Error description

• Rational Developer for System z Data Editor feature 'Find and
  Replace All' will fail with large datasets
  
  When using the z Data editor to change a column in a large file,
  the output file is corrupted: it contains more lines than
  expected and the added lines are copied from the original file.
  
  Example create a TEST dataset with 30000 records
  Note a dataset with 10000 records does not fail

  - edit TEST dataset using the z Data Editor
  - position the cursor before 0 on the first line
    (just before 'File'),
    right-click and select Find/Replace (Ctrl+f)
  - in the Find/Replace dialog set options to
    Find:         0

  01.When the RDz server and client saved a large data set,
     updated records were sent to the server and then the server
     merged the updates and the data set content. But the server
     failed to merge the content when the updated data size was
     large.
  

Problem conclusion

• 01.The RDz server and client were fixed to merge large updated
     records and the original data set properly.
  

Temporary fix
