Tracing in oracle db

I have been interacting with Oracle Support regarding the mystery of the SQL session tracing in our PROD env. Tracing is enabled on sessions coming from OIM and we don’t know how to deactivate it. This tracing of SQL sessions create large files on the database server’s filesystem. (/opt/oracle/admin/O4233/udump - files named *.trc)
This happens every time a connection is made. If we kill tracing on a connection, it reappears the next time a connection occurs from the OIM servers. Tracing is not enabled globally so it must be a SQL instruction issued by some code (ALTER SESSION SET sql_trace=’true’) or a JDBC connection config parameter.
Oracle is requesting the following:
· To verify that our code does not initiate the tracing
o we believe our code does not contain tracing
· To provide info about our WAS instance and verify that tracing is not enabled on the JDBC/connection pool in WAS.
o I searched through the JDBC config and could not find any setting.
Let me know if you can assist. Also raise your hand if you know of a setting that controls SQL tracing in WAS or OIM…
Thanks

How to enable tracing in Oracle Forms 10g

Hi Friends,
I am interested to trace my running oracle forms application. When I googled it, I got below useful information. But theory and practical has mismatch somewhere, I am not able to create the trace file(s).
**************************** Some Notes ****************************************************
How to Enable Tracing in Oracle Forms 10g
Enable Tracing from the url by adding the following to your forms url:
&record=forms&tracegroup=0-98,100-199 (note: item 99 causes some issues, so we are skipping it here. See the Oracle documenation for a description of what is being traced for each item.)
for example
[http://machine:port/forms/frmservlet?config=myConfig&record=forms&tracegroup=0-98,100-199]
You will get a trace file in the following location:
%ORACLE_HOME%\forms\trace\forms_xxx.trc where xxx is the forms session ID.
Open dos window and do the following:
set ORACLE_HOME=
set PATH=%ORACLE_HOME%\jdk\bin;%PATH%
set CLASSPATH=%ORACLE_HOME%\jdbc\lib\classes12.zip;%ORACLE_HOME%\forms\java\frmxlate.jar
java oracle.forms.diagnostics.Xlate datafile=%ORACLE_HOME%\forms\trace\forms_xxx.trc outputfile=%ORACLE_HOME%\forms\trace\html_xxx.html outputclass=WriteOutHTML
you will get a file html_xxx.html in your %ORACLE_HOME%\forms\trace directory.
I need information beyond this to make this practically successful.
Thanks in advance,

Tracing an Oracle user query as sys user

Hi,
i need to trace a particular user in Oracle database 11g as a sysuser. i want to know what all statements currently run by that user by generating trace file. How to do that?
Regards,
007

Or else use
execute DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION (sid=>507, serial#=>4957,sql_trace=>TRUE);
To disable:
execute DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION (sid=>507, serial#=>4957,sql_trace=>FALSE);
Or create trigger: whenever schemas login into db, trigger will be enablesd and trace all its activity in trace file and stop tracing when it logged off:
CREATE OR REPLACE TRIGGER SYS.set_trace
AFTER LOGON ON DATABASE
WHEN (USER like '&USERNAME')
DECLARE
      lcommand varchar(200);
BEGIN
      EXECUTE IMMEDIATE 'alter session set statistics_level=ALL';
      EXECUTE IMMEDIATE 'alter session set max_dump_file_size=UNLIMITED';
      EXECUTE IMMEDIATE 'alter session set events ''10046 trace name context forever, level 12''';
END set_trace;

Enable Tracing for Oracle 10g Forms

Hi All,
When I try to launch Oracle 10g Forms from web, it comes up, displays blank screen and goes away. Same happens for test.fmb.
How can I start tracing on Form Services or Oracle 10g Forms?
Any help would be appreciated.
Thanks in advance.

You possibly have a popup or ad blocker active. Forms will most likely not work with a blocker.

Tracing the Oracle client?

Hi there,
I have a problem where the client session drops from the database for no particular reason while half way through an insert. Could this be caused by the cpu being at 100%?
I can find no error messages in the database logs. Wha I want to know is if you can turn tracing on at the client end so when the connection goes drops it will right some sort of log?
The database is 9.2.0.7 in w2k server and the client has a full oracle 9i client installed on it.
TIA
Eddy

Does it show any errors or it simply "drops"?
Check the alertlog and user dump or db dump for related messages. If it simply dropsthe connection, check the listener.log. Also wafter the connection drops, the database will definitly be doing a rollback, so check any related activity in the database after it drops the connection.
Since you are inserting data, I would suggest you check whether the tablespace have enough space to take the new data.

