DFSMSrmm Web service is optional and provides support for these tasks:

• Enables the high-level language application programming interface to be used from any system or platform that can run Java, C++, or any language that supports the Web services standards.
• A single call to the application programming interface to run a subcommand and receive all the output.

The infrastructure to support the use of Web services must be implemented and available on both the application system and the target z/OS system running DFSMSrmm. See Setting up DFSMSrmm web service for information about setting up DFSMSrmm Web service.
