Requirements for serving Web PLSQL stored procedures

Hi all,
Can someone tell me what I need to host Web based PLSQL stored procedures?
I was told by Oracle Corp that I only needed 9i but after looking through all the documentation and these message boards, I think I need 9iAS.
If I need 9iAS, do I also need 9i?
And if so, can they coexist on the same Sun Solaris box?
Any help would be greatly appreciated.
Thanks in advance
Aaron

You'll need both - the Application Server to serve the pages, and the database to store the PL/SQL code. Yes, the two can co-exist - as long as they are installed in separate directories.
Hope this helps,

Publish PLSQL stored procedure as web services

Is it true that PLSQL stored procedure can only be published as web services using JAVA?
I came across article that mention how to call other web services from within plsql, but not sure the vice versa.
So, please advise.
Thank you.

True..I've done it once using J-Developer.

Problem while calling webservice from a plsql stored procedure

Hi everybody,
I need to call a webservice from a plsql stored procedure.
I was following documentation published in the otn at the following link.
"http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html"
I am encountering the following error on my sql prompt-
SQL> exec dbms_output.put_line(time_service.get_local_time('94065'));
BEGIN dbms_output.put_line(time_service.get_local_time('94065')); END;
ERROR at line 1:

Kiran, were you able to solve this?
I am facing the same error.
Oracle Server is Unix and webservice is .NET.
I am able to connect to Java web service.

How to generate XML Publisher report from PLSQL Stored Procedure in APPS

Hi,
I have concurrent program of type PLSQL Stored procedure.I need to generate XML Publisher report from the same.I have changed the output of the concurrent program as "XML" but when I tried running it,the XML tags are not generated.Due to this I am unable to create the template.Its a urgent issue.
Please help me out .
Thanks in advance.
Kaveri

Hi Kaveri
Sadly there is nothing magic about that output field. The only program type that you can flip it to XML and then magically get XML is for Oracle Reports. For plsql you will need to recode the plsql to generate XML rather than text that you have now.
You have some options, best option first:
1. Move the sql to a data template - check the user guide and blog for help or
2. Use SQL XML or XMLGEN (not great for large datasets) or
3. Use dbms_output.put_line and write the XML file manually - not performant at all

How to call PLSQL Stored procedure in ADF?

Hi!
I am using adf for our development. We have existing stored packages and I want to use them. The problem is how can I call those PLSQL stored procedure in ADF.
Thanks in advance
alvin.

Hi,
a stored procedure is called by the business service. If e.g. your business service is ADF Business Components then you call a stored procedure from the Application Module's transaction. Call a PLSQL procedure using a prepared statement. Similar you call stored procedures from EJB or TopLink business services
For ADF Business Components see

How to determine the load on the oracle server within a stored procedure?

Hi,
I have a subset of commands in my stored procedure that I would like to execute them only if there is not significant load on the database sever.
What would be the best way to measure the amount of load on my database server within a stored procedure?
Thank you,
Alan

It is not that easy.
This stored procedure is called by a job that runs every hour. Half of the stored procedure code are mission critical and must run by any means necessary! The second half must run right after the 1st one and is nice to do.
If I assign a lower priority it makes the situation worst, because then the job might take 3-4 hours and the same jobs run on top of each other over and over.
I just oversimplified the situation, The point is I prefer not to run the less important PLSQL code rather than assigning lower priority and stretch it over timeline. These hourly jobs are not Oracle jobs and cannot run on top of each other. Last time this happened and I had to kill 12 sessions! (12 jobs in 12 hour)
Trust me, estimating the load on the database server is the only solution.
When I say load on the server I mean the load resulted from other oracle sessions on the same database server. This server is a single instance Oracle 10g Enterprise on Solaris. All I need is just accessing to some meaningful counters.
Any help would be appreciated,
Alan

Wrapped PLSQL Stored Procedure

Hi,
Referring to Oracle 9i Enterprise Edition.
PLSQL stored procedure that is wrapped, can it be unwrapped?
After it is wrapped, is the original source still store inside the database dictionary or somewhere hidden in the database?
Please advise.
Thanks.

