EZZ0807I
GLOBALCONFIG ZIIP IQDIOMULTIWRITE IS IGNORED - HIPERSOCKETS MULTIPLE WRITE IS NOT ENABLED

Explanation

The TCP/IP profile specified the GLOBALCONFIG statement with a ZIIP parameter and the IQDIOMULTIWRITE subparameter to offload the HiperSockets™ multiple write workload to the IBM® System z® Integrated Information Processor (zIIP) on a System z9® or later server. However, HiperSockets multiple write support (GLOBALCONFIG IQDMULTIWRITE) is not configured.

System action

TCP/IP continues. The GLOBALCONFIG ZIIP IQDIOMULTIWRITE request is ignored.

Operator response

Contact the system programmer.

System programmer response

If you want to offload the HiperSockets multiple write workload to zIIP, specify both the ZIIP IQDIOMULTIWRITE subparameter and the IQDMULTIWRITE parameter on the GLOBALCONFIG statement and use the VARY TCPIP,,OBEYFILE command to process a profile that contains the statement.

If you do not want to offload the HiperSockets multiple write workload to zIIP, remove the GLOBALCONFIG ZIIP IQDIOMULTIWRITE subparameter from the profile to avoid this message in the future. See the GLOBALCONFIG profile statement in z/OS Communications Server: IP Configuration Reference for more information.
