DbAdapter Merge/Insert

Whilst using DBAdapter the merge/insert operation doesn't seem to recuperate unlike the Select operation , after the database is bounced.It requires the application server to be bounced after the database comes back up for the insert/merge to work !! Am I missing anything ?

Hi there,
merge/insert may take longer to recover from than select because the former because of an issue with transactional contexts.
If the select fails and the connection is recovered, then the select can proceed right there because there is no transactional context to worry about.
If the merge/insert fails and the connection is recovered, I still have to throw the exception if I was in the middle of a transaction. The latest drivers seem to let beginTransaction always pass, so a Merge/insert always fails as the first exception happens midway through the transaction. Unfortunate but just means you need to give merge/insert more retries.
Please see the
integration/orabpel/samples/tutorials/122.DBAdapter/InsertWithCatch
tutorial for how to configure this but basically you need to open the bpel.xml and add two properties to your partnerlink:
<partnerLinkBinding name="BPELSamples">
<property name="wsdlLocation">insert.wsdl</property>
<property name="retryInterval">60</property>
<property name="retryMaxCount">60</property>
</partnerLinkBinding>
You can also define the connection in the data-sources.xml, and then allow the app server to manage the connection pool.
Thanks

DBAdapter Merge failed

Hi Experts,
Does anyone had issue (ORA-00001: unique constraint) while invoking DBAdapter Merge (Insert and Update) to a table
which having a primary key of combination of 3 fields?
My table is :
LOCAL_CURRENCY NOT NULL CHAR(4)
FOREIGN_CURR NOT NULL CHAR(4)
DATE_MOD NOT NULL CHAR(8)
CONV_RATE NOT NULL NUMBER(15,7)
with PK: LOCAL_CURRENCY, FOREIGN_CURR, DATE_MOD
The detail of bindFault from BPEL is:
ORA-00001: unique constraint (TS.SYS_C0013840) violated
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'merge' failed due to: DBWriteInteractionSpec Execute Failed Exception. merge failed.
This fault happened when i want to update CONV_RATE for a particular record in DB.
For example, a record in DB (LOCAL_CURRENCY = 'EUR', FOREIGN_CURR ='USD', DATE_MOD= '20110101',CONV_RATE='1.5') is updated to new CONV_RATE='1.6'.
My environment: SOA Suite 11.1.1.3, DB target Oracle 11g.
Any hints are most welcome.
Thanks.

I am having a similar problem. Trying to perform a merge on DB2 AS400 from BPEL. The table has a composite key with 6 fields (JD Edwards table):
SELECT * FROM DEVDTA.F0902 WHERE GBAID = ? AND GBCTRY = ? AND GBFY = ? AND GBFQ = ? AND GBLT = ? AND GBSBL = ?
When trying to call DB Adapter merge operation for an existing record I get the following error:
<Mar 23, 2011 2:19:50 PM PDT> <Error> <oracle.soa.adapter> <BEA-000000> <JCABinding=> [default/integ_F0902!1.0*soa_e5af67e1-0aba-417a-a7d6-3b1295a14cfe.World_F0902_Sync]:merge One-way operation merge() failed>

Is this a known limitation, or a bug? This is on SOA BPEL 11.1.1.4.

DBAdapter merge operation error

Hello,
I run into a problem when trying the DBAdapter merge operation. I believe the merge operation first executes a query operation based on the primary keys, if not found, then will execute an insert operation, my problem is when I pass in the input as " " for one primary key, seems the merge operation internally transform it to "" then do the query, so there is no record found, then it will do the insert with the right primary key " ", which results in the violation of the unique constraint (suppose I inserted a record with primary key " " before).
Does anyone have any suggestion for this?
Thanks.
Leo

I'm using database triggers as well, if your acquanted with pl/sql that would be the 1st choice, especially because you can generate the needed triggers for all your audit columns.
On the other hand you can define annotations in JPA, EJB3.0 now to populate your audit-columns automatically, maybe this can be done as well in the toplink mapping files?
It should be possible, but I don't now until which level annotations are supported in toplink used by the dbAdapters.

Oracle 10g Merge Insert performance

Hi All,
Performance wise, is it better to use a regular insert statement or Merge (insert only) statement ... in Oracle10g. (no updates are used in this merge statement).
Thanks for the input.

thanks for the comment ... here is the more info for INSERT alone using Merge ... thought Oracle has a reason for this to add in 10g.
http://www.oracle-developer.net/display.php?id=310
I am looking for right answer about the performance

Unique constraint is not thrown when used MERGE INSERT (alone) via dblink.

