The answer is negative, I have experienced once, huh, huh, now I will now solve the process described once, with the reader. On that day, the heavy mounting system, after the .NET software, started the Oracle9i. My Oracle installation disk has been copied to the local Oracle backup folder. Start installing, when the file is loaded to 99%, suddenly Holding a fault, strange, morning, copy to colleagues, he can install, why can't I do it. Depressed ... After the Oracle installation failed, the system was required, because oracle was deleted, so it was very troublesome. After calm, I checked the relevant information, poured a cup of tea and started to solve the problem. First, delete C: / Program Files / Oracle, pay attention to the automatic uninstallation of the installation failure, must do it yourself. In addition, delete the D: / Oracle directory. At this time, just remove the Oracle entity on the hard disk. Because when you install a file, you will be updated on the registry. Therefore, first back up the registry, then modify the registry. Ok, move soon ... Start -> Run -> regedit-> OK. Enter the registry editing screen, first export the registry, save it. Then, in HKEY_LOCAL_MACHINE-> SOFTWARE-> Oracle's entire directory. Next, look for the Oracle field in the registry, if you want to delete your key value, then, F3, find one, delete one, empty the registry all the value of the Oracle-related field. Based on my personal experience, if you installed the system, then add Oracle, only hkey_local_machine-> software-> Oracle-> Software-> Oracle in the registry is only related to Oracle. So you can delete this. If .NET, PL / SQL, etc. are installed, some keywords in these software will appear Oracle fields, but these fields do not affect Oracle installation, so only hkey_local_machine-> Software-> Oracle is available, You don't have to delete the fields of other software. Once these delets, you should reinstall Oracle. The strange thing is why my colleague can install from the Copy's Oracle on my machine, and I can't do it? After the comparison discovered, he COPY is in the bookup of the backup, it is full English and mine is "Oracle Backup". At this time, I think of it, remember where it is seen, Oracle requires that the original path and the target path cannot have illegal characters, such as: Chinese, space, etc. Yes, I changed to "Oracle_Backup" and then reinstalled, everything OK. After installation, test, start, everything is good, good sense of accomplishment. :) The next day, starting oracle everything is normal, suddenly discovered that their machine name does not meet the company's norms, and then the machine name restarts the machine and discovers Oracle hang. FAINT, what happened? What is the Oracle root machine name is also implicated, view the service: OracleraHome92tnsListen is started again, it is automatically turned off. The service will be automatically changed to manually, then in the CMD window, the result is an error message appears: SID is wrong.
