The 17th of may 2011 Planboard is organising the 6th version of the Planboard DBA Symposium. The symposium is a whole day event, in Amstelveen near Amsterdam.
There is a wide range of Oracle database topics, including Apex, Oracle GoldenGate, Oracle E-Business suite and Oracle Exadata (presented by me !).
