Description:

You have these messages:

+DFHAP1203I CICSI1 Language Environment is being initialized.
TSS9410E UNKNOWN CLASSNAME (MCICSPPT) FOR SVC (RACHECK)
+DFHAP1200 CICSI1 A CICS request to the Language Environment has failed.
Reason code '0011020'.
+DFHAP1208 CICSI1 Language Environment cannot support the Cobol language.
+DFHAP1209 CICSI1 Language Environment cannot support the C/C++ languages.
+DFHAP1210 CICSI1 Language Environment cannot support the PL/I language.
+DFHAP1211I CICSI1 Language Environment initialization completed.
TSS9410E UNKNOWN CLASSNAME (MCICSPPT) FOR SVC (RACHECK)
+DFHSI2813 CICSI1 Program DFHRCEX cannot be found.

You can't no longer start CICS 4.2.

Solution:

The error message you reported is a direct consequence of not specifying the correct CICSREL parameter for the pertinent CICS release, in this case, CICSREL(67).

After adding 67 to CICSREL and restart ENF, CICS 4.2 can start without TSS9410E message.
