JDBC Outbound Adapter Problems


We have a problem with our Outbound JDBC Adapter. This Adapter writes IDOC's into a ORACLE-Database.

After a certain amount of records the procedure breaks down with the error: ORA-08177: can't serialize access for this transaction.

Here is the configuration of the adapter out of the adapter-engine:

  1. jdbc adapter java class


##Adress for XMB endpoint



##DB Adapter specific parameters (example for SQL-Server, see docu)

    1. Which version of Oracle database do you use?

    2. Are you sure that your db was patched? There is a patch for a bug that causes ORA-08177.

    3. Which transaction isolation level do you use? I suppose that SERIALIZABLE, cos Oracle generates ORA-08177 error when a serializable transaction tries to update or delete data modified by a transaction that commits after the serializable transaction began.

      I have get a message from SAP Support. There was a developer, his send me solution for my problem. The problem is that at the sp4, is a parameter name db.transactionIsolation default on SERIALIZABLE, this was not in sp3. The solution is that you can change the parameter with 0,1,2,4 und 8






      For my problem i must change the parameter to


      in my Adapter script and it is running. Great!!!!!

      About this Parameter, you can read in the new document SAP XI 2.0 SP5, but i don' t have it. I hope, i get this document from SAP
