I am installing oracle 10.2.0.1 on Windows 2003 sp1 (Std.Edition) on 32 bit. After installing the oracle suite. I am unable to see the oracle related services but only one service is visible in services.msc i.e. isql service.But this is unable to start properly it is in the state of "starting". It is strange to note that one one oracle service is there but I am unable to found other oracle services such as Tnslistner etc. When I am shutdown isql service for patch installation of 10.2.0.2 error is pop up saying that i*sql service is unable to start. Any help on this greatly appreciated.
