Remote Stored Procedure Call Dispatcher WEB WERVICE

Hello all,
Environment: Windows OS, Oracle 10g, mod_plsql
I am looking for solutions to the following problem:
A way to dispatch calls to stored procedures from client to server with a minimal impact on performance.
We are looking at two possible solutions:
1) Making a call to a Remote Stored Procedure Call Dispatcher (RSPCDispatcher) stored procedure through mod_plsql.
2) Making a call to a Remote Stored Procedure Call Dispatcher (RSPCDispatcher) stored procedure through a web service.
Solution 1) is not the preferred one as you may already know that mod_plsql will not be supported starting 12g.
Solution 2) is the one we prefer as we believe that web services will be ever more supported in the future. When we move to 11g we may turn this web service into a native one (avoiding overhead in the OC4J for hosting the web service etc.).
We are looking for code examples and information pointers of how we could implement this dispatcher as a stored procedure in a DB package. We know that the implementation should be similar to the one done for mod_plsql in the OWA schema but the code there is obfuscated, so we could not borrow ideas from there.
We are not sure how to deal with the generalization of the above stated problem. We need to be able to pass to this dispatcher the stored procedure package and name we are invoking, ordered list of parameters (or parameters map), and the transport strategy (XML, JSON, etc.).
Basically, we are notsure how to deal with the USING clause of the EXECUTE IMMEDIATE statement. We can dynamically generate the SQL statement corresponding to the stored procedure we want to call, but we are not sure how to bind the parameters we are passing?
Also, we know that EXECUTE IMMEDIATE may be slow sometimes. So if could avoid it, this could further improve performance.
Perhaps the run-time generalized stored procedure execution may not be what we are looking for?! Perhaps we should include several design-time steps?! What about a script that given a package name (or just a single stored procedure) would generate a wrapper package which stored procudures' names would correspond to their respective counterparts in the given package which would take two parameters - the list of parameters in some sort of format, and the transport (content delivery strategy) and would return the result in the given content delivery strategy?! This script may also define the XSD of the XML message a stored procedure is called with (the parameter map) as well as the XSD of the XML result the stored procedure returns. Also the script could generate client code with the given language strategy (Java, .NET, etc.) for calling the RSPCDispatcher web service.
We request the following from the Oracle community folks:
a) Please, give us any relevant information that could be helpful to resolve this problem.
b) Any resource of how to inspect stored procedures in a package, its parameters, parameter types and direction (IN, OUT, or INOUT), etc.
Thank you very much in advance.
Regards,
Georgi

Web Service receives no data from Stored Procedure call.

Issue: When calling a Stored Procedure from a Web Service no data is returned.
Lead up: I can call the SP 100 times a day for 3-4 days then for some reason the Web Service no longer get the data from SQL. I have ran a trace and I can see the SP running though all of its steps and returning the data, but the Web Service
is not getting it.
Fix: None yet.
Work around: Before the Web Service calls the SP, I am sending an SP_Recompile to the SP in question. For now this seems to have resolved the issue.
Detail:
1. SP is querying data from another DB on the same server.
2. SP is storing query data in Temp Tables.

Hello,
Does your Stored Procedure have parameters? If so, the issue may be cause by parameter sniffing. Please refer to the following blog about Paraemeter Sniffing:
http://www.sommarskog.se/query-plan-mysteries.html
The recommended fix for most situations is to not use parameters directly in queries, but rather store them into local variables and then use those variables in the queries.

Calling Remote Stored Procedure from Pocket PC

Hi all,
I have finished building an application based on IBM's SMF framework which conforms to the OSGI standards. Currently, I am having a problem with connecting to the main server DB which resides on a Websphere server. Basically, user will enter information on their pocket pc and then save it to a local DB2e database. I thought about going with the synchronization solution with the DB2 Sync server, but really all the user is trying to do is updating records in the main server database tables and there's really no need to sync anything back from the server to the pocket pc. So, I m thinking maybe I should try to invoke a stored procedure that resides on the main DB server from my device, passing in parameters through a WLAN connection.
My question now is:
1. user should be connecting through a WLAN connection and my company have set up a login that prompts the user to login everytime they try to access anything on the server. It won't be nice if the user will hv to do that every single time. Is there a way that I can log the user in programmatically so they do not have to do it with a separate log in window?
2. Is calling a remote stored procedure a bad idea?
3. If the network goes down, then there's no way the users can update anything to the main server DB. So, the changes will be saved locally and once the network goes back up, the user should be able to update those changes back to the server. I am just wondering if it's bad to do a loop and send those updates to the server by calling the stored procedures repeatedly passing in diff. parameters? what safeguards do I need to put in? like what exceptions should I expect to catch? also, I would like to be able to track those updates that failed, how do I do that?
Any help will be appreciated. I tried to find resources online, but to no avail. I am not sure if I am overly complicated things. Please advice! Thanks alot everyone!

