[resolved] JDBC autocommit false

[Anonymous]

Hello All,
I am working with jdbc connection pool and I need to set autocommit to false on jdbc connections and then commit manually. I have connection pool setup in Talend runtime environment and all JDBC components that I used were configured to use data source alias.
My original setup was tJavaflex ->onSubjOK tJDBCRow -> (onSubjOk tJDBCCommit). This setup did not work when I disabled tJDBCCommit despite the fact that I set defaultAutoCommit to false in connection pool config file. When tJDBCCommit was disabled data was still committed to database.
Then I added tJDBCConnection since it has that nice checkbox "Use Auto-Commit" which I unchecked and then I set tJDBCRow to use existing connection from tJDBCConnection. So my setup became as follows:
 tJavaFlex -> onSubjOK ->tJDBCConnection ->onSubjOK ->tJDBCRow ->(onSubjOk tJDBCCommit). 
This also did not work.  Checking the code I was surprised to see that the code generated for tJDBCConnection did not even try to get connection from connection pool datasource.  Looking further I found out that autocommit flag is being set on connection retrieved from connection pool by tJDBCRow but despite that, the job still autocommits. 
I would appreciate any suggestions on how to resolve this issue. I am using Talend Open Studio 6.0 for ESB.
Thank you!
Svetlana

Turned out this doesn't have anything to do with Talend but with AS400 default transaction isolation level which is set to "read uncommitted" :mad:
