Database Adapter

Hi All,
My requirement is, based on the input selection from the frontend we have to query the database and then display the records based on the input. Sometimes we may have to display all the records from database. So I am using a DB Adapter in a SOA Composite and using Select operation. we have SQL query written in that Select operation. Initially the service was working fine because the number of records were very few. So it was fetching the records from the table and then we are able to display in the UI as well. Now the problem is we have more number of records in that table (more than 10000). So SOA Composite takes a lot of time to execute. Thats why we couldnt display all these records in our frontend. Can anyone help on this.
Thanks,
Maanik.

Hello Maanik,
I am not familiar with the DB Adapter but I would not assume that you want to display 10000+ records?
First you may need to check where the majority of the time is spent, in the database or in the network getting the data to your application. Testing the query can be done through SQL*PLUS where the command 'set timing on'. But with a 10000 rows, I would not immediately expect the database to be the culprit.
You may also want to consider to use an optimizer hint [url http://download.oracle.com/docs/cd/B10501_01/server.920/a96533/hintsref.htm#4942]FIRST_ROWS in your query. This will speed up the execution of the first few rows in your data set. Should you application display the information in subsets, this hint will be useful as the database returns the rest of the rows while the using is viewing the first rows through the application.
Thanks,
EJ

Logical delete in database adapter

Hello
I was wondering if someone has solution the problem with polling database. You can specify the logical delete column and you can give values for READ, UNREAD and RESERVED states. The problem is that when for example ESB project polls some specific table and starts an instance for every new row with specified logical delete field with value UNREAD, when something unexpected happens and something goes wrong the database adapter updates the row with READ value. This is problematic if we have thousands of rows, and we would like to separate the errored rows from the successfully read rows. Is there anyway (easy) way to update those rows that went wrong to some other value than READ?
I don't know if anyone understood me, but just for clarification here's a example:
I have a ESB-project which poll specific database table and parses and XML from the data. After this the ESB-project sends the data to some Web Service. The database table has column CONDITION_CODE in which value 0 means unread and value 1 means read. Now if everything goes fine there is no problems. But if the Web Service is unavailable or the data is malformed, the database adapter still updates the CONDITION_CODE to 1! We have no ways (except to listen ESB_ERROR topic and implement some error handling there) to know what rows were successfully delivered and which were not...
Hope I was able to clarify the problem... And I hope someone could be able to provide me with answer.
Best Regards Tuomas

Did you use the RESERVED value property? How about the transaction mechanism? Do you have global transactions? I gues you would have to use them!

Null/Empty Strings use in ESB Database Adapter

Hi
I'm trying to use a database adapter to execute an update on a table with a composite primary key; one of the primary key columns sometimes contains an empty string, however whenever I try to call the adapter, it always converts this to a null value. Is there an easy way to force the adapter to use an empty string instead of a null?
Thanks.

the idea here is to execute the dbms statement, or the setpolicycontext statement in a db session, and being able to execute the next sql statement in the same db session.
This is possible with consecutive database adapters sharing the same db session.
and two db adapters sharing the same db session is possible, if you make sure that the bpel is participating in the db transaction which can be made possible via xa db connections.
Hope this helps,

11g Database Adapter: How to make queries using LIKE with % (possible bug?)

Hi there!
Sorry if this has been answered before, but the forum search ignores '%' so I could not find anything relevant. I'm completely at a loss here guys so any help will be really appreciated.
I've got a database adapter that executes a "pure SQL" query:
select * from supplier t
WHERE t.idsupplier = #idSupplierParam OR #idSupplierParam2 IS NULL
AND t.name like '%' || #nameParam || '%' OR #nameParam2 IS NULL
AND t.address like '%' || #addressParam || '%' OR #addressParam2 IS NULL
AND t.description like '%' || #descParam || '%' OR #descParam2 IS NULL
I've got a single record in my DB with name= 'supplier1'
When I execute my bpel passing 'sup' as nameParam and nameParam2, everything is right and I get my supplier1 in the results.
BUT if I pass 'asdfghj' as name, I still get my 'supplier1' in the results ¿¿¿???
¿Is this a bug? ¿Am I doing something wrong? Thanks in advance!!

