RunTime binding of database adapter.

Hi All,
I am trying to work through a requirement where the ESB uses a DB adapter to extract information from various data sources (databases), which have the same table structres.
Design is to have a single interface, which would connect into the source system, wherein the connection string needs to be passed through the adapter at run time.
Please advice how this can be achieved.
Regards,
Sambhav.

Thanks for the reply Marc.
Your advise is good, however, for my design, invoking a SQL package would be an overkill..is it possible that we can override the behavour of the JCA to achieve run time binding?
Regards,
Sambhav.

Multiple stored procedure in Database Adapter

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.

Any help is greatly appreciated.
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

Database Adapter - Using in Clause

In the Database adapter - I need to generate a Query like
Select * from employee where empid in (1,2).
empid - is a integer column
I have tried the pure sql option and generated a query like Select * from employee where empid in (#ids).
In the transformation, I am creating a comma separated string for ids and have bound it to ids variable.
The above works for a single ID but throws an binding error when multiple Id's are passed.
Whats the best way to handle 'In' Clause on a integer column? (There is no issue with string columns - multiple values can be passed)

You will need utility PL/SQL function for that:
create or replace type myTableType
as table of number;
create or replace function str2tbl( p_str in varchar2 ) return myTableType
as
l_str long default p_str || ',';
l_n number;
l_data myTableType := myTabletype();
begin
loop
l_n := instr( l_str, ',' );
exit when (nvl(l_n,0) = 0);
l_data.extend;
l_data( l_data.count ) :=
ltrim(rtrim(substr(l_str, 1, l_n - 1)));
l_str := substr( l_str, l_n+1 );
end loop;
return l_data;
end;
and then in Db Adapter:
Select * from employee where empid in ( select * from TABLE ( cast ( str2tbl( #ids) as myTableType ))
Hope that helps,
Adam

Database Adapter using Logical Delete Polling Strategy not updating field

I have an ESB database adapter defined against a table. The adapter is set to use the Logical Delete Polling Strategy, and the table has an extra column defined as the "delete" field. When I register the adapter to the ESB and add a record to the table, the adapter reads the contents of the record as expected. However, 15 seconds later (that being the polling interval) it reads it again, and again 15 seconds after that, ad infinitum.
I have defined the logical delete field as a single character field and set the Read value for "T" (a record is normally inserted with that field having a null value). Results as outlined in the previous paragraph. I redefined the field as a number and set the Read value to "1" (with a record normally inserted with that field having a value of "0"). Results as outlined in the previous paragraph.
Apparently the update of the logical delete value to the Read value is not occurring. My question (obviously) is: Why?

Database Adapter Logical Delete Not Working....

Hi,
I have an issue with the DB Adapter under BPEL GA 10.1.3.1. I'm trying to do a logical delete on a table however the logical delete isn't updating the records to show that they've been processed.
I've created a simple test case with a 3 column table sitting in Oracle XE DB with the third column containing the logical delete flag. I've created a new process consisting of a DB Adapter partnerlink and a receive. In the logs (below) I can see the Select statement followed by the Update (logical delete) occurring but the Update statement just actually run against the DB. I can copy the update statement and run this through SQL as the same DB user and it updates the records.
Has anyone seen this before?
Thanks.

Hi,
I haven't yet used 10.1.3, but we had a number of issues under 10.1.2.0.2 around caching and upd/ins/del.
A number of things we changed were
- set usesBatchWriting to false in oc4j-ra.xml file
- set identityMap to NoIdentityMap via toplink work bench
- set should-always-refresh-cache-on-remote,should-disable-cache-hits,should-disable-cache-hits-on-remote to true in toplink mappings.xml file (note this last one is only if toplink was not used to insert the source data).

