Hi Vivek,

Datafiles are marked MISSING when they are offline/read-only. Do you have 
datafiles in offline/read-only state in your production database?

You can identify which MISSING file is associated with which actual data file. 
MISSINGnnnn is the normal file naming convention, where "nnnn" is the file 
number in decimal.

After creating the controlfile, you may rename all MISSING files with their 
respective datafile's instead of dropping them.

  For a Test Database the Controlfile needs to be CREATED from an existing 
?backup control file to Trace SQL Script? but a few Datafiles are MISSING.
  How is the Controlfile to be created in such a case?
  I am assuming the following Steps:-
  1)Missing datafile names should NOT be Removed from the Controlfile Trace SQL 
  2)Control file should be created.
  3)Thereafter Missing datafiles should be Dropped.
  Cheers & Thanks
