Limit stored procedure (spruncalcaccount) to run on specific datasrcs

We are using the stored procedure spruncalcaccount to accumulate the P&L and then post the total to the Balance sheet. We then add up the Balance sheet and post an Out of Balance value if the BS is not zero.
This works perfectly but it takes a very long time to run. Further, it seems to apply the out of balance logic to all the datasources processed through spicdata IC_Match, Debit1, Debit2, Credit1, Credit2 members).
We therefore want to limit our posting by data sources.
We do not want to use an account property for the rollup. We also do not want to use rolltobs.
Is anyone aware of code that we can use to speed up the process? Any assistance would be much appreciated.

Hello,
   Did you try to use the instruction *XDIM_MAXMEMBERS ? You can add this for DataSrc dimension for example. This will create small queries which can run faster.
   You can have a look to the logic log files to see from where the big time is comming from. If you have big queries which take a lot of time, the *XDIM_MAXMEMBERS vvan help you.
Try something like
*XDIM_MAXMEMBERS DataSrc=2     to see if something is changing.

Stored Procedure Does Not Run Properly When Called From Portlet

We have a simple Java portlet that calls a PL/SQL stored procedure which we wrote. The stored procedure sends a large number of emails to users in our corporation using the "utl_smtp" package. The stored procedure returns a count of the emails back to the Java portlet when it's finished. This number is displayed in the portlet.
Our problem:
The stored procedure functions as expected when run from a PL/SQL block in SQL*Plus, and the Java portlet calls the procedure properly when sending out a smaller number of emails (Less than 200 usually). When we get into a higher number of emails the procedure hangs when called from the portlet, but it STILL functions properly from SQL*Plus. It does not return the number of emails sent
and the Java portlet is unable to return a SQLException. Also, we have noticed that emails are sent at a much slower pace from the stored procedure when it's called from the portlet.

Any Ideas?

Stored procedure fails when run from SSIS DataFlow task

I'hv a stored procedure (with dynamis SQL), taking colums names as parameters to run and returns dynamic columns in output. E.g. if I pass @ipselect = '*' it will returns all columns in output, when I pass @ipselect = 'column1, column2, column3'
,it will returns 3 columns in output.
Now I have SSIS package. I've Data Flow task in foreach loop container and it is taking parameter from client table. e.g
clientid       column name
1                        *
2                columns1,columns2,column3
3               columns1,columns2,column3,columns4,columns5,column6
4                       *
Foreach container loop through each client id and set ipselect parameter with
column name and that value is being passed to @ipselect stored procedure in Dataflow task. When there is @ipselect = '*' it runs fine ,returns all columns and write to destination. But when there is ipselect = 'columns1,columns2,column3',
it fails with below error:
[OLE DB Source [1]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E55.
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80040E55 Description: "Column does not exist.".
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC0202009. The component returned a failure code when the pipeline engine called PrimeOutput().
The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.
Any suggestion or solution would be really helpful.
Thanks!!

Hi Kevin,
Just an addition. To create SSIS package programmatically, please refer to the document:

How to limit the response rows while invoking a stored procedure from OSB 10gR3

Dear Experts,
I am trying to limit the response while invoking a stored procedure from OSB via DB adapter.
Here the stored procedure returns cursors as response. I tried using the MaxTransactionSize propertiy (which is used for polling the database option in DB adapter).
We are investigating the ways to protect the application from response containing huge number of rows.
Is there any way to restrict the number of rows returned in each and every cursor while invoking the stored procedure via DB adapter?
Thanks
Ram

Hi James ,
I want to know how to run stored procedure using jca adapter in OSB11g.
I am new to stored prcoedure,will be great if you could share some example on it as above.
Req: Single input xml will be posted on queue ,need to perform 3 DB operation (with same input):
1.Insert operation to insert master table contents.
2.select the primary key column value from master table for the last inserted record.
3.Need to insert primary key column value + other fields frm same xml file to child table.
Pls assist me on how to create a simple stored procedure and to run the same with OSB 11g.I am familiar with creation of DB adapter using Jdeveloper,we have option to perform insert and to call stored procedure here,will it be useful for this scenario?