ORA-04043 Error when oracle type is declared in a package

We have a package defining a type and a procedure which uses that type. The problem is - If the type is defined in a package jdbc fails with an error. If the type is declared outside the package everything works fine. The package is declared as
create or replace
PACKAGE TEST_ARRAY AS
TYPE COLTYPE_NUMTAB is table of number;
procedure Test_Procedure(some_var_name in COLTYPE_NUMTAB);
END TEST_ARRAY;My Jdbc call is made by declaring the type as "TEST_ARRAY.COLTYPE_NUMTAB".
Is there any different style/way of declaring this type?
Thanks

I tried tracing the oracle jdbc driver logs (we use the OCI jdbc driver) for the success and failure scenarios. Here are the logs

Though I am not the right person to interpret the jdbc logs hope it helps in troubleshooting the problem.

Tracing

Hi,
Oracle Database : 11.2.0.1
I am executing a procedure and want to enable tracing for it. Should i go for system wide tracing or session level tracing.
ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 1';
Is the above command OK to enable tracing in oracle?
Thanks

Hanging on Multi-threaded DB Partition to Oracle -cnt'd

Hi All,
Thanks for everyones replies to my plaintive calls for help.
Our problem was a hang of the "OpenCursor" call during dynamic
sql execution from Forte 3.0.M.0 to Oracle on NT.
The most useful suggestions included:
* Check for Errors in the SQL
- no errors found. SQL works fine from other clients
* Transaction around the entire piece of code
- already there.
* Ensure that the following line is used:
self.Session.RemoveStatement(statementHandle=dynStatement);
- it was already there.
* Try turning on log flags
Useful Log flags that might be helpful are
trc:db:1 - Cursor operations
trc:db:1:100 - Vendor specific cursor operation tracing
trc:db:1:200 - Checking cursor queues, fetching rows, cursor count
- we still get stuck in the OpenCursor, with no useful
information shown to see where the thread is stuck.
* Increase Cursor Count in Oracle - this was shown
not to be a problem. We did a separate test opening cursors
without closing them, and indeed hit the Oracle cursor limit,
but with this code we did not get back such an exception.
* We also set up tracing within Oracle, and the application proved to
be hanging inside Forte - before it had apparently reached Oracle.
* And a dumpstatus on the partition showed us stuck in the OpenCursor.
* It seems that indeed this problem is one with Forte and its
multithreaded DB Libraries, so our only soution was to revert back
to the traditional partition-based replication of single threaded
DB partitions. It only took a minute to revert back, but this was
disappointing from a hardware resources point of view. We have
not seen the problem again since making this change.
* One other question that came up - indeed 3.0.M.0 is a beta release,
and we are looking to move to 3.0.M.2 shortly. We had to move to M
quickly to resolve an ISAPI problem in L, but plan to move to M.2
as soon as possible.
Thanks again for all the replies!

@Sybrand - Funny you should mention Larry's boat - it happens to be moored about 200 metres from where I'm sitting here in Cape Town :-)
And yes, I will get in touch with sales for more clarity...
Thanks,
Andreas
*** Update
I called our 'Senior License Management Service Consultant' at Oracle and she confirms that Oracle do NOT take processor multithreading into consideration for licensing purposes.
So, our single quad core, multithreaded processor will be licensed as 4 cores, so will require 4 x 0.5 = 2 CPU licenses.
I guess Larry will have to drink cheaper champagne ;-)

Oracle Net

Hello,
When is it appropriate to set tracing on Oracle Net?

Hello,

I didn't even read the trace files, I sent them to Oracle Support.It's a shame you "didn't even read the trace files". Even without being a network wizard or knowing how to really read the file, you'd be surprised what you can pick out just by going on a "fishing expedition." You should try it some time.I've read them before. I've also taken etherpeek/wireshark captures. You're right, they can be quite insightful.
I should have been a bit more clear, but in the particular case above I had opened an SR on behalf of a client, and it was Oracle Support that requested the trace. Mentioning that I didn't read them was pretty irrelevant and makes me come off as lazy; I'm not sure why I did that.