No, but thanks for trying. Iif you had read my post you'd had found that I wrote
+When I execute my bpel passing 'sup' as nameParam and nameParam2+
But I double checked against that just in case. I made a test query
select * from supplier t WHERE t.name like '%' || #nameParam || '%'
And no matter what I pass as nameParam, I always GET ALL THE RECORDS in my table. ¿Any idea what's going on? It's like param is being ignored and the query that is executed is select * from supplier t WHERE t.name like '%%' which would of course return everything in the DB. :(
Help plz!!

Use of current time for polling Database Adapter query

I am writing a simple BPEL process with a Polling Database Adapter and a Recieve. The idea is that we are polling an XE database for any entries in a TRIP table which have an expiration date/time field that has passed.
The Adapter was build using JDeveloper 10.1.3.2 (with Oracle Application Server patched to 10.1.3.3.0) as a "Poll for New Changed Records in a Table" Operation type with a STATUS field (0 for live, 1 for expired) as the Logical Delete Field.
I was unable to find a way to generate a SELECT query expression with the wizard that would allow me to use current/system time as an attribute, so I finished the wizard and edited the Toplink Descriptor to use a custom SQL expression for the query. This resulted in the following code in the toplink_mappings.xml file:

To test I used the above custom SQL at the command line and it filtered the records by EXPIRY_TIME as expected.
When deployed, the polling process updates the STATUS file dof table entries, but all entries with status 0 regardless of EXPIRY_DATE. My modification appears to be being ignored. I was unsure as to whether the QUERY was being determined in some other way so I modified the descriptor (with the toplink expression editor) to compare against a literal time value, producing the following modified toplink_mappings.xml:

On deployment, this version of the BPEL process behaved as expected - only modifying the records with EXPIRY_TIME less thatn the literal time specified. (Also, I can't really pass in the time as a parameter as this is a polling model).
Can anyone shed any light on what is happening or suggest how I might go about polling in the desired way?
Cheers

Please take a look at this article which states SYSDATE is not supported in a
where clause.
http://www.oracle.com/technology/pub/articles/bpel_cookbook/qualcomm-bpel.html
Excerpt from the article:
Here are three important things you should do in implementing the above design:
Have the status of the record being processed stored in the database. The status includes the process state, next process attempt time, and processing attempt count.
Create an updatable view that exposes only records that are ready to be processed. A view is needed because the database adapter cannot handle a where clause that compares against SYSDATE.
Design logic that determines if a process instance that has faulted should be retried and when the retry should occur. This information will be updated in the database by use of a stored procedure. This can also be done with an update partner link and additional logic in BPEL.

How to delete the content of a datatable by the "Database Adapter"

Hello,
i want to delete all entries in a table by a database adapter - like "DELETE FROM table" in SQL. (Oracle SOA Suite 11g SR1, with Oracle DB over JDBC))
When i create a new Database adapter i can select standard functions for "insert, select, delete". The function delete does have the disadvantage, that it needs a input message with the key values of the data entry which have to be deleted, which i don't have and don't want to get.
So i tried the "Pure SQL" mode for the adapter with the SQL string "DELETE FROM table" but this instruction is somehow not commited to the database.
My questions are:
- Is there any commit needed for the pure sql instructions? How is the syntax to write several SQL instructions for one Database Adapter?
- Does anyone have another solution to delete the entries?
Thanx in advance
Tobias

Hi Shishir,
it is a pretty simple example. I think the problem is that the Database Adapter is not commiting.
The BPEL is simple sending an empty message to the adapter which should trigger the SQL execution (See Code below)
The PURE SQL String i'm using is "DELETE FROM table"
Thanks Tobias

How to use Database adapter as inbound adapter without having polling strategies?

