A quick bypass is to recycle the OPSUSS servers once CCI is up.
When OPSMVS starts before CCI at IPL set the USSMIN parameter to 0 in the OPS startup member so that no OPSUSS servers will be started. Then automate on the 'CAS9850I CAICCI TCP/IP server ready. PORT $$$$ ADDR %%%%%%' message.
When the CAS9850I message is issued with the PORT number of the CCITCPGW task, set the USSMIN from 0 to a value to start the OPSUSS servers.