WCF OData Service stored procedure call generates "Operation could destabilize the runtime" error with $select option

I've been trying to call a stored procedure through Entity Framework and WCF Data Services (OData). It returns an entity not a complex type. Following walkthroughs found all over the web, I came up with this code inside my service:
[WebGet]
public IQueryable<Entity> GetEntitiesByParameterId(int parameterId)
return CurrentDataSource.GetEntitiesByParameterId(parameterId).AsQueryable();
Calling the proc this way: ~WcfService.svc/GetEntitiesByParameterId?parameterId=1 executes
the stored procedure and returns entities that should be returned. No problem there.
Everything works well until I try to use $select OData option ie. ~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$select=name.
Upon debugging, the method above runs without any error but it returns an Operation could destabilize the runtime error upon reaching the
client. After so much research, apparently it is a very general error pointing to a lot of different causes. I haven't found one that really matches my particular problem. Closest are
http://stackoverflow.com/questions/378895/operation-could-destabilize-the-runtime
https://social.msdn.microsoft.com/Forums/en-US/d2fb4767-dc09-4879-a62a-5b2ce96c4465/for-some-columns-entity-properties-executestorequery-failed-with-error-operation-could?forum=adodotnetdataservices
but none of the solutions worked on my end.
Also, from the second article above:
This is a known limitation of WCF DS. ...
Second is that some of the queries won't work correctly because LINQ to EF needs little different LINQ expressions than LINQ to Objects in some cases. Which is the problem you're seeing.
It has been posted on 2012. If it its true, are there still no updates on this? And is there any other workaround to get the $select working on the stored proc call?
What works:
~WcfService.svc/GetEntitiesByParameterId?parameterId=1
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$top=1
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$skip-5
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$filter={filter query}
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$expand=SomeNavigationProperty
What doesn't work:
~WcfService.svc/GetEntitiesByParameterId?parameterId=1&$select=name
Tech details:
EntityFramework 5, WCF Data Service 5.0, OData V3
*I've also tried upgrading to EF6 and WCF 5.6.2 and it still didn't work.
Any help would be appreciated. Thanks!

Someone from SO replied to my question there and said that $select is still not supported though I couldn't find any definitive documentation about it.
From what I gather and observed, $select breaks the stored procedure call because it tries to alter the data shape already gotten from the database and attempts to return a dynamic entity instead. Something about the stored proc returning an ObjectResult might
be messing it up. As I have said, these are merely my observations.
Workaround: I found a simple and elegant workaround for it though. Since my stored procedures are only getting data from the database and does
not alter data in any way (INSERT, UPDATE, DELETE), I tried using table-valued functions that returns a table equivalent to the entity on my EF. I've found that calling this function on the Service Operation method returns an IQueryable<Entity> which
is basically what is needed. $select also works now and so does other OData query options.
Steps:
Create a function on the database
Update EDMX -> Add function
Add new Function Import with Entity return type
Create service operation in WCF Data Service that calls CurrentDataSource.<FunctionName>()
Test in fiddler.
CODES
Database Function:
CREATE FUNCTION GetEntities(@parameter)
RETURN @entites TABLE(
[Id] [int],
[Name] [nvarchar](100),
AS
BEGIN
INSERT INTO @entities
SELECT [Id], [Name], ... FROM [EntityTable]
RETURN
END
WCF:
[WebGet]
public IQueryable<Entity> GetEntity(int parameter)
return CurrentDataSource.GetEntity(parameter);
It doesn't really solve the stored procedure problem but I'm marking this as answer until someone can provide a better one as it does solve what I'm trying to do.
Hope this helps others too. :)

DML visibility in stored procedures called via JDBC

Hello,
I have two stored procedures, A and B. Proc A inserts Q into table X. Proc B selects Q from table X to insert it into table Y. Neither procedure does a COMMIT.
My Java class executes Proc A and then Proc B within a transaction (autocommit is false). But Proc B fails to select Q from table X with the No Data Found error, apparently unable to see the recently inserted Q.
If these two procedures are called from a SQL*Plus block, everything succeeds.
Does anyone have a clue about what I am missing? All my DML should be visible to my session.
Thank you in advance for any suggestions.
- CJ

Thank you, Joe, for your reply!
To the best of my knowledge, all of my stored procedure calls are being made from the same connection so I can rollback everything if necessary. I have not explicitly closed the connection between calls. The debugger indicates my connection session id never changes across calls.
Do you know of any JDBC trace tools that might help me verify my connections? I've enabled logging with oracle.jdbc.driver.OracleLog.setTrace(true) but it doesn't really give me specific connection information - at least not that I can tell. :)
Thanks!

