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

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

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?
– learn about and apply new settings and
parameters?
– ensure a high-level of operational integrity
with less experienced staff?
• IMS Configuration Manager helps
you control, audit, and validate the
parameter definition process
• History record of all changes
• Enterprise view of resources
• Logical search
• Smart editor
• Help

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 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
IMS Configuration ManagerComplements DRD; retainsbenefits of both approaches

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 ?
Skills challenged and resource shortage, not ‘enough’ time
Can be a ‘complex task’, careful planning and implementation needed
“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:
‒ Agenda is customized to a customer’s specific interests and needs

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:
‒ Agenda is customized to a customer’s specific interests and needs

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?
Skills challenges, not ‘enough’ time
Can be a ‘complex task’, thoughtful planning and implementation needed
“Fear factor” – a major change in their approach to managing IMS systems and applications
• Messages delivered:
‒ The HALDB advantage: Provide confidence and motivation to the customer for
moving to the use of HALDB databases
‒ Education on the migration process, provide guidance to the customer on steps to
undertake
‒ 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

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 ?
What means are there for performance measurement, trend analysis, ‘bottleneck’ identification ?
Dynamic IMS buffer pools in V13, how can I take advantage of this ?
‒ 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
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:
‒ Agenda is customized to a customer’s specific interests and needs
‒ Can be combined with DB2 topics as well
