The events_waits_current table has these columns: THREAD_ID, EVENT_ID The thread associated with the event and the thread current event number when the event starts. The THREAD_ID and EVENT_ID values taken together uniquely identify the row. No two rows have the same pair of values. EN...
The events_waits_current table contains current wait events. The table stores one row per thread showing the current status of the thread's most recent monitored wait event, so there is no system variable for configuring the table size. ...

region of memory. Considering that this crash has been consistently reported for TABLE EVENTS_WAITS_HISTORY_LONG, but never for TABLE EVENTS_WAITS_CURRENT, I suspect that the root cause is located in copy_events_waits(). The code uses a memcpy, which may copy different bytes of the 64 ...
In this example, you want to use the event bucketing target to count how many waits of each wait type occurred. To do this, you would specify the following options when you define the event bucketing target: filtering_event_name = 'wait_info' source = 'wait_type' source_type = 0...
Also, check whether the current Oracle configuration can be optimized regarding the I/O configuration according to Note 793113.If "log file sync" waits occur when you change large data volumes (for example, loading or compressing data), check whether indexes can be temporarily dropped or used ...
