Refreshing an upgraded vDB from an older dSource

  • 1.  Refreshing an upgraded vDB from an older dSource

    Is it possible to refresh a vDB that has been upgraded to a higher Oracle binary version from a dSource that is still on the older version?

    For example -

    TEST1 is the dSource and is on 11.2.0.1.
    vDBTEST is the vDB that was created @ 11.2.0.1 but has then been upgraded to 11.2.0.3

    Can I refresh vDBTEST from TEST1? Would the binary revert back to 11.2.0.1?

    Thanks!

    Hi Jimmy,
    Currently we do not have a rewind a VDB feature, though there is an open request for this that we are in the process of working on for future versions of Delphix. There are some workarounds to do this, if you haven't made any changes to the VDB the easiest thing would be to provision a new VDB from the point in time from before the upgrade. If you have made changes, a VDB is an Oracle database and you would be able to downgrade just as you would an Oracle database (this Oracle Support article might be helpful); though if you do this you also need to use the process in Upgrading an Oracle dSource so that Delphix picks up the new Oracle binaries. 

    Hope that helps!

    Thanks for the response!

    Not sure if I understand - I do not really mean rewinding a vDB but refreshing from the dSource. Would the upgraded vDB remain the same binary if refreshed from the dSource or would it revert back to the dSource binary?

    If you are refreshing then the VDB will revert back to the dSource binaries since a refresh from the dSource is like reprovisioning

    I do also want to note that you might need to the "upgrade" the VDB again so that it points to the right Oracle binaries
