Oracle 188.8.131.52 Enterprise in a two server grid
In preparation for upgrading Oracle to 19c, the DBA installed Oracle patch 28553832.
After installing that patch, no one can access the Enforce console.
Firefox throws an error saying "PR_END_OF_FILE_ERROR".
Both Chrome and I.E. throw a time-out error.
Restarting the DLP services does not resolve this issue.
SQLPLUS does access the database.
The TNSListener is up.
Release: 15.5 MP2
Component: Oracle 184.108.40.206 Enterprise in a two server grid
It appears as if Oracle was not able to access the TNSListener after the patch was applied.