Find out if a certain Stored Procedure runs

Hi all,
i have to state that i dont have much oracle specific database knowledge but i've spend half a day now gathering information about a certain problem and didnt find any really working solution.
What i want is to be able to find out if a certain stored procedure is currently running (executing) in the database. I need that to be able to prevent a user of my client application from executing a certain procedure more than once in the same time.
I have found some interesting information about the oracle Call Stack (dbms_utility.format_call_stack) but its not as helpfull as i orginaly thought because as far as i can see it only shows which procedures where executed (and are still executing) while the procedure with the dbms_output.put_line(dbms_utility.format_call_stack) command is executing.
But it doesnt show anything about procedures which are running in another instance of SQL*Plus, for example.
I have no other idea at the moment ...
So i hoped anybody in here maybe has an idea or maybe allready a solution.
But ... thanx in anyway =).
With greetings from germany,
Oliver Bankel

I'm sure there are several solutions.
This is how we solve this problem, not elegant but it works.
We have a table of procs that are running.
Active_Jobs
JOBNAME    VARCHAR2(35)
USERNAME   VARCHAR2(30)
STATUS     VARCHAR2(20)
Then within the proc
job_conflict               EXCEPTION;
BEGIN
select count(1) into v_status from ACTIVE_JOBS
where username = USER and status = 1 ;
if v_status > 1 then
   RAISE JOB_CONFLICT ;
end if;
INSERT INTO ACTIVE_JOBS (JOBNAME, USERNAME, STATUS)
   VALUES ('PROC NAME', USER, 1) ;
COMMIT;
DELETE FROM ACTIVE JOBS WHERE JOBNAME = 'PROC NAME' AND USERNAME = USER ;
COMMIT;
exception
   WHEN job_conflict THEN
     raise_application_error( -20010,'YOUR MESSAGE HERE');
END;

Run Authorware using an SQL stored procedure

I have an Authorware piece that reads a text file, performs
some calculations, generates a .bmp , writes an output text file,
and then closes. I would like to trigger this using an SQL Server
stored procedure. The piece works fine if it is run directly, but
the stored procedure does not run the Authorware program (though I
can run a variety of other applications using similar stored
procedures). Is it possible to call and run Authorware pieces from
other applications?
Thanks,
David

If I were to make a bet, I would say the issue is related to ODBC. Can you get access to you database using ADO directly? This removes two pieces: the ODBC drivers and the SQL Toolbox.

How to improve stored procedure performance?

hi,
Suppose I have a stored procedure which contains 30 insert/update statements. How do I know Stored Procedure is slowly running or don't have any performance issue? how to improve performance?
Thanks in advance.
Anujit Karmakar Sr. Software Engineer

