    System error: Java heap space

    Bob Janson

      Hi all,


      When trying to create an output from my Tableau Prep Flow (2019.2) I get an error "Java heap space".


      When looking at the other people who experienced this error before it seems like I have to increase something in Java with the following code:


      tabadmin set wgserver.vmopts "'-Xmx1024m -Xss2048k -XX:MaxPermSize=128m'"

      tabadmin configure

      tabadmin restart


      According to: https://kb.tableau.com/articles/issue/error-javalang-outofmemoryerror-java-heap-space-and-application-server-is-down


      However I don't know where to insert that code, just putting it into Command Prompt gets you nowhere...


      Best Regards,


      Bob Janson

          That solution is for Tableau Server (and an old version of Tableau Server at that).  tabadmin is a set of command line utilities to control how Tableau Server works.


          There's no comparable thing to enter for Prep.  I'd open a support case with Tableau on this one.

          Are you on the latest release of 2019.2 (2019.2.3, I believe)?
