I was using a tnsnames.ora entry with 2 IP addresses, when the client load balancer put me on a busy node the server tried to redirect me on the other one. It was doing so returning the host name of the other node. That network name was unknow in my PC so I was getting the same error you are facing. Since the db was at a customer site and was not listed by our internal dns the simplest solution was to add the hostnames to my hosts file. hope it helps, Giovanni On 1/13/06, johan Eriksson wrote: > Hi all > > I have a problem with our RAC env. which I cant figure out. > > Oracle is 10r2 and the OS is RHEL 3 and we have 2 nodes in the RAC. > > If i from machine 1 connects to rac1, rac2 it works and if I connect to > rac I am switched between the nodes as expected. > The same is for machine 2. > > But if I connects from my pc (oracle 10r2 here also) and try to connect > to rac I alway gets into rac2, but 40% of the times I get the message: > ORA-12545: Connect failed because target host or object does not exist > > which I intertpret as it tries to log me onto rac1 but fails to do so. > > Am I right in my assumption and where to start solve the problem? > > /johan > -- > http://www.freelists.org/webpage/oracle-l > > > -- -------------------------------------------------------------------- Another free oracle resource profiler http://sourceforge.net/projects/oraresprof/ Now version 0.9 -- http://www.freelists.org/webpage/oracle-l
