Developer10g and Oracle11g databse on the same machine
After first reboot Oracle 11g database failed to start but I have found the cause: Oracle now looks for listener not in native 11g home but in Dev10g home!!!
So I copied the line "LISTENER_V1120 = (ADDRESS = (PROTOCOL = TCP)(HOST = NEGODV)(PORT = 1521))" from 11g tnsnames.ora into tnsnames.ora in 10g. This resolved the problem but I want to know:
How to force Oracle to use desired listener?
(Note: Oracle11g\bin is placed at the beginning of Windows environment PATH variable).