PLSQL stored procedure that is wrapped, can it be unwrapped?The primary use for wrapping PL/SQL is for ISVs distributing programs. It's to prevent customers prying into commercially sensitive code. It is also applicable in other security situations. Consequenmtly it doesn't make sense that there would be a clear version hanging around in the distributed app. The presumption is that the person doing the wrapping retains the original unwrapped source.

Urgent: unable to call a plsql stored procedure with a struts data action

Hello ALL,
I'm trying to call a plsql stored procedure within a struts DataAction,
The scenario is:
When a user a click on a button, then it should call a specific stored procedure,,
I create struts data action a class to handle the event which is to call the procedure
Here is my code:
public class RequestAction extends DataForwardAction
public void onCall(DataActionContext ctx)
String amDef = "model.AppModule";
String config = "AppModuleLocal";
ApplicationModule am =
Configuration.createRootApplicationModule(amDef, config);
try{
AppModuleImpl myAm = (AppModuleImpl)am;
DBTransaction tr = (DBTransaction) myAm.getTransaction();
CallableStatement stmt = tr.createCallableStatement
("begin pkg_test.test; end;", DBTransaction.DEFAULT);
stmt.execute();
stmt.close();
tr.commit();
catch(Exception e){System.out.println(e.getMessage());}
Configuration.releaseRootApplicationModule(am,true);
but when I ran the application and click on the button, I got the following Exception:
04/07/08 00:45:50 ORA-06550: line 1, column 7:
PLS-00201: identifier 'PKG_TEST.TEST' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
It seems that the DBTransaction object unable to see the stored procedure,
Am I do something wrong or miss something???
I've checked the examples on the OTN HOW TO, and searched in the JDeveloper Forum but unable to find an answer,
Please anyone can help???
Thanks a lot
With Regards,
Hayat

Here's an example application that illustrates how to do this. I haven't had a chance to writeup a little paper to go with it yet, but will as soon as I have a chance.
http://otn.oracle.com/products/jdev/tips/muench/storedproc/CallStoredProc.zip
See the "callStoredProcedure" method in the application module in the Model project.
See the "callStoredProcedure" method binding in the binding container of the "CallStoredProcedure" data page.
Notice the name "event_callStoredProcedure" of the (Call Stored Procedure) button on the CallStoredProcedure.jsp page which triggers the declaratively invocation of the method.
You could also call the method from code in a custom data action.
The code example illustrates how to create your own JDBC prepared statement for invoking the stored procedure, and doing it in a way that is efficient by keeping the prepared statement around across invocations.

Calling PLSQL Stored Procedure From HTML Form Submit Button

Hi there,
I am having a little difficulty with calling a stored procedure using an html form button. Here is the code I have right now...
HTP.PRINT('<form action=ZWGKERCF.P_confdelete>');
HTP.PRINT('<input type=''submit'' value='' Yes '' onClick=''document.getElementById("mypopup").style.display="none"''>');
HTP.PRINT('</form></div>');Here is the issue - I need to find a way to pass variables to this stored procedure so it know what data to operate on. This stored procedure will delete data for a specific database record and I must pass three variables to this procedure to make it work.
Lets call them class_number, term, conf These three variables will be passed and the data will be deleted and the person will see a confirmation screen once the delete query has been executed.
So ideally I would want: ZWGKERCF.P_confdelete(class_number, term, conf) and then the stored procedure would handle the rest!
Seems pretty simple but I am not sure how to make this happen... My thoughts were:
Pass the data to this html form (the three fields I need) in hidden variables. Then somehow pass these using POST method to the procedure and read using GET?
Can someone clarify what the best way to do this is? I have a feeling its something small I am missing - but I would really like some expert insight :-)
Thanks so much in advance!
- Jeff

