You should have everything you need, but I’ll add some “footnotes”: * IBM has released Version 21 of the IBM Semeru Runtime Certified Edition for z/OS, available to z/OS licensees at no additional charge. Versions 11 and 8 you really shouldn't bother with at this point since they'll reach End of Support in 2025 and 2026 respectively.
* You have CICS Transaction Server, and CICS supports Java programs quite nicely. Including with the CICS Liberty runtime if you'd like JEE support. All no additional charge. * There are multiple ways for Java programs to interact with Db2, but the most popular is still the JDBC driver, also available at no additional charge. Details available here (Db2 Version 13 documentation link): https://www.ibm.com/docs/en/db2-for-zos/13?topic=java-supported-drivers-jdbc-sqlj * How'd you like to manage the Java source code and other program artifacts, ideally together with your COBOL source code? The popular answer is based on Git. IBM offers an optional (but really nice) tool called Dependency Based Build (DBB) that supports COBOL, Java, and other programming languages managed in Git-based repositories. Regardless, it's a good idea to give some thought to how programs get deployed to z/OS, ideally in a DevOps-oriented way. Developers shouldn't have to do something special or awkward to deploy to z/OS, and fortunately they don't have to. * IBM watsonx Code Assistant for Z, another tool, can even do most of the heavy lifting to convert COBOL to (well-structured) Java (not to "JOBOL"). * If you simply want to shift VSAM-based data to Db2 without changing programs (or at least without requiring application changes at any specific pace or deadline) then IBM CICS VSAM Transparency can get that job done. * If your developers prefer containerized Java applications then that's straightforwardly possible on z/OS, too — via the IBM z/OS Container Platform as a notable example. ————— Timothy Sipples Senior Architect Digital Assets, Industry Solutions, and Cybersecurity IBM Z/LinuxONE, Asia-Pacific [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