Stored Procedures Optimization Tips
Use stored procedures instead of heavy-duty queries.
This can reduce network traffic, because your client will send to server only stored procedure name (perhaps with some parameters) instead of large heavy-duty queries text. Stored procedures can be used to enhance security and conceal underlying data objects
also. For example, you can give the users permission to execute the stored procedure to work with the restricted set of the columns and data.
Include the SET NOCOUNT ON statement into your stored procedures to stop the message indicating the number of rows affected by a Transact-SQL statement.
This can reduce network traffic, because your client will not receive the message indicating the number of rows affected by a Transact-SQL statement.
Call stored procedure using its fully qualified name.
The complete name of an object consists of four identifiers: the server name, database name, owner name, and object name. An object name that specifies all four parts is known as a fully qualified name. Using fully qualified names eliminates any confusion about
which stored procedure you want to run and can boost performance because SQL Server has a better chance to reuse the stored procedures execution plans if they were executed using fully qualified names.
Consider returning the integer value as an RETURN statement instead of an integer value as part of a recordset.
The RETURN statement exits unconditionally from a stored procedure, so the statements following RETURN are not executed. Though the RETURN statement is generally used for error checking, you can use this statement to return an integer value for any other reason.
Using RETURN statement can boost performance because SQL Server will not create a recordset.
Don't use the prefix "sp_" in the stored procedure name if you need to create a stored procedure to run in a database other than the master database.
The prefix "sp_" is used in the system stored procedures names. Microsoft does not recommend to use the prefix "sp_" in the user-created stored procedure name, because SQL Server always looks for a stored procedure beginning with "sp_"
in the following order: the master database, the stored procedure based on the fully qualified name provided, the stored procedure using dbo as the owner, if one is not specified. So, when you have the stored procedure with the prefix "sp_" in the
database other than master, the master database is always checked first, and if the user-created stored procedure has the same name as a system stored procedure, the user-created stored procedure will never be executed.
Use the sp_executesql stored procedure instead of the EXECUTE statement.
The sp_executesql stored procedure supports parameters. So, using the sp_executesql stored procedure instead of the EXECUTE statement improve readability of your code when there are many parameters are used. When you use the sp_executesql stored procedure to
executes a Transact-SQL statements that will be reused many times, the SQL Server query optimizer will reuse the execution plan it generates for the first execution when the change in parameter values to the statement is the only variation.
Use sp_executesql stored procedure instead of temporary stored procedures.
Microsoft recommends to use the temporary stored procedures when connecting to earlier versions of SQL Server that do not support the reuse of execution plans. Applications connecting to SQL Server 7.0 or SQL Server 2000 should use the sp_executesql system
stored procedure instead of temporary stored procedures to have a better chance to reuse the execution plans.
If you have a very large stored procedure, try to break down this stored procedure into several sub-procedures, and call them from a controlling stored procedure.
The stored procedure will be recompiled when any structural changes were made to a table or view referenced by the stored procedure (for example, ALTER TABLE statement), or when a large number of INSERTS, UPDATES or DELETES are made to a table referenced by
a stored procedure. So, if you break down a very large stored procedure into several sub-procedures, you get chance that only a single sub-procedure will be recompiled, but other sub-procedures will not.
Try to avoid using temporary tables inside your stored procedure.
Using temporary tables inside stored procedure reduces the chance to reuse the execution plan.
Try to avoid using DDL (Data Definition Language) statements inside your stored procedure.
Using DDL statements inside stored procedure reduces the chance to reuse the execution plan.
Add the WITH RECOMPILE option to the CREATE PROCEDURE statement if you know that your query will vary each time it is run from the stored procedure.
The WITH RECOMPILE option prevents reusing the stored procedure execution plan, so SQL Server does not cache a plan for this procedure and the procedure is recompiled at run time. Using the WITH RECOMPILE option can boost performance if your query will vary
each time it is run from the stored procedure because in this case the wrong execution plan will not be used.
Use SQL Server Profiler to determine which stored procedures has been recompiled too often.
To check the stored procedure has been recompiled, run SQL Server Profiler and choose to trace the event in the "Stored Procedures" category called "SP:Recompile". You can also trace the event "SP:StmtStarting" to see at what point
in the procedure it is being recompiled. When you identify these stored procedures, you can take some correction actions to reduce or eliminate the excessive recompilations.

How to output various file types from a stored procedure

Good morning, I would like to output to spreadsheet files like microsoft Excel, Lotus 123 or to a comma delimited text file from stored procedures. We run Oracle 8i and this report is accessed from an intranet site using stored procedures and the pl/sql web toolkit. The results would be more usefull in a spreadsheet format than web page(s). Can anyone give me a hint as to which process to follow to get the output. Thanks very much, Francois

Probably best to try the PL/SQL SQL forum:
http://forums.oracle.com/forums/forum.jsp?id=478021
Some quick and easy pointers:
* Take a look at the COM feature available from PL/SQL in 8i:
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/win.920/a95499/toc.htm
* Just write the file out as comma delimited using UTL_FILE and give it a file name of .csv. Quick scan on google gives this example:

