I don't know much about this kind of thing... all i know is that i want to put oracle 9i onto my server, but there was already a version of oracle already, which appeared to be Net8 or something like that.
When opening up installer to try and remove Net8, there were about 15 different options to remove. I didn't know what to remove and nobody else I asked seemed to either so i tried to remove all of them. But, I got errors for about 5 of them saying that if i removed that program then it would affect other programs i use.... so of course i really don't want to mess up this server so i left it there.
I tried to remove it because the first time i tried to install Oracle Client 9i it said that i cannot install into an oracle home which already has something in it. So, after that it occured to me to try and create a new oracle home. I did that and it started to install except for lots of errors coming up saying 'I/O Error while opening or reading file C:\Docume~1\DUBLIN~1\Locals~1\Temp\1\OraInstall 2010-04-20-0-59-03PM\temp221' (with the only thing changing being temp221 will become temp222 etc). So, I just tried to skip those files of which there was probably about 20.
Then it appeared to install. So, I tried to see if I could connect to the database I wanted to connect to and not surprisingly it didn't work. Tried using TOAD and got an error 'cannot resolve TNS name'. Tried through visual studio and go the error 'OraOLEDBpus.dll: The specific module could not be found' so i guess that could have been one of the 20 or so files that didn't install properly.
Either way, it looks like a mess, and i want to try and just remove everything related to oracle 8 or 9 or whatever and start again, or just get the 'version' installed now working properly.
What should i do at this stage?
