JCL - DDName - File Allocation

Hi All,
Please find the scenario and share your suggestions.
Scenario:
3 jobs has to run in parallel. 3 different jobs : 3 different input files, but same layout – Same kind of Processing . Same program is getting executed. (Program has only one DDName).
In Test region:
In Test region 3 jobs are running in parallel, successfully with one DDName - creating 3 output files (GDG versions) each for one Input file, successfully as expected.
Question is:
With One DDName - 3 different input files – but 3 different jobs.. how in the run time in production both are associated.. Is it will run fine..? or may give some allocation error..? (Please Note: In Test region it is running fine.). Please share your thoughts on this.
