  • 6. Why Autonomics and ModernizationNow more than ever, business challenges demand it! Unanticipated problems may result in downtime and loss of revenue Increased burden of system management and maintenance Problem determination is time and resource intensive – Expert skills are often spent ascertaining when a problem took place rather than figuring out how to fix it DBA resources are expensive and dwindling – Expert skills are wasted on repetitive tasks Time and resources are not available for developing new applications, pursuing new technologies, and growing business6 © 2012 IBM Corporation
  • 7. When problems do occur, the impact can be extensive The database server is in trouble. Why am I I’ll create an incident as soon as I can having these database and work on it. I hope no one is events? Everything affected. seems ok. IT Why are these application Operations DB transactions taking so long?

How often do image copy jobs fail? Is it lack of space or objects not in correct state?

Is storage team already making volume copies of DB2/IMS data? Are you image copying the same object/database many times during a night without you knowing it? Asking for help ? Use RRR Recovery Readiness Do you have control over your backups? Reporter Are incremental copies made? – How many between full copies? – DB2 Merge copy run? – IMS Change Accums? Are these copied to disk or tape? Stacked on tape? Is everything in sync with the ICF catalog? Do you verify recovery on a scheduled basis? Are you taking copies of application spaces – test and production?48 © 2012 IBM Corporation
  • 49. Resource Readiness Reporter RRR is an informative tool that will provide sites with the help they need in the following: 0 – Risk • Reduce risk of data loss by reporting missed backups Rand – Exposure • Reduce exposure for application outage – Costs • Reveal the price of image copies – by examining their resource usage. Analyzes all recovery resources for DB2 and IMS subsystems over a specified period of time. – Note: Resource usage is valid for only DSNUTILB (DB2 image copies). RRR does not report on CPU/IO for vendor utilities. Same for IMS IC for now.