Hi All,
I have a requirement wherein I have to use Database adapter to retrieve the data for every half an hour from one(X app) database and update that data into another application(Y app) .That database adapter will be along with BPEL process.My Flow would be like this:
Database Adapter( In 'exposed services' section) ----->   BPEL (in 'Components') -----> Y app service( in 'External References' section)
My questions for each step are below
     1) I have to retrieve the data from database(x app database) for every half an hour.So I have to schedule my whole process such that it should execute for every half an hour.
Means I have to get whatever the data is updated in the last half an hour in that database.
      The database adapter should be inbound in SOA composite editor(in 'Exposed services' section).
But in order to have inbound adapter,we have select the 'Poll for New or Changed Records in a Table' option in turn we have to select one of polling operations below:
         Delete the Row(s) that were Read
Update a Field in the [Table_Name] Table (Logical Delete)
Update a Sequencing Table
Update an External Sequencing Table on a Different Database
Control Table Strategy
But the problem is I don't have any control on the database(X app database) ,So (I can't update any data on that table,because that table may not have a field or table to update the processed rows)I can't choose any of the above operations.
How can I achieve what I want that is to retrieve the data and schedule the process?
Thanks in advance.

Hi Heckler,
Thank you very much for your answer that I can proceed further somehow.
I still need to have some clarifications.
In order to have a process which retrieves the data (Inbound operation) and updates the data into other application, the data(from X app) should be the request(through DB adapter) of the BPEL process.
X app does not do anything to send.We have(the BPEL process) to receive the data (or) no event is triggered.
The flow :
Database Adapter( In 'exposed services' section to retrieve data) ----->   BPEL (in 'Components') -----> Y app service( in 'External References' section)
How can we ensure the data will be request to BPEL process(means it will be in 'exposed services' section in SOA composite editor) for every half an hour if we use pick activity and database adapter as first activity?
When we use ''Poll for New or Changed Records in a Table' ,then only adapter becomes inbound and comes into the 'exposed services' section.I can't use it as I don't have any control on the source table.
I have this confusion before starting the process.Please help me to clear out the doubts.
And this whole process should be executed automaticallly for every half an hour(means it creates instance for every half an hour) Once we build the BPEL process.
How to schedule it?
And where do I need to create control table ?You mean I have to use some different database where in I have to create the table?

How to use Database Adapter in BPEL

I want to use Database Adapter in BPEL to transfer data from one table to other table and the data is still hold in the read table?
I can find a example from http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28994/adptr_db.htm#BDCIGDCB.
And the general design of my BPEL is as following:
1. Add a "status" column to the read table. And alter the value of status column of all data in read table to "unreaded".
2. Then create a empty BPEL (BPELAdapter) Project.
3. Add a Database Adapter:
(1) In step 1 of Adapter Configuration Wizard, configure the Service Name to datain.
(2) In step 2, configure the database connection.
(3) In step 3, choose "Poll for New or Changed Records in a Table".
(4) Then click Import Tables button, and choose the read table.
(5) In step 5, choose a column.
(6) Don’t do anything in step 6 and 7.
(7) In step 8, choose "Update a Field in the [Datain] Table (Logical Delete)".
(8) In step 9, configure Logical Delete Field to STATUS, configure Read Value to readed and configure Unread Value to unreaded.
(9) Don’t do anything in step 10 and 11.
4. Add a receive activity to connect to above database adapter.
5. Add another Database Adapter. Then configure this database adapter service WSDL:
(1) In step 1 of Adapter Configuration Wizard, configure the Service Name to dataout.
(2) In step 2, configure the database connection.
(3) In step 3, choose Perform an Operation on a Table (and all items under it).
(4) Then click Import Tables button, and choose the write table.
(5) In step 5, choose a column.
(6) Don’t do anything in step 6, 7 and 8.
6. Add a invoke activity to connect to above database adapter.
7. Add a assign activity between the receive activity and invoke activity. And configure the assign copy operation.
But after I deploy this BPEL project to the BPEL server and invoke this project, I get following error. Meanwhile, this BPEL don't take effect.
The following exception occured while processing this request:

Now, I can insert data into the table through Database Adapter.
But still can't select data from the table through Database Adapter.
Above error still happen when invoke the read database table with Database Adapter project:
Can't find partnerLinkType 2.

