I have

Server#1 having RM/Cobol Compiler + XML Extension :

> Able to compile Cobol Program with XML.  

> Execute Cobol Program and read xml.

Server#2 has RM/COBOL Compiler + XML Extension. 

> Able to compile Cobol Program with XML. 

>Not able to Execute Cobol Program failing for "object files not licensed for XML Extensions"

Sorry I am not too much in infra. Do I need to reinstalled RM/COBOL Compiler and XML Extension or Reintalling XML Extension will fix issue.

The most straightforward solution is to reinstall XML Extensions on server 2.  

You may very carefully look at the license.vlt file, to see if XML Extensions is in the vault.  Do NOT modify license.vlt.

The XML Extensions license affects the compiler object file output.  This is why you can compile the module, but get the error message when you attempt to execute the program.
