SQL trace query parameters

Hi,
I'm sending SQL queries to Oracle through JDBC, and I want to debug these SQL queries with SQL trace.
My problem is when i want to view the trace files via tkprof, my queryies do not show the parameters.
For example: SELECT * FROM mytable WHERE mycolumn = :1
I would like to see the value of :1.
How can i do that?
Thanks

    Using shared directory. Use the parameters dump to point to it
    is it possible to create them on client side instead?
    No
    . :-) any help with my english is wellcome :-) .does this mean sharing user_dump destination at linux level and then mounting it from client machines ( win xp )?is there any doc on this?

  • Can I set up SQL Trace or Audit to connect to servers

    I have a server (2003) with SQL (2005) on it. 
    If i install MS SQL Management Studio 2012 on my PC, can I audit what SQL on that server is doing by connecting to it from the PC ?
    Or would it be better to set up SQL Trace on the server itself ?
    Thanks
    Pete

    So if I install SSMS 2012 on my PC, I can connect to the databases on different servers from 1 place. 
    Yes, as long as there is network connection.  In SSMS open up the Registered Servers window and register all servers:

  • "Define query parameters" popup in Dataset properties - Refersh field, not displayed for Sps in SSDT 2010 (Works fine in BIDS)

    When we upgraded our SSRs projects to 2012, we are facing an issue in Data tools environment.
    When we click REFRESH FIELDS button in Dataset properties, With query type as SP (For all our sps), the "Define query parameters"  popup is not displayed. 
    When we checked the SQL Profiler for queries executed at back end , NULL values are used for parameters.
    But when we Used the QUERY DESIGNER button, and clicked execute for sp, the popup comes.
    For User defined Functions, the Popup comes correctly.
    In BIDS, still we can open the RDLs and do the operations correctly
    Please advice

    Dear Wendy Fu
    My Scenario is different.
    In Query Designer, Every thing is fine (Parameter Popup is coming, and fields are populated under data set)
    But what we need to do is
    1, Select Query Type As SP
    2, Select the required SP
    3, Click Refresh Button
    4, A "Define
    query parameters" window popsup
    5, Provide values and click Ok
    6, Fields will be populated under the dataset
    The issue we face is that, we are not getting the  Define query parameters popup,
    Hence NULL values are passed to execute the sp, to retrieve the fields set.
    The Work around we are using now is editing the sp, and use
    set @Parameter = Value
    for each parameters in sp, and then we get the fields populated under dataset, when we click refresh.
    The issue exists in both  MSDT for
    Visual studio 2010 &  MSDT for  Visual studio 2012.
    But every thing is fine in BIDS with VS 2008 Shell for the same RDL

  • OCCI/ODBC application sql trace failure...

    Hi,
    I was doing the sql*net trace for an OCCI/ODBC Application writen in c++. I have an InstantClient on my PC. I was trying to access the Oracle through my C++ program to
    compare the performance of OCCI and ODBC.
    I was using the Oracle 10g(ver10.2.0.1.0 ), Oracle instant cilent(win32-10.2.0.3-20061115), and VS 8.0.
    TNSNAMES.ora:
    ORCL =　　
    　　(DESCRIPTION =
    　　(ADDRESS_LIST =
    　　(ADDRESS = (PROTOCOL = TCP)(HOST = host_name)(PORT = 1521))
    　　(CONNECT_DATA =
    　　(SERVER = DEDICATED)
    　　(SERVICE_NAME = ORCL)
    (SID = ORCL)
    LISTENER.ORA:(It was created by net manager.)
    SID_LIST_LISTENER =
    　　(SID_LIST =
    　　(SID_DESC =
    　　(GLOBAL_DBNAME = ORCL)
    　　(ORACLE_HOME = F:\oracle\product\10.1.0\Db_3)
    　　(SID_NAME = ORCL)
    LISTENER =
    　　(DESCRIPTION =
    　　(ADDRESS = (PROTOCOL = TCP)(HOST = HOST_NAME)(PORT = 1521))
    The sqlnet.ora file was writen to trace the client sql. Fortunately, my C++ program can access the oracle and get my result back successfully. In the same time, the trace files
    can be created, but when using the tkprof tool to explain it, it comes to the file with useless information.
    One of the *.trc file explaind by tkprof tool:
    Sort options: default
    count = number of times OCI procedure was executed
    cpu = cpu time in seconds executing
    elapsed = elapsed time in seconds executing
    disk = number of physical reads of buffers from disk
    query = number of buffers gotten for consistent read
    current = number of buffers gotten in current mode (usually for update)
    rows = number of rows processed by the fetch or execute call
    Trace file: ora21763.trc
    Trace file compatibility: 8.00.04
    Sort options: default
    1 session in tracefile.
    0 user SQL statements in trace file.
    0 internal SQL statements in trace file.
    0 SQL statements in trace file.
    0 unique SQL statements in trace file.
    327 lines in trace file.
    Finally, I got TNS-12518 TNS-12564 error. I tried to add DIRECT_HANDOFF_TTC_LISTENER=OFF, but it didnt work. I traced the listener, the error occured in the listener.trc "
    ntt2err: soc 464 error " and " nsbequeath: error reading REDIR/NSE msg".
    I just cann't get the right trace file and cann't sovle the two errors(TNS-12518 TNS-12564). Can somebody give me some advices, please.

