Tried with them. But since duplicate datasets with same dataset name was created after deletion so it has become little bit difficult to track back the one which was of actual use.
So I was wondering if we have any code which can retrieve the required dataset at once.
Most probably you storage team will take backup of all production files. Contact then and get the tape name where these files are backed up depending on date.
If in case you have authority try running this utility to restore dataset.
//STEP010 EXEC PGM=ADRDSSU
//SYSPRINT DD SYSOUT=*
//IN DD DSN=Tape dataset,DISP=OLD
//SYSIN DD *
