Performance is based on measurements and projections using standard IBM benchmarks in
a controlled environment. The actual throughput or performance that any user will
experience will vary depending upon many factors, including considerations such as the
amount of multiprogramming in the user’s job stream, the I/O configuration, the storage
configuration, and the workload processed. Therefore, no assurance can be given that an
individual user will achieve results similar to those stated here.

3. Online and batch processing differ primarily in the type of interaction and
expectations for responsiveness
Request
Response
Request
Response
In general:

Interaction is one-for-one ... that is,
request with matching response

Expectation is for response to follow
request in a near-immediate time frame

Examples: Inventory query, Website
shopping transaction, eBanking account
withdrawal
Online Processing
Submit
Complete
Start
End
Process
In general:

Interaction is one-for-many... that is, initial
request results in many results from
processing

Expectation is for results to finish within some
determined non-immediate time frame

Examples: Month end tax calculation, Period
end statements and reports, Data

WebSphere batch capabilities are fully integrated in WebSphere
Application Server (WAS) as of v8.5. For installations prior to WAS
v8.5, the WebSphere Compute Grid product is required.

8. JSR-352 and Java Batch
• JSR-352 Specification started in 2011 by IBM as spec lead
• Based on programming models and experience from Compute
Grid, z/OS Batch, and Spring Batch.
• Specification developed through the JCP process by industry
leaders in the batch space.
• Approved by expert group and accepted as part of Java EE 7
• Finally, a standard for the batch programming model!

9. The Java Batch Programming Model
• Batchlets and Chunks
• Unmanaged and managed batch step processing
• Ability to stop, restart, checkpoint a job
• Listeners
• Provide hook points into various lifecycle events of a job
• Splits and Partitions
• Allow work to be parallelized
• Restart, skip, and retry capabilities
• Allow for increased resiliency of a long running batch job
• Job Specification Language
• XML based job definition with built in dependency injection

Why Java Batch and Liberty?
We have wrapped all the Qualities of Service of Liberty Profile
around the Java Batch programming model.

11. Java Batch and the Value it Provides

Java main()
Java Java
Traditional Batch
Processing
Early Java Batch
Processing
Standardized Java
Batch Processing
The essential business value of batch processing is the
same; the methods and tools change and bring added value:
Java for Batch Processing
•Availability of programming skills
•Offload of Java to z Systems
specialty engines
•Leverage modern development
tooling
•Priority schedule both online and
batch transactions
JSR 352 Java Batch
•All the benefits of Java Batch (left)
•Standardized programming interface
•Standardized = greater skill availability
•Platform / vendor neutrality

12. WebSphere JSR-352 Java Batch Qualities of Service
• REST API
• Java Batch in the Liberty profile
provides an easy to use rest interface
to remotely manage your batch jobs
• Ability to start, stop, restart, view job
instance and execution data, and
access job logs
• Job Logging
• Server logs are interleaved with
application records for easy
debugging
• External scheduler integration
• Provides the ability to combine
enterprise quality scheduling with
batch

13. More about tooling
• WebSphere Developer Tools
• Create Java Batch Applications using the JSR-352 programming
model and XML job definitions
• Job Creation Wizards
• JSL Editor
• Java class wizards
• Simple to submit, test, and debug applications
• Remote deployment and debug capabilities
• Simple graphical UI to monitor jobs

14. Partnership with SICOOB
• SICOOB has made extensive use of the Java Batch / JSR-352
support available in the Liberty profile beta:
https://developer.ibm.com/wasdev/downloads/liberty-profile-beta/
• They worked closely with onsite IBM team and through direct
communication with the development lab to migrate from their
existing homegrown batch framework to Liberty Batch.
• We are continuing to work together to scale their batch
environment.
• SICOOB provided excellent feedback during the migration
process:
•Liberty is released in a much more agile delivery cycle allowing IBM to
respond quickly to any feedback
•SICOOB was able to pick up our latest runtime and tooling updates as
they were released to decrease their end-to-end development time

28. COBOL in the world
“…COBOL skills are highly entrenched in the baby boomer generation”
(by Dale Vecchio – Gartner Research VP)

29. COBOL in the world
In 2007, Cobol topped the list of dying computer
skills of ComputerWorld magazine;
Difficult to find skilled developer;
Y Generation considers COBOL archaic, being
only attracted by elevated salaries;
Not just knows COBOL, other news skills are
necessary, as EBCDIC, VSAM, ADABAS.;

34. Sicoob Challenge
• Worldwide reference lack in processing core banking business
in Java*;
• Late standardization, only proprietary Frameworks;
• Batch Modernization:
• Bring batch concepts to JAVA;
• Batch as service;
• Batch execution environment:
• Dynamic online transaction and batch runtime;
• Share business logic;
• Parallel processing of batch jobs;
• Enterprise scheduler integration (Job dispatching);

35. Sicoob Java Batch Framework
• In 2012, Sicoob developed his homegrown Java Batch
Framework;

36. Flow
• Logical grouping of all jobs to be
scheduled and executed;
• No code is necessary, it will be used
only in design time;
• Cron expression;

41. Why Sicoob has
decided to migrate to
JSR352 and WAS
Liberty Profile?

42. Sicoob Motivations
• Final release of JSR352 was approved in 2013.
• In few years will be more expensive to maintain and train
developer in our framework;
• Sicoob’s presented challenges were technically overcome
• IBM Development Tools and IBM Support;
• Effort to migrate AS instances to WAS

53. Points of our development process
• Understand the difference between our framework and JSR352
to transcribe our code as chunk or batchlet;
• When batchlet, identify itemReader, itemProcessor and
itemWriter;
• This is the greatest effort of our work;
• A good business logic layer makes the migration easier;
• Abstract flow’s orchestration;
• Transfer the transaction controller to batch container;

analysis of batch routines;
• Documentation for batch is quite satisfactory
• IBM Knowledge Center
• WASDev blog
• GitHub JSR352 Repository
