The following error is issued:
"SQL or RefineryXacute Failed: Site: 9 Error has occurred while processing data stream org.w3c.www.protocol.http.HttpException: Unable to contact target server xxxxx.com:50000 after 1 tries".
This comes each time after 301 seconds, so looks like a timeout. The processing on the remote target server takes more then 400 seconds and if I shorten the processing by reducing the rowcount number, it works well. I increased all connection timeouts to more then 600 secs - on the IP21OLEDB data server, and the UDS instance.
We are using xMII 12.0 and I can not see the transaction ExecutionTimeout property which was existing on 11.5 with value 300000. I added a global property with the same name with bigger value, but this did not help.
The UDS version is 126.96.36.199.
