Due to the division of responsibilities between DB2 and z/OS staff, it is often neglected and can become the weakest link in your on demand infrastructure goals. The speaker, from the IBM Dallas Systems Center, has performed over 30 of them in the last 6 years for large parallel sysplex users in the Americas. She describes the obstacles she observed and provides recommendations for achieving high availability targets.
