Improve Database adapter insert performance

Hopefully this is an easy question to answer. I'm getting passed to my BPEL over 8,000 records and I need to take those records and then insert them into an Oracle database. I've been trying to tune the insert by using properties like inMemoryOptimization, but the load still takes severl hours. Any suggestions on how to get the Database adapter to perform better or load all 8,000 records at once? thanks in advance.

Hello.
8000 records doesn't sound "huge", unless a record is say 1 kB then you have 8 MB, which is a large payload to move around in one piece.
A DB merge is typically slower than an insert, though you did say you were using an insert.
If you are inserting each row one at a time that seems like it would be pretty slow.
Normally the input to a DB adapter insert is a collection (of rows) vs. a single row. If you have been handed 8000 individual rows you can assemble them into a collection with an iteration - tedious in BPEL but works fine.

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

I have a database connection called bpel samples in jdev. Can anyone help me in creating bpel process to insert data in a table using database adapters.
I am not able to get any output for any of the database adapter tutorials. Any hints????
Thanks in advance.

The database version is only important with the dehydration store. If you are using the adapters to select / delete / update / insert data into your application it comes down to the jdbc drivers. Basically if you are above 8i you should be fine.
olite is a very basic database, and the jdbc drivers are flaky, it's also not based on the Oracle code, therefore is not upgradable if you want to increase performance. You would need to perform some manual steps to migrate to a standard database.
If you are wanting to do basic tutorials and don't want to have a heavy database using all your resources, use oracle XE. No need to pact. If you have a oracle database installed somewhere use that.

Database Adapter: Insert, relationships, sequences and problems of course

Hello Everyone!!
I'm trying to do an insert in an Oracle Express Database with a database adapter. I'm trying to do the insert in two tables: SOLICITUDES with a column called NUMSOLICITUD that is also the primary key of the table and it's populated from its own sequence and the other table whose name is DOCJUST with a field NUMSOL. SOLICITUDES has a 1:M relationship with DOCJUST and the fields used in this relationship are NUMSOLICITUD and NUMSOL. The problem is that when the adapter do the insert, the first insert made on SOLICITUDES is correct, but when it tries to insert in the DOCJUST table, when it's supposed to insert in NUMSOL the same value inserted in NUMSOLICITUDES instead of that, a NULL value is inserted in NUMSOL so the process fails. Is it because the NUMSOLICITUDES column is populated from a sequence? How can I resolve that?
Thanks!!

Hi,
OK, I found the following article: http://soa-bpel-esb.blogspot.com/2010/04/understanding-catch-and-catchall.html
Using the info from that article I have created a test flow, which contains the same insert database adapter as the production flow. I have placed the Invoke within its own scope and attached a "CatchAll" block to this scope. To this block I have added a "empty" step (do nothing).
In my tests, I see the desired results i.e. the second time I initiate the flow with the same data, the CatchAll block executes, which does nothing, and processing continues after the scope.
So far so good - my query is how would I catch the specific error of unique index violation rather than general catchall?
As before, and assistance/comments greatly appreciated.

Database adapter for performing sync read of N records at a time

Would anyone have an example and/or documentation related to performing a select operation in a database adapter where the adapter can fetch N number of records at a time? The database adapter would not be an activation agent/point polling for changes to any records, but invoked in the middle of the process. I searched for this in the samples folder and online but found nothing.
Any help would be appreciated.
Thanks.

Hi,
Do you want to know the best way to integrate Oracle BPEL to OTM? Then it's simple webservice call from BPEL using http binding.
If you want to connect to Apps inbound then you can either use DB adapter or JMS adapter or Apps adapter which ever best suites your business requirement.

How to improve database and application performance

Bhatiathere is no simple answer. There is no DATABASE_FAST=TRUE initialization parameter. There are a myriad of reasons why an application is performing poorly. It could be that the application (code and data relationships) is poorly designed. It could be that individual SQL statements are poorly written. It could be that you don't have enough cpu/memory/disk bandwidth/network bandwidth.
You need to determine the root cause of poor performance and address it. If you application is poorly designed, you can tune the database until the cows come home and it won't make any difference. If you are trying to run 100k updates per second against a database hosted on hardware that only meets minimal requirements to install Oracle ... well, hopefully you get the picture.
First, go to tahiti.oracle.com. Drill down to your selected Oracle product and version. There you will find the complete doc library. Find the Performance Tuning Guide
Second, go to amazon.com and browse titles by Tom Kyte and Cary Milsap. I particularly recommend "Effective Oracle by Design" and "Optimizing Oracle Performance", though I see a lot of new titles that look promising (I think I'll be doing some buying!)

Database Adapter insert operation with return value

Hi All,
I have a table with auto generate parimary key in DB2 database. I need to have an insert operation ont this table which should return current value of primary key after insert.
For this , I have created an insert operation in DB Adapter. But this insert operation in oneway operation.
Is there any way I can create an Insert operation in DB2 adapter which returns the primary key value?
Thanks
--Sree

Hi Sree,
With insert operation it is not possible. You may use stored procedure/function to perform insert and return the required value, and call this SP/function using DB Adapter.

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.

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).

