-- Main.hyperic - 02 Apr 2007 Charles Lee, VP of Engineering at Hyperic, will explain how Hyperic engineers took PostgreSQL, an open source database, and scaled it to handle the load of Hyperic HQ, a Java-based Open Source systems management project. Charles will discuss PostgreSQL^? performance tuning, and the difference between EJB and Hibernate. Scaling Open Source components to meet the reliability and feature needs of customers is quite a challenge, regardless of which tools are used.
