If systems in an RRSF network have different versions of the dynamic parse specification data set (IRRDPSDS) installed, commands that run successfully on one system might fail on another one. You can run with different dynamic parse versions as long as you do not try to add or alter a profile using a segment field that exists in one system's IRRDPSDS member but not in another.

When an RRSF node attempts to establish communications with another RRSF node, RACF® determines which versions of the dynamic parse specification data set (IRRDPSDS) are installed on each node and issues a warning message if they are different. You can determine what level of the dynamic parse specification data set your system is using by issuing a RACF SET LIST operator command.

To determine the contents of the dynamic parse table, issue the IRRDPI00 LIST command. See Dynamic parse and IRRDPI00 for more information about the dynamic parse table.