Hi jschell ,
Firstly, I tried out with execute() and getMoreResults() to check if the statement is returning result set. - Its returning "null" only.
Secondly, I tried with following one by one :
1. Find a new jdbc driver
2. Write a different stored procedure.I am using DB2 Express edition - DB2 v9.7.0.0
I have the required jar files - i)db2jcc.jar ii) db2jcc_license_cu.jar
From these I found the available jdbc drivers as -
i) com.ibm.db2.jcc.DB2Driver
ii) COM.ibm.db2os390.sqlj.jdbc.DB2SQLJDriver
iii) com.ibm.db2.jcc.uw.DB2StoredProcDriver
I tried out my code by using each of these drivers, but still returning result set as null.
Moreover, I changed my stored procedure which has cursor returning result set. In this case also, result set is null.
Code snippet for this SP is -
30             Class.forName("com.ibm.db2.jcc.uw.DB2StoredProcDriver");
31             System.out.println("Class loaded....");
32             con = DriverManager.getConnection
33                 ("jdbc:db2://localhost:portno/dbName", "user", "password");
34             System.out.println("Connection established....");
35
36             proc_stmt = con.prepareCall("call javaSP()");
37
38             System.out.println("Called stored procedure....");
39
40             proc_stmt.execute();
41             //proc_stmt.executeUpdate();
42             //rs = proc_stmt.getResultSet();
43
44             System.out.println("Query executed....");
45
46             if ((proc_stmt.getMoreResults() == false) &&
47                     (proc_stmt.getUpdateCount() == -1)) {
48                 System.out.println("No more result sets");
49             }o/p is (for every mentioned above jdbc driver) :-
Class loaded....
Connection established....
Called stored procedure....
Query executed....
No more result sets..
The o/p is always "No more result sets"
What else can be tried out to retrieve the result set from stored procedure from Java application? And the most important, these same stored procedures are returning result sets on db2 server after calling them.
Thank you,
Manasi.N

Stored Procedure for updating dynamic columns in a table

I have a table with a lot of columns around 30ish
Now I want to create a stored procedure that will update a specific column to a new value.
I the @columname and @newvalue to be the parameters, and an addition @itemId for the WHERE clause so it will update that specific row/data only.
here's my Stored Procedure
USE [db]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[usp_UpdateData]
@itemID int,
@ColumnName varchar(50),
@newValue nvarchar(50)
AS
BEGIN
Update dbo.ProjectAllocation
Set @ColumnName = @newValue
Where itemID = @itemID END
When I pass the following
@ColumnName: UserName
@newValue: NewUserName
@itemID: 1
it doesnt update row with itemID = 1.
How can I do this?
----------------------- Sharepoint Newbie

Did you try my last post method. Its better to use parameterized approach.
Anyway, if you want to change your code,you may need to change as below.....
SET @sql = 'UPDATE dbo.table SET ' + @ColumnName + '=''' + @newValue + ''' WHERE [itemID] = ' + cast(@itemID as varchar(50));

Problem in calling Oracle stored procedure from Java.

I am trying to invoke the Oracle stored procedure from Java. The procedure does not take any parameters and does not return anything. If I call it from SQL prompt it is working perfectly. I am calling it in my program as follows.
callable_stmt=con.prepareCall("{call pkg_name.proc_name()}");
callable_stmt.execute();
The problem is the control-of-flow is getting strucked in the second line I wrote. It is not giving any error also.
Please clarify me what's wrong with my code?
Seenu.

And how long does the stored procedure take to run from your client machine when running it via sqlplus?

Stored Procedure Concurrency

I'm using Java to connect to a SQL Server 2000 database. I connect using the Driver Manager with Sun's odbc driver ( sun.jdbc.odbc.JdbcOdbcDriver ) or I can use the jdbc driver provided by Microsoft (com.microsoft.jdbc.sqlserver.SQLServerDriver)
The Java application makes 1 Connection.
Within the database there exists a stored procedure that updates 2 Tables. The tables have a fixed number of rows that get updated continuously by calls to this stored procedure.
The Java application has a thread pool of 15 threads that create 15 CallableStatements (1 per thread) using the same instance of the Connection object.
According the the Microsoft JDBC driver docs, 1 Connection with multiple calls to the Callable statements is how it's supposed to be done. The following is an excerpt from Microsoft's "SQL Server 2000 Driver for JDBC User�s Guide and Reference" (page 86) regarding Connection Managment:
Managing Connections
Connection management is important to application performance. Optimize your application by connecting once and using multiple statement objects, instead of performing multiple connections. Avoid connecting to a data source after establishing an initial connection.
This is precisely what I'm doing, but I do not know if the the stored procedures are be run concurrently, the documentation does not tell me.
So my question: What is happening inside SQL Server 2000?

