Optimizer RFC error

Hi,

I have installed gateway and SCM 7.0 ehp3 optimizer.

While testing RFC connection in SCM system, I get "CPIC-CALL, ThSAPOCMNIT; cmRC=20 thRc=2

No storage allocation available error

At the optimizer gateway I can see the error " secinfo denied : user = abc ,USER-HOST = hostname , HOST= hostname, TP= exec file path

How to resolve this issue..what has to be done with secinfo in the SCM system exactly or it has to be corrected in the optimizer?

I will appreciate your help and guidance

Thanks in advance
