Hello,
Can somebody help me to find out, why I receive "ORA-12203: TNS:unable to connect to destination" error when using SQL CONNECT command from ProC program to connect to remote Oracle server from Sun-20 running Solaris 2.4 and Oracle 7.2?

Output from "adapters" command is:
Installed SQL*Net V2 Protocol Adapters are:

   V2 BEQ Protocol Adapter
   V2 IPC Protocol Adapter
   V2 TCP/IP Protocol Adapter

Output from "drivers" command is:
Installed SQL*Net Drivers are:
V1 Pipes
V1 TCP/IP
SQL*Net V2

I can connect to the same instance from PC's attached to the Sun. tnsnames.ora file on the Sun is pretty similar to one on PC.

Thanks in advence,