This stored procedure will delete data for a specific database record and I must pass three variables to this procedure to make it work. The browser generates a POST or a GET for that form action, that includes all the fields defined in that form. Let's say you define HTML text input fields name and surname for the form. The URL generated for that form's submission will be:
http://../ZWGKERCF.P_confdelete?name=value1&surname=value2The browser therefore submits the values of the form as part of the URL.
The web server receives this. It sees that the base URL (aka location) is serviced by Oracle's mod_plsql. It passes the URL to this module. This module builds a PL/SQL block and makes the call to Oracle. If we ignore the additional calls it makes (setting up an OWA environment for that Oracle session), this is how the call to Oracle basically looks like:
begin
ZWGKERCF.P_confdelete( name=> :value1, surname => :value2 );
end;Thus the PL/SQL web enabled procedure gets all the input fields from the HTML form, via its parameter signature. As you can define parameter values with defaults, you can support variable parameter calls. For example, let's say our procedure also have a birthDate parameter that is default null. The above call will still work (from a HTML form that does not have a date field). And so will the following URL and call that includes a birth date:
URL:
http://../ZWGKERCF.P_confdelete?name=value1&surname=value2&birthdate=2000/01/01
PL/SQL call:
begin
ZWGKERCF.P_confdelete( name=> :value1, surname => :value2, birthdate => :value3 );
end;There is also another call method you can use - the flexible 2 parameter interface. In this case the PL/SQL procedure name in the URL is suffixed with an exclamation mark. This instructs the mod_plsql module to put all input field names it received from the web browser into a string array. And put all the values for those fields in another string array. Then it calls your procedure with these arrays as input.
Your procedure therefore has a fixed parameter signature. Two parameters only. Both are string arrays.
The advantage of this method is that your procedure can dynamically deal with the web browser's input - any number of fields. The procedure's signature no longer needs to match the HTML form's signature.
You can also defined RESTful mod_plsql calls to PL/SQL. In which case the call format from the web browser looks different and is handled differently by mod_plsql.
All this (and more) is detailed in the Oracle manuals dealing with mod_plsql - have a search via http://tahiti.oracle.com (Oracle Documentation Portal) for the relevant manuals for the Oracle version you are using.
Alternatively, simply download and install Oracle Apex (Application Express). This is a web development and run-time framework and do all the complexities for you - including web state management, optimistic locking, security and so on.

Beans using plsql stored procedures

Hi all
My question is: has jdeveloper any graphic tool or asistant to make something like use stored procedures that return multiple rows ( ref cursor ).
This is my problem, i'm student and have to build a web project that use beans, stored procedures and webservice.... i'm total noob in ejb, but i had worked with plsql some time.
Can anyone tell me pls where to start, some article to read or something that may help me in this task
Victor

A Ref Cursor doesn't have any implicit structure, so it's not easy to automatically bind bean to it, however if you create database types like this, for example:
drop type dept_t_list;
drop type dept_t;
drop type emp_t_list;
drop type emp_t;
create type emp_t as object(
empno number(4),
ename varchar2(10),
job varchar2(9),
mgr number(4),
hiredate date,
sal number(7,2),
comm number(7,2),
deptno number(2),
terminated varchar(1)
create type emp_t_list as table of emp_t;
create type dept_t as object(
deptno number(2),
dname varchar2(14),
loc varchar2(13),
emps emp_t_list
create type dept_t_list as table of dept_t;
/Then you can create a pl/sql store procedure that works with this types and list types easily as beans and arrays of beans using the JPublisher tool.
If you visit my Not Yet Documented Examples page and see example 36, it contains the SQL scripts that create example types and a stored package to work with them. It also contains the JPublisher-created Java classes for working with those types and package.
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
Inside JDeveloper, if you visit the connection navigator, expand your database connection and expand the "Packages" node, you can right-mouse and generate java (using JPublisher under the covers for you) on any package.