Setting up embedded OC4J in JDev to use P6Spy jdbc driver to Oracle

I am currently working on an OC4J application using Oracle db, with JDeveloper. I'm having some trouble with the DataSourceUserManager, in that it appears to be emitting faulty SQL, but I don't know exactly what SQL is being emitted. Today, I'm trying to see if I can interject the P6Spy JDBC driver on the database client side so I can see exactly what SQL is being emitted. I've successfully used P6Spy in the past on other projects, so I believe it can work, although I didn't use it with Oracle before.
Unfortunately, I'm having trouble figuring out how to inform JDeveloper of the location of the driver jar. I've added P6Spy as a library to my application, and I've found several XML files in my workspace and in the JDev configuration which contain an "orion-application" element, which contains "library" sub elements, several of which I've added "library" elements to specify the location of the driver jar. Despite that, when the embedded OC4J starts up, I still get this in the messages window:
Error initializing data-source 'jdbc/OracleDS': DriverManagerDataSource driver 'com.p6spy.engine.spy.P6SpyDriver' not found
Note that this occurs while OC4J is trying to initialize my UserManager subclass.
I believe there is also some facility for turning on "tracing" with Oracle, but the person who knows about that isn't here today. It would be good if I could get P6Spy working today, so I can make some progress today (which is looking more unlikely by the second).

You must place the p6spy.jar into <oc4j_home>/j2ee/home/lib directory.
The datasources are initialized before any deployed application is started, and thus the p6spy.jar wont be in the classpath >when the appserver is started (if you put the jar in WEB-INF/lib).That's correct.
Another question -- have anyone managed to get p6spy to work with a ConnectionPoolManager in a BC4J-project?? I get a ClassCastException from oracle.jbo.server.OracleSQLBuilder because it tries to cast a statement into an OracleStatement.You need to build the project using SQL92 and Java Type Map.

ADF: How to find out which query has taken what time?

Hi,
I have an ADF application which has many SQL queried running on each button click/page load, so how to find out which query is taking what amount of time? So that i can identify the long running queries and modify them to improve the application performance.
Thanks in advance.

Hi,
As suggested by Timo,you need to start tracing on oracle.jbo package for getting the SQL queries.But I think the second option suggested by him would be better.You will have to override executeQueryForCollection method in VO Impl class .Pseudo code would be
@Override
Take start time
super.executeQueryForCollection
Take end time

Performance Issue in Import

Hi,
I have an import format where i am trying to import using an import integration script. the source is an Oracle database. While the import works OK when the record number is 100-200, the performance goes down when the count becomes 1000. for 3000 odd records FDM takes 30 minutes to load. for 10,000+ the application hangs.
I have checked the database setting for the FDM application and found that there are no separate tablespaces for data segement tables and work tables. all of them use the same table space. Could this be the only cause?? what other thing can I look at?
Also, I did some checks and foud that while the data s getting read properly in the recordset (rsAppend), the load to worktable is not happening. based on this I suspect that its a database set-up issue
Any help in resolving this would be greatly appreciated
-Shantanu

Hello Shantanu,
I personally use integration scripts into the 100k+ rows without issues. My imports take roughly 22 minutes. There must either be something with your script and how you are using it or as you suspected with your database.
At this point if you think it is a database issue I would encourage you to engage your DBA for tuning, packet tracing, and Oracle stats reports. Also please keep in mind that if the database isn't in the same datacenter then it might not be either the script or the database but the WAN performance.
Thank you,

Error loading external library

I have created a library in Oracle using a C library test.so in sun solaris.
This library contains string manipulation and memory management functions. When I call a function in this library through PL/SQL I get the error
ORA-06520: PL/SQL: Error loading external library
ORA-06522: ld.so.1: extprocPLSExtProc: fatal: relocation error: file /home/OraHome/8.1.7/lib/test.so: symbol endl__FR7ostream: referenced symbol not found
Anybody knows how to set the environment so that symbols in libraries located in other directories can be traced by Oracle.
Mohan

Hello
We have just come across the same problem. A .so library is
accesible (i.e. we have the adecuate permissions through Unix)
and the extproc procedure finds it, but we cannot access the
functions within it. We also get the (really strange) Bad Magic
error.
I see that you posted this problem a long while ago and I was
wondering if you've found a solution you could share.
Thanks,
