IMS UG 2013 - IMS Configuration Manager.

  1. 1. IMS Configuration Manager Introduction IMS Regional User Group Columbus, OH 10/8/2013 Rick Engel IMS Tools – Technical Sales and Support © 2013 IBM Corporation
  2. 2. Today - Typical Concerns and Challenges  Increased use of data assets Bigger database size Higher demands for continuous data availability (24x7 needs)  New business requirements Enabling host data for access outside of the zSeries (host) platform New governmental regulations  Cost containment Reduce CPU, I/O, and elapsed execution times Budgetary Concerns  Support staff concerns Head count reductions Retirements Experience and knowledge level The “shrinking skill set” - A top concern for all 1 © 2013 IBM Corporation
  3. 3. The “Shrinking Skill Set” – Some observations Issue: The “z” support community is getting older which creates an impending skills problem that IT organizations are already beginning to deal with Facts:  80% of IMS DBAs are over the age of 55   Within the next 10 years, this entire group will be moving on to retirement Most companies have IMS DBAs with 25+ years of experience  Estimates are it takes 5-7 years for someone to become a truly effective DBA  Industry statistics show that on average, new employees will remain on the same job for between 3-5 years Response:  IT organizations have some “big shoes to fill”  Provide tools that can capture the wealth of experience  Put new tools into place to accelerate the learning curve for next generation IT support people 2 © 2013 IBM Corporation

IMS Configuration Manager Components: Distributed access Resource Manager Parameter Management Repository (ICM) PROCLIB controls Intelligent Installer History Eclipse GUI Connection Server Utilities • Take-up • Gen • Copy Parameter editor Product focus: • Management of IMS parameters • Management of IMS system resources (DRD and traditional SYSGEN) • Operations management, understand and debug possible resource definition errors 4 © 2013 IBM Corporation
  6. 6. IMS Configuration Manager Modernize IMS parameter management • How do you… – reduce the risk of changing settings that have not been altered in years? – identify differences across systems and LPARs? – • Logical search Edit View ensure a high-level of operational integrity with less experienced staff? Learn Manage learn about and apply new settings and parameters? – • • Smart editor • Help • Validation IMS Configuration Manager helps you control, audit, and validate the parameter definition process • Enterprise view of resources • History record of all changes Making parameter changes – Is it “Risky Business” for your organization? 5 © 2013 IBM Corporation
  7. 7. IMS Configuration Manager Streamline resource management with DRD • DRD offers the promise of a modern approach to application development and management – Reduces the need for performing an IMSGEN – More flexible and immediate than an online change • But can you retain processes, control, and structure you have developed over years? • IMS Configuration Manager Complements DRD; retains benefits of both approaches Dynamic resource definition (DRD) Alternative to IMSGEN Immediate Simple Flexible IMSGEN Batch system definition process, with online change process Structured Controlled Organized IMS Configuration Manager adds structure to the DRD process. – Maintain your processes but gain the benefits of DRD – Add a layer of audit and control that allows you to open up the process to developers – Automation and reversibility of change process 6 © 2013 IBM Corporation
  8. 8. IMS Configuration Manager IMS Configuration Manager - GUI • Control and manage IMS systems • Learn and discover the Type 2 commands that are essential to managing your IMS resources • List and view resources in the IMS Configuration Manager repository and active IMS systems definitions • Use compare features to highlight differences between environments • Integrates with IMS Explorer – Provides an environment that makes it easier to develop IMS applications and understand PSB and DBD definitions – Better visualization of definitions and changes, and help understanding and building IMS commands 7 © 2013 IBM Corporation

