Gettting DSV00119E - TCP/IP startup time limit exceeded starting CEMESRVR for the first time

Issue/Introduction:

We are installing CA Compliance Event Manager.
When we start the started task CEMESRVR for the first time after configuration, we get below error and the task ABENDs.

I followed the directions in technical document KB000032076 but that did not help:

Cause:

Datacom Server was started with PROTOCOL=BOTH which requires both CA CCI and TCPIP running on the mainframe.
Started Datacom Server with TRACEON=YES.
Trace showed that problem was CCI - got DSV00028E - Server ended, CCI/TCP failure in function:CCIINIT.
CCI was not running on the mainframe.

Environment:

z/OS
CA Compliance Event Manager
CA Datacom Server

Resolution:

Start Datacom Server with PROTOCOL=TCP.
