Q: After installing oracle, I can connect to the server with PL/SQL. Why are the commands for creating and opening oracle datasources gray in iDesktop?
A: Firstly, check if the system PATH contains the Oracle installation path. If not, manually add it to the PATH system variable. Secondly, check whether Oracle is 32 bit if iDesktop is 32 bit. If iDekstop is 64 bit, Oracle must also be 64 bit.