SOAP Fault when returning null from a Native Web Service Stored Procedure

I have a stored procedure which I can successfully invoke via soapUI
However, if one of the Stored Procedure's OUT arguments is set to null the native web service returns the following fault :
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Client</faultcode>
<faultstring>Error processing input</faultstring>
<detail>
<OracleErrors xmlns="http://xmlns.oracle.com/orawsv/faults">
<OracleError>
<ErrorNumber>ORA-19202</ErrorNumber>
<Message>Error occurred in XML processing</Message>
</OracleError>
<OracleError>
<ErrorNumber>ORA-01405</ErrorNumber>
<Message>fetched column value is NULL</Message>
</OracleError>
</OracleErrors>
</detail>
</soap:Fault>
</soap:Body>
</soap:Envelope>I can see how to control the processing of null values when invoking orawsv (using the null_handling element).
Is there an equivalent for Stored Procedures ?
Thanks,
PD
versions as follows :
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
"CORE 11.2.0.1.0 Production"
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

Without going into any technical discussion about the code, my first question is what JDK version was used to create this which was imported into the form? Understand that Forms 10 runs on JDK 1.4.2, so if you used any newer JDK version, likely there will be problems.

JDBC SQL Server Channel Calling Stored Procedure Won't Return Result Set

Good afternoon, Experts
We're calling a stored procedure in a sender communcation channel. I can perform any SQL SELECT statement here, but for some reason when I execute the SP (EXECUTE StoredProcedureName) The Adapter Engine returns the following:
Database-level error reported by JDBC driver while executing statement 'DECLARE @UpdateRecords bit SET @UpdateRecords = 0 EXECUTE ExportToSAP @UpdateRecords'. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor.
Even stranger yet is is that this works just fine on our PI-DEV system. I created an identical communication channel connecting to the same database with the same UID and PWD and it won't work in PI-QAS.
Any help/ideas you could share would be greatly appreciated!!!
Thanks,
Chad

Hi Chad.
Normally, itu2019s a problem with your procedure. The Store Procedure is wrong and something is different between your DEV environment and QAS environment.
Try to ask to DB team check it.

Switching Data Source for a report with stored procedure

Post Author: ysbn
CA Forum: Data Connectivity and SQL
I've created a report and deployed it on a Crystal Server. The report is based on a certain stored procedure which also exists on other DB machines in my environment (Oracle machines). When I try to switch my report object to work with other machines (not the one originally used when the report was designed) the activation of the report fails. The error I see in the preview window is:
Error in File <my rpt file name>: Failed to retrieve data from the database. Details: [Database Vendor Code: 6550 ]
When I try the same thing with a report which is based on a view and not a stored procedure the switching of Data Source works perfectly.
Is there a problem switching between data sources from the server when the report is based on stored procedure? Are there any configurations I need to do in order to support this scenario?
Thanks!

Hi everyone~
i am now facing the same problem
i am using CR2008 and Visual Studio 2008 c# to write a window program
because we have 2 db environment (one is production , the other one is development) so i have set a prarameter to switch db connection in c# code.
the database is Oracle, and the the report will connect to Oracle procedure (which it is stored in package) this procedure will return reference cursor, so the report will loop up this cursor to generate report.
at first time, it work fine when i open the report in CR2008 designer and point to dev database (ie datasource point to oracle procedure) . but when i want to deploy this win application to client and point to prod database, it show (vendor error 6550)
i found that i cannot change the datasource during runtime in c# code...
am i miss something in code? here attached a part of this code...
private void setDBLogonForReport(ConnectionInfo info, ReportDocument doc)
            Tables myTables = doc.Database.Tables;
            foreach (Table myTable in myTables)
                TableLogOnInfo logOnInfo = myTable.LogOnInfo;
                logOnInfo.ConnectionInfo = info;
                logOnInfo.TableName = myTable.Name;
                myTable.ApplyLogOnInfo(logOnInfo);
                //myTable.Location = info.UserID + "." + "pkg_crystal_report." + myTable.Name;
                //someone suggest i have to set the 'Location' for change the datasource, but i am not sure how to construct a
                //string for point to oracle prcedure
i will check it freq ... hope any expert can give me some advice ~
thank you very much!!!
