One must be sure to not just install the CA MAT 11.0 at BASE and then attemp to IVP. CTS 5.3 is not supported in CA MAT 11.0 at BASE!
Here are some indications that this is your situation:
A) When we initiated the CA MAT capture processing for CICS transaction under CICS V5.3 (Release 700), there is a message into CICS log:
TN0837S Unsupported CICS version 0503 e na log do MAT, a mensagem: TN0494W CICS routine not found for profile: xxxx.
Working with CICS support team we noticed that this message is issued by module T00CPLT.
B) Also Checking the CA MAT loadlib named: SYS2.MAT11.CEESPLD - we noticed that there are no routines for CICS 5.3 into it.
