Hi Hazi,

nice example of virtualization+cloud usage :slight_smile:
Please send us Eureka Log (should be available for Access Violation errors). I can also recommend you to convert model from Oracle 10 to Oracle 11, you should not try to update Oracle 10g model from Oracle 11g database directly.

Also, please update your TDM to the latest 3.6. version. Thank you.




Hi Hazi,

I overlooked the attachment. I saw this post:
and thre is no attachment.

We will look into the matter tomorrow.

Note: please don’t send the same question to multiple sections. Thank you.




Thanks Vaclav,

I have updated to version 3.6 and will change the model to 11g and will report back.



Hi Hazi,

please try to test and repair your model.
This is what I can recommend. Unfortuntely, from the log file we didn’t recognize what caused the problem.
