Explanation
XCF successfully processed a SETXCF COUPLE command
to change a couple data set option in the COUPLExx parmlib member.
In
the message text:
- typename
- The type for which the SETXCF COUPLE command was processed.
- INTERVAL REQUEST WAS ACCEPTED
- The failure detection interval for the system was updated to the
value specified on the SETXCF COUPLE command.
Note: - If USERINTERVAL function is set or defaulted to be disabled,
the effective failure detection interval is the greater one of the
spin failure detection interval derived from the EXSPATxx parameters,
and the user-specified INTERVAL (if any). If USERINTERVAL function
is enabled, XCF uses the user-specified INTERVAL as the effective
failure detection interval.
- Changes to EXSPATxx parameters cause new spin failure detection
interval to be computed, and then might cause the effective failure
detection interval to change.
- CLEANUP REQUEST WAS ACCEPTED
- XCF updated the time interval that the sysplex removing process
will wait for sysplex members to perform cleanup functions.
- OPNOTIFY REQUEST WAS ACCEPTED
- XCF updated the time interval that the system will use to determine
when to notify the operator when a system appears inoperative.
If an absolute OPNOTIFY value (nnnnn)
was specified, the effective OPNOTIFY interval used for this system
is the specified value. If a relative OPNOTIFY value (+nnnnn)
was specified, the effective OPNOTIFY interval used for this system
is the sum of the effective failure detection interval and the specified
relative value (but no more than 86400).
- MAXMSG REQUEST WAS ACCEPTED
- XCF updated the default maxmsg value. This value is used if the
MAXMSG keyword is not specified on the SETXCF START command.
- RETRY REQUEST WAS ACCEPTED
- XCF updated the default retry limit used by the system to monitor
a signalling path. This value is used if the RETRY keyword is not
specified on the SETXCF START command.
- CLASSLEN REQUEST WAS ACCEPTED
- XCF updated the default CLASSLEN value. This value is used if
the CLASSLEN keyword is not specified on the SETXCF START,CLASSDEF
command.
- PCOUPLE REQUEST FOR typename WAS ACCEPTED
- XCF defines a data set to be used as the primary couple data set
for the specified type. If the type is already operational in the
sysplex, then the data set specified is ignored and message IXC285I
is issued.
- ACOUPLE REQUEST FOR typename WAS ACCEPTED
- XCF defines a data set as an alternate couple data set. The system
issues message IXC251I when the switch to the new alternate couple
data set is complete.
- PSWITCH REQUEST FOR typename WAS ACCEPTED
- If the request is successful, XCF makes the alternate couple data
set the primary one, and stops using the current primary couple data
set.
System action
XCF changed the option as requested.
For
option ACOUPLE and PSWITCH, the system issues IXC251I
when the switch to the new alternate couple data set is complete.
For
option
PSWITCH, the system issues:
- Message IXC386I, if there is no alternate couple data set defined.
- Message IXC253I, if a primary or alternate couple data set failed
or is no longer in the sysplex.
Operator response
Notify the system programmer.
System programmer response
Update the COUPLExx parmlib member
to reflect the SETXCF request.
