List Structure Size

The total size of the structure is dependent on how the structure is defined to the coupling facility. The required size of the coupling facility structure can be determined using the TSSFAR utility. This is done when the systems programmer defines the name of the structure. The amount of data is dependent on how the structure is defined at connection time. The first system to connect to a structure supplies information on how the structure is set up. For example, the number of headers and the maximum data element size, are two of many factors determining the amount of data that can be placed in a structure. These factors are supplied at connection time and are used in a calculation that is done during the connection.
