Hello team, good day!
I need to install WebSphere Application Server Liberty for z/OS and I am looking for some information about this product (product id, fmid, etc) but it is very hard to get this kind of information on IBM site. Sometime I get some pages and it appears that it is embedded with WebSphere Application Server product but sometime it appears to be a standalone distributed product. I am a little confused.
Could someone help me to clarify, please?
Thank you and regards!
Good morning! WebSphere Liberty is included (and only available as part of) the WebSphere Application Server for z/OS license. But they are installed separately.You have several install options: - Download a current compressed copy of Liberty from IBM Fix Central and uncompress it on your z/OS system with pax. THis is called a portable install. - Order an IBM ServerPac containing a portable install, as a z/OSMF portable software instance. - Order an IBM ServerPac or CBPDO which contains sample install jobs and repositories; you do the Installation Manager install. - Install yourself with IBM Installation Manager from downloaded repositories or from the Web. You can download the (fully commented) install jobs from ibm.com.All of these require entitlement. BUT for non-production use, you can also run Liberty directly from the copy included in all supported levels of z/OS at /usr/lpp/liberty_zos.
Please let me know if you have any questions!Jeff Mierzejewski(I'm the WebSphere install and configuration architect for z/OS)
Hi Jeff Mierzejewski,
Good morning! Than you for your answer I really appreciate it.
I found the product embedded with z/OS as you've mentioned in your answer and it help a lot. Now I have a doubt regarding the license, because the customer needs to implement a new solution: Is the product distributed with z/OS licensed or is it a permission to use it? Should be ordered a specific license to get future support from IBM?
Yes, for support (and downloads) you need entitlement to WebSphere Application Server for z/OS Version 8.5 or Version 9.0 (possibly Family Edition or others? not sure).
Hi Jeff, good morning.
It is clear now. Thank you for your clarification!
There's a discussion of Liberty Embedded in z/OS, Liberty in CICS, Liberty in other products (like z/OS Connect), Open Liberty and Liberty as part of WebSphere Application Server for z/OS (whew), here:https://community.ibm.com/community/user/wasdevops/blogs/david-follis/2021/04/14/can-i-run-open-liberty-on-zos?CommunityKey=2878fdb3-1d66-40b6-b9ed-0cfff8979b7d
We are licensed for tWAS z/OS, but I'm curious -- how does the Liberty installed with the z/OS Server Pack at /usr/lpp/liberty_zos for into the equation? Can it be used instead of the tWAS z/OS-bundles version?

The copy that comes with z/OS is intended for use by IBM products (like z/OSMF), but is available for "non-production purposes" (see your z/OS license agreement for a paragraph defining that...). And anyway since you're paying for WAS z/OS (which includes both traditional and Liberty) you'd want to use the one you're paying for so you can get fixes for it. The embedded copy only gets updated (usually) twice a year with some PTFs for security-integrity issues. If you were using the embedded copy (for non-production purposes) and hit a problem you can't get support or even install an existing fix if you found it yourself.
I throw this link in here again where I tried to explain all the different flavors of Liberty floating around.https://community.ibm.com/community/user/wasdevops/blogs/david-follis/2021/04/14/can-i-run-open-liberty-on-zos?CommunityKey=2878fdb3-1d66-40b6-b9ed-0cfff8979b7d
The embedded copy registers with z/OS differently than the product copy so it shows up separately in your SCRT reports. This will be different than when it is used by IBM products like z/OSMF when it should show up as that product and not Liberty. The net being that if you use the embedded copy for non-production purposes it will show up in SCRT. In case you were wondering...
We are licensed for tWAS z/OS, but I'm curious, how does the Liberty installed with the z/OS Server Pack at /ust/lpp/liberty_zos fit into the equation? Can it be used without separately installing the tWAS z/OS bundled Liberty?
