database link - global_names

Hi,

We created a two-nodes rac database using oakcli create database command on ODA x5-2. The default value for global_names is "true" on the database.

Based on Oracle note 210630.1.  

--------------------------------------statements from node 210630.1--------------------------------------

When the source database initialization parameter GLOBAL_NAMES is set to true, the database link name must match the target database global name as it exists in the GLOBAL_NAME

------------------------------------------end----------------------------------------

global_name=true could be an issue on our database system. so, on the testing-stage, we modify the global_names to "false". however,  Before we turn the ODA server to a production server. I would like double check it, if we modify the global_names from true(default value) to false, it's going cause some issues on the two-nodes Rac database? When apply the ODA bundle patch, should we reset the "global_names" back to "true"?
