Creating a trace session

Create a trace session that can record event tracing information to the diagnostic log.

Prérequis

You must have the MANAGE ANY TRACE SESSION system privilege.

Any user trace events that are referenced in NOTIFY TRACE EVENT statements for the database must exist, unless the NOTIFY TRACE EVENT statement is contained in a TRY block that handles any errors if the user trace event does not exist. See Creating a user trace event.

Task

Execute a CREATE TEMPORARY TRACE EVENT SESSION statement.

For example:

CREATE TEMPORARY TRACE EVENT SESSION my_session
    ADD TRACE EVENT my_event, -- user event
    ADD TRACE EVENT SYS_ConsoleLog_Information -- system event
    ADD TARGET FILE ( SET filename_prefix='my_trace_file' );

The ADD TRACE EVENT clauses specify user and system trace events that are part of the session. The ADD TARGET FILE clause specifies the name of the logging target and, optionally, any parameters associated with that target.

Résultat

The trace session is created for the database, but it must be started manually.

Suivant

Start the trace session for the database.