    Hi,
    The TKPROF facility accepts as input an SQL trace file generated when SQL Trace has been turned on for the system or a session, not a SQL*NET trace file. A SQL*Net trace file is a dump of raw data packets and communications at the SQL*NET layer. If you want to get performance statistics from SQL beign executed by your application, then you need to turn on SQL Trace not SQL*MET tracing.
    To enable SQL trace at the system level, you need to execute:
    alter system set SQL_TRACE=TRUE
    The NS-12518 TNS-12564 normally means you are running into some sort of resource deletion issue. This can be caused by various things. Make sure you are properly cleaning up and closing sessions in your application.
    Are you performing some sort of stress test or have you just written a Multi-threaded test harness that executes different types of SQL with OCCI/ODBC?
    HTH

    Hi Floks,

    HI,
    <b>SQL Trace Use:</b>
    The SQL Trace function is an on-demand log of selected SQL statements that are issued against the database through the Open SQL Engine. The SQL Trace can be switched on or off dynamically. The log format is database independent. Besides the SQL statement text, each log record contains information about the point in time when the statement was executed, its duration, its input parameters and results (where applicable) as well as context information.
    <b>
    Features</b>
    The SQL Trace is especially useful for:
    Development
    SQL Trace can help JDO, enterprise beans, servlet and JSP developers to learn which kind of database accesses their code produces.
    1.      Performance analysis
    Typically, performance issues are caused by inefficient database accesses. In this case SQL Trace can be used to show the issued SQL statements and their duration, thus helping to identify inefficient SQL statements.
    <b>Activities</b>
    Typically, you should use the SQL Trace when you need to check the behavior of a particular application. This is the following scenario:
    Look at the below links, you will get the idea

    Hi,
    i did the homework, but some how i dont seem to understand what oracle is doing behind
    esp with hints like
    select /*+ leading(v1 v2) use_nl_with_index(v2) */ count(v1.val)
    /*+ no_parallel(t) no_parallel_index(t) dbms_stats

      substrb(dump(max("XXX"),16,0,32),1,120),i havent used this things any where in my program, but still they are used,
    so i got confused, can you throw some light on this issue,

  • Regarding SQL trace

    Hi all,
    I want to run a SQL trace for processing of CREMAS IDOC's ( custom Functional module)  and i want to see which all tables or SQL statement is taking more time .
    Can you tell me procedure to run SQL trace.

