Error description

• Db2adutl Extract will show errors which might point to a corrupt
  image, when actually the image is perfectly valid.
  
  Example:
   db2adutl extract db TEST taken at 20150929060717
  
  Query for database TEST
  
  
  Retrieving FULL DATABASE BACKUP information.  Please wait.
  
  
  
     FULL DATABASE BACKUP image:
  
        ./TEST.0.itest.DBPART002.20150929060717.001, DB Partition
  Number: 2
  
        ./TEST.0.itest.DBPART002.20150929060717.002, DB Partition
  Number: 2
  
        ./TEST.0.itest.DBPART002.20150929060717.003, DB Partition
  Number: 2

  Error unexpected data seen at the end of the sequence, image
  maybe corrupt.
  
        ./TEST.0.itest.DBPART002.20150929060717.003
  
        Warning: backup object already exists.
  
  Overwrite? (Y/N) Y
  
           Writing to file:
  
              ./TEST.0.itest.DBPART002.20150929060717.003
  
  Error unexpected data seen at the end of the sequence, image
  maybe corrupt.
  
  
  The images that have got failures are 4k in size:
  
  -rw-r-----    1 itest db2tadm  295804928 Nov 05 16:49
  TEST.0.itest.DBPART002.20150929060717.001
  -rw-r-----    1 itest db2tadm       4096 Nov 05 16:49
  TEST.0.itest.DBPART002.20150929060717.002
  -rw-r-----    1 itest db2tadm       4096 Nov 05 16:49
  TEST.0.itest.DBPART002.20150929060717.003
  
  The reason for this size is that when backing up a  database
  with multiple sessions, some sessions are "hard" workers  and
  back up majority of data, some sessions are "lazy" workers and
  might not have a chance to back up any data.  For each backup
  image, 4K in space will be reserved for the media header. These
  are valid images.
  

Local fix

• Run db2adutl verify and confirm the images are fine.
  Add up the size of the image files in bytes. This should match
  with the size
  of the backup reported in the db2diag.log "MESSAGE : Actual size
  of backup in bytes:"
