Ah. Yeah. Still using 8i here. *sigh*. I've updated the script to allow you to set a variable to determine the resolution. It'll also now try and figure out the Oracle version on its own if it can. I also tried the script on the sample 9i trace that comes with Oracle::Trace, and it croaks. Looks like I expect a PARSE line immediately following the END OF STMT line closing each PARSING IN CURSOR section. I'll have to fix that. Can anybody shed any light on why there are no PARSE lines after END OF STMT in the following two trace sections: <snip> ===================== PARSING IN CURSOR #1 len=32 dep=0 uid=63 oct=42 lid=63 tim=1046586568955488 hv=4220954983 ad='55afb3bc' alter session set sql_trace true END OF STMT EXEC #1:c=16000,e=50842,p=0,cr=0,cu=0,mis=1,r=0,dep=0,og=4,tim=1046586568924750 *** 2003-12-17 15:44:32.818 ===================== PARSING IN CURSOR #1 len=24 dep=0 uid=63 oct=3 lid=63 tim=1046586594549056 hv=4113743782 ad='55b0eef4' select sysdate from dual END OF STMT dep=0,og=4,tim=1046586594548851 EXEC #1:c=3000,e=19436,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=4,tim=1046586594577246 FETCH #1:c=1000,e=1235,p=0,cr=3,cu=0,mis=0,r=1,dep=0,og=4,tim=1046586594583271 FETCH #1:c=0,e=13,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=0,tim=1046586594615367 *** 2003-12-17 15:44:50.253 </snip> Looking at Cary/Jeff's book, this is probably the answer: (page 104) "The kernel did not emit information about the parse of the ALTER SESSION command, because tracking wasn't enabled until after the parse had completed." That explains the first absence, but what about it not being there for the select statement? And what about that line beginning with "dep=0"...Is that normal? I looked through a cople of dozen of trace files I have (8i) and don't see any lines like that...Should I ignore such lines?
