AOA Dear friends I have just manged to install Oracle 6i runtime environment through wine under Ubuntu 10.10. I have also installed Net80 products from Oracle6i CD. Actually I have to run some oracle6i Applications under Ubuntu10.10 through wine. When I open the application via ifrun60.exe then the form comes correctly but it is not connecting with database although I have one correct entry in TNSNAMES.ORA. My TNSNAMES.ORA. contains: estab = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = 192.168.41.71) (Port = 1521) ) ) (CONNECT_DATA = (SID = misdata) ) ) So please guys what I have to do to configure the TNS settings. Thanks in advance.
