  • 1.  Changing USER_DIR after installation

    Posted 01/19/24 01:32 PM

    Hello,

    We have had z/OSMF setup in our sandbox environment for quite a while now. When it was first implemented, it was done using the default values and the USER_DIR being used is /global/zosmf. However, we would like to change the directory to conform to our standards.

    I would like to understand if this is possible and if there are any considerations we need to take.

    Is it just a matter of copying the existing contents of /global/zosmf into /opt/zosmf and update PARMLIB member IZUPRM00 and PROC IZUSVR1?

    Would doing this impact any work and settings that has been done in z/OMSF?

    Cindy, you are correct, to move your z/OSMF data directory it is a simple matter of copying the existing directory content to your new desired location, then updating that directory value in your PARMLIB member and the IZUSVR1 proc.  Changing the directory should have no impact to any existing z/OSMF work or settings.

    Hello Cindy, 

    We went through a similar change, however, we went from USER_DIR=/var/zosmf / to /global/zosmf/ I seem to recall that we experienced problems with accessing existing workflows after the update to USER_DIR=/global/zosmf which would result in messages similar to the one below..

    Workflow definition file "/SYSTEM/var/zosmf/data/app/IZUWorkflows-97276581-4f9e-498e-9453-8ddf85baf2aa/datasetFiles/INST@.INSTALL@.SERVRPAC.WORKFLOW(VERIFY)" was either not found or cannot be accessed.

    To resolve this we had to update several workflow definition files to reflect the change from /var/zosmf/... to /global/zosmf/...

    Hi Nicholas,

    Thank you for sharing your experience. I believe workflows let you choose where to save the workflow definition file which can be a unix location or a z/OS dataset.  Did you notice this behavior also for workflows whose definition file is stored in datasets?

    Thank you,

    Cindy Diaz

    Hi Cindy,

    Sorry I re-read your question and I don't believe that we have any workflow definition files in datasets just in our USS location

    Hello Cindy,

    Benefit of using /global is that /global is sysplex wide mount point. If you have a "Shared file system" for z/OSMF data directory under /global, you can start a z/OSMF instance on any system in a sysplex (assuming host name for z/OSMF is DVIPA enabled).

    If you decide to move z/OSMF data directory from /global/zosmf, I suggest you first look at IZUMKFS sample in SYS1.SAMPLIB and setup new directoy as described in this sample before you copy data from /global/zosmf

    Hi Hiren,

    The one we are planning to use is also sysplex wide. Are there any other benefits to using /global/zomsf, for example for applying maintenance or some other scenario?

    Also regarding Nicholas experience: if our workflow definition files are stored in datasets, is it safe to assume we won't run into issues accessing workflows?

    Thank you in advance,

    Cindy Diaz

    What about changing the HOME directory for user=IZUSVR?
