Create PDB via DBCA

Good Morning,

We have just installed a DB on a new server. 

And we try to install the first pdb from the DBCA and when we try to validate with the sys user it always returns the following error:

#####

[DBT-05513] Failed to connect to the database (XXXXXXX).

Cause - Specified database credential is not valid to connect to the database (perdocp). Action - Specify a valid sysdba user name and password to connect to the database. 

#####

We can connect without problems with the sys user as sysdba to our database from the sqlplus from the command line.

[oracle@SERVER1 ~]$ sqlplus sys@XXXXXXX as sysdba