Java.sql.SQLException: Invalid column index in database adapter

I have a query that works fine if I run the sql in a JDeveloper SQL editor, but I get a "java.sql.SQLException: Invalid column index" error if I paste it in a database adapter. If I put this query in the adapter:
select <column>
from <table>
   where <column> in (select
    trim( substr (txt,
          instr (txt, ',', 1, level ) + 1,
          instr (txt, ',', 1, level+1)
             - instr (txt, ',', 1, level) -1 ) )
      as token
    from (select ','||#bindVariable||',' txt
            from dual)
connect by level <=
     length(#bindVariable)-length(replace(#bindVariable,',',''))+1)I get the error. But if I just put the sub query in the adapter as:
select
    trim( substr (txt,
          instr (txt, ',', 1, level ) + 1,
          instr (txt, ',', 1, level+1)
             - instr (txt, ',', 1, level) -1 ) )
      as token
    from (select ','||#bindVariable||',' txt
            from dual)
connect by level <=
     length(#bindVariable)-length(replace(#bindVariable,',',''))+1the error goes away. Does anyone know what might be causing this?
Thanks in advance

Hi,
Could you please make sure your binding style(Oracle Positional,Oracle named..etc) of the Seeded VO and Custom Vo are same.
This is the option you will get when you are extending your vo. So make sure that both are same.
You can refer the below link too
VO extension leads to "Invalid column index" exception

Dynamically Pass sql query in Database adapter

hi',
How can we dynamically pass sql query in Database adapter, is there any way, I am using SOA 11G.
Thanks

Conditional where clauses in database adapter

I am trying to write a query in a database adapter that allows for conditional where clauses. Specifically, I want to include or not include a where clause (and clause) if an input variable is empty or not. Can a prepared statement with lexical parameters be used in a database adapter? Or is there another way to do this?
Thanks in advance.

I am afraid that you can only bind parameters to the SQL, you can't bind the SQL itself to the SQL. We do have QueryByExample support, where based on what fields are set in an example object, it will construct a different SQL select.
If you pass in
<Address>
<street/>
<city>
<state>CA</state>
</Address>
it will return all addresses in California. If you pass in:
<Address>
<street/>
<city>Los Angeles</city>
<state/>
</Address>
it will return all addresses in Los Angeles.
Thanks
Steve

How to pass dynamic values to JDBC Database adapter in PureSQL operation?

I want to fetch the records from the table via JDBC database adapter with the criteria but I should not hardcode the values inside my query. I am using Execute by PureSQL operation. Values might change in future and it is the reason I should not hardcode the values and instead I should pass it dynamically.
This is my query:
SELECT FROM Table0 t0, Table1 t1 WHERE t0.Field1= 'ABC' AND t0.Field2= 'DEF' AND t0.Field3 = 'CBA' AND t1.FLAG IS NULL AND t1.Field1 = t0.Field4*
The values 'ABC', 'DEF', 'CBA', 'NULL' are not fixed and it can be changed. Hence, I need to pass the values for these fields dynamically. What must be passed in the query and where to pass the User Defined Values during the run time.
Please can anyone suggest how to resolve this. I am using SOA 11g.
Thanks in advance.

Hi,
Ensure that you use the Adapter Configuration Wizard to do the query modification suggested by Arik. This will allow the schema for the DB Adapter getting created automatically. Also revisit this schema to assure that the data types of the bind parameters (parameters with #) have been correctly populated in the schema.
You can get some help from this too although this doesn't fully match your use-case.