    HI,
    Here are the 2 good links
    http://publib.boulder.ibm.com/tividd/td/ITMAN/SC32-9195-00/en_US/HTML/sap_add06.htm

    Well using SQL trace
    like as follows:
    Goto transaction ST05. Press TRACE ON.
    Execute your transaction .
    Come back to this screen and click TRACE OFF.
    Then check the trace details.
    You end up getting unnecessary details
    Lets say you have to analyze your particular SQL query,
    1. put a breakpoint at the select statement and execute the transaction , as it stops at your breakpoint , run SQL trace in seperate session.
    2. Trace ON
    3. Execute the select statement.
    4. Trace OFF
    5. Analyze.
    In this way you can analyze your particular select query
    Pls check links like:

    SQL Trace
    SQL trace (ST05) provides the developer with the ability to analyze database select statements. Simply execute ST05 to turn on SQL trace, then execute the statement/program you want to analyze. Now turn off SQL trace using ST05
    And click on list trace to view the details.
    Authorization trace analysis
    1. Open two sessions
    2. Execute transaction ST01 in one of the sessions
    3. Select the authorization checkbox, note the other traces
    you can perform (SQL, RFC, Table Buffer etc)
    4. Click the 'Trace On' button
    5. Within your other session execute the transaction/report
    you want to trace or get the user in question to do it
    6. Return to the session where you turned the trace on and
    click on 'Trace Off' otherwise it will continue to record all authorization checks
    7. Click on the 'Analysis' button
    8. Enter appropriate data into selection screen such as
    Username, type of trace records (i.e. Authorization check)
    9. Click on the Execute button.
    10. Report displaying trace results will now be displayed

    when I've enabled sql trace event 10128 level 2,and i execution query then appears error
    ORA-00604: error occurred at recursive SQL level 1
    ORA-00942: table or view does not exist
    where the fault lies??
    i'm using
    ALTER SYSTEM SET timed_statistics=TRUE;
    ALTER SESSION SET EVENT '10128 TRACE NAME CONTEXT FOREVER, LEVEL 2';

    But nothing issue with me on 10g on windows xp:

    This is not "EVENT" .. it is "EVENTS"

  • Ask result sql trace events 10046 level 8 and 12

    hi all, i read result of sql trace events 10046 level 8 on
    http://www.oracle-base.com/articles/10g/SQLTrace10046TrcsessAndTkprof10g.php#trace_example
    and I do sql trace event 10046 level 8 or 12. But the results did not same, execution plan does not appear
    how to have execution plan appears??

    We use level 12 and we have both RSO (row source operation) and execution plan. Remember, execution plan is just the preditive estimate execution path by the opimizer. RSO is actually how the optimizer executes.

  • Ability to perform ALTER SESSION SET SQL TRACE but not all alter clauses

    I see that in order to run the ALTER SESSION SET SQL TRACE command, the user should be explicitly granted alter session privilege as the CREATE SESSION privilege alone is not enough. Is there a way to grant the ability to perform ALTER SESSION SET SQL TRACE but not the other clauses such as GUARD, PARALLEL & RESUMABLE?.
    Thanks
    Sathya

    If you are using Oracle 10g and above, you can use DBMS_SESSION.session_trace_enable procedure,
    it doesn't require alter session system privilege.
    Simple example:
    SQL> connect test/test@//192.168.1.2:1521/xe
    Connected.
    SQL> alter session set tracefile_identifier='my_id';
    Session altered.
    SQL> alter session set sql_trace = true
      2  ;
    alter session set sql_trace = true
    ERROR at line 1:
    ORA-01031: insufficient privileges

  • How to use the transaction STO5 (SQL Trace)

    Hi,
        I want to check the performance of program using the ST05 transaction. Please send me the step by step procedure to trace my program.
    Thanks & Regards,
    Santhosh Kumar.R

