Oracle is hosting a number of Welcome Sun events worldwide, starting on early March going through end of April. The events cover cities in all continents; the full list is at the Oracle webpage.

Some selected cities cover Identity Management, SOA, Enterprise Java, GlassFish and AppServer Directions; these are marked with "*" in the page (21 as of this writing).

Detailed event information is already available for some of the cities (e.g. Madrid, on March 17th), I assume others will show up as the dates near.