Dynamic JNDI name for database adapter in BPEL

Hi All,
I am having some major issues trying to make the JNDI location for the database adapter dynamic (10.1.3.4). I already went through the followin link, but that didnt work for me: http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html
The below example works, but only the first run. Second time around the first runs JNDI value gets retained and connects to that database.
This is what worked atleast the first time.
I parameterized the JNDI with a variable defined in the partnerlink definition in the bpel.xml
In Bpel. xml
<partnerLinkBinding name="updatetbl">
<property name="wsdlLocation">updatetbl.wsdl</property>
<property name="CONN">eis/DB/na</property>
<property name="retryInterval">60</property>
</partnerLinkBinding>
In the updatetbl.wsdl file
<service name="updatetbl">
<port name="updatetbl_pt" binding="tns:updatetbl_binding">
<jca:address location="$CONN"/>
</port>
</service>
At run time I change the partnerlink CONN variable in embedded Java.
try
Element targetAdapterElement =(Element)getVariableData("Invoke_getFromTbl_OutputVariable","getFromTblOutputCollection","/ns2:getFromTblOutputCollection/ns2:getFromTblOutput/ns2:SRC_JNDI");
getLocator().lookupProcess("JndiIssueTest").getDescriptor().getPartnerLinkBindings().getPartnerLinkBinding ("updatetbl").setPropertyValue ("CONN",targetAdapterElement.getTextContent());
("updatetbl").getPropertyValue ("CONN"));
catch(Exception ex)
addAuditTrailEntry("Error is " + ex);
This works fine the first time, but the second time I run it to look at a different CONN value, it somehow still connects using the first runs value!
If I redeploy or clear the WSDL cache, it works. But we plan to run it multiple times from several environment so manually or programatically clearing WSDL is not the right solution.
Can someone tell me what is the standard process of doing this so it works everytime?
Thanks,
Shaf

Shaf,
Please refer the mail thread for details. If you want I can send you(send me your email id) the sample BPEL process which uses Dynamic JNDI.

Can't connect to Database from Database Adapter in BPM 11g

I added a database adapter in BPM 11g to the composite.xml. This database adapter is just to load data into a XML document (UI payload). I can’t seem to get a connection to the database. I am getting a error, see below.

The docs says I need to add an Outbound Connection Pool to to SOA DbAdaptor in WebLogic. The problem is I can’t seem to make my changes take effect. This is the same error recorded here:
BPEL DB adapter
The problem is when trying to change the property, xADataSourceName, the changes don’t take effect. I also notice that in our test environment I get a dialog box to change the deployment plan. On my local WLS, I don’t get this dialog box. Either way the changes to xADataSourceName will not take effect.
There must be a simple solution, I just don’t see it.
Any help is greatly appreciated.

Edited by: M Peterson on Jul 15, 2010 5:33 AM

When you enter the xADataSourceName property, did you hit enter on the field? If you simply tab off the field and hit save changes without hitting the enter key then it doesn't record the change to the property.

Error with Database adapter

Hi All,
I am using a database adapter to write values to database.The build was successful.However when i test it in the console with the sameple input I am getting the below error.

Can anyone help me out to fix this error.
Thanks in advance.

From the error it is clear that your composite is not able to find the DB jndi.The JCA Binding Component is unable to startup the Resource Adapter specified in the <connection-factory/> element: location='eis/DB/DB_Conn'.
Please follow these steps:
1) Have u created DB jndi eis/DB/DB_Conn that you are using on weblogic console.
2) After creating did you redeploy the DB adapter on weblogic console.
3) If you have done above 2 steps cross check your jndi exists in ur DB adapter or not on weblogic console.
That could only be the possible reasons for the error you are getting.
Hope this helps.

Database adapter causes deadlock

We use database adapter on 3 standalone tables with no FK. At the beginning of the process, we do a read
<jca:operation
ActivationSpec="oracle.tip.adapter.db.DBActivationSpec" ...>
At the end we do an update with
<jca:binding />
<operation name="merge">
<jca:operation
InteractionSpec="oracle.tip.adapter.db.DBWriteInteractionSpec"...>
That is, two db adapters at two ends.
We have got deadlocks with <lock-mode>1</lock-mode> or <lock-mode>0</lock-mode>.
We ahve two bpel nodes (10.1.2) in a cluster running on 10g RAC.
Any suggestion of avoiding deadlocks?

If you are using SOA Suite 11g you can use query by example option to achieve part of that.
It support only equality check but on dynamic number of fields
