no connection to NIS database . Need help asap
You cannot apply data_engine-9.02HF1.zip to UIM 8.51 - it is not supported and causes this problem.
CUSTOMER HAD installed data_engine data_engine-9.02HF1.zip
BUT this is ONLY for UIM 9.02 and he is running UIM 8.51 and it caused failure of get_connection_string due to unrecognized enryption.
Once he re-deployed data_engine 8.50 the issue was resolved and the probes could be started.
