This article is about how to install and uninstall Oracle. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

ORACLE installation steps

1. Extract win32_11gR2_database_1of2.zip and win32_11gR2_database_1of2.zip to the current directory (PS: select two compressed packages and right-click to extract them to the current folder; you must extract them at the same time, and you cannot extract them separately, otherwise the files will be overwritten)

2. Set file compatibility after decompression: enter the database folder and right-click setup.exe Properties-compatibility.

3. Double-click setup.exe to install and wait for the installation interface to appear after the doc window appears (10 seconds to 10 minutes)

4. Enter the installation interface

A) cancel acceptance of security updates

B) Select installation options here to create and configure the database

C) system class select desktop class (server class: as the name implies, it is used by the server)

D) Select the installation path-> you can customize the path if you have a default path, but if you customize it, you only need to modify the drive letter path and it will be generated automatically.

E) the prerequisite test may fail here because the computer configuration is too low, just check all and ignore it.

F) Summary regardless of direct click to complete

G) automatically pop up the copy file window after the product installation is completed

H) password management

5. Test whether the installation is successful

Test through sqlplus / as sysdba and select * from dual; instructions

ORACLE uninstall step

Delete the registry information first-then stop the process service (and delete the process)-finally delete the file

1. Delete registry information

Run the doc directive (regedit) to open the registry

The 32-bit operating system finds the ORACLE directory in the HKEY_LOCAL_MACHINE\ SOFTWARE directory of the registry and deletes it directly.

The 64-bit operating system finds the ORACLE directory in the registry's HKEY_LOCAL_MACHINE\ SOFTWARE\ WOW6432Node directory and deletes it directly.

2. Stop process service (and delete process)

Run the services.msc directive to open the process service to stop all running Oracle processes in the service

Run the sc delete directive as an administrator to delete all processes that begin with Oracle

OracleOraDb11g_home1TNSListener

OracleOraDb11g_home1ClrAgent

OracleMTSRecoveryService

OracleDBConsoleorcl

OracleJobSchedulerORCL

OracleVssWriterORCL

3. Delete the app folder and C:\ Program Files\ Oracle folder under the installation directory

(if the app directory on ps:win7 system cannot be deleted, you can right-click the app directory-the administrator takes ownership and then deletes it.

Prompt file is occupied by another process, make sure that the uninstall is correct, there is no residue, you can restart the computer and delete it)