We found some interesting behaviour of unique constraint on Merge query when we use Merge When Not Matched Insert (no update query) via a dblink.
In one Schema S1, on Table A1(c1,c2,c3) there is a unique constraint on column (c1,c2).
Column c2 is nullable and has null for some records.
Now i have a table A2 with same defintion as A1 in Schema S2.In S2 , i have a dblink of S1 as S1 itself.
I have data in S2.A2. Here also i have some records with c2 as null and c1 matching with the data of S1.A1.
Now from schema S2,
I am using the following Merge Query,
MERGE INTO S1.A1 target
USING S2.A2 source
ON (target.c1 = source.c1 and target.c2 = source.c2)
WHEN NOT MATCHED
INSERT (c1,c2,c3) values (source.c1, source.c2,source.c3)
WHEN MATCHED
UPDATE c3 = source.c3;
Now when i execute this merge in schema S2,
if i have some data in S1.A1 and S2.A2 having c1 as same and c2 as null, as oracle does not treat two nulls same, it goes for an insert, i have got unique constraint violated error.
But if i execute MERGE INSERT alone, though that record is getting inserted , i am not getting unique constraint violated error.
Oracle version we are using is 10g (10.2...).
Is it a bug in oracle or what could have caused this behaviour.

Dear,
ERROR at line 1:
ORA-00001: unique constraint (SYS_C00137508) violatedYou need to think about two things
(a) read consistency : what was the situation of table_1 when the maching clause has been initially evaluated ; there were 0 rows matching which means the merge operation will be all insert
(b) your matching clause has a problem : the join column must be unique in both tables otherwise the merge will be ambigous. You don't have a unique key on the source table
(c) think that the merge operation will never insert id =1 and then update id = 1 within the same operation. This will never happen
Hope this helps

Weblogic OSB 10.3 DBAdapter merge not working

I am using the DBAdapter to execute a database insert or update from a Publish Action. When using the merge operation it is not performing an update but instead always performing an insert, therefore I always get a unique constraint error due to the record already being in the table.
Is there something special I need to do in order to tell the mapping file which fields are the primary key so it recognizes it needs to be an update versus an insert?
Thanks in advance

I figured it out, the toplink file had every column specified as the primary key, once I only used the correct keys, it worked just fine.

DBAdapter Merge

Trying to update a table using DBAdapter and Merge operation. The table has besides other columns creation_date and last_update_date. What is the best way to populate the creation_date and last_update_date to sysdate when inserting a row, and only populate last_update_date when updating a row in the database?
Thanks,

DBAdapter insert only operation issue

Hi Gurus,
I'm trying to create the BPEL SOA composite which is receive the input using File Adapter (file only containt 2 rows) and insert into database table using DBAdapter with Insert only operation using mediator.
The data will be inserted to seeded employees table in hr schema.
1st try, i got error constraint violated because i did not provide the last name (NOT NULL constraint).
I updated last name of the same data and try again, but i got error constraint violated for email (UNIQUE constraint).
Mar 27, 2015 2:13:15 AMMessageError during invoking 2-way operation "insert" on target service "FdyWriteEmpToDB"

Hi Fendy,
could you look inside the audit trail in the enterprise manager to see if the transformations is really working? For what I see, I think there is an error in your xslt. It should be like this:
<top:EmployeesCollection>
    <xml:for-each select="/imp:Employees/imp:EmpDetail">
    <top:firstName>
      <xsl:value-of select ="/impl:FirstName" />
    </top:firstName>
    <top:LastName>
      <xsl:value-of select ="/impl:LastName" />
    </top:LastName>
<top:email>
      <xsl:value-of select ="/impl:Email" />
    </top:email>
    </xml:for-each>
</top:EmployeesCollection>

Will insert (ignore duplicates) have a better performance than merge?

Will insert (ignore duplicates) have a better performance than merge (insert if not duplicate)?

Ok. Here is exactly what is happenning -
We had a table with no unique index on it. We used 'insert all' statement to insert record.
But later when we found duplicates in there we started removing them manually.
Now, to resolve the issue we added unique index and added exception handling to ignore DUP_VAL_ON_INDEX exception.
But with this all records being inserted by 'INSERT ALL' statement gets ignored even if only one record is duplicate.
Hence we have finally replaced 'insert all' with merge statement. Which inserts only if a corresponding record is not found (match based on column in unique index) in the table.
But I am wondering how much performance will get impacted.

