TNS Slow Server Connect

Counter

TNS Slow Server Connect is a counter of all TNS server connect responses that exceed a threshold. A count of all TNS Slow Server Connects displays in the Overview counters of Expert View.

Expert Symptom

TNS Slow Server Connect events are automatically logged as expert symptoms. The Symptom Summary field provides information about the time elapsed for the server connect and the threshold value. For example:

Slow TNS server connect=298 ms (> 200 ms)

The threshold value for this symptom can be changed. The default value is 100 milliseconds.

This symptom applies to TNS servers only. If the response time is too long (exceeds the threshold), the symptom is recorded. For slow responses other than the ready message, see the TNS Slow Server Response symptom.
