Oracle 10g is not difficult to install on win, but it is not very easy on other platforms. Our company uses RHAs 4 as the server and I work on databases. It is relatively simple to uninstall on other platforms. It is okay to delete files and environment variables. However, it is not so easy to delete files and environment variables on win. Now I will write down how Oracle uninstalls it on Oracle.
Software environment:
1. Windows XP + Oracle 10g
2. Oracle installation path: D: \ oracle
Implementation Method:
1. Start-> Settings-> Control Panel-> management tools-> stop all Oracle services;
2. Start-> Program -> Oracle-oradb10g_home1> Oracle Installation products-> universal installer uninstalls all Oracle products, however, the universal installer itself cannot be deleted.
3. Run regedit, select HKEY_LOCAL_MACHINE \ SOFTWARE \ oracle, and press del to Delete this entry.
4. Run regedit, select HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services to scroll through the list and delete all Oracle entries.
5. Run refedit and select hkey_local_machin. E \ System \ CurrentControlSet \ Services \ Eventlog \ Application, delete all Oracle entries;
6. Choose "start"> "Settings"> "Control Panel"> "system"> "advanced"> "environment variables". Delete Oracle settings in the environment variables classpath and path;
7. Delete All Oracle groups and icons from the desktop, startup group, and program menu.
8. Delete C: \ Program Files \ oracle directory;
9. restart the computer to delete the Oracle directory.
10. Delete Oracle-related files, select the default Oracle directory c: \ oracle, delete the entry directory and all subdirectories, and delete the following file oracle from the Windows XP directory (generally D: \ windows. INI, oradim73.ini, oradim80.ini, oraodbc. INI, etc.;
11. Win. if the INI file contains a [Oracle] Tag segment, delete the segment.
12. If necessary, delete all Oracle-related odbc dsn;
13. In Event Viewer, delete Oracle-related logs. Note: if some DLL files cannot be deleted, restart and start new installation, during installation, select a new directory. After the installation is completed and restarted, the original directory and file can be deleted.
