Resolution
In this scenario, the EZACONFG file had a GIVTIME value of 0 which was the fundamental cause of the "GIVESOCKET NOT TAKEN FOR SERVER" error and increasing it per the guidelines in this article resolved the problem: CICS Sockets Listener (TISRVLIS/TISRVMSL) timeout parameters.
However, the "autoinstalled" messages in the CICS log also show that CICS Autoinstall is being used to define the generated Gen application server programs as well as the Gen TIR* runtime programs. That could cause the first transaction to be slow in starting up. The TAKESOCKET would be executed after the runtime in TIRMMDLL is invoked but the log shows the GIVESOCKET NOT TAKEN is issued before the runtimes are autoinstalled. So it was advised not to use Austoinstall and instead to create program definitions (PPT) for the Gen server and runtimes to speed up the server execution.
NOTE: Autoinstall is a good way to prevent failures, so good for a Test system but not really for Production or a system where response time/performance is an issue.
