RACF sysplex communication

RACF® sysplex communication requires the use of an installation-defined data set name table.

All RACF members of the data sharing group must use compatible data set name tables. RACF enforces use of the same data sets when RACF is enabled for sysplex communication. It is recommended that systems sharing the same RACF database ensure their use of a compatible data set name table by accessing ICHRDSNT from a common library.
The number of resident data blocks specified for buffers can differ between systems in the data sharing group.

Note: When RACF is enabled for sysplex communication, the data set names and the statistics and backup flags are defined by the first system to be assigned to the data sharing group. Any subsequent systems joining the data sharing group use the same data set names, statistics, and backup flags as the first system. Therefore, even if you specify an asterisk (*) in the data set name table for either the primary or the backup data set name, the operator on subsequent systems is not prompted for a name.
