HDR questions
Couple of questions on HDR for the wise. We are at the testing stage of an ODBC-based application and want to test failover. HDR was working fine until I shut down both the instances and set DRAUTO to 1 on both sides; now the primary and secondary just say they can't find one another. I can connect across the instances fine in client-server. Any pointers? The standard DR error message is less than instructive. Next question: client failover using DBPATH. Our testing guy reckons the only way to switch servers is to manually alter the IPS address and INFORMIXSERVER in the ODBC config. He's convinced the DBPATH method won't work over ODBC. I reckon this is B.S. but I haven't touched ODBC for so long I don't know how to refute him. (Surely you just somehow switch between multiple connections?) What's the ODBC-based approach? Many thanks Andy
