Control File Externals

This section discusses the two fundamental, high-level architectures of cross-system communication used by CA MIM. The two primary types of CA MIM control file architectures are referred to as the physical architecture and the virtual architecture. While the internal structures of physical and virtual control files are exactly the same, differences do exist as to how CA MIM Driver serializes access and performs I/O operation with each type of control file. This section takes a look at the differences between the CA MIM physical and virtual control file architectures.
