IXC373I

Explanation
A COUPLExx parmlib member FUNCTIONS statement or
a SETXCF FUNCTIONS command specified that one or more installation-controllable
optional functions are to be enabled or disabled. This message reports
the results of that request.Optional functions reported as NOT RECOGNIZED
are not defined at the same release or service level of the issuing
system. Possible reasons are as follows:A COUPLExx parmlib member is shared between systems at different
levels.
A SETXCF command is routed to systems at different levels.
An optional function name is misspelled.

Optional functions reported as NOT SUPPORTED
FOR SETXCF COMMAND cannot be enabled and/or disabled dynamically using
the SETXCF FUNCTIONS command. For example, the SETXCF FUNCTIONS command
can be used to disable the CRITICALPAGING function but cannot be used
to enable it.
In the message text: action
One of the following actions:ENABLED
The named optional functions have been enabled on the  issuing
system.
DISABLED
The named optional functions have been disabled on the issuing
system.
NOT RECOGNIZED
The named optional functions are not defined at this release or
maintenance level.
NOT SUPPORTED FOR SETXCF COMMAND
The SETXCF command cannot be used to take the specified action
for the named optional functions.

function
The optional XES/XCF functions:DUPLEXCF16
SYSSTATDETECT
USERINTERVAL
DUPLEXCFDIAG
CRITICALPAGING
CFLCRMGMT
COUPLINGTHININT

For descriptions of the listed function names, see topic "The
FUNCTIONS Statement" in  z/OS MVS Setting Up a Sysplex. 

System action
The system begins exploiting functions that have
been enabled (subject to the establishment of any other prerequisites
that are required for their use), or stops exploiting functions that
have been disabled. The system takes no action with respect to unrecognized or unsupported functions.

Operator response
Take the following actions if any optional
functions are reported as NOT RECOGNIZED:If the message was issued in response to a SETXCF FUNCTIONS command,
verify that the reported function names have been spelled correctly.
If not, reissue the command if not. If all functions are spelled correctly,
contact the system programmer.
 If the message was issued in response to a COUPLExx FUNCTIONS
statement, contact the system programmer.

System programmer response
If any optional functions are reported
as NOT RECOGNIZED, verify their applicability to the system issuing
the message.  Correct the COUPLExx parmlib member if necessary.  No
action is required if the parmlib member or command was simply processed
by a downlevel system.
If any optional functions
are reported as NOT SUPPORTED FOR SETXCF COMMAND, update the COUPLExx
parmlib member FUNCTIONS statement to enable or disable the functions
on subsequent IPL.
