Queries regarding Database adapter ...

Hello,
I have a scenario where i need to query few tables which are not related to each other and i am having different queries for each table. I tried creating a single DB adapter and imported all the tables in it. But i got struck at two places where i was asked to define a root table and also to define a select query.
I have following doubts reagrding this:
1. Do i need to need create different DB adapter for each table?
2. What is the significance of root db table?
Regards

Yes, you would create 3 different partner links using the DB adapter.
In theory yes you would create a new partner link using the DB adapter for each table that is unrelated. If you want to select PO_HEADERS_ALL and PO_LINES, this can be done in one call as they are related.
This advice is based on the fact that you are selecting batch data, not single lines of data. If you are receiving 1 row from multiple unrelated table this could be achieved via a custome procedure / package. I don't want to steer you down the wrong path so I would need to know more of your use case. In most senerios in Oracle apps you are calling APIs / packages.
If you could provide more information of your use case(s) I will try and provide better advice

Sql queries in database adapter

Hi,
I want to write, say, 2 select statements in the database adapter. How can I accomadate using "execute pure sql"?

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!!

Using the Service Link Database adapter

I had a question regarding the use of the Service Link database adapter. We've configured an adapter that will write rows to a certain table in an oracle database. The rows are written into the table correctly. I've also configure the inbound portion of the database adapter to retrieve records but there are 2 problems.
1. When creating the SQL that is used to poll the database table, I'm not able to use the channel id namespace. According to the manuals and training materials that I have reviewed, it looks like you should be able to call #channelid# in your query and the system should automatically translate that. I've tried #channelid#, #channel-id#, and #ChannelID# but if doesn't seem to covert the value to the actual channel ID. Can you use namespaces in the polling query?
2. If I setup the queries without namespaces, I can get into the next step where it excutes the sucessful or failed sql query. I setup a simple transformation that automatically closes the assocaited task when the query is run. I then setup a SQL statement to delete all rows in the table (I only did this because I could not target a row without the channelid namepsace working). The problem is that when I submit a task that uses the agent, the agent polls the database and finds the task. The agent then closes the asscaited task, per my transformation, but when it goes to delete all rows in the table, the rows are not removed. If I execute the same SQL using the same account in a SQLPlus window, the rows are deleted so I think that my SQL is good. I'm not sure why it does not work and the only message in the log is:
2010-07-08 15:52:23,677 DEBUG [com.newscale.is.adapter.db] [ AgentId-5 ] Fetched 1 new records
2010-07-08 15:52:23,804 ERROR [com.newscale.is.adapter.db] Outbound Message Failed to deliever
This is my SQL: delete from rcowner.rcapprovals where STATUS_code='Registered'
Any help or advice is apprecaited.
Tim

Hi Tim -
The namespace that you can use comes from the SELECT SQL statement. So you need to write out the Channel ID into a field in the db table (you need it around anyway for the transformation). Then the inbound SQL needs to include the channel ID field in the select statement. Then the success/failure SQL statements can reference the channel ID field from the inbound SQL.
Inbound example: SELECT CHANNEL_ID FROM MYTABLE WHERE STATUS = 2
success example: UPDATE MYTABLE SET STATUS=3 WHERE CHANNEL_ID=#channel_id#
(Note that it seems to convert field names to all lower case. And the #channel_id# is just referencing the field from the other query -- it isn't a namespace or anything.)
Your delete statement probably isn't working because the db connection is still using the records from the inbound query. Its looping through each record from the inbound query and performing the transformation, then running the success/failrue sql before going onto the next record.

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!

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.

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,

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

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

PollingInterval in database adapter

Hi,
I have SOA 11g with two nodes. I have a database adapter that polls a table after every 30 seconds and perform logical delete on the rows read. I came across interesting situation. When one node is up and PollingInterval=30, it works okay and polling is done right after 30 seconds but when both nodes are up the PollingInterval property doesnt work as expected. It will poll after 24 seconds and then second node will again poll after 6 seconds (node1+node2=30 seconds in total).
Just wondering if I am missing something or doing something wrong? I want each node to run after 30 seconds (i.e only one instance after 30 seconds). My JCA file is:
<connection-factory location="eis/DB/myConn" UIConnectionName="Connection1" adapterRef=""/>
<endpoint-activation portType="MY_DATABASE_ptt" operation="receive">
<activation-spec className="oracle.tip.adapter.db.DBActivationSpec">

<property name="QueryName" value="MY_DATABASESelect"/>
<property name="MappingsMetaDataURL" value="MY_DATABASE-or-mappings.xml"/>
<property name="PollingStrategy" value="LogicalDeletePollingStrategy"/>

Any help will be appreciated.
Thanks!

Hi,
Just have at look at this can be helpful
http://javaoraclesoa.blogspot.ca/2012/04/polling-with-dbadapter-in-clustered.html'
This reserved value (MarkReservedValue in _db.jca) causes an instance of the process to set an identifier. This identifier is skipped by the other polling instances in the cluster.*

Transaction commit in database adapter

Hi,
When the commit happens when a database adapter inserts a record.
I have two invoke process one is db adapter to insert records and second the db adapter to call the procedure to update the records inserted by first adapter, but will the records will be visible in the second adapter.
Please advice, thanks in advance.
Regards,
SReejit

Yes because it is one transaction, therfore you can roll back if the second fails.
But if you perform a dehydration, e.g. wait, human task, receive activity then the first insert will be committed. so you will not be able to roll back. You will need to use a compensate activity.

