Have used Gen TCP/IP Direct Connect for CICS i.e. CICS Sockets Server Listener (TISRVLIS) and CICS Multi Socket Server Listener (TISRVMSL), for some time without problems. However this LMP license message has started to appear:CAS9013A Product 4F about to expire or is expired and is in use
Gen TCP/IP Direct Connect for CICS
The LMP product key 4F corresponds to the Gen TCP/IP Direct Connect for CICS component which has always required an LMP license, but in the past the license check was not working correctly.
When IBM SCRT features were added to Gen 8.6 PTFs released in November 2020, a license check fix for the TCP/IP Direct Connect Listeners for both CICS and IMS was implemented at the same time - SO15047.
This is also covered under the Gen 8.6 Customize Middleware doc. page under Customize for TCP/IP e.g. for CICS:
===
Gen TCP/IP Listeners have been modified to check the correct LMP code and will no longer produce the message "TIRM130 LMP (license check) HAS NOT BEEN INITIALIZED" but instead will add an entry to the Sub-Capacity Reporting Tool report produced by IBM.

That PTF change is also included the Service Update 2111 PAX file released in November 2021 - see Gen™ 8.6 > Release Notes > New Features section "Service Update Level 2111 for z/OS Availability"
