  1. 1. Managing Db2 Workloads2020
  2. 2. Core Problem Excess CPU and IO usage by transactions High costs to run customer workloads Loss of performance of customer workloads Friction in your stakeholder relationships, due to the above _1 The Problem We Will Solve
  3. 3. Understanding the Problem: The Snowball Effect The Harsh Truth o Creating a well-balanced, well-configured system is not enough o ALL performance issues must be discovered, identified, and fixed ASAP Modern environments are complex, and interdependent ○ All workloads share and occupy system resources ○ Transactions depend on each other to execute properly One small problem can create multiple big problems. ○ On inefficient transaction occupies too many resources... ○ Other transactions are delayed until those resources are free... ○ Workloads are not executed, leading to systemic failures _2
  4. 4. There Are No 100% “Stable” Environments New Business Requirements New Business Requirements Modernization of Workloads Introduction of New Technologies Modernization of MethodologiesAdaptation to New Software Versions Modernization of Development Tools Modernization of Interfaces Growth of Security Requirements The Human Factor Increased Data Volumes A New, Inefficient Transaction Untimely Reorganization _3 Understanding the Problem: The Myth of “Stability”
  5. 5. o SAP GUI, DBA Cockpit o Tivoli Enterprise Portal (TEP) o Specialized, powerful tools o Can identify and solve many performance issues o There are issues that these solutions cannot discover, identify, and fix o Remember: Only one of this issues can “Snowball” into a systemic problem Commonly Used Conventional Solutions What These Solutions Do Well Where These Solutions Fail _3 Understanding the Problem: Conventional Solutions
  6. 6. What Happens When Conventional Solutions Fail When conventional solutions encounter an issue they can’t solve, you might: ● See the performance problem, but fail to recognize its root cause ● Recognize its root cause, but have no idea how to solve it ● Know how to solve it, but lack the technical skills to apply the fix ● Apply the fix, but fail to actually generate performance improvement _4
  7. 7. Ultimately, conventional solutions are useful, but insufficient. They: • Cannot discover, identify, or fix all performance issues • Require multiple tools and dedicated technical support teams • Create a flood of alerts— many of which are false positives • Create a flood of alerts— many of which are false positives htttps://.pngtree.com/so/характерhtttps://.pngtree.com/so/элемент _5 Conventional Solutions: Fundamental Flaws
  8. 8. Discovers, identifies, and fixes problems ignored by conventional solutions Consolidates tools, and reduces the burden on technical support teams Reduces alerts and false positive— especially repeating alerts Moves you into a proactive mode of addressing issues before they blow up, while improving your environment’s fundamental health and performance _6 The Need for a New Solution