Ref cursors in Database adapter

Hi,
Is the database adapter capable of handling ref cursors as the datatype of the output parameters of a pl/sql procedure?
For instance if I have the following in my package-spec:
TYPE SomeRecordType IS RECORD
( record_pk mut_table.record_pk%TYPE
, person_nr person_table.person_nr%TYPE
, field_1 mut_table.field_1%type
, field_2 mut_table.field_2%type
, field_3 mut_table.field_3%type
TYPE SomeCursorType IS REF CURSOR RETURN SomeRecordType;
PROCEDURE read_records
( cursor_out OUT SomeCursorType
, exception_code OUT number
, exception_message OUT varchar2
Can the database adapter call the read_records procedure?
I've never seen this in any doc. I know it can't handle record types (that is in 10.1.2 it couldn't as far as I know). So I figure that the above is not possible.
Thanks in advance.
Regards,
Martien

We have successfully used a sys_refcursor OUT parameter for a database procedure call and which is used by a DBAdapter to return a single dataset.
At the time I remember attempting to use a strongly typed ref cursor as the parameter. I think this is what you are attempting to do. I rejected this approach at the time as I was not able to do this. It was, in our case, as simple as using the system defined ref cursor type (i.e. weakly typed).
The handling of the returned dataset was not immediately obvious, but can be handled by as fairly simple XSL transformation to a locally defined variable of the requisite xml structure. I won't describe in detail how to do it as it is specific to our process. Suffice to say the transformation loops over all result rows assign via a test to the correct result field in our local variable.
e.g.
<xsl:template match="/">
<ns1:BatchRequest004>
<xsl:for-each select="/db:OutputParameters/db:P_SCHSHP_REF_CUR/db:Row">
<ns1:statusRqst>
<xsl:if test='db:Column/@name = "ID"'>
<xsl:attribute name="id">
<xsl:value-of select="db:Column[1.0]"/>
</xsl:attribute>
</xsl:if>
</ns1:statusRqst>
</xsl:for-each>
</ns1:BatchRequest004>
HTH and that I haven't misidentified your problem.

Database Adapter: NVARCHAR2 datatype in stored procedure

Hi,
when I try to define partner link as database adapter - call stored procedure with datatype NVARCHAR2, I'm getting following error:
Error while writing wsdl file .....
Exception: WSDLException: faultCode=OTHER_ERROR: Database type is either not supported or is not implemented. Parameter INP_TEL is of type NVARCHAR2 which is either not supported or not an implemented datatype.
Is it possible to wokaround this problem without changing datatype nvarchar(utf16) to varchar2(iso8859p2)?
There should be no difference between mapping of varchar and nvarchar to string at BPEL side.
BPEL version: 10.1.2.0.0
Regards
Karel

Better workaround is to define stored procedure with varchar datatype, generate wsdl
and then change stored procedure definition to nvarchar.
This works and mapping (java) string to (oracle) nvarchar2 is correct.
But sometimes this could be difficult ( invalidations of thousands objects).
Maybe there could be better solution like add mapping to some files ???

How to invoke a stored procedure in database adapter

Hi All,
i have created a database adapter which contains a stored procedure, the procedure is merge process,which bring data from another database,
i have made sure that checking for new records and updating any changes from the source database everything has been taken care in the procedure.
my question is how to invoke this process, what all process activities need to be associated with the database adapter, to invoke it
assuming i want to run it every 5 hours,
any reply would be of great help.
Regards
Ananth

Hi,
V thanks for you reply, i am v much new to this bpel environment, i tried using invoke but got errors like
Error(61):
[Error ORABPEL-10107]: Invalid initial activities
[Description]: in line 61 of "C:\jdevstudio10134\jdev\mywork\Incremental_refresh\data_incr_refresh\bpel\data_incr_refresh.bpel", Initial activity is invalid. An initial activity must be of a receive or pick activity..
[Potential fix]: Please re-arrange the BPEL process definition to make sure its initial activity is of a receive or pick activity. (e.g. by adding new receive activity or removing invalid initial activities..
Error:
[Error ORABPEL-10063]: missing initial receive activity
[Description]: in "C:\jdevstudio10134\jdev\mywork\Incremental_refresh\data_incr_refresh\bpel\data_incr_refresh.bpel", there is no receive activity that starts the process.
[Potential fix]: make sure one of "pick" and "receive" activities have attribute "createInstance" set to be "yes".
later i used the service pick, so from pick i am heading to ivoke and later to finally database adapter, but still getting below error

Thanks

Hi,
Tried that too. No luck. Gives me this.
The selected operation process could not be invoked.
An exception occured while invoking the webservice operation. Please see logs for more details.
oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException: Exception occured when binding was invoked.
Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'selectUsingIn' failed due to: Pure SQL Exception.
Pure SQL Execute of select interface_id, property_name, property_value from ( (?) ) failed.
Caused by java.sql.SQLSyntaxErrorException: ORA-00903: invalid table name
The invoked JCA adapter raised a resource exception.
Please examine the above error message carefully to determine a resolution.

Dynamic where clause in database adapter

Hi
I have requirement to develop SOA service for search page! The back-end query for search is required to have where clauses to be appended to SELECT statement dynamically depending upon search criteria the user selects!
E.g. if user is searching employee from a portal! If employee selects mobile number of the employee, or joining date range or other criteria, then accordingly appropriate clauses are to be appended to SEARCH SELECT statement.
Can we achieve same while implementing executing database query through database adapter from BPEL service?
Thanks In Advance
Priyadarshi

It is difficult using the standard database adapter approach. You may have to use nested sql queries.Following is a good example of the same.
Neeraj Sehgal - Experimenting with SOA: Pass multiple parameters, dynamic query in Pure SQL in Database Adapter
If your only problem in using this that you are hard coding the connection details , you can use the datasource jndi name in the query. hence you will not be required to change your code when moving from one env to other env. You just have to take care of keeping the jndi name same in all the env.
