    rollback 11.2.0.3.8 GI & DB patch then watch-out

    fru92thu

      Today I  tried to patched my RAC One Node (2 node) cluster to 11.2.0.3.8. I was on 11.2.0.3.6 prior to this.

       

      I started by only patching Grid Infrastructure & DB home on node 2.  The GI patch was successful but the DB patch had 1 failure so I decided to rollback the DB patch - this also rolled back my GI patch.

       

      Everything was back to 11.2.0.3.6 and when I tried to restart my acfs resource on node 2 it failed to start with an ACFS/ADVM kernel not supported error. The acfs resource was working on node 1 which has exactly the same kernel version!!!!

       

      After loads of searching I found out that although Oracle had rolled back the patch, it didn't update or use the correct osds_acfslib.pm (located in $GRID_HOME/lib). This file that Oracle either replaced with a vanilla copy of modified didn't have a section in it for

      my kernel version - 2.6.32-400

       

      I therefore copied the fresh copy of this file from node 1 to node 2 and then ran

       

      acfsload start -s

       

      lsmod | grep oracle

       

      --- this then showed

       

      oracleacfs

      oracleadvm

      oracleoks

       

      crsctl start res <acfs resource name> -n <node name>

       

      ACFS started fine after this! Hope it helps someone...
