Oracle Database problems caused by IE8 failure to enter the debug mode

The Oracle database problem caused by IE8 being unable to enter the debug mode. in the B/S system for development, you need to enter the debug mode of IE for debugging. However, the debug window flashed through, you can only turn off the series software. There is no problem before, but the problem only occurs after the  browser is installed. So I tried to uninstall the browser and reinstall IE8. During IE8 installation at www.2cto.com, the computer restarts. When you reinstall IE8 after the restart, the system always prompts that the current IE8 cannot be uninstalled. Therefore, You Cannot uninstall the SDK by using . Find % WINDOWS_DIR % \ ie8 \ spuninst \ spuninst.exe to uninstall the SDK. The uninstall tool is not a perfect tool. For example, after repeated attempts, the installation of IE8 still failed, and the problem became more and more serious, like poisoning. Finally, there is no way to restore the system image that was backed up N long ago. The image is restored, and IE8 is normal. However, the recent Oracle database is gone (Oracle is installed on the system disk). Fortunately, data files are stored on other disks. We had to use the cold backup method to restore the database. Perform the following steps: 1) back up the data file and Copy D: \ oracle \ product \ 10.1.0 \ oradata. 2) open database configuration assistant and recreate the database nciio (the name, file directory, and so on must be consistent with the previous one). Run the command to overwrite the original directory file. 3) Delete the new database file and copy the copied nciio to the Current Directory D: \ oracle \ product \ 10.1.0 \ oradata4 to start oracle-related services (listener and nciio) 5) test. Use pl/SQL connection, error ORA-01033: ORACLE initialization or shutdown in progress prompt www.2cto.com handle ORA-01033 error step: 1) Enter CMD, execute set ORACLE_SID = nciio, make sure to connect to the correct SID; 2) Run sqlplus "/as sysdba", stop the service, and then start SQL> shutdown immediate to stop the service SQL> startup to start the service. check whether there is any data file loading error at startup. 3) check whether there is an error file prompt and find an error file. The system prompts that the password file is invalid. The path is D: \ oracle \ product \ 10.1.0 \ Db_1 \ database \ PWDnciio. ORA needs to re-create the password file to handle this error. The steps are as follows: 1) Delete (or rename the file) the password file PWDnciio after the shutdown service. ORASQL> host del D: \ oracle \ product \ 10.1.0 \ Db_1 \ database \ PWDnciio. ORA otherwise, an error is reported when you reset the password: OPW-00005: File with same name exists-please delete or rename2) reset the password SQL> host orapwd file = D: \ oracle \ product \ 10.1.0 \ Db_1 \ database \ PWDnciio. ORA password = cmd entries = 53) restart the database nciio [nciio is the name of the database in the case] service. If no error is reported, a prompt is displayed. Tabase opened. The operation is successful. SQL> startupORACLE instance started.
