Larry Youngren attended his first Local User's group nearly 20 years ago. At that time he was still an IBM newbie just getting his feet wet and meeting customers for the first time.
Now, 20 years later, Larry serves as a microcode designer for the lower layers of the eServer iSeries operating system and frequently assists folks who consult with customers regarding High Availability and Journal performance issues.
Since joining IBM in 1976, he has worked exclusively with the microcode, first for the S/38 and now for the iSeries. He has led the teams responsible for Data Base, Commit, Checksums, System-Managed-Access-Path-Protection, and Journal.
His current assignment involves future performance and recovery improvements affecting journaling and Save-While-Active. He and his team have recently authored an IBM Redbook entitled "Striving for Optimal Journal Performance".
