Although the member systems of a multisystem RRSF node do not communicate
with each other via RRSF functions, each system in the multisystem node must
issue TARGET commands describing the other systems in the multisystem node.
RACF needs this TARGET information if you reconfigure the multisystem node with
a different main system. The systems can share a common RACF parameter
library that contains all of the TARGET commands required.
It is possible to define a multisystem node that contains only one system. This
configuration might be useful as a migration path.
The RACF support for multisystem RRSF nodes includes:
Enhancements to the TARGET command to allow system programmers to
configure multisystem RRSF nodes
Enhancements to the RESTART command to allow operators to restart
connections to systems in multisystem RRSF nodes
A new naming convention for the workspace data sets used by RACF for RRSF
communications
A new connection state, the
defined
state

OS/390 Enable and Disable Functions
OS/390 provides a registration service to enable and disable features. RACF for
OS/390 Release 2 supports this enable and disable function.
Entries in the IFAPRD
xx
parmlib member specify which features are enabled and
disabled. When you install OS/390 Release 2, make sure that an entry exists in
IFAPRD
xx
to enable RACF. If RACF is not enabled, RACF initialization will not
complete, and RACF will not provide security for the system.
For more information, see “Enabling RACF” on page 27.
Year 2000
RACF dates are 3-byte packed decimal fields in the form
yydddF
. This format does
not allow the first two characters of the year to be specified. In the past it has been
acceptable to assume that the date is in the twentieth century, and that the first two
characters of the year are '19'. However, as the end of the twentieth century
approaches, support is required for dates where the first two characters of the year
are '20'.
RACF now considers a date with a
yy
value of 70 or less to be in the year 20
yy
,
and a date with a
yy
value greater than 70 to be in the year 19
yy
