2. Pre-Requisites
•An Intel processor based PC running the Windows 7 32-Bit Operating System
•RAM: At least 4GB (8GB or more is better, especially if you will also use Oracle’s development tools)
•Swap Space: At least 3 GB
•Disk Space: At least 10 GB Free space (even though Oracle says only 4GB is needed, you will need more)
•Some Antivirus software programs have been known to block certain parts of Oracle installation.
• Also the Windows firewall may need to be configured to allow Oracle database to open up ports such as port
1521 and 1158
•Make sure your PATH environment variable is shorter than 1,000 characters
•Open up the CMD prompt and echo %PATH% to see how long it is.
•If it is longer than 1,000 characters, get the Properties of the Computer and edit your existing environment
variables
• until the path is below 1,000 characters.
•It is likely best if any prior Oracle versions have been removed before installing this new version.
7. • Once the new database is configured, the summary screen will appear as shown below. Click on the “Password
Management” button to unlock some of the accounts (especially to work with Warehouse Builder and BI tools).
8. • Once the new database is configured, the summary screen will appear as shown below. Click on the “Password
Management” button to unlock some of the accounts (especially to work with Warehouse Builder and BI tools).
• Set password
9. Installation
• OracleServiceORCL – This is the main DBMS service that runs the database engine. On a serve this should
be set to automatically start when the server boots up. If you will only use Oracle once in a while, you may
wish to set this to start manually. This way you can turn it on when you need it.
• OracleOraDb11g_home1TNSListener – This is the “listener” service that allows Oracle clients to connect to
the database running on your server. By default it will open up TCP port 1521 to accept incoming connections
and then forward those connections to the database service. Most of the Oracle development tools and
middleware will need to be able to talk to this service.
• OracleOraDb11g_home1ClrAgent – This is the service that supports .NET connections and executions
within Oracle database. The CLR stands for Common Language Runtime which is Microsoft’s “virtual
machine” environment for running .NET applications (e.g., written in C# or Visual Basic.NET). If you do not
plan on using .NET, this service can be safely disabled or left on Manual setting.
• OracleMTSRecoveryService – This is the Microsoft Transaction Services integration service that allows
Oracle databases to participate in distributed transactions. Unless you will be developing MTS applications,
you may leave this service set on Manual setting.
• OracleJobScheduler – This service supports the Oracle remote jobs scheduling package. If you do not
intend on writing applications with the DBMS_SCHEDULER, you may leave this service Disabled.
• OracleDbConsoleORCL – This service supports the Oracle Enterprise Manager web service that runs on port
1158.
• Oracle ORCL VSS Writer Service – This service supports the Oracle Volume Shadow Copy backup and
recovery functions. Even though it is set for Manual startup, it will start when the main Oracle database starts
up.
10. Uninstallation
STEP 1:Uninstall all Oracle components using the
Oracle Universal Installer (OUI).
• Uniliversal Installer
• Deinstall products
• OraDB11g_home1
• Remove
STEP 2:
• Run regedit.exe and delete the
HKEY_LOCAL_MACHINESOFTWAREORACLE key.
This contains registry entires for all Oracle products.
Delete any references to Oracle services left behind
in the following part of the registry:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSet
ServicesOra* It should be pretty obvious which
ones relate to Oracle.
• Reboot your machine.
• Delete the "C:Oracle" directory, or whatever
directory is your ORACLE_BASE.
11. Uninstallation
• Delete the "C:Oracle" directory, or whatever directory is your ORACLE_BASE.
• Delete the "C:Program FilesOracle" directory.
• E:apprath
• Empty the contents of your "C:temp" directory.
• Empty your recycle bin
• NOTE:For 64-bit Windows (x64), you need also to delete the
HKEY_LOCAL_MACHINESOFTWAREWow6432NodeORACLE key from the registry.