The Java application has a thread pool of 15 threads
that create 15 CallableStatements (1 per thread)
using the same instance of the Connection object.I believe this is bad and you're just asking for trouble. Each thread should have its own Connection - Connections are not thread-safe.

Invoking "java myClass" using Runtime.Exec from a Java Stored Procedure

Hi All,
This is regarding the use of Runtime.getRunTime().exec, from a java programme (a Java Stored Procedure), to invoke another Java Class in command prompt.
I have read many threads here where people have been successuful in invoking OS calls, like any .exe file or batch file etc, from withing Java using the Runtime object.
Even i have tried a sample java programme from where i can invoke notepad.exe.
But i want to invoke another command prompt and run a java class, basically in this format:
{"cmd.exe","java myClass"}.
When i run my java programme (in command prompt), it doesnt invoke another command prompt...it just stays hanging.
When i run the java programme from my IDE, VisualCafe, it does open up a command prompt, but doesnt get the second command "java myCLass".
Infact on the title of the command prompt (the blue frame), shows the path of the java.exe of the Visual Cafe.
and anyway, it doesnt run my java class, that i have specified inside the programme.
Even if i try to run a JAR file, it still doesnt do anything.
(the JAR file other wise runs fine when i manually invoke it from the command prompt).
Well, my question is, actually i want to do this from a Java Stored Procedure inside oracle 8.1.7.
My feeling is, since the Java Stored Procedure wont be running from the command prompt (i will be actually invoking it through a Oracle trigger), it may be able to invoke the command prompt and run the java class i want. and that java class has to run with the SUn's Java, not Oracle JAva.
Does any one have any idea about it?
Has anyone ever invoked a java class or JAR file in command prompt from another Java Programme?
YOur help will be highly appreciated.
(P:S- Right now, my database is being upgraded, so i havent actually been able to create a Java Stored procedure and test it. But i have tested from a normal java programme running in command prompt and also from Visual Cafe).
Thanks in advance.

MySQL/j Stored procedure on Server Failure? is it a bug? workaround?

Hi all, with the release of SE 6 pending, I thought that this issue should be addressed. As I'm not sure if it's a bug or not, I decided to post in this forum to see if anybody has haad experience with it, has a workaround or any other information that could be usefull.
The issue:
MySQL v5.x offers stored procedures. the MySQL/j connector has the ability to call these procedures.
If you run the stored procedure localy through Java, the stored procedure executes perfectly.
Once deployed onto a server, and the stored procedures on the same server in a mysql database and "ALL PRIVILAGES" including "EXECUTE ROUTINE" are granted. The stored procedure fails to run.
The error returned by the mysql/j connector is this :
"Driver requires declaration of procedure to either contain a 'nbegin' or 'n' to follow argument declaration, or SELECT privilege on mysql.proc to parse column types."
Here is a link to a MySQL forum about the issue:
http://forums.mysql.com/read.php?98,67532,67532#msg-67532
So it appears that it is a java issue.
Is there a workaround?
Has anybody successfully been able to use Java with MySQL stored Procedures?? (Pretty sad if we havn't)
Any help on this topic would be greatly appreciated.
cheers!

Yes, I read through the threads, that is Why I cam here after posting back with MySQL trying all the suggeestions, I still can't find the thread from the MySQL/J developer, I did find the one from a MySQL developer though.
We can't actually change permissions oursevles with our currecnt Servlet host.
So they changed permissions for us:
We checked to see if we had permissions, All permissions are granted for the localhost.
currently not sure how to check them for the '%' assignment
Our host also tried to drop the procedurees and create them again with the invoker command, but this was also to no avail.
I was also sure that it was a MySQL issue, but was hoping someobody had another method of a workaround.
It seems to be something to do with Java wanting the metadata for registering output variables.
