Introduction:
TSS9410E UNKNOWN CLASSNAME (CCICSCMD) FOR SVC (RACHECK ) We are receiving the above message when trying to start CICS TS 5.3. It is our first upgrade from CICS TS 3.2. I have applied RO75580 and RO86292 to address this issue, but they do not seem to be helping.  The ENFPARMS have also been updated to include CICSREL(65,70).  
Question:
I have applied the required Common Services maintenance for CICS/TS 5.3, RO75580.  Why am I receiving a TSS9410E UNKNOWN CLASSNAME (CCICSCMD) FOR SVC (RACHECK ) at CICS region startup?    
Environment:
Common Services r14.1 using the ENFCICS component to protect CICS regions using CA Top Secret release 15.0.  
Answer:
In addition to applying Common Serviices ENFCICS maintenance RO75580, also apply TSS maintenance RO87993 for CICS 5.3 compatibility.   For Common Services, issue the commands S ENF,,,REINIT and ENF REFRESH(CASESSI,CAS9CICS,CASXCICS).
