What if the source is upgraded?

  • 1.  What if the source is upgraded?

    Hi,
    suppose I've created a dSource that links a source server running os version 1.x and db version 1.x and from that dSource I've provisioned a couple of vDB, on target hosts of course also 1.x; in other words my target servers host both rights operating systems and db binaries, the same as the real source server.

    Suppose now that I've upgraded my original production source to os version 2.x and db version 2.x, the link with dSource will pull new data from source...
    ...but my target environments are still running os and db of the old version. This could avoid the instance functionalities.

    Is there a way to have all aligned at the same versions?

    Thanks

    Hello,

    There are documented procedures for upgrading all different databases. For example, here is the procedure for upgrading on Oracle dSource:

    https://docs.delphix.com/display/DOCS50/Upgrading+dSources+after+an+Oracle+Upgrade

    And the procedure for upgrading an Oracle VDB:

    https://docs.delphix.com/display/DOCS50/Upgrading+an+Oracle+VDB

    I hope this helps answer your question.

    Thanks,
      Neal

    Hi Giacomo, In General before upgrade your production you want to validate the patch procedure and possible regression it would introduce and you do it first with a non-production env. (so not dsource). But, in your case you have 2 choices: 1 - Go ahead and upgrade the VDB as per the answer of Neal 2 - Create a new VDB that will be an upgraded one and let the old vdb just as archival one and use it with the oldest version (never refresh it) you have to disable automatic polling of log/archives and refresh ones Regards, Mouhssine
