How to raise Workflow error from pl/sql procedure

Hi,
I have this OWB mapping that runs a PL/SQL procedure. The mapping is deployed to Workflow and OEM. The workflow is scheduled and run from OEM,
and I can watch its progress/completion in the Workflow Monitor. Occasionally, the PL/SQL hits a situation I want to flag as an error to OWF so
that the OWF standard error process can be activated.
How can I do that? I try to raise an exception from the proc by calling OWF's core API (WF_CORE.RAISE etc.), but nothing happens.
From Workflow monitor no errors are detected, and the workflow seems to complete normally.
Any clues?
Regards
Rolf

Rolf,
I am no workflow expert but it seems to me that you trying to build a workflow exception handler by using the engine APIs (WF_ENGINE). In particular, you could call the WF_ENGINE.ABORT_PROCESS API and set the status to exception. This can be called from an exception handler using the WF_ENGINE.HandleError API.
As far as I know, the WF_CORE API mentioned by you will simply return an exception to the caller, but this will not affect the process flow.
For more details, please take a look at the workflow documentation, in particular if you log into the metalink site (metalink.oracle.com), go to the document http://metalink.oracle.com/cgi-bin/cr/getfile_cr.cgi?282250 which is the user's guide and look under chapter 8 which deals with APIs.

Igor

Sending message from PL/SQL procedure to form

Hello Friends,
How can I send messages from PL/SQL procedure to Form ?
Ultimate target is catching progress of PL/SQL procedure from
form. I heard about DBMS_PIPe but not sure,.
Adi

Hello,
Yeah , I got the solution using DBMS_PIPE function,I
followed following steps.
1. Pipe is created. see below procedure.
create or replace procedure proc_testpipe as
     v_pipe_integer          integer;
     v_pipe_message          integer;
begin
     v_pipe_integer := DBMS_PIPE.Create_Pipe('adipipe');
     dbms_pipe.pack_message('Hello Adinath Kamode,Message
     from Pipe');
     v_pipe_message := dbms_Pipe.Send_message('adipipe');
     end;
end;
2. then I created one Function which will obtain message from
Pipe and
will return value to form.
create or replace function proc_callpipe return varchar2 as
v_msg          integer;
v_rem          integer;
v_message          varchar2(500);
begin
v_msg:=dbms_pipe.receive_message('adipipe');
dbms_pipe.unpack_message(v_message);
dbms_pipe.purge('adipipe');
v_rem := dbms_pipe.remove_pipe('adipipe');
return(v_message);
end;
3. Last I called this function from form.
Cheers .. !

How to raise an event from a program

Hi,
I am creating a workflow for HR, the person will request a basic pay change than, this will start the workflow. For this i am making a screen from where i need to triger the event for the workflow.
Does anybody has any idea? of how to raise an event from a program. or has anybody worked on a scenario like this
Khusro Habib

You can also use the FM SAP_WAPI_CREATE_EVENT which is a little newer I think. (I don't have access to a system today so that may not be the exact name of the FM but if you search SE37 under SAPWAPIEVENT* you should find it.
the parameters will be the event name, and the object key. The object key will be the key field of the workflow object you are using.
For example if you were using the saled document object then the object key would be the sales document number. Carefull how you enter the object key, it can be a little tricky on whether or not you need the leading zeros in the input parameter.
Hope this helps.

Returing array from PL/SQL procedure

Hi,
I am trying to return array from PL/SQL procedure. Heres is the code. I am getting an error "OracleParameter.ArrayBindSize is invalid ".
Will anybody let me know what is wrong in following code. or does anybody have code to return PL/SQL array using VB.NET.
oCommand.CommandText = "MyPack.TestVarchar2"
oCommand.CommandType = CommandType.StoredProcedure
Dim id As Integer = 10
Dim deptname As String()
Dim oParam1 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("id", Oracle.DataAccess.Client.OracleDbType.Int32)
Dim oParam2 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("deptname", Oracle.DataAccess.Client.OracleDbType.Varchar2)
oParam1.Direction = ParameterDirection.Input
oParam2.Direction = ParameterDirection.Output
oParam1.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.None
oParam2.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.PLSQLAssociativeArray
oParam1.Value = id
oParam2.Value = ""
oParam1.Size = 10
oParam2.Size = 20
oCommand.Parameters.Add(oParam1)
oCommand.Parameters.Add(oParam2)
oCommand.ExecuteNonQuery()
Thanks

Thanks Arnold for the reply..
Yes, I am trying to get result set in array which is unknow to me (No of rows return by the query). For the test I will pre-define the result set so that I will able to set ArrayBindSize.
I have read C# example but when I try to write it in VB.NET it gives me syntax error when I try to set the ArrayBindSize.
oParam.ArrayBindSize = new int[3]{15,23,13} // individual max size of 3 outputsWill you please let me know how to set ArrayBindSize (VB.NET) because I am new to this..
There is an example at otn "How to: Bind an Array to an ODP.NET Database Command" which does multiple INSERTs in one trip to database. This works fine. I need to do same for the SELECT statement which will return me multiple rows. I do not mean refCursor. If I use refCursor, it will make soft parse which I am trying to avoid using this Array techniq.
Thanks

Run report from PL/sql procedure

Send a report to report server from PL/SQL Procedure

Hi Report Gurus,
Please can I know how to run a report from pl/sql stored procedure. Is there any way to execute URL from PL/SQL?
Thanks,
Simi.

Why, yes there is!
If you're talking about PL/SQL stored in the database, check the function UTL_HTTP.REQUEST. A "describe utl_http" in SQL*Plus will do the trick.
But if you're talking about PL/SQL inside Forms, you can use WEB.SHOW_DOCUMENT instead.
Hope this helps,

Creating web service from pl/sql procedure

Hello.
I need to create a web service from pl/sql procedure and i chose JDeveloper for this implementation. I have wsdl, but I never created web services. So, I created web service with document/literal message format.
But I have several troubles:
1. All element names have lower case letters.
2. The SOAP envelope must begin from words soapenv:Envelope but i have soap:Envelope.
3. And operation name has tail like "Element".
I know bad way for implement 1 and 3 points. It's a modification of java_wsdl_mapping.xml and wsdl files. But if I want to add new method to my service all changes will be cleaned. It's not critical but inconvenient to support.
But for point 3 i have no ideas.
This task is very important for me. Can somebody help me?
JDeveloper 10.1.3.3

Aleksey

Hi, all:
Any idea of how to ftp a file within PL/SQL procedure? I have scheduled a job to periodically generate a file and want to ftp this file to another machine.
