V$STREAMS_MESSAGE_TRACKING

V$STREAMS_MESSAGE_TRACKING displays information about LCRs tracked through the stream that are processed by each Streams client. Use the DBMS_STREAMS_ADM.SET_MESSAGE_TRACKING procedure to specify a tracking label that becomes part of each LCR generated by the current session.

When the actions parameter in the DBMS_STREAMS_ADM.SET_MESSAGE_TRACKING procedure is set to DBMS_STREAMS_ADM.ACTION_MEMORY, information about the LCRs is tracked in memory, and this view is populated with information about the LCRs. Currently, DBMS_STREAMS_ADM.ACTION_MEMORY is the only valid setting for the actions parameter in the procedure.