    Hi,
    following explanation clearly you abt ST05
    Hi,
    SQL trace(ST05) provides the developer with the ability to analyse database select statements. Simply execute ST05 to turn on SQL trace, then execute the statement/program you want to analyse. Now turn off SQL trace using ST05
    and click on list trace to view the details.
    You can also perform traces on other items such as authorisation objects.
    The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
    The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on the SPFLI table in our test program is mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
    The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
    To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
    Performance Tuning is useful mainly reducing load on database. It is very important aspect while writing the programs/FM etc.....
    SQL Trace
    Use
    The SQL Trace function is an on-demand log of selected SQL statements that are issued against the database through the Open SQL Engine. The SQL Trace can be switched on or off dynamically. The log format is database independent. Besides the SQL statement text, each log record contains information about the point in time when the statement was executed, its duration, its input parameters and results (where applicable) as well as context information.
    Features
    The SQL Trace is especially useful for:
    Development:
    SQL Trace can help JDO, enterprise beans, servlet and JSP developers to learn which kind of database accesses their code produces.
    &#61489;&#61486; Performance analysis
    Typically, performance issues are caused by inefficient database accesses. In this case SQL Trace can be used to show the issued SQL statements and their duration, thus helping to identify inefficient SQL statements.
    Functions
    <b>The following functions are available on the initial screen</b>:
    Select trace:
    • Select the trace mode SQL Trace, Enqueue Trace, RFC Trace, or Table Buffer Trace. You can select mutliple trace modes simultaneously.
    Select trace function:
    • Start the trace recording.
    • Stop the trace recording.
    • Branch to trace list, detailed list, or time-sorted list.
    • Branch to Explain SQL to analyze an SQL statement without an explicit trace file.
    Trace files are managed by the system. Thus they can be saved, like any other object;
    saved trace files can be displayed and deleted.
    Trace Status
    A trace can only be activated once on any application server. The Trace Status display informs you whether another user in the system has already activated a particular trace.
    Starting the Trace
    Prerequisites
    <b>You can only switch on the Performance Trace for a single instance</b>. You should already have decided the scope and targets of your performance analysis.
    Procedure
    <b>To analyze a trace file, do the following</b>:
    ... 1. Choose the menu path Test &#61614; Performance Trace in the ABAP Workbench.
    The initial screen of the test tool appears. In the lower part of the screen, the status of the Performance Trace is displayed. This provides you with information as to whether any of the Performance Traces are switched on and the users for which they are enabled. It also tells you which user has switched the trace on.
    2. Using the selection buttons provided, set which trace functions you wish to have switched on (SWL trace, enqueue trace, RFC trace, table buffer trace).
    3. If you want to switch on the trace under your user name, choose Trace on.
    If you want to pass on values for one or several filter criteria, choose Trace with Filter.
    Typical filter criteria are: the name of the user, transaction name, process name, and program name.
    4. Now run the program to be analyzed.
    You will normally analyze the performance trace file immediately. In this case, it is a good idea to use a separate session to start, stop, and analyze the Performance Trace
    If you are shown trace kernel errors on the initial screen (for example, not enough storage space available), you must first remove the errors or have them removed by your system administrator.
    The selected trace types can be changed as required during a performance trace interval (time between switching on and off the trace). The user (user group) must remain unchanged.
    Result
    The results of the trace recording are written to a trace file. If trace records are overwritten during the trace interval, the system displays a message to inform you when you analyze the trace file.
    The results of the trace recording are stored to ten trace files. Overwriting trace records, however, cannot be entirely excluded in this case either.
    The Performance Trace records all database access calls, table buffer calls, remote calls, or calls for user lock activity. These measurements can affect the performance of the application server where the trace is running. To preserve system performance, you should therefore turn off the trace as soon as you finish recording your application.
    Stopping the Trace
    Prerequisites
    You have started the trace and finished running the program that you want to analyze.
    <b>For performance reasons, you should switch off the traces as soon as you have finished recording.</b>
    Procedure
    <b>To deactivate the trace:</b>
    ... 1. Choose Test &#61614;Performance Trace in the ABAP Workbench.
    The initial screen of the test tool appears. It contains a status line displaying the traces that are active, the users for whom they are active, and the user who activated them.
    2. Select the trace functions that you want to switch off.
    3. Choose Deactivate Trace.
    If you started the trace yourself, you can now switch it off immediately. If the performance trace was started by a different user, a confirmation prompt appears before deactivation-
    Result
    The results of the trace are stored in one or more trace files. You can then analyze the performance data stored in the trace file. See also, Analyzing Performance Data.
