The Oracle Data Integrator 10.1.3.4.6 cumulative patch is now available. If you are using or plan to use ODIInvokeWebService as part of your data integration / governance plans, I recommend applying the cumulative patch.
The patch can be obtained from Metalink ( http://metalink.oracle.com ) .
The patch number is 7485029. The ODIInvokeWebService fix ( bug number 7238234 - ODIINVOKEWEBSERVICE IS UNABLE TO PROCESS LISTS AS WS ARGUMENTS ) is within the 10.1.3.4.6 patch.
Have you got your application / solution to connect to ODI by WebService? Have you integrated from ODI to another application by WebService? Which Application / Solution? Post your answer as a comment, I would be interested in knowing the user experience of inbound/outbound applications that ODI has been used successfully when integrating by WebServices.
If using ODI and WebServices, I highly recommend being on at least patch level 10.1.3.4.4, and going to 10.1.3.4.6 shortly. I am upgrading my Oracle Data Integrator environments to 10.1.3.4.6 today.
