday with the ACE Directors briefing. Best practices topic was touched there slightly and I twitted about it.

Oracle UTF8 Encoding and String Manipulation Overhead

These type of projects are coming up again and again so I think it must be common for many of you. Thus, this bit might be useful. This is the PL/SQL block I came up with

APEX — Bulk Images Upload Using EPG

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:
