Enterprise Server provides the execution environment for applications created with any IDE variant of Enterprise Developer. It is available in two variants: a standard product where both 32-bit and 64-bit sources can be executed, and a 64-bit-only product that is designed for pure 64-bit environments (that is, it has no 32-bit dependencies).
Enterprise Server supports IBM® MVS®, IBM® COBOL, IBM® Enterprise PL/I for z/OS®, IBM® Assembler, IBM® CICS®, IBM® IMS®, IBM® JCL, IBM® DB2®, IBM® z/OS®, IBM® OS/390®, IBM® WebSphere MQ®, and IBM® zEnterprise® file formats and common batch utilities, including SORT. This means that you can develop and maintain the core mainframe online and batch applications under Enterprise Developer. You can then deploy these applications back on the mainframe or migrate them onto one of the Micro Focus Linux, UNIX or Windows-based production platforms running on Enterprise Server.
