Editor's Notes

  • We start with a compare-and-contrast between online processing and batch processing.
    The point of contrast is the interaction between the request and the processing that takes place. Online processing has, in general, a one-for-one relationship. In addition, there is an expectation of the response being returned in a timely fashion.
    Batch processing on the other hand has, in general, a one-for-many relationship between the request and the result. The request initiates some background processing against a set of data. The result is the completion of the processing against the data. The expectation is that the processing will be completed in some timely but non-immediate fashion.
    ------------------------------------------------------------------------
    What is Batch?
    Batch jobs are are tasks where a user isn’t waiting for an immediate response
    Historically long running jobs that ran on a mainframe that process huge amounts of data
    Large legacy COBOL code base
    No longer the case
    Batch is run on a multitude of platforms using multiple technologies
    Java is extensively being utilized in the batch space
    -------------------------------------------------------------------------
    What is Batch used for?
    Payroll processing, payment processing, claims processing, inventory management, credit card processing, credit risk analysis, report generation, end of day/month/quarter/year processing, etc...
    Read a record from a large datasets, process it, and write out the processed data...continue in a loop.
    Simple…right?
  • There used to be a time when &amp;quot;batch&amp;quot; and &amp;quot;online&amp;quot; processing were quite separate from one another. It used to be the case that online processing was stopped altogether so batch processing would have access to the system resources to complete its work.
    But those days are well behind us. Online processing is becoming more and more a 24 x 7 operation. This is because client access is increasingly global, with people from different time zones seeking access at all times during the day. There may be times during the day when online processing is greatly reduced, but in most cases it is never stopped altogether. That means batch processing much work at the same time as online. To the degree it has dedicated time, that window of time is shrinking.
    The advent of mobile devices means client access is now even more frequent than before. The transaction work that flows back to information processing systems because of mobile device activity is increasing. And mobile device activity may occur at any time of night or day.
    It&amp;apos;s truly a 24 x 7 world for online processing. But batch processing has not gone away. There are still requirements to do batch work. So it&amp;apos;s evident batch and online must be done at the same time ... and in a manner that implies both work cooperatively.
  • Maintaining separate silos of development and infrastructure resources for both batch and online is extremely costly. The uniqueness in development and build technologies requires distinct tools and supporting services, in which there is little if any overlap in skills. There is often a homegrown middleware infrastructure created to try to get some synergies between the two, but this ends up being more of a burden that drives additional maintenance costs.
    The affects of the silos are:
    Increased costs in duplicate development and support staff, duplicate software licenses, and IT hardware.
    With little opportunity for code re-use between the batch and online, there are no efficiencies gained to help in delivering services quickly, and this impacts the ability to deliver services in a timely manner. Furthermore, maintaining a homegrown infrastructure requires companies to dedicate skilled resources to fixing the infrastructure rather than building new business services, also impacting the time to market.
    The distinct technologies for development, automation, etc requires the company to maintain a staff of unique skills for both batch and online, which makes it difficult to be responsive business needs by moving resources between the two disciplines.
  • Integrated Batch and Online
    The picture on this chart represents an objective of cooperative processing of online and batch within same execution runtime -- the managed intermixing of online work with batch work. This is possible when the execution runtime is a multi-threaded design (which IBM WebSphere Application Server is), and the execution runtime is designed to manage the many processes simultaneously (which IBM WebSphere Application Server does). IBM WebSphere Java Batch is a functional solution that is built on top the proven runtime platform of IBM WebSphere Application Server (WAS for short). WAS is today very much capable of handling concurrent online processes simultaneous. To process batch work all WAS needs is an understanding that batch is present, and a container design for handling batch work. With that we&amp;apos;re ready to go into what IBM WebSphere Java Batch is.
    Shared Services and IT Infrastructure
    In addition to the batch window shrinking, there are pressures to contain and reduce costs related to information processing as well. Having separate infrastructures for online and batch ... Separate computers, separate tools, separate support staff ... is an idea that is increasingly being drawn
    into question. Further, custom-built mechanisms for running batch -- particularly Java batch – represent middleware solutions that require a considerable amount of effort to maintain and support. The trend is definitely in the direction of convergence. Online and batch processing are both information processing, and as such can and should be handled in a cooperate, converged manner. This allows for efficiencies in infrastructure, staff, development tooling, and potentially Java assets shared between OLTP and batch. Homegrown middleware solutions are not favored and will eventually be phased out.
