Okay. So you just rewrite the tns etries of the apps nodes with lowercase (uatcdb), and that worked. According to the what I see in your outputs, this is expected and it is the fix. However; autoconfig will regenerate the tnsnames.ora and overwrite it. So that s completely expected :) but you got your workaround.
In order to make it permanent , you need to review your config. Check the db configuration and apps node context file and try to figure out where the autoconfig gets that value.. (that value is uppercase, but it should be lowercase)
-- I can't check it on a real EBS because currently I have limited connection to the LAB.. But I think you can find it and take the action for correcting it.. The issue is clear.
