2. 1 My Soldiers turn up for a fight 1 The Critical systems have to be available to run the business There are “two” demands I press upon my Armies There are “two” requirements a business demands from the IS department 2 They are in a condition to put up a fight when they get to the battlefield 2 The core applications are in a usable condition

3. ILM – A term well used Information Lifecycle Management " Information lifecycle management (ILM) is a process for managing information through its lifecycle, from conception until disposal, in a manner that optimizes storage and access at the lowest cost. " Source: IBM – Compliance and Data Retention

4. Initial input Day to day Operational Nearline & Off-line End of life Replication & HA System Management Data Management Information Information Lifecycle Management

5. Maintenance Window diminishing Attended operations Lack of technical expertise Lack of in depth object/job information DASD utilization – No hardware budget Application performance – No Hardware budget Constant fire fighting SOX Compliance The Pain…

6. Timeslice Optimization Dynamic Pool Sizing Mirroring Cache Activity Levels Performance tools PRIORITY ASSIGNMENT Automatic Performance Adjustment The Obvious Assumptions

7. Identifying the problem Downforce Turbo Pressure Tyre Selection Damper settings

8. Start with the fundamentals! Identifying the problem

9. The Fundamentals

10. Relative % of disk space saved Small input, Big gains

11. Business Benefits Save valuable operator time Reduce human error & fear factor Improve interactive performance Improve batch performance Improve HA performance Reduce tape backup window Reduce disk utilization Improve disk capacity planning Task Object cross referencing Physical file optimization Logical file optimization Program optimization Object optimization Object & spool file archiving iSeries “Make the most of what you already have” Small input, Big gains

12. Regular (Weekly) capture of object information All files All Members All Program objects Other objects Clearly date stamp Strip out non-essential information Remember, QSYS is only one part of IFS For the brave… Job information tracking Store history Reference reporting – today Vs. last week etc. Capacity Planning

14. Business Benefits Save valuable operator time Reduce human error & fear factor Improve interactive performance Improve batch performance Improve HA performance Reduce tape backup window Reduce disk utilization Improve disk capacity planning Task Object cross referencing Physical file optimization Logical file optimization Program optimization Object optimization Object & spool file archiving iSeries “Make the most of what you already have” Small input, Big gains

15. Intelligent when reorganizing files Deleted records take up disk space and slow down file access Re-Org’s can take a long time Re-Org’s can NOT be stopped once started Users do NOT have access to the files during Re-Org Analyze files and estimate how long it will take If there is enough free time re-org the files using RGZPFM If there is not enough time use the active Re-org feature (5.4 onward) –take care Small input, Big gains

16. Physical files will have many deleted records which take up disk space and slow down the application Shuffle moves active records to top of file while users remain on-line Truncate to free disk space RIP Benefits Shuffle by arrival sequence or from any (fastest) No exclusive file locks during shuffle IBM supplied facility is not end-to-end solution Program in Start/stop of shuffle when so you can manage it Program in separate Truncate function File Reorganization While Active Small input, Big gains

17. Business Benefits Save valuable operator time Reduce human error & fear factor Improve interactive performance Improve batch performance Improve HA performance Reduce tape backup window Reduce disk utilization Improve disk capacity planning Task Object cross referencing Physical file optimization Logical file optimization Program optimization Object optimization Object & spool file archiving iSeries “Make the most of what you already have” Small input, Big gains

18. Logical File Optimization Access paths consume lots of disk space Redundant access paths cause performance overhead Duplicate access paths exist on most systems Capture and store keys and usage information Analyze access paths, share duplicate access paths Files that are rarely or never accessed can have maintenance changed to re-build Small input, Big gains

19. Business Benefits Save valuable operator time Reduce human error & fear factor Improve interactive performance Improve batch performance Improve HA performance Reduce tape backup window Reduce disk utilization Improve disk capacity planning Task Object cross referencing Physical file optimization Logical file optimization Program optimization Object optimization Object & spool file archiving iSeries “Make the most of what you already have” Small input, Big gains

20. Program Optimization Compression Rapid compress and decompress infrequently used programs or symbol table Program Optimization Makes program run faster Removes redundant logic & instructions Program Before Program After Symbol Table Compression Program After Full Compression 50,000 Programs on iSeries/i5 is very common

21. Business Benefits Save valuable operator time Reduce human error & fear factor Improve interactive performance Improve batch performance Improve HA performance Reduce tape backup window Reduce disk utilization Improve disk capacity planning Task Object cross referencing Physical file optimization Logical file optimization Program optimization Object optimization Object & spool file archiving iSeries “Make the most of what you already have” Small input, Big gains

22. Output queues Job queues Message queues History logs Problem log Distribution log IBM journals Alerts Physical files Logical files Programs Office documents On line education files Compress device files Compress menus Compress panel groups Reclaim temporary storage Reclaim unused spool member space Resize oversized objects Delete replaced objects “Wow…I didn’t know there was so much you could do.” Small input, Big gains

23. Business Benefits Save valuable operator time Reduce human error & fear factor Improve interactive performance Improve batch performance Improve HA performance Reduce tape backup window Reduce disk utilization Improve disk capacity planning Task Object cross referencing Physical file optimization Logical file optimization Program optimization Object optimization Object & spool file archiving iSeries “Make the most of what you already have” Small input, Big gains

24. Archiving “Purging is not the same as archiving” For objects and spool files Use cross referencing to select Move objects to archive library Saved to media when your ready RETAIN A HISTORY Restore on-demand Small input, Big gains

25. Disk is Cheap Processor is Cheap Skills are Scarce Cost Capacity Cost Performance SkillsComplexity ROI Pitfalls

26. Relative % of disk space saved Small input, Big gains

27. Catalogue ALL objects (INCLUDING ALL IFS) Highlight usage…and NON usage! Reorganize and re-sequence Optimize all logical file usage Compress infrequently used objects Optimize programs Reclaim resources Clear down logs/tables Purge/Archive data……. Core Necessities

28. Improved DASD utilization Improved record access Reduced backup time Greatly improved DR More overnight window Faster Query and SQL processes Firm foundation for tuning Better Visibility Improved Capacity and Performance to accommodate Replication/HA -More Free disk! -Improved performance! Benefits

29. Case Studies to be added

30. Disk is cheap! I already do all that It can't be true, you can't do all that safely I already have a product that does that What does IBM Rochester think? What will my IBM Business Partner think? Recovery Implications!! What are the alternatives? FUD

31. Information Automation Simplicity Growth Performance Continuous Regular Ease of use Generics Summary
