Multiple instances on one server

Hi, I tried to run a second instance of IDS 7.30 on one machine for testing purposes. Obviously I need additional entries in sqlhosts file and a separate onconfig and /etc/services as well, since I tried ontlitcp. But when I try to initialise the second instance it will show Error -25572: Network driver cannot bind a name to a port. I am pretty sure that there are no typing errors. sqlhosts: dehamca1 onipcshm dehamca1 dehamca1 dehamca1_tcp ontlitcp dehamca1 i_net dedev1_tcp ontlitcp dehamca1 i_net where the last line should be the second instance. The variable ONCONFIG is set to onconfig.dedev1, which contains all settings for this instance. The file onconfig.std is a link to onconfig.dedev1. Does anybody know why this happens? How do I get both instances to run? Thanks --------------------------------------------------------------------------- --------- Kai Shen Acer Computer Germany I.T.
