                               Data Protection for SAP on Oracle

               Initial impact: Medium
          Additional keywords: TSM TDP concurrent IO CIO CIOR
    

Local fix

  • Force backint to change the file open flags to
    'O_CIO | O_RDONLY' by exporting the environment variable
    ESD_DBFILE_OPEN_FLAGS=0x00000080
    for the user who performs the backup.
        or
    Remount the database filesystems with concurrent IO option.
        or
    Use RMAN instead of backint.
