Thanks for the posts, somehow I suspect that the HSN did not work properly, because there was a kernel panic situation on the active node (our system has 2 NODEs, one of them is HSN), we will test HSN and see if all what is needed will be replicated automaticaly.
The missing files appeared on the HSN after the crash situation was resolved on the primary NODE. But since we did an patch installation, these files are different again.
The SOs that were missin are in /etc/opt/teradata/tdconfig/udflib/tdbs_1001 (SLES10).
Could someone please point me to a document or describe how can I make HSN to take operation on purpose (this way, we will be able to test also that all the network related settings like firewall are correct)?
What comes to my mind is... If my assumption in the first line is correct, would it make sense to perform replication every time, we install a patch / change external UDFs?
