IMS/DB is a Database Management System
A Database– is a collection of interrelated data items, stored once and organized in a form
for easy retrieval.
A Database Management System – is a collection of programs for storing, organizing, selecting, modifying, and
extracting data from a database.
IMS DB is organized hierarchically– To optimize storage and retrieval – To ensure integrity and recovery A

IMS HALDB Highlights
Database types– PHDAM - partitioned HDAM– PHIDAM - partitioned HIDAM
• Index is also partitioned– PSINDEX - partitioned secondary index
Hierarchic structure is maintained– A database record resides in one partition
Partition selection– By key range or by user exit routine
...
© 2011 IBM Corporation
HALDB - What Is It?
Large Databases– Databases are partitioned
• Up to 1001 partitions per database• Partitions have up to 10 data set groups• Partition definition separated from database structure definition
High Availability Databases– Partition Independence
• Allocation, authorization, reorganization and recovery by partition– Self-Healing pointers
• Reorganization of partition does not require changes to indexes or logically related databases which point to the partition
Partitioned Database Data Sets– PSINDEX
• 1 data set - secondary index data set– PHDAM
• 2 minimum/11 maximum - 1 for data, 1 for indirect list data set– PHIDAM
• 3 minimum/ 12 maximum - 1 for data, 1 for indirect data set, 1 for primary index data set
© 2011 IBM Corporation
IMS HALDB Partitioning Options
Two methods of partitioning– Key range
• Each partition is assigned a range of root segment keys
– Partition Selection Exit routine• The exit routine assigns a root segment to a partition based on its key
0 - 1000 1001 - 2000 2001 - 3000 9001 - 9999...

Comparison of programming approaches for accessing IMS:
Innovative ImprovedUsability
OpenStandards
Scenario
Accessing IMS data through TCP/IP from a non-Java application that resides on a distributed non-z/OS platform or a z/OS platform that is on a different LPAR from the IMS subsystem.
Accessing IMS data through TCP/IP from a Java application (non-J2EE) that resides on a distributed non-z/OS platform or a z/OS platform that is on a different LPAR from the IMS subsystem.
Accessing IMS data through TCP/IP from a J2EE application that resides on a distributed non-z/OS platform or a z/OS platform that is on a different LPAR from the IMS subsystem.
Approach
Use your language of choice to issue DRDADDM commands
Use the type-4 JDBC driver or the DL/I for JavaAPI
Use the JCA 1.5-compliant IMS distributedDB resource adapter
© 2011 IBM Corporation
Solution highlights – IMS Connect and ODBM
IMS Connect– TCP/IP endpoint for type 4 connectivity– Authentication engine for type 4 connectivity– Focal point for two phase commit for type 4 connectivity– Proxies one phase commit requests to ODBM
Open Database Manager (ODBM)– Processes type 4 database requests– Processes type 4 one phase commit requests– Authorization engine (via ODBA) for database access– Processes type 2 database requests when using ODBM compatibility for ODBA
• Compatibility mode will allow ODBA to proxy requests to an ODBM address space on the same LPAR

IMS Enterprise Suite 1.1 – Business Value Provided
Solution Statement– IMS Enterprise Suite is a single product offering that provides
• Consistent installation and service process for select IMS SOA offerings,• Means for isolating offerings that contain open source.
Business Value– Part of IMS simplification strategy – simplifies installation and maintenance of select
IMS SOA offerings – First step in helping customers improve their development productivity by shifting
focus from maintenance to application development.
Challenge Addressed– Several components require open source code which customers have to personally
obtain and keep isolated from their IMS systems and other high value, business critical systems
© 2011 IBM Corporation
Graphical User Interface (GUI)
– Leverage Eclipse, Eclipse Modeling Framework (EMF) and Graphical Editor Framework (GEF)
– Can be installed as a stand-alone function or on top of other Eclipse based products (i.e. RAD 7.5, RDz 7.5, Data Studio) using IBM Installation Manager
IMS Database Visualization Tool
– User can visualize an entire IMS PSB and DBD in a multi-page graphical editor.• Each PCB can be viewed, saved and printed individually. Each PCB editor shows
the IMS DB hierarchy with the segments, fields, field types, etc.– User can also search an entire IMS PSB for a specific PCB, segment, or field.

IMS Value
IMS is Efficient: 22K trans/sec on a single eight way z9. Remarkable performance that translates to the most cost efficient run-time environment. Reusing IMS transactions and data saves money.
IMS enables Growth: IMS SOA provides Open, standard interfaces allowing ‘any-to-any’ connectivity and access for new applications.
IMS supports Growth: with IMS scalability you can just keep on growing. Customers have routinely handled peaks of 100 million transactions in a day.
IMS is Resilient: Customers report going thousands of days without an unplanned outage. One bank reports availability of 99.998% over 10 years, 1.5 hours for planned outages.
IMS and z/OS are secure
Most efficient run-time, maintains application investment protection
Fully integrated into today’s AD toolsets
Fully integrates with WebSphere Application Server/ ESB / Process Server
Fully supports SOA
Improved efficiency and reduced skill requirements for systems and development staff
Flexibility: JAVA, COBOL, C, PL/I, XML, Web 2.0…
Continuous improvement to Rock solid availability

The Message
IMS continues to be a premier server with architected standard interfaces– New products and tools from a variety of vendors provide access to IMS transactions
and data
SOA is revolutionizing the way businesses are being designed and run. For it to make sense:
– All assets must be easily accessible in a standard way– All data must be represented and manipulated in a standard way
Our goal is to leverage IMS Database Manager as an integral part of the enterprise in the evolving business world through
– Addition of support for complimentary standards surrounding IMS data connectivity, data representation, and application development
And to allow you to realize the promises of building a Service Oriented Architecture:– Simplify the business environment– Respond to market changes more quickly and cheaply

Grow your IMS Business and Protect Investment
How to add new or expand existing IMS applications and IMS data?– Target LOB applications architects & management
•Today awareness of “SOA-ing” IMS applications with this audience is nil– Publicize success stories internally
Back to IMS and z/OS basics messages– Superior performance, bulletproof reliability– Don’t risk your business by moving off IMS– Value proposition:
•Growing transaction workload grows your revenue!•More gateway on the LOB business logic and business data•Drive demand for new function, justify V to V upgrades
