Is the approach of running java batch programs in Liberty profile (supporting JSR352 specification) on z/OS relatively new to the market or been for a long time ?
The reason behind this question is because, am hearing that this is a relatively new attempt by IBM and there are not much of live systems in the market running in this approach. Is that true ?
Note: I understand that the JSR352 has been there for quite sometime but, my question is specific to its support by the Liberty profile in z/OS (mainframe)
Support for JSR-352 showed up in WebSphere Liberty as part of the Java EE7 support delivered in 8.5.5.6 which was back in June of 2015. It is supported on z/OS and all the other platforms supported by Liberty. There are some extra features supported only on z/OS (i.e. SMF recording, a z/OS-specific Command Line Interface).
Support in WebSphere traditional for IBM's proprietary Java Batch product (WebSphere Compute Grid) goes back at least a decade (on z/OS and distributed platforms).
There's a lot of information about Liberty JSR-352 support (especially on z/OS) starting from here: http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP102544
