Abstract: Each release of the Oracle RDBMS is associated with dramatic improvements in PL/SQL performance. However, the ultimate performance of any PL/SQL program is still in the hands of the PL/SQL programmer. In this presentation we’ll examine trends in PL/SQL performance, look at tools to identify and tune problematic PL/SQL and examine PL/SQL performance best practices. Topics will include opportunities for improving SQL performance by using PL/SQL code, measuring and diagnosing PL/SQL performance issues, best practices for writing high performance PL/SQL and the use of new 11g optimizations to further turbo-charge application code.
