The installation of oracle11g on 64-bit Windows 7 server encountered problems and the problem that it could not be deleted.

The installation of oracle11g on 64-bit Windows 7 server encountered problems and the problem that it could not be deleted.

Today, I have downloaded oracle11g in win7, deleted it, unloaded it, and restarted it four or five times. I will explain the following points on the Internet:

Unzip and copy all the content in the second decompressed win64_11gr2_database204 F2 \ database \ stage \ Components to the win64_11gR2_database_1of2 folder. This is to prevent the installation package from being small;

2. All operations must be performed with a management identity. This is a question about win7 permissions. Why?

1), win64_11gR2_database_1of2 \ database \ setup.exe right-click and select "also run as administrator" to execute setup.exe

2) cmd should also start with the Administrator identity --> all programs --> attachments --> "command prompt" --> right-click and click to run as administrator; due to win7 permission problems, although we use the administrator account, we do not use the administrator permission when running cmd. Therefore, we do not have the permission to access related directories.

Iii. Oracle 11g Default User and password Problems

Username/password logon identity description
Sys/change_on_install SYSDBA or SYSOPER cannot log on normally. It can be used as the default system administrator.
System/manager SYSDBA or NORMAL cannot log on with SYSOPER, which can be used as the default system administrator
Sysman/oem_temp sysman is the user name of oms
Scott/tiger NORMAL user
Aqadm/aqadm SYSDBA or NORMAL senior queue Administrator
Dbsnmp/dbsnmp SYSDBA or NORMAL replication Administrator

Logon identity: indicates the Role specified during logon. SYSDBA and default are supported in oracle11g.

PS: when installing Oracle 10 Gb, the system prompts you to create a database and prompts you to enter a password when creating the database. If you enter a password at this time, when you log on to the database, the password corresponding to the user name sys should be the password you entered when creating the database. Instead of the default manager.

4. Uninstall and delete data in a clean manner (check whether oracle exists in the following items)

1. Right-click "computer" --> Management --> services and applications --> services to stop all Oracle-related services.

2. Start --> all programs --> Oracle Installation Product --> Universal Installer. After the "welcome to use" interface is started, uninstall the product --> Expand OraDb11g_home1 under the Oracle main directory --> select Oracle Database 11g11. 2.0.1.0 --> Delete --> select "yes" in the pop-up Confirmation window ". After the uninstallation is complete, select "close" on the "product list" page that appears, and then select "cancel" on the "welcome to use" page to exit the interface.
Unmount all Oracle products, but the Universal Installer cannot be deleted.

3. Start --> Run regedit and enter the registry.
1) Select HKEY_LOCAL_MACHINE \ SOFTWARE \ ORACLE and press del to Delete this entry.
2) Select HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services to scroll through the list and delete all Oracle entries (Keys starting with oracle)
3) Select HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Eventlog \ Application to delete all Oracle entries.
4) delete all keys prefixed with Ora or Oracle in the HKEY_CLASSES_ROOT directory.

4. Choose computer> Properties> advanced system Settings> advanced> environment variables to delete Oracle settings in the environment variables CLASSPATH and PATH.

5. Delete All Oracle-related directories (if the directories cannot be deleted, restart the computer and delete the directories again:
1) C: \ Program Files \ Oracle directory.
2) Oracle installation directory, such as D: \ app

If the file is large, you can use the command to forcibly Delete C: \ Users \ Administrator> rd/q/s d: \ app

3) C: \ WINDOWS \ system32 \ config \ systemprofile \ Oracle directory.
4) C: \ User Name \ Oracle
5) if the [ORACLE] Tag segment exists in the WIN. ini file, delete it.

6. Delete all groups and icons related to Oracle from the desktop, STARTUP group, and program menu.


7. In Event Viewer, delete Oracle-related logs.


8. restart the computer to completely delete the Oracle directory.
