You may find, when you are debugging a Web service, that the client returns error 0015. This is a time-out, and is caused by the service not returning to the client in the expected time, because you were debugging it. If you find this a problem, you can change the timeout interval by editing the Micro Focus Common Client (MFCC) configuration file, which by default is mf-client.dat, located in %ProgramFiles(x86)%\Micro Focus\Visual COBOL for Visual Studio 2013\bin and \bin64 . You can create your own configuration file of any name or location, but you must identify it using the MFC_CONFIG environment variable.
Open the file and insert:
[defaults] timeout=nn
where nn is the desired timeout period in seconds (at run time the figure is rounded up to a multiple of 5).
