    Using XD storage server newer and older version on db node

    933988

      Dear Team,

      My customer is using the XD H/R and going to upgrade from 11.2.3.2.1 to 11.2.3.3.0.

      but only 2 nodes of total 4 db nodes will be upgraded to 11.2.3.3.0.

      (for later, the others are upgraeded.)

      then, is it possible to use mixing different version on db node without any problems?

      thanks in advaned.

      Regards,

      Hoony

          Hi Hoony,

          If you dig into an exacheck output you will find the following check.

          Kernel version comparison across cluster

          It mentions the following risk.

          Potential cluster instability due to kernel version mismatch on cluster nodes.

          It is possible that if the kernel versions do not match that some incompatibility

          could exist which would make diagnosing problems difficult or bugs fixed in the

          later kernel still being present on some nodes but not on others.

          It is a best practice to complete the patching in one go.

          Regards,
