Can multiple versions of the Apache listener coexist on the same NT machine?
Yes, but they must be installed in separate ORACLE_HOMEs and all but one of them must be started from the console. For example, to start the listener for the Early Adopter’s Release, execute the following from a command prompt (directory paths may be different on your machine): cd D:\Oracle\Portal30\Apache\Apache set PATH=D:\Oracle\Portal30\bin;D:\Oracle\Portal30\Apache\Perl\5.00503\bin\mswin32-x86;
