I don’t make it to connect from my Win7 host to Oracle 11g SE running under 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.” when I click Test connection or Connect.
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. I’ve set up the network on the guest system and checked that one can browse the internet.
What else could it be that blocks the connection to the guest system?
Many thanks in advance
Software/Hardware used: Oracle SE 11g, Windows XP, Windows 7, SQL Developer
