If you enable sysplex autonomics, it is important that you ensure that the WLM policy for the OMPROUTE address space receives sufficient resources in relationship to other work that is being managed on the system. Under high load conditions, if not properly classified it is possible that OMPROUTE can trigger an autonomic response from the TCP/IP stack it has an affinity with, resulting in the TCP/IP address space removing itself from the sysplex group. Place the TCP/IP and OMPROUTE address spaces in the SYSSTC service classification. Classification in another service class leaves the system vulnerable to a sysplex distributor outage.
