IXC700E

Explanation
While processing a JOIN or CREATE request, cross-system
coupling facility (XCF) detected that either the sysplex contains
the maximum number of groups or that group groupname contains
the maximum number of members.
In the message text: groupname
The name of the group which is of maximum size.
NO MORE GROUPS ALLOWED.
The sysplex contains the maximum number of groups specified in
the couple data set.
NO MORE MEMBERS ALLOWED IN GROUP groupname.
The sysplex contains the maximum number of members specified for
group groupname in the sysplex couple data set.

System action
If the JOIN or CREATE request
consumes the last available slot, the system continues processing
the request.  However, subsequent requests may be rejected due to
the lack of available slots.  If all of the available slots have already
been consumed, the request is rejected and the system issues message
IXC701I. Depending on the message text, one of the two possible capacity
problems is being identified.  The message is deleted if a primary
sysplex couple data with more capacity is brought into service.NO MORE GROUPS ALLOWED
Subsequent requests to join or create a member of
a new group will be rejected until such time as a group slot becomes
available.  If the primary sysplex couple data set is not formatted
to support the maximum possible number of groups, additional group
slots can be made available by increasing the number of groups that
is supported by the primary sysplex couple data set.  A group slot
can also be made available if all the members of an existing group
become undefined.
NO MORE MEMBERS ALLOWED IN GROUP groupname
Subsequent requests to join or create a new member
of the indicated group will be rejected until such time as a member
slot becomes available. If the primary sysplex couple data is not
already formatted to support the maximum possible number of members
per group, additional member slots can be made available by increasing
the number of members per group supported by the primary sysplex couple
data set.  A member slot can also be made available if a member of
the group becomes undefined.  Note:  The problem is not necessarily
restricted to the indicated group.  Other groups could experience
the same problem even though message IXC700E is not issued to explicitly
name them.

Operator response
Notify the system programmer.

System programmer response
Issue the DISPLAY XCF,COUPLE command
to display: The maximum groups and members defined in the sysplex couple data
set
The numbers of groups and members currently contained in the sysplex

 Use this information to determine whether the couple data set
allows enough groups and members for sysplex activity,
If you
decide that the couple data set should allow more groups and members,
choose one of the following: Switch the primary and alternate couple data sets by entering
the SETXCF COUPLE,PSWITCH command if the alternate couple data set
allows more groups and members than the primary one. Then format
a new alternate data set and issue SETXCF COUPLE,ACOUPLE=dsname.
 Make sure the data set is catalogued in the master catalog before
issuing the command.

Format an alternate couple data set allowing more groups and members
if one of the following is true: There is no alternate couple data set defined
The alternate couple data set does not allow any more groups or
members than the primary couple data set.

 After formatting a new alternate couple data set, do the following: Enter a SETXCF COUPLE,ACOUPLE command to define the new alternate
couple data set to XCF
Enter a SETXCF COUPLE,PSWITCH command to switch the primary couple
data set with the new alternate one.
