Thanks Tim, this is good information. I appreciate your contributions to the community. I have to say that Liberty might be the most confusing product offering from IBM *ever* in terms of what versions and license options are available.
A) For instance, there is this: https://developer.ibm.com/wasdev/docs/websphere-application-server-everyone/ This seems to be different from the "Open Liberty" version that you mention. Is it available for z/OS? It appears to be a subset, since in the article it says: "You can see the list in the knowledge center <http://www.ibm.com/support/knowledgecenter/SSEQTP_8.5.5/com.ibm.websphere.wlp.doc/ae/rwlp_feat.html?cp=SSEQTP_8.5.5%2F1-0-2-2-0> (this license’s features are in the same column as *WAS express*)." *If you follow this knowledge center link, there isn't actually a column for WAS express!* B) If you go to: https://developer.ibm.com/wasdev/ and download Liberty, you seems to get a pure-java implementation. The README doesn't mention z/OS, and I don't see any Platform-specific JNI libraries, or zos*.jar files. So, I assume that basic stuff like SAF/RACF authentication won't be there. C) The basic IBM Liberty z/OS questions are these: - Which versions are available (independently or embedded in something else) for z/OS? - Which versions allow applications that are not signed by IBM? - What features are included or excluded from each? - What licenses are available for these versions? - How do you obtain these for z/OS?
