Sql statement appear twice in trace file
Hi all,
Just a little confused on why my sql statement appear twice in the sql trace file.
the following is the sequence of steps to reproduce this.
1. Enable sql trace in another session, say session B
exec dbms_monitor.session_trace_enable(38,13330,TRUE,TRUE);2. Execute the following sql in session B
select * from hosts where hostname = 'host19'3. Disable sql trace
exec dbms_monitor.session_trace_disable(38,13330);I used TKPROF to parse the trace file
tkprof DEV_ora_20621.trc DEV_ora_20621.out sys=noThe output is
SQL ID: bcpw6ttb0xbqs
Plan Hash: 0

1 INDEX RANGE SCAN IDX_HOST01 (cr=2 pr=0 pw=0 time=0 us cost=1 size=0 card=1)(object id 78193)Why the sql is showing twice?
I think the correct one would be the second since it's reporting the fetching of 1 row.
Does anyone understand this?
Cheers,

Could not reproduce this in my 10.2.0.4.0 environment. Whats your Oracle version?

High SQL*Net message values in trace file.
Hi all,
This is my first post here. I will try to more less describe the problem i am facing.
Any help is more than welcome!
I am facing some performance issues with application. Slow GUI. I run some tests, i tracked the session. what i found in trace file is:

Look at Max. Wait and Total Waited columns. Is it possible to safely tune it by changing SDU in sql*net ? and if so, is it needed to change the SDU value on client and server sides ?66ff73bb-87bd-4c84-bada-0141fb25344b wrote:

When you start with the wrong question, no matter how good an answer you get, it won't matter very much.
you do NOT have any problem; just a useless observation. -

After this, i checked in user dump directory. The trace files are generating... But this sql code is not appearing in the trace files...
Am i missing anything... Any help is appreciated.
ThanksThis may happen when the trace file is not completely closed.You may try again doing like this,
alter session set sql_trace=true;
select * from emp;
alter session set sql_trace=false;After this,disconnect and exit from your session as well. This should close the file completely and you should be able to see your command in it.

Capture all SQL statements and archive to file in real time
Want to Capture all SQL statements and archive to file in real time?
Oracle Session Manager is the tool just you need.
Get it at http://www.wangz.net
This tools monitor how connected sessions use database instance resources in real time. You can obtain an overview of session activity sorted by a statistic of your choosing. For any given session, you can then drill down for more detail. You can further customize the information you display by specifying manual or automatic data refresh, the rate of automatic refresh.
In addition to these useful monitoring capabilities, OSM allows you to send LAN pop-up message to users of Oracle sessions.
Features:
--Capture all SQL statement text and archive to files in real time
--Pinpoints problematic database sessions and displays detailed performance and resource consumption data.
--Dynamically list sessions holding locks and other sessions who are waiting for.
--Support to kill several selected sessions
--Send LAN pop-up message to users of Oracle sessions
--Gives hit/miss ratio for library cache,dictionary cache and buffer cache periodically,helps to tune memory
--Export necessary data into file
--Modify the dynamic system parameters on the fly
--Syntax highlight for SQL statements
--An overview of your current connected instance informaiton,such as Version, SGA,License,etc
--Find out object according to File Id and Block Id

Hi All
I have 3 statements and I am writing some thing to a file using UTL_FILE.PUT_LINE after each statement is over. Each statement takes mentioned time to complete.
I am opening file in append mode.
statement1 (takes 2 mins)
UTL_FILE.PUT_LINE
statement2 (takes 5 mins)
UTL_FILE.PUT_LINE
statement3 (takes 10 mins)
UTL_FILE.PUT_LINE
I noticed that I am able to see contents written by UTL_FILE.PUT_LINE only after statement3 is over, not IMMEDIATELY after statement1 and statement2 are done ?
Can anybody tell me if this is correct behavior or am I missing something here ?Calling procedure must terminate before data is actually written to the file.
It is expected & correct behavior. -

Run sql statement from batch file
How can we execute SQL Statement using Batch file???
I did a test.
create batch file test.bat
sqlplus "username@db /pass" @\script.sql
script.sql file has following statement
select sysdate from dual;
exit
it is working but I want to call sql statement in the same batch file instead of calling .sql script file. how can I do that any idea..This is very easy in unix shell scripting, but AFAIK, not available with Windows. It's a function of how the shell/command processor handles input redirection.

Trace File Created Upon Execution of "alter system kill session sid, serial# immediate;"
A problem within a third-party application is causing it to create and abandon Oracle sessions. At times three hundred or more abandoned sessions accumulated in the instance. The software company is working on the problem. Oracle's background processes will get rid of those sessions after several hours, but at times there were so many they caused the server to start using paging space. We wrote a SQL*Plus script to identify the abandoned sessions and kill them with command "alter system kill session <sid, serial#> immediate;". We automated the execution of the script a week ago. Today I noticed that in my udump directory an Oracle trace file has been created each time our script kills a session. A single trace file is created regardless of how many sessions are killed. No errors appear in the trace file.
Is the creation of these trace files an indication that problems have occurred or are they there for information only?
Since I know how and why the sessions are being killed, is it safe to ignore the trace files?
Thank you,
BillThe OS is AIX 5.2. The database server is 10.2.0.2. We are in the processing of upgrading to AIX 7.1 and database server 11.2.0.3.6.
The script does not enable tracing for the SQL*Plus session.
Below is the alert log message from a session killed at 11:22, and the corresponding trace file created at that same time:

