CHA
The CHA (Common Hierarchical Area) provides context functionality in a distributed server environment. This enables UNICOM® Digital Transformation Toolkit (UDTT™) applications to have distributed runtime repositories so that they can share information with other applications. Non-toolkit applications can use the CHA as way of holding general global session information.