Error while invoking custom API using Database Adapter

Hi,
I've a requirement where in I need to fetch the data returned by a recordtype of a custom API. I've implemented this by invoking the custom API using Database Adapter. I'm facing a problem while performing this.
The custom API holds the signature as:
PROCEDURE EMP_DET
Argument Name Type      In/Out Default?
P_DEPTNO NUMBER IN
L_LINE_TBL TABLE OF RECORD OUT
I've a schema with which it needs to be validated. It looks like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:po="http://www.mycompany.com/ns/sales" targetNamespace="http://www.mycompany.com/ns/sales" elementFormDefault="qualified">
<element name="EmployeeDetails">
<complexType>
<sequence>
<element name="EmpNo" type="integer"/>                    <element name="EName" type="string"/>                    <element name="Job" type="string"/>                    <element name="Mgr" type="integer"/>                    <element name="HireDate" type="date"/>                    <element name="Sal" type="decimal"/>                    <element name="Comm" type="decimal"/>               </sequence>
</complexType>
</element>
</schema>
I did a transformation to the above stated Emp.xsd with the xsd created for my custom API by the BPEL process. I could create the process and deploy successfully, but while invoking I get the following error. (I'm using BPM 10.1.3.1 with JDev 10.1.3.1)

Issue with DB Adapter - ORABPEL-11811

Problems while compiling a project that uses Database Adapter

Hi,
I am working on a small WebService that uses the Database Adapter to connect with the Oracle-Lite database. The process is a synchronous process which has client and DatabaseService as the partner link. The goal of this project is to get two inputs from the user and send it over to the DatabaseService for it to select the rows from the table based on the inputs sent. The process activity has an invoke function which had two varibles Invoke_1_inputVarible and Invoke_1_outputVarible. I have included the *.xds that contains the database schema. When I compile the project i get the following error
Error(38): [Error ORABPEL-10035]: wrong messageType [Description]: in line 38 of "D:\OraBPELPM_2\integration\jdev\jdev\mywork\Workspace1\Login\Login.bpel", messageType "{http://xmlns.oracle.com/pcbpel/adapter/db/ds/}EmployeeRole_msg" of variable "Invoke_1_dsSelect_InputVariable" does not match the expected messageType "{http://xmlns.oracle.com/pcbpel/adapter/db/ds/}dsSelect_inparameters" in <invoke>. [Potential fix]: make sure the correct variable is used in invoke.
My question is how do I assign correct messageType for the variables.

Error retrieving record through database adapter. (ORABPEL-11614)

Am trying to pass a customer name into a database adapter to retrieve customer info. It is working, but it is also faulting.

</summary ...
The retrieved data is correct. The Database Adapter is pointing to an AS/400 table which does not have primary keys defined. In the offline database, I've defined CGVMSTCST to be the primary key.
The toplink_mappings.xml reflects that:
<opm:alias>Cstcgvmp</opm:alias>
<opm:primary-key>
<opm:field table="CSTCGVMP" name="CGVMSTCST" xsi:type="opm:column"/>
</opm:primary-key>
The value of this field for 3M is 101 (which was correctly picked up).
Why am I getting a primary key is null error?

I did, but I'm not sure how.
I deleted the Database Adapter and the associated offline file and reran the wizard (having a better idea of how to implement a parameter search) and it worked.
I was not able to identify what was created differently the second time.

DataBase Adapter Issue

Hi all,
When i try to query the table using the Database adapter , i m getting the following error message
*" ORA-04030 : out of process memory when trying to allocate 2024 bytes( kxs-heap-c,kghsstk)* "
Experts please post the possible resolution for this issue..
Thanks in Advance,
Karthik

Hi-
Is the Database and Weblogic installed on same machine ??
When you execute queries from SQL worksheet this is the only program that is consuming memory..
But when you run from DB Adapter both your adapter and database consumes the memory and datbase is not able to get the required memory to run the script..
I am not quite sure of the issue, u can check the task manager and find it out when executing the program

