Kindly share the IS details with fix levels. Also share the components currently installed.
From the look at the error message I see the Central User Manager is not configured properly.
– Run database component configuration successfully and check the central user manager configured from security>>user management page on IS
– Also check the JDBC pools if the central user manager is correctly configured and you are able to test (run)
– Make MWS up and running and access it via mws url
– Restart the IS and see if you still find the error
Update the thread with more details based on your findings.
