Query for Client Errors
You can
query for database client errors using v$client_errors to search
for alert log related error data.
V$CLIENT_ERRORS shows the contents of the XML-based error log. For
example, if you want to search for errors related to client connection
tracing, you can query V$CLIENT_ERRORS. Also you can query
V$CLIENT_ERRORS if you want to pull the data from
these logs to another analytic solution for tracing errors. For example, if
you want to search for user errors, such as ORA-4021, you
can query V$CLIENT_ERRORS.
See V$CLIENT_ERRORS View for more information.