List of values from Database Adapter - BPM Forms

Hi all,
Can anyone tell me how to get list of values from Database adapter and a ServiceTask.
As example lets say a table has Employee and Department columns.
I want to list down all the Employees in BPM form (Select One List Box) once i provide the department to the Database Adapter.
Is it possible from the DB Adapter?? What will be the variable type?
Thanks,
Nir

Hi DanielAtwood,
Thanks for your reply...
Actually when i send the variable in 'WHERE Clause' in Db Adapter query it will retrieve more than one record as the output.
I want to put that values to a 'SelectOneChoice' component and list down all the values..
First I tried with data control. But i couldn't find the way to pass the value to the variable(in WHERE clause) to the query in data control view.
Thanks,
Nir

The INSERT operation works fine with the database adapter, but I cannot get MERGE and UPDATE operations to work as expected!
Thanks.

hi Sudeep,
We are at first hand struggling with DB adapter problem getting down everytime. Don't know the reason why.
DB adapter is in down state and when trying to make it up gives below error:
"weblogic.application.ModuleException: weblogic.connector.exception.RAException: Jndi Name is null or empty."
I just created a simple sync process using DB adapter (custom select) and deplyed successfully. I hope jndi name is not to be configured in weblogic-ra.xml file.
This is the first time we are using this JNDI name (eis/DB/calvindb).
Any inputs will be appreciated.
Thanks,
Nikhil

How to include a response element in the ESB database adapter.

hi,
i am using the dbadapter to insert the data into the table successfully.
The problem is when i am using a db adapter it doesnot include a response element in its wsdl.I want to send a response to the client as and when the data got inserted from the dbadapter for that transaction.
i tried using the pl/sql procedure with a out parameter which returns the response but the problem is the pl/sql is called by adapter only once though i am using for each constructor.
i tried to modify the xsd generated by the dbadapter by including the response element,but the xsd is not getting parsed and throwing error.
how to overcome this problem and send a immediate response to the client as and when the adapter inserts the data into oracle?
thanks in advance.

Although not the cleanest solution, but can't you create another routing service which defines a request (equal to the request element of the original routing service) and reply element (defining a single element called success or something).
Then have this new routing service invoke your original routing service which invokes the database adapter. Now define a XSLT map for the reply of the new routing service and put an XSL text there with the value "success" or something?
So:
Routing_service_new --> Routing_service_original --> database_adapter

Using Variables in a select statement through a Database Adapter

I was wondering how I reference a variable in a select statement through a Database Adapter.
Ex.
1. I have a global variable that stores an employee number
2. I want to select an SSN # from a table based on an employee #
variable.
select ssn from emp where ssn = :input_variable - ????
- how do i reference the variable - I am getting a 'missing IN or OUT parameter error?
Any advice is much appreciated.
~Thanks

I'm just wondering if anyone knows a work around so that I might be able to store a Table's FIELD name in a variable or an array[] so that I can do a query based on the decision of a loop without having to code 10 IF/ELSE statements.For instance, although the above code will not work, this code, although quite lengthy, does:
If DataGrid1.SelStartCol = 0 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES__PUR_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 1 Then
Adodc1.RecordSource = "Select * from tblReservation order by VENDOR"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 2 Then
Adodc1.RecordSource = "Select * from tblReservation order by VEN_LOC"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 3 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_TYPE"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 4 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_FROM_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 5 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_TO_DT"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 6 Then
Adodc1.RecordSource = "Select * from tblReservation order by MISC_ADJ"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 7 Then
Adodc1.RecordSource = "Select * from tblReservation order by STATE_TAX"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 8 Then
Adodc1.RecordSource = "Select * from tblReservation order by LOC_CHARGE"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 9 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_ID"
Adodc1.Refresh
ElseIf DataGrid1.SelStartCol = 10 Then
Adodc1.RecordSource = "Select * from tblReservation order by RES_OP"
Adodc1.Refresh
End If
Do you see where i'm going with this?
I simple want to use a variable in the "select * from <Table> Order by <Field>"