Insert Multiple records using Database adapter with Stored procedure func

Hi All,
I want to insert multiple records on a database using a stored procedure. I wanted to insert those records using a Database Adapter and the Database adapter should be invoked by a Mediator.
Can somebody suggest me with ideas whether it can be acheived with OOB capabtilities in SOA suite or not?
Thanks for your help in advance.
Thanks,
Shiv

The use case you want to achieve is feature supported by the DBAdapter and it is possible to invoke the same from mediator.
Please have a look at the oracle documentation and you should be able to get the necessary information.
The below links should help you as well:

Database Adapter: How to Insert when one column is an identity column

Hi everyone
I'm developing a BPEL process who uses a database adapter to insert a row in a table of an SQL Server database. The problem is that the database adapter tries to insert a null value into the field that is the primary key of the table so the process fails. This is because I don't want to specify any value to this field because this field is specified in sql server as an identity column so this field doesn't need to have a value provided.
I suppose the only solution is to set the database adapter to not insert any value to this field but how can i do that? is there any way to make the database adapter to insert data in only a few fields of a table and not in all fields, trying to insert null in these fields that no data have been provided?
Thank You Very Much!

In JDev->Applications Navigator->your project->Application Sources->Toplink->toplink_mappings.
Upon selecting "toplink_mappings" in the structure window you will see the package. Expand to see your tables. Double click your table and it will open file in main area. Select your field that has identity column. And at the botton you will see "Use Sequencing" check box make sure you uncheck it.
This will solve your problem.

Problem inserting a clob using bpel and database adapter

We are having issues inserting a clob field into the database when the data is over 4000 characters. Anything under 4000 characters works fine.
The error we are seeing is "Error while converting to a Java struct object. Unable to convert XSD element P_RESPONSE_ARRAY_ITEM whole user defined type is QC_CRCBT_PKG_RESPONSE_TYPE. Cause: java.lang.ClassCastException: oracle.sql.CLOB; nested exception is: ORABPEL-11802"
We are using BPEL 10.1.3.3 and a database adapter. THE PL/SQL parameter decomposes to a clob type. Again, anything under 4000 characters works fine.
Any ideas?

This is likely due to Bug-6629539, which has just been identified and fixed in 11. You can request a one-off patch for this bug (i.e. a BLR off of the 10.1.3.3.0 release label).

How to improve database link performance?

Hello all,
We use db links to do DML operations on remote databases. For OLTP applications we are facing performance problems for transactions dependent on data on remote database.
For legal and business reasons we cannot state all the data locally.
Could anybody suggest how to improve database links performance or suggest methods/procedures/techniques to enhance speed of OLTP applications going against remote databases ?
Thanks
Sky

AQ is as reliable as Oracle-- the guarantees about delivery of queued messages are the same as the guarantees about committed transactions (i.e. ACID). AQ is designed for asynchronous operation, though. If you are batching transactions, it sounds like you are already doing some sort of asynchronous operations-- I've generally found AQ a lot easier to administer & maintain than rolling your own batching system.
If you want to tune the Oracle side of things, you'll need to explain more about the system(s) involved here. Architecture, data flow, operations that involve the dblink, etc. If you're not comfortable posting that sort of information to a public forum, feel free to send me mail directly [email protected]
As an aside, I'm interested in how you can legally pull data from the remote system to display to your users but that you can't legally cache that data in your system via replication. Sounds like an odd constraint.

Database Adapter: cannot access table with complex record type as columns

Hi all,
I cannot perform any operations on a table that has columns with complex record type.
I have created a table to store purchase order details.
Sample script:
CREATE type XX_CUST_INFO_TYP as object
ssn VARCHAR2(20),
rating NUMBER(15)
CREATE type XX_ITEM_TYP as object
item_name VARCHAR2(20),
unit_price NUMBER(15),
quantity NUMBER(15)
CREATE table XX_PORDER (cust XX_CUST_INFO_TYP, porder XX_ITEM_TYP);
When i try to access the table X_PORDER in jdev through a database Adapter, i receive the error as
"some tables contains columns that are not recognized by the database adpter"
1.) so in this case, how to include such tables that have complex types?
Also, check out this scenario also..
1. add a table through a database adapter
2. drop the table in backend
3. i can still see the table and its structure in the database adapter wizard even after restarting Jdeveloper.. How is it possible?
These are some really interesting scenarios to experiment. Please suggest your ideas on this..
Thanks All!

Hi Hem,
for a select you could select against a view. And for inserts you could create a stored procedure. They support complex types since 10.1.2. Complex types support in tables/views was added for 11 (next major release).
You might be able to use PureSQL as a workaround too, i.e.
insert into XX_PORDER values (XX_CUST_INFO_TYP(?,?), XX_ITEM_TYP(?, ?, ?))
As for your other problem, in 10.1.2/10.1.3 the DBAdapter wizard sits on top of the Jdev Offline Tables and TopLink Mapping Workbench components. When you remove a table in the wizard it won't delete the Offline DB component. It was added by the wizard, but afterwards it is public to the entire Jdev project. You must remove it from Jdev yourself. This has been improved for the next major release too, no artifacts from underlying components are created.
To remove it select:
Offline DB Objects -> <schema> -> <table> and try File.. Erase From Disk.
Thanks

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:
Can't find partnerLinkType 2.
in
"file:/D:/soft/SOASuite/product/10.1.3.1/OracleAS_1/bpel/domains/default/tmp/.bpel_BPELAdapter_1.0_e82210b05e4d3e997eed581d0d220293.tmp/_BPELAdapter.wsdl" WSDL to find PartnerLinkType "{http://xmlns.oracle.com/pcbpel/adapter/db/datain/datain_plt"。
How to resolve?
Thanks,
Melody

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.
in
"file:/D:/soft/SOASuite/product/10.1.3.1/OracleAS_1/bpel/domains/default/tmp/.bpel_BPELAdapter_1.0_e82210b05e4d3e997eed581d0d220293.tmp/_BPELAdapter.wsdl" WSDL to find PartnerLinkType "{http://xmlns.oracle.com/pcbpel/adapter/db/datain/datain_plt"。
