MFBSI can be used on all the platforms supported by Enterprise Server/Enterprise Developer. For a list of the supported operating systems, check the Product Availability section on the Micro Focus SupportLine Web site: http://supportline.microfocus.com/prodavail.aspx.
As long as a shared folder can be defined, the scheduler can submit MFBSIJCL on one platform for execution of a JCL in MSS to another platform.
