Hello All,
We have a 12.1.0.2 RAC database and when we read the last AWR report, we noticed that the interconnect latence was high.
Here are Interconnect Ping Latency Stats results from AWR :
Here the result from target 1 :
Target Instance : 1
500B Ping Count : 71
Avg Latency 500B msg : 0.46
Stddev 500B msg : 0.14
8K Ping Count : 71
Avg Latency 8K msg : 0.43
Stddev 8K msg : 0.14
I think everything is ok. As I understood, the server pings itself.
Here the result from target 2 :
Target Instance : 2
500B Ping Count : 71
Avg Latency 500B msg : 13.25
Stddev 500B msg : 45.56
8K Ping Count : 71
Avg Latency 8K msg : 13.26
Stddev 8K msg : 45.53
Here is the problem, the values are pretty high. According to Oracle documentation, the latency should be less that a milliseconds (such as target 1).
Do you think there is a problem ? Where should I look in order to solve it ?
Many thanks !
Cheebea.
