Do I need to manually set the CLUSTER_DATABASE parameter when using dbua upgrade?
Source:
Is Manual Setting Of CLUSTER_DATABASE Parameter Required For DBUA Upgrade? (Documentation ID 741081.1)

Applicable:
Oracle Server-Enterprise Edition-Version: 10.1.0.2 to 11.1.0.8
Information in this document applies to any platform.

Objectives:
When manually upgrading RAC databases, the parameter CLUSTER_DATABASE has to be set to FALSE. Is this required during upgrade using DBUA?

Solution:
DBUA will automatically set this parameter to FALSE even if it is enabled. you do not need to change the CLUSTER_DATABASE parameter when upgrading using DBUA. you shoshould see information similar to the following in the DBUA trace. log, which confirms that this parameter has been changed:

[Thread-274] [12:56:2:742] [PreMigration.executeStepImpl:146]  Bounce the database in pre Upgrade[Thread-274] [12:56:2:742] [Database.shutdownOPSDuringMigration:1631]  is Windows false[Thread-274] [12:56:2:743] [Database.shutdownOPSDuringMigration:1632]  Database Version = 10.2.0.2.0[Thread-274] [12:56:2:743] [Database.shutdownOPSDuringMigration:1635]  Set cluster_database=false
