Can SYS_GUID() function generate same guid at another db

Question

I am planning to use SYS_GUID() function to generate primary key in an existing table(Primary key does not exist in that table as of now)

I wanted to know if in certain case if we sync data from one database to another , is it possible that Oracle generate same guid at another db ?

Thank you

No. GUID is Globally unique. See alsi the documentation https://docs.oracle.com/cd/B13789_01/server.101/b10759/functions153.htm
