Hi all, from my Win7 host, I cannot connect to port 1521 for Oracle 11g SE running under a virtual PC running in XP mode. Neither SQL-Plus nor SQL Developer get a connection, although the db is running and locally reachable as tested with SQL-Plus on the guest system. SQL Developer says ”The network Adapter could not establish the connection.” TNSPING says "no listener". So far I’ve opened port 1521 in the Virtual PC’s windows firewall and also allowed SQL Developer through the firewall of the Win7 host. Ping to the VM server works so network is ok (I used the MS loopback Adapter) but port 1521 is not accessible from the host. Any ideas?
