yes
what you said was correct for OPTIMIZER PARAMETER.
But in the case of sql_trace parameter it is behaving
in different manner.
trace at db level is false. so in v$param it is false.
i logged into scott/tiger and set the sql_trace to
true.
the strange thing i found was when i issue
show parameters sql_trace from scott it is showing
sql_trace=false
why?
