IXC287I

Explanation
This system found the couple data sets specified
in COUPLExx are not the same couple data sets last used by the sysplex
for this data type.  Since no systems are currently using this data
type, XCF cannot determine if it should use the data sets which are
specified in COUPLExx or those last used by the sysplex.
In
the message text: xx
The suffix identifying the COUPLE parmlib member.
typename
The type of data contained in the data set.When typename is
LOGR, see "LOGR
Couple Data Set Use Considerations" in z/OS MVS Setting Up a Sysplex for
more information.

System action
The system will list the data sets specified in
COUPLExx and those last used by the sysplex and then prompt the operator
to choose between the two sets.

Operator response
Notify the system programmer.

System programmer response
Check the COUPLExx specification to
determine if the couple data sets have been specified correctly. 
To avoid unnecessary processing during XCF initialization, COUPLExx
should specify the couple data sets currently in use by the systems
in the sysplex or those last used by the sysplex.
