Parallelism was first introduced to DB2 way back in 1993 with DB2 Version 3. With every release of DB2 parallelism has been enhanced. In applications like data warehousing and business intelligence, it's almost a necessity. Yet, a surprisingly large number of customers continue to avoid parallelism when it could offer significant elapsed time improvements. With this presentation, we'll try to debunk the myths that surround using DB2 parallelism. We will discuss a little bit of parallelism's history, how parallelism works, the parameters in DB2 that control parallelism and the affects of the value chosen for those parameters, and how to get the greatest benefits when parallelism is put to use; the DOS & DON'TS necessary for you to get the most out of DB2's parallelism. We will also discuss the latest enhancements to parallelism and how parallelism can take advantage of zIIP specialty engines.