    Better Resource and Skills Utilization
    • Skills -- Java skills are simply more plentiful than COBOL skills. That&amp;apos;s a fact. Many
    organizations have very good Java development staffs. It makes sense to leverage those Java staffs for batch work as well.
    • Tooling -- today&amp;apos;s development tooling products are powerful and quite sophisticated.
    Acquiring them also represents an investment in technology and an investment in skills. It makes good sense to leverage that investment across multiple information processing disciplines.
    • Specialty Engines -- COBOL runs on general processors, Java runs on specialty engines.
    Specialty engines (zAAPs) provide a way to lower overall System z costs ... both in acquisition costs as well as ongoing licensing costs. Specialty engines are an attractive solution and leveraging them for batch work is desirable.
    • Cooperative Processing -- online processing runtime infrastructures are very often designed around Java. For example, IBM&amp;apos;s WebSphere Application Server is a powerful Java processing runtime. There is an investment in maintaining that online infrastructure. So to the extent that same investment can be leveraged for batch work as well, the better. The bottom line is that Java for batch processing is very much an area of growing interest, and in fact is in use in many very large processing operations.
    Incremental Adoption
    A primary benefit of WebSphere batch is the ability to introduce Java batch to existing batch processing over time in an incremental fashion.
    Customers have thousands of existing legacy batch applications
    In many cases it would not be feasible to replace significant portions of the existing batch processing at a single time
    WebSphere Batch is designed with key features to facilitate a step-wise approach to Java batch modernization
    Integration with existing processes, applications, operating system services and technologies allows WebSphere batch to be introduced incrementally, while still providing immediate value
  • The WebSphere Application Server product provides what&amp;apos;s known as a &amp;quot;Java EE&amp;quot; (or &amp;quot;Enterprise Edition&amp;quot;) runtime. Java EE is an industry standard specification for an application server that provides a long list of standard application specifications. Part of the design of this &amp;quot;Java EE&amp;quot; runtime is the idea of a &amp;quot;container.&amp;quot; Containers are simply runtime functions that provide managed services to the programs that run in the containers. Container-managed services mean the application programs themselves may focus on their core business logic and not have to implement common functions. WAS by itself has two containers -- Web and EJB. The addition of the WebSphere Java Batch function adds a third -- a batch container.
    Like other containers, the batch container provides function services to the batch applications that run in the container. The chart shows a summary listing of some of those services. The purpose of this presentation is to provide more information about those services. For the purposes of this chart, just scan through the list of services and think about a Java batch program having access to those services. Then think about what it might take if you had to write those services yourself. But of course you don&amp;apos;t have to write them yourself -- they&amp;apos;re provided with the batch container.
    -----------------------------------------------------------------------------------------------------------------
    What about when things go wrong?
    Bad network connection, server crashes, I/O errors…etc
    Or the amount of data is so large you don’t have enough time process it sequentially.
    How do you manage all of your different jobs?
  • We have wrapped all the qualities of service of the Liberty profile around the batch programming model
    Dynamic configuration
    Operational management
    Transactions
    Logging
    High availability
    Scalability
    Tooling
    But why just Liberty Profile? Where’s Full Profile?
    Consistent with the previously announced statement of direction,
    -- IBM intends to certify WebSphere Application Server to Java EE 7 full platform compliance. WebSphere Application Server has made good progress towards this with the WebSphere Application Server Liberty profile features that were made available in WebSphere Liberty Repository through the continuous delivery model. WebSphere Application Server Liberty profile intends to complete Java EE 7 full platform compliance by using this approach.
    -- In addition, it remains the intention of IBM to certify WebSphere Application Server full profile to Java EE 7 full platform compliance.
    -- JSR-352 spec is part of the Java EE 7 Spec. But beyond that, IBM wants to work with customers to understand those “additional” features that provide the best Java Batch experience. Look at Compute Grid, as well as what’s been started in the Liberty Profile beta…
