Why login fails with error oacore:-

The likely cause of this issue is CPU patch. Maybe we are facing this issue due to CPU patching, patches were applied during quarter patching activity after that oracle e business suite login page not opening.

As per my understanding to eliminate this issue, we need to apply these patches on lower instances, and then it should be tested properly the same. After that, we are good to go on production environment.
