Alter session set trace file identifier

These are things ONLY the application can reasonably give -- trying to do this at the database level is like trying to tell managment how good your system is performing using perform on windows or sar on unix. It is a tad "too low level". Alex, June 01, - am UTC. Although it does seem strange to me that the developers can't identify statements coming from their code? They can't do a text search for DML statements, anything?

Hi, Is it possible to trace at the user level,because application server has to use datbase user schema for connection??. Just for tracebility ,I can start only one connection say X ,and trace whatever is going from X to db. Write some sort of trigger As always your expert comment is appreciated. For Alex It's totally different ball game altogether when you go in 3 tier envirionment. I have seen over and over again people struggling to find out which sql is coming from where??

Now a day people write one piece of code and another they buy,they put them together and download another piece of code open source and again put them together. This is real world. No one has any clue what is happening in that piece of code. Yes this is real world So called open source Hope you understand : Cheers. June 05, - am UTC. Not sure what you are trying to do. It is actually quite easy to find stuff in code, assuming the code was written to be debugged, analyzed, tuned.

Hi, So you say,There is absolutely no way to trace if it is 3 tier architecture??. I have a db user called "x" and application server connects yes they have connection pool Using this user. Now I want to find out,what sql is being sent to db through that users.

Here I know which database user they are going to connect with. Now I want to find out if this approach will work ,if not what is the other way?. June 06, - am UTC. It is a good explanation, Tom. But I have a question right now. I am using db version 8. But the outcome is, i cannot find the trace file for edwardkfpang. On the other hand, i can get the trace file for 11, session. It seems that sql trace cannot captured those session that connect the db via SQLNet.

Recently we faced a situation where all the trace files got deleted from the udump before disabling the the traces. The filesystem was getting filled up with invisible trace files. This is when we needed a view or table to find out which all sessions had trace enabled and had missing trace files. Is there any way? Thanks Amar. November 18, - am UTC. Thus the trace was not good. Oracle 9. March 13, - pm UTC. Is that correct? July 13, - pm UTC. I assume that's the instance you're connected to?

Sorry I missed a statement in the question above. The following SQL produces the result above. A reader, August 14, - am UTC.

It aborts with insufficient privs August 14, - pm UTC. A reader, September 08, - pm UTC. Here is the example i used. September 09, - am UTC. A reader, September 09, - pm UTC. Tom, I am performing this on my desktop and i am the only one using it i cleared the trace files even before starting the database.

September 10, - am UTC. Hello Tom, Thanks for the wonderful site. I have a small doubt. I start trace at instance level using " alter system set events ' trace name context forever, level 12';" I noted the following a there is no trace file generated for that particular session which turned ON the tracing b even after I issue " alter system set events ' trace name context off';" The sessions that were started after the instance level tracing was ON , continues writing to the trace file.

Or is this how it behaves?? September 12, - am UTC. Tom, We are trying to convert one of our applications from 9i to 10g. While running one of our stored procedures that works in 9i we notice that in 10g it consumes all of the CPU and seems to go off to la-la land. I traced the session as you described and found that it gets to a very simple SQL statement with one bind variable and appear to never quit trying to bind the variable.

The trace file grows at the rate of about K per second or as fast as it can write. We shut the database down after a couple minutes but the last 15 million lines in the trace file are all the same. Have you ever seen anything like this. To make it even stranger, there is no data in the table it is trying to access. This obviously works in 9i, but kills the box in 10g. Any clues? September 20, - pm UTC. Not being able to see the code makes it hard. Chris, September 20, - pm UTC.

Wanted to add one detail That's a little bit of speculation on my part as I just discovered this. I'm sure it's not that simple, but thought it would be worth posting Thankfully I don't have to claim to be the author of the code that I didn't even think was valid, but evidently it is If you put the bulk collect in the cursor declaration which I didn't know you could do and actually have it compile , the process will go off and consume the CPU and never come back.

Here is a simple script that demonstrates this in Alexander the ok, December 12, - am UTC. Previous Next JavaScript must be enabled to correctly display this content.
