5.1 Problems Installing Oracle Services for MSCS

If you are running Oracle Universal Installer on a system that does not have MSCS installed (such as a client system) and you try to install Oracle Services for MSCS, the installer will display an error such as that shown in Figure 5-1.

If a message such as that shown in Figure 5-1 appears, do not continue with the installation. Click OK to back up through the installation windows and choose another Oracle Real Application Clusters Guard installation type (described in Chapter 2).

5.2 Problems with the User Rights Policy

For Oracle Services for MSCS to run, the "Log on as batch job" and "Log on as a service" user rights policy must be enabled for the user account under which Oracle Services for MSCS runs. Typically, the Oracle Real Application Clusters Guard installation enables this policy for the user account during the security setup. However, in some situations, the user rights policy might not be enabled correctly on a backup domain controller (BDC), because the account database on the BDC is read-only and cannot be changed directly.

To solve the problem, perform these steps:

1. Perform one of the following operations:
   • If the primary domain controller (PDC) is part of the cluster, install Oracle Real Application Clusters Guard on the PDC.

   • If the PDC is not part of the cluster, grant "Log on as batch job" and "Log on as a service" rights to the Oracle Services for MSCS user account on the PDC.

2. Synchronize the account database with the BDC (using the Server Manager administration tool).

3. Install Oracle Real Application Clusters Guard on the BDC.
