Message Format

Each message is rated by severity :

notification: A normal activity, for example, the start up or shut down of the cache server or an event log rollover.
trace: Information that helps trace the activity of OracleAS Web Cache. These messages are particularly helpful in debugging caching rules. Messages with a severity level of trace are written to the event log file only when a Verbosity of Trace is selected in the event log configuration.
warning: An event which is abnormal or potentially a sign of a problem, but OracleAS Web Cache will continue to operate without any lack of service. For example, a request header included a malformed header, but OracleAS Web Cache interpreted it in some way and continued processing.
error: An event which can cause lack of service only within the request/response transaction. For example, OracleAS Web Cache cannot continue the transaction because of malformed request.
alert: An event which can affect a OracleAS Web Cache instance and can cause lack of service in a subsequent request/response transaction. For example, the origin server is not reachable or sufficient memory is unavailable. In many cases, the cache server will be shut down when an alert event is encountered.

In addition, OracleAS Web Cache provides messages, that are not included in this appendix, with severity levels of debug or internal error:

internal error: Contact Oracle Support for assistance.
debug: Intended for use only by Oracle Support.
