M_SERVICE_REPLICATION table fields
We are in the process of setting up alerts whenever DR is behind by some particular number of log files we would be reporting an alert. Now we have selected these two field to report the difference.
Shipped Log Positon
Current Log Pos
The problem being is this we have given a condition where the difference between the two is greater than 100. What we wanted to understand is that what are the numbers indicated in the two fields. Is it a good indicator as to how we are achieving it.
We are getting frequent alerts where the log difference which is (last_log_position - shipped_log_position) "log difference is 245184" or some particular number. What i wanted to understand what exactly is a good number to start with for the alerting?
