A collection is data collected for events that occurred while an instrumented product was running. ORACLE_TRACE_COLLECTION_NAME specifies the Oracle Trace collection name for this instance. Oracle also uses this parameter in the output file names (collection definition file .cdf and data collection file .dat). If you set ORACLE_TRACE_ENABLE to true, setting this value to a non-null string will start a default Oracle Trace collection that will run until this value is set to null again.
