Sorry, but your statement that " for pl/sql you have no choice other
than dbms_profiler" is incorrect.
I have not challenged the usefulness of dbms_profiler. But I have now
been told twice that you can't use 10046 trace for pl/sql and if you
believe that you can't get useful information out of a 10046, level 8
trace for a pl/sql job then you are cheating yourself.
Let's look again at the original question.
For a batch job running pl/sql the user wanted to see:
-- the execution plans and costs for all the code it submits
I can't find the execution plans/costs using profiler. I could be in
for some education here, maybe it's there and I'm just not seeing it.
-- memory used
I can't find this using either tool.
-- cpu used
I can't find this in dbms_profiler output, but it is in 10046 trace.
-- time to complete.
Clearly available in both. However, a lot more detail of events
appears available in 10046.
I only continue to respond to this because I hate for someone who may have never used either tool to get the idea that if tasked with troubleshooting performance of a job that uses pl/sql they cannot use a 10046 trace. That would potentially be a huge part of a DBA's or a developer's world in which they would be limiting themselves. Is it the end all solution? Absolutely not. Is it going to help solve every pl/sql or sql problem? Absolutely not. Is it, in general, a useful tool to use with sql AND pl/sql? Absolutely!!

I think you have to distinguish between pl/sql and sql. 10046 deals
with
sql. for pl/sql you have no choice other than dbms_profiler (it used to
be
10928/10938 but oracle discourages that) and soon to be discontinued
dbms_trace.
So, if you ask me pl/sql I still stand by my answer and hopefully you
can
show us how to trace pl/sql using 10046.
