Time Required: 20 minutes

Class Materials:

  • None

Next we are going to modify the Windows security policy and account settings to support Oracle RAC.

Open a command prompt and enter the following command:

secpol

 
This opens the Local Security Policy interface. Alternatively you can navigate here by using:

Start->Administrative Tools->Local Security Policy

Using the interface, navigate to Local Policies->Security Options and scroll down to User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode.

Double click on this option and change the behaviour to Elevate without prompting.

Next we are going to manually create the ORA_DBA group. Although the installer will do this automatically on Windows, I have had mixed results when using non Administrator accounts, so I prefer to do this step manually.

Open a command prompt and enter the following command:

compmgmt

 
This opens the Computer Management interface. Alternatively you can navigate here by using:

Start->Administrative Tools->Computer Management

Select Local Users and Groups->Groups and right click to add a new group.

Create a new group called ora_dba and add both the Administrator and oracle users to it.

Now log out of Windows and log back in as the oracle user. You can also use the Switch User option to do this.

Once logged in as oracle, open a command prompt and create a new directory called TMP on the boot disk. Usually this is the C: drive.

Now enter the following command:

control.exe nusrmgr.cpl

 
This opens the User Accounts interface. Alternatively you can navigate here by using:

Start->Control Panel->User Accounts->User Accounts

Now select “Change my environment variables” and change both TEMP and TMP to the directory you just created – C:\TMP