Stored Procedure call from JDBC sender for Oracle Database

Hi,
I have a requirement to call stored procedure using JDBC sender adapter for retriving data from an Oracle database.
I need to execute first stored procedure call from Querry SQL statement and then trigger second stored procedure call for confirming the succesful retrival of those records from the update SQL statement.
Querries:
1. Can we trigger stored procedure from Update statement of JDBC sender.
2. Can we call stored procedure from Querry statement, since I have read on other sdn threads that stored procedure calls on Oracle database are not allowed. If not possible to have "Execute stored procedure" would the function call (select * from table(function name)) work same as stored procedure.
3. In a JDBC sender the Querry statement and Update statement are executed in same session call and same database connection. What happens if the querry statement was not succesful, would the update be still triggered.
Please note PI does not have direct access to main table and hence the need to have separate stored procedure calls.
The PI version is PI 7.11 sp4.
Appreciate your inputs.
Thanks.
Siddhesh S.Tawate

>1. Can we trigger stored procedure from Update statement of JDBC sender.
I think not possible using update statement.
> Can we call stored procedure from Querry statement, since I have read on other sdn threads that stored procedure calls on Oracle database are not allowed. If not possible to have "Execute stored procedure" would the function call (select * from table(function name)) work same as stored procedure.
Yes using select query you can call stored procedure.
>. In a JDBC sender the Querry statement and Update statement are executed in same session call and same database connection. What happens if the querry statement was not succesful, would the update be still triggered.
No select and update handles in the same session using the same thread so if one transaction fails update should not proceed.

Execution Times of Stored Procedures Called from Other Stored Procedures

If I execute sys.dm_exec_procedure_stats, it will produce execution times of my stored procedures executed recently.
However, stored procedures called from other stored procedures do not show up.
Is there code that can return the execution times of stored procedures even though they are called from other stored procedures.

Look at the example. It is counting nested execution.
CREATE PROC z1SP AS SELECT * FROM Production.Product;
GO
CREATE PROC z2SP AS SELECT * FROM Production.Product WHERE Color is not null; EXEC z1SP;
GO
SELECT object_name(2002822197), object_name(2034822311);
--z1SP z2SP
EXEC z1SP; EXEC z2SP;

Hi,
Check your DATA TYPE attributes with the attributes of the column names in the Database table. There is a mismatch between the DT and Table in the database.

Response from one stored proc. to another stored procedure call in JDBC

Hi,
I have to call 2 stored procedures, where the response from first stored procedure ( an id) is mapped as a parameter to the second stored procedure call.
My question is that can this be achieved without using BPM?
Can we somehow map the response from the stored procedure 1 to stored procedure 2 parameter w/o using BPM?
I have to insert multiple rows using the stored procedure.
Should I use STATEMENT unbounded times ( which means stored procedure is called multiple times) or should I use the parameter as unbounded ( like an array, maybe define the parameter as an array in the stored procedure)?
From the performance standpoint, which approach is better?
Please suggest.

Hi Ardent !
I think you could use 2 mapping programs (message mapping objects) in your interface mapping. The first one, executes and returns the ID to a message type defined by you for internal use only between both stored procedure executions. The second ones uses that message type as source message and the XML required by the JDBC for the second stored procedure execution as target message type. This can be done without BPM.

Matias.

Stored Procedure Call with only Input Parameter

You need to use a DataModifyQuery as your query does not return anything.

Stored Procedure call to Oracle - issue

hi ,
I am trying to call a receiver JDBC adapter to call an oracle stored procedure -
I got this error ->
java.sql.SQLException: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call - which I understand is related to mismatch btw the XML and Stored procedure
I checked the XMl and it matches the stored procedure call. I have two specific questions -
1) I have used SAP Note 801367 to have a look at the SQl command sent to the db.. However I do not see the stored procedure in the Audit logs...Does this feature work for Stored procedures too?
2) Can you look at the XML sent to the JDBC adapter...I saw something wierd... even though I had declared the isOutput attribute first and then attribute type... when I loaded the MT into the mapping the order changed...Does than matter?

Arvind,
Just to be sure: are all inputs to yourstored procedure of type varchar, or are there maybe inputs with different types?
A mismatch between the type specified in the XML and the expected inputs of the SP can also cause this error.

