Hi,
On 12.1.0.2 when using Data Guard or Far Sync
On the primary database I see a new wait event: "Redo Transport MISC"
I didn't find any information concerning this event (google or my oracle support)
I also see that the values of this event is similar to "SYNC Remote Write" (Used to track the time spent by LGWR doing SYNC RFSWRITE operations)
Here is the top of Background Wait Events section of my AWR
Total Avg
%Time Wait wait Waits % bg
Event Waits -outs Time (s) (ms) /txn time
-------------------------- ----------- ----- -------- ---------- -------- ------
db file parallel write 28,744 0 271 9.43 0.1 26.9
Redo Transport MISC 161,151 0 243 1.51 0.7 24.1
SYNC Remote Write 161,150 0 164 1.02 0.7 16.3
Do you have an idea ?
Thanks
Yossi
