Our customer have one job which runs daily and one of the sqls which executes
like 500 times had 5 odd executions where it runs slower and most of the time
is being spent on "SQL*Net more data to client" . Normal run times are like few
seconds and the longer run times are like 1 hour or so.
For other executions we dont see that wait event being a problem.
What kind of tracing can we do to go in depth of the issue. I want to be sure
before i suggest some tuning at SDU sizing level etc.
Because we cannot predict when the slow run of the query will happen we cannot
wait for it and then run strace etc exactly at that time ,Basically we will
have to automate the tracing step.
