Question on BPEL Process Performance

Question

Hello,
We have a BPEL process reading the datafile through file adapter and upserting into DB using DB Adapter. Our requirement is
If there are 10 records to process and two records (record 5 and 9) fail while inserting/updating for some reason(i.e data type mismatch, column length mismatch etc..), at the end of the process you should see 8 records in the destination table and two records in error table.
I know there are solutions of this :
*1) Multiple calls to DB:* Use a While loop in a BPEL process and Invoke DB adapter for each record and use exception handling(Catch all block).
*2) Invoke Store Procedure:* to prevent multiple calls to DB, create a stored proc on DB side to iterate and insert the records and the stored proc should also return the IDs of failed records back as error response so that you can insert those failed records to a log table or in log files.
Can you suggest which solution is best in terms of performance and why ??
Also we need to perform some business validation (i.e NOT NULL check, date format check etc..), Where should we perform this.. at DB level or BPEL process level?? and why..
Thanks,
Buddhi

Answer 1

BPEL is a slow performer.
Always call a stored procedure to do complex data processings.
Hence go with the second approach.
Error records:
If your going to log errors in the same database, insert the error details direcly into the error table. Dont go back to BPEL.
Application specific validations should be handled in the application itself.
