Hi. I didn't see this posted when I sent it first a few days ago, so here is my second attempt

I'm trying to use a tkprof against a few queries ran in parallel mode. I do alter session set sql_trace=true
to create a trace file in udump dir. Then I run tkprof trace-file output-file explain=/ sys=no.

What I get is a useless ( I think ) explain plan for a

parallel slave session instead of the one for a master

session. The plan looks something like this:

SELECT /*+ PIV_GB */ A1.C1 C0,A1.C4
C1,SYS_OP_MSR(SUM(A1.C5)) C2
FROM
(SELECT /*+ ORDERED NO_EXPAND USE_HASH(A3)
SWAP_JOIN_INPUTS(A3) */ A3.C0 C0,
A3.C1 C1,A3.C2 C2,A3.C3 C3,A2.C1 C4,A2.C2 C5 FROM ...

Is there a way for me to get the explain for a master session?

thank you

Gene