Koen

Stored procedure call returns null result set when using temp table in sp!

Here's a really odd problem...
SQL Server stored procedure called sp_Test takes 1 input INT. Here is the code I call it with
cStmt = connection.prepareCall("{call sp_Test(?)}");
cStmt.setInt(1, 44);
cStmt.execute();
rs = cStmt.getResultSet();When the body of the stored proc is
CREATE PROCEDURE sp_Test(@i_NodeID INT)
AS
BEGIN
SELECT node_id FROM tbl_NavTree
END
GOthe query works and I get all node_id back in rs
BUT when the body of the stored proc is
CREATE PROCEDURE sp_Test(@i_NodeID INT)
AS
BEGIN
CREATE TABLE #Descendants(
descendant_id INT
SELECT node_id FROM tbl_NavTree
DROP TABLE #Descendants
END
GOThe rs comes back as NULL. Really really weird if you ask me. I also tried removing the DROP TABLE line just in case the SELECT had to be the last statement but still NULL.
Final note is that BOTH the above stored proc bodies work when executed within SQL Server query analyser.
Must be JDBC .. what can it be!??

DROP TABLE #DescendantsMS SQL Server - right?
Then don't drop the table.
From the MS docs for "create table"
Local temporary tables are visible only in the current session;
A local temporary table created in a stored procedure is dropped automatically when the stored procedure completes. The table can be referenced by any nested stored procedures executed by the stored procedure that created the table. The table cannot be referenced by the process which called the stored procedure that created the table.

JDBC callableStatement stored procedure call cancellation?

up vote0down votefavorite
I have a very complex oracle stored procedure that searches and retrieves some data. The procedure returns an output parameter - an oracle cursor. I execute the procedure by JDBC:
CallableStatement stmt = conn.prepareCall("{call myprocedure(?,?,?,?}");
The problem is, the queries can sometimes take quite long (few minutes) and i would like user to be able to cancel the query anytime by clicking button. I have reference to stmt object, but unfortunatelly calling stmt.cancel() (from other thread) has NO EFFECT.
On the other hand when i change the CallableStatement sql to some query like:
CallableStatement stmt = conn.prepareCall("select * from all_objects");
i get "java.sql.SQLTimeoutException: ORA-01013: user requested cancel of current operation" after calling stmt.cancel() - so thats the right reaction.
Does that mean than i cannot cancel stored procedure call via jdbc, but only simple select statements? Does anyone else had and resolved similar problem?
I guess i could cancel the query by oracle kill session, but i use connection pooling (jboss) and i have plenty of sessions for the same user existing.
Database Product Version is Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production JDBC Driver Version is 11.2.0.4.0
any help will be appreciated.

This property didnt help, still no reaction after statement.cancel().
I could not cancel the statment from the db size , so i decided to spawn new java thread and run the statement in that thread, and when user clicks cancel button i just cancel the thread, some snipper of code below:
               AtomicBoolean userCanceled - this must be AtomicBoolean or volatile variable, so other threads would see the change of variable after clicking button
               try{
                MyCallableQuery callable = new MyCallableQuery(rs,stmt,this,rsh,outParameter);
                FutureTask<T> queryTask = new FutureTask<T>(callable);
                ExecutorService executor = Executors.newFixedThreadPool(1);
                executor.execute(queryTask);
                while (!queryTask.isDone()){         //stil processing statement
                 Thread.sleep(100);
                      if (userCanceled)){               //user decided to cancel
                       futureTask1.cancel(true);
                       executor.shutdown();
                       throw new SQLException("User decided to cancel procedure call");
                 result = futureTask1.get();
                 //here the code after the resultset has been processed without cancelation
               catch (SQLException e}{
               //here the code when user decided to cancel like clearing the datatable
and my callable class is like:
public class MyCallable<T> extends ProcRunner implements Callable<T> {
    private ResultSet rs;
    private CallableStatement stmt;
    private ProcRunner procRunner;
    private ResultSetHandler<T> rsh;
    private Integer outParameter;
    public MyCallable(ResultSet rs,CallableStatement stmt,ProcRunner procRunner,ResultSetHandler<T> rsh,Integer outParameter){
        this.rs = rs;
        this.stmt = stmt;
        this.procRunner = procRunner;
        this.rsh = rsh;
        this.outParameter = outParameter;
    @Override
    public T call() throws Exception {
       T result = null;
      stmt.executeUpdate();
       rs = (ResultSet) stmt.getObject(outParameter);
       rs = this.wrap(rs);
       result = rsh.handle(rs);
    return result;
