File extension hcr information

file extension HCRis also known as IBM HCD/HCM Production configuration. HCM and HCD are support/ base elements introduced to make creation and management of I/O configuration definitions easier. The user can freely use them as configuring tools and not incur additional costs. This is a new type of support that provides an easy-to-use but comprehensive environment that is similar to the one available with z/OS. HCD allows the user to define logical I/O configurations for the OS and channel subsystem. HCM that is PC-based extends configuration management scope to tracking physical configuration such as named cables, patchports and cabinets.
All HCM operations start with diagram configuration provided by HCM to display connections between objects that have logical configuration in their relationship with physical configuration. HCD and HCM are a pair and work together to simplify the process of creating and managing software and hardware definitions of the users I/O configuration. HCD helps in creating and maintaining IODFs. Work IODFs serve the purpose of configuring changes, while production IODF’s define the user’s production systems. Production IODFs, which are generated from work IODF, are used during IPL time, a fact that cannot be changed.