DbAdapter (nolock in merge operation)

Hello,
I'm currently with performance problems when I do various operations on a SQL Server 2000 using a dbAdapter(merge operations).
I did some analysis in the database and realized that I am having lock in "select" operation, and I have to wait for the "update". How can I add the command "nolock" at the end of this query?
Thanks
Zanatto

Yes, this is to prevent confusion when the merge result falls outside of the active filter and is thus hidden from the user. Sometimes it will, sometimes it won't - so we chose consistency of behavior.
You should be able to prevent this by clicking the padlock icon in the upper right of the grid view and filter area. This will lock the filter.

DBAdapter and Sequcne on 10.1.3.3

I have an issue regarding using native sequnce in DBAdapter to insert a new record into database.
For Bpel 10.1.2
I have to problem to use native sequnce by setting *mappig.xml and oc4j.xml.
For Bpel 10.1.3.3 I saw "cnnot insert NULL" error. I am not sure why.
==The error message
ORA-01400: cannot insert NULL into ("AP"."AP_INVOICES_INTERFACE"."INVOICE_ID") Error Code: 1400 Query:InsertObjectQuery(<ApInvoiceLinesInterface {<ApInvoicesInterface null />} null />)</detail> }}
==Setting on my ApInvoice.xml
<opm:primary-key>

</toplink:sequencing>

I did some experiments
I created a sequence TESTAN_S start with 50 increment by 50.
I have inserted 300 rows using DB adaptrer with native sequencing option.
The ID's in table are incremented by 1 staring with 50 ie 50,51,52,53.....upto 351..
This is wrong as sequence.nextval should always be incerments of 50 not 1. I dont know why this is happening. What is the significance of preallocation size tag?
Here are the steps I followed to achieve this. its working somewhat but not exactly what i was expecting. I just changes the files manually and did not run any wizards after changing the files manually.
1. On the Top link I have selected Native sequencing Option and pre allocation=50 and Save
2. Open the bpel/servicename_toplink_mappings.xml and add sequence.. see the xml pasted below.

ESB-DBAdapter issue

Hi all,
I have DBAdapter to insert records into oracle XE DB from my ESB process.
Though the record gets successfully inserted,the ESB instance is itself
marked as errored.
The following is the stacktrace
oracle.tip.esb.server.common.exceptions.BusinessEventRetriableException:
An unhandled exception has been thrown in the ESB system.
The exception reported is: "oracle.tip.esb.server.common.exceptions.BusinessEventRejectionException:

The exception reported is:

Any help/insight will be very helpful.

We have same issue as yours.
But worst for us, we need logical delete the record in Source database. And if this Exception happen, the transaction will roll back.
A oracle guy told me this is an internal bug:5519509 only in 10.1.3.1. I don't know when it will be fixed.

Multiple record insert thru PROCEDURE - Urgent

All,
My requirement is, I have to invoke a procedure which accepts two input and 1 out variable. The operation of the procedure is to insert the data to two tables(head_tab and line_tab-accepts multiple record). I used %rowtype for the two inputs i.e procedure proc(head_var head_tab%rowtype, line_var line_tab%rowtype, out_var out number). The incoming doc comes from 3rd party application which sends a header record and multiple line record for the same header.
I used the transformation activity, to insert line record I used for-each loop for multiple record. But %rowtype being a scalar data type, it doesn't accept array of record to it! I'm stuck here. Can we achieve this scenario with using of procedure? or should I configure DBAdapter to insert the data directly to the table rather the procedure does this? If we can achieve it thru procedure, how can I go about?
Thanks,
Sen

Hi,
I believe you should change the signature of the procedure.
I tried below code for my proc to send multiple records without use of for loop.
Type line_var_rec IS RECORD(
Var1;
var2;
Type line_var_tab IS TABLE OF line_var_rec INDEX BY BINARY INTEGER;
Type head_var_rec IS RECORD(
var3;
var4;
line_var line_var_tab ;
Type head_var_tab IS TABLE OF head_var_rec INDEX BY BINARY INTEGER;
proc(head_var IN head_var_tab, out_var out number);
With the above code you can insert multiple header records each having multiple line records.
Pls let me know if u have any questions.
