WebSphere Application Server Liberty for z/OS

  • 1.  WebSphere Application Server Liberty for z/OS

    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!

    Alex

    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!

    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?

    Regards,

    Alex

    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).

    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:

    Hi all,

    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?

    Thank you!

    Bob

    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...

    Hi all,

    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? 

    Thanks!