Oracle Trace File generation for a session
Hi,
I am using oracle 10g(10.2.0.5) in RHEL5 server. i have used the exec dbms_system.set_sql_trace_in_session(147,3,TRUE); statement to trace a particular session. i am able to trace successfully but i have created a new table in that session where i am not able to find any create table statement in the generated trace file but i can find the insert statements which i performed on the newly created table in the trace file.
Does DDL statements not recorded in the trace events???
Regards,
007Hi;

We seem to be having the problem that an application has 2 threads trying to write to the same row of a table. What I dont understand is that in the insert statement shown in the trace file the data after the VALUES word is not proper data. I dont know if this indicates an application problem or if this is due to the format of the trace file :-
INSERT INTO GDOC_ALERTS_STATUS (ActionTime,ActionCode,ServerSerial,ServerName,Serial) VALUES (:actiontime,:actioncode,:serverserial,:servername,:serial)
The following deadlock is not an ORACLE error. It is a
deadlock due to user error in the design of an application
or from issuing incorrect ad-hoc SQL. The following
information may aid in determining the deadlock:
Deadlock graph:
---------Blocker(s)-------- ---------Waiter(s)---------

[10g - XE] Why is my disk full of trace files?
Just in case there's another silly person like me out there who encounters this problem...
I have XE 10g installed on my local machine (Windows XP), as my own personal test environment.
My computer was acting really weird yesterday, then today I got an error while using Excel that my disk was full.... and after some investigating, I discovered that I have 39 GB (gasp!) of trace files! These are all located in the directory C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\trace
...and some of them are quite large (obviously, since I have 39 GB of them...); one of them by itself is 2 GB.
Almost all of the files are named like: sqlnet_trace.txt_3132_1.trc And, for example, I already have 5 trace files from today, totaling 15 MB.
I vaguely recalled setting my trace level to 16 or SUPPORT a LONG time ago, and funny thing, I couldn't remember changing it back to OFF.
So, if you've been silly like me, check your sqlnet.ora file, and set TRACE_LEVEL_CLIENT=OFFThanks for the tip. I checked listener.ora, and it doesn't appear that any trace files are enabled there. I don't know what Net manager is.
At least in this case, the server/database is just my personal PC, so the only person it impacted was me. It took 7 months for the trace files to grow to that size with just me using the database, so I can only imagine what it would do to a database in an actual environment. -
Trace file created for the wrong session
DB version : 10.2.0.3.0
OS version: Solaris 5.10
2 node RAC
Using DBMS_MONITOR.SESSION_TRACE_ENABLE, I have been trying to trace an oracle session spawned by a C++ application.
So, i determined which instance this session is connected by querying gv$session. I logged in as SYS in that instance's Node and then issued
execute dbms_monitor.session_trace_enable(4371,98124, true, false);After enabling, i saw new A trace file being generated. But this trace is actually tracing SYS's session which executed dbms_monitor.session_trace_enable and not the session (4371,98124) !!! I tested few basic queries in SYS's session like
select sysdate from dualAnd i can see all these queries appearing in the trace file. What could be the cause of this issue?
I have noticed that
SHARED_SERVERS = 1 on both nodes. Is this causing this weird issue? For tracing, If i disable SHARED_SERVERS using
alter system set SHARED_SERVERS = 0
will it cause any connection problems for the client applications because of their tnsnames.ora file setting?John_75 wrote:
Thank you DBMS_DIRECT.
trace is enabled only on the instance to which the caller is connected
So, how do i enable tracing for sessions spawned by Java or C++ applications.
According to the documentation, i can use DBMS_MONITOR for tracing applications
http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/sqltrace.htm
Your 2 node RAC has two instances (e.g. INST1 and INST2). My understanding of that is that with the above command, to be able to trace session 123 connected to INST1, your SYS need to be connected to INST1. To be able to trace session 456 connected to INST2, your SYS need to be connected to INST2. -
Excuting multiple sql statements
Hi to everybody.
I'm quite new to Oracle even if i have quite a big experience with MySQL and SQL commands. I'm facing a problem that I suppose it is a really basic one.
I received a dump of an Oracle database in a .sql format. I mean that both the schema and the data are build through a large number of sql statements. In particular the schema is made through a lot of "create table ..." while the data are built through "insert into..". My need is to import these database in a fresh Oracle database Oracle 10 g XE.
I've installed it on a Debian system and i can succesfully execute a single SQL command both through the web interface http://localhost:8080/apex and logging as oracle user through the sqlplus username/passwd command.
My problem is that the data are split on about 12000 SQL "INSERT INTO.." so executing all of them one by one could be a little annoying :-)
<u>So I'm asking if there is a way to instruct Oracle to execute multiple SQL statements reading it from a file (like MySQL does for example).</u>
I' m considering to write a script to do it if there's no better way. I know that there're better way to dump databases in Oracle but I can change the .sql format since it is the only one that I got.in SQL*Plus you can execute a SQL file with the start command or it's shorthand version @:SQL> start filename.sql
or
SQL> @filename.sql -

PavelDid you try to tkprof a 10053 trace ?
That is not going to show anything. 10053 traces are meant to be read as they are. tkprof is there to deal with 10046 traces.
