DFHCF0409 CF structure strname could not be allocated in facility cfname, reason code rsncode.
Explanation
If a previous coupling facility data table server message DFHCF0403 indicated an IXLCONN failure because the structure could not be allocated, this message is issued for each coupling facility in which allocation was attempted to show the facility reason code indicating why structure allocation failed. If the reason code is known to the server, the name of the reason code is given (as defined in the MVS macro IXLYCONA, but without the 'ConaRsn' prefix), otherwise its decimal value is shown.
If the response indicates InvalidStructureSize, this means that the initial list structure size (specified on the server POOLSIZE parameter or in the CFRM policy INITSIZE parameter) is not large enough to contain the required structure control information. The size of the control information is affected by the number of list headers (determined by the server MAXTABLES parameter) and by the maximum structure size specified in the CFRM policy.
System action
The server is terminated.
User response
If further details are required, see the descriptions of the reason codes in the source of the MVS macro IXLYCONA which maps the connect answer area.
If the response was InvalidStructureSize, increase the initial structure size specification in the server POOLSIZE parameter or the CFRM policy INITSIZE parameter to ensure that there is enough space for data in addition to the structure control information. Also, check that the server MAXTABLES parameter and the maximum structure size specified in the CFRM policy are not unnecessarily large. See the Configuring for more information on how to estimate pool sizes.
