Focus development skillset around Java
 As Java skills become more prevalent and fewer “classic compiled language” (eg. COBOL, PL/I, etc.),
the motivation is to focus development effort around a common programming skill.

 Java processing can be offloaded to the zIIP, lowering the overall cost profile of running batch
processing on the mainframe. In a word: cost.
•
Give yourself maximum platform flexibility
 Things change. Sometimes the reason for choosing a platform change; using Java gives you the best
flexibility to take advantage of the right platform at the right time for your application.
Important: this does not mean wholesale replacement of existing function that
serves the business needs. Business imperatives drive technical solutions.

Developer concerns about Java on z/OS?
Cliquez et modifiez le titre
Can Java really run on the mainframe?
• Yes! Java has been running on the mainframe for over 15 years, and it runs well! Excellent performance today. Check it out!
• Java runs in the z/OS Unix System Services (USS) mode. z/OS has had a Posix certified environment for over 20 years.
• Java is java is java. If your application is “pure” Java, it will run on z/OS unchanged. 99% of the migration issues that come up are because (a) the
developer did things that aren’t “clean” (eg. Hardcode “c:\myBackSlashDir\log.txt”) or uses native (JNI) interfaces, which should always be identified and
isolated.
Do I need special APIs for z/OS?
• Probably not, but it depends what you’re doing and what Java environment and “framework” you’re using. This is where intelligent choices matter.
IBM does supply a JZOS class library with some specific routines that you might want to use (eg. Sending a message to the z/OS console, reading z/OSspecific file structures, etc.).
Do I need to use one of those funny “green screens”?
• No, not any longer. IBM provides z/OS Explorer free of charge, an Eclipse-based interface for viewing, editing, submitting and general interfacing with
z/OS today
– Quatrième niveau
• Better yet, you can also use IBM’s Rational Application Developer for z.
Cinquième niveau
Do I need to do everything in EBCDIC »for Java
on z/OS?
• No! You can quite easily work in ASCII or Unicode which are supported. Of course, if you interface to some z/OS –specific environments (eg. CICS, IMS,
z/OS datasets, DB2…) than you will most likely need to translate to EBCDIC, but this would likely be the case if the Java was running outside of z/OS also.
It is a price you pay for interfacing with mainframe assets.
How about debugging Java code on the mainframe?
• You can run the same traces that you run on distributed platforms, and get the same diagnostics. Interactive debuggers can also be used, such as IBM’s
Rational Application Developer.
• For tuning, IBM Support Assistant (ISA) works with a z/OS JVM just like on distributed platforms, as well as Jinsight-live, a lovely visual performance
analyser. All available free of charge.
How do I control the Java? Start/Stop programs, etc?
• You can use the Unix environment on z/OS just like distributed, but you’ll probably want to work with the z/OS team to get some assistance to
automate things (eg. Set up jobs). This is where the partnership is important. Or you might want to use a richer, full-function Java runtime environment
on z/OS….