  24. 24. IMS Configuration Manager Summary conclusions • IMS Configuration Manager simplifies the management of IMS resources and parameters – Using DRD or traditional SYSGEN processes • Provides the same level of controls you had in a SYSGEN environment • The resource installation process is streamlined making it easy to synchronize offline source with online systems • The availability of rollback helps customers introduce changes as a unified set • Back out provides auditors with peace of mind • IMS Configuration Manager provides a foundation from which an end-to-end IMS administration and management system can evolve “Can you use some planning help for in DRD?” 23 © 2013 IBM Corporation
  25. 25. IMS Configuration Manager Migration to IMS DRD Planning Workshop: • DRD means “Dynamic Resource Definition” ‒ Available since IMS V10: Designed to allow for non-disruption of IMS systems in order to implement system resource changes (Ex: programs, transactions, databases, terminal devices) ‒ Fact: Most IMS customers have not taken steps to implement DRD. Why is that ?   Can be a ‘complex task’, careful planning and implementation needed  • Skills challenged and resource shortage, not ‘enough’ time “Fear factor” – a major change in their approach to managing IMS systems Messages delivered: ‒ The DRD advantage: Provide confidence and motivation to the customer for moving to use DRD ‒ Education on the migration process, provide guidance to the customer on steps to undertake ‒ The IMS Configuration Manager tool is designed to provide an ‘ease of use’ path to DRD and the functionalities for the administration and tracking of ‘dynamic change’. • Multitude of session topics are available: ‒ 24 Agenda is customized to a customer’s specific interests and needs © 2013 IBM Corporation
  26. 26. IMS Configuration Manager IMS and DB2 Backup and Recovery Workshop: • Some basic “pain points” addressed: ‒ Needs for coordinated IMS and DB2 application backup and positioning data recovery to a common ‘synched’ point-in-time ‒ Reduce total spend (including CPU cost) on backup-type processing  • Fact: Majority of customer spend on data management processes on z is in ‘backup processing’. Typically at 60-70%, what is their ROI on this spend ? Messages delivered: ‒ Value in ‘centralized control’ of data backups ‒ Importance of tested disaster (DR) and local recovery methodologies ‒ Local application recovery and DR solutions are tied together ‒ Coordinated IMS and DB2 recovery to a consistent point in time ‒ Value emphasis on IBM Tools participating in ‘Storage Mirroring’ environments • Multitude of session topics are available: ‒ 25 Agenda is customized to a customer’s specific interests and needs © 2013 IBM Corporation
  27. 27. IMS Configuration Manager Migration to IMS HALDB Planning Workshop: • HALDB means “High Availability Large Database” ‒ Available since IMS V7: Designed to allow for a partitioned database structure to address needs of larger database sizes. Works to promote higher database availability by segregating data in key ranges by partition. ‒ Fact: Most IMS customers have taken steps to leverage use of HALDB. Have you? No ? … Why not?   Can be a ‘complex task’, thoughtful planning and implementation needed  • Skills challenges, not ‘enough’ time “Fear factor” – a major change in their approach to managing IMS systems and applications Messages delivered: ‒ ‒ 26 Education on the migration process, provide guidance to the customer on steps to undertake ‒ • The HALDB advantage: Provide confidence and motivation to the customer for moving to the use of HALDB databases The HALDB Toolkit tool is designed to provide an ‘ease of use’ migration path to HALDB DRD and functionalities for the subsequent administration of HALDBs Agenda is customized to a customer’s specific interests and needs © 2013 IBM Corporation
  28. 28. IMS Configuration Manager Mining for MIPS: • Some basic pain points addressed ‒ IMS is the ‘work horse’ database engine in our environment, how do I ensure that performance is at its optimum level ?   ‒ Long running IMS batch processes have impacted our SLAs, online data availability  ‒ Do I have a ‘tuning’ opportunity ? How do I identify areas of potential improvement ? Growing overall CPU usage is creating financial pressures to our budget and organization  ‒ What means are there for performance measurement, trend analysis, ‘bottleneck’ identification ? Dynamic IMS buffer pools in V13, how can I take advantage of this ? Where am I spending “CPU” ? How can I address this critical business concern ? Messages delivered: ‒ Working to ensure the optimization of business applications using the IMS DBMS is a continuous process; performance degradation is a by-product if this task is taken lightly or ignored ‒ IBM’s IMS Tools provide many capabilities that are designed to address the common concerns and needs in IMS for ‘performance and tuning’ • Multitude of session topics are available: ‒ ‒ 27 Agenda is customized to a customer’s specific interests and needs Can be combined with DB2 topics as well © 2013 IBM Corporation
