Integration

Hi everyone, this is the first time I use the OSB 11.7 to connect to a DB2 AS400 database. I think i've done that the right way, I was able to create my db adapters with JDeveloper, to setup a datasource in Weblogic even to use a business service to do a simple select on a table, but when I try to do an update I get the following message:

Pure SQL Execute of UPDATE SCHEMA.TABLE SET COL1 = ? WHERE COL2 = ? failed.
Caused by java.sql.SQLException: [SQL7008] TABLE of SCHEMA not valid for operation. (Translated from spanish)

I already tried to use XA vs NoXA transaction and both of them with One-Phase Commit and still the same error. I am sure it is not about permissions because I'm able to do the updates from DBeaver client. My JCA looks like this:

<interaction-spec className="oracle.tip.adapter.db.DBPureSQLInteractionSpec">

     <property name="SqlString" value="UPDATE SCHEMA.TABLE SET COL1 = #COL1 WHERE COL2 = #COL2"/>

     <property name="QueryTimeout" value="30"/>

     <property name="GetActiveUnitOfWork" value="false"/>

</interaction-spec>

What else should I do in order to accomplish the goal of the update? Thank you so much for your help!
