enabling Database Vault on e-business RAC database

Right now I'm in a process to setup Database Vault for an E-Business suite database. This is a 2 node RAC cluster.
The DB is with April 17 BP.

As the DB exists already, I followed How To Enable Database Vault in a 12c database ? (Doc ID 2112167.1).
Everything looks smooth, but unfortunately, at the Configuration of DV
exec dvsys.configure_dv('DVOWNER','DVMANAGER');
failes with
ERROR at line 1: 
ORA-47500: Database Vault cannot be configured. 
ORA-06512: at "DVSYS.CONFIGURE_DV", line 23 
ORA-06512: at "DVSYS.CONFIGURE_DV", line 72 
ORA-06512: at line 2 

ORA-47500 tells
47500, 00000, "Database Vault cannot be configured."
// *Cause: The Database Vault configuration failed because some Database Vault  
//         objects were missing.
// *Action: Run the dvremov.sql script to remove Database Vault and then
//          reinstall Database Vault.

This was the first try: remove DV and start again.
Nothing changed.

Some research on MOS led to Known Issues In A Database Vault Environment (Doc ID 2330775.1)
there the explanation for ORA-47500 is:

Cause: There are many invalid objects in the database.

Solution: Run $ORACLE_HOME/rdbms/admin/utlrp.sql to validate the invalid objects

So all invalid objects were removed/fixed and - DV enabled again.
With same error.

A lot more investigation and a SR was required here.

When catmac.sql was run it completed and didn't show any hints it failed at the end.
Especially register DB and it's validation were shown successful:
  2      num number;
  3  BEGIN
  4      dbms_registry.loaded('DV');
  5      SYS.validate_dv;
  6  END;
  7  /

PL/SQL procedure successfully completed.

After a lot more investigation, an issue in the (manually activated) spool of catmac.sql was found:
ERROR at line 1:
ORA-31011: XML parsing failed
ORA-19213: error occurred in XML processing at lines 49
LPX-00217: invalid character 21 (U+0015)
ORA-06512: at "DVSYS.DBMS_MACADM", line 160
ORA-06512: at line 2
and this error stack leads to Installation Of Database Vault Fails With ORA-19213, LPX-00217: Invalid Character 21 (U+0015) (Doc ID 2324871.1)
As so often: the problem looks obvious, but only after it was found.

The problem is the environment variable
Which is a requirement for Oracle E-business Suite.

Here RAC has it fair share of complexity as this environment is not (only) defined in a .bash_profile or similar, but also in cluster registry:
srvctl getenv database -d <DB_UNIQUE_NAME>

The fix was to disable this setting:
srvctl unsetenv database -d <DB_UNIQUE_NAME> -t ORA_NLS10
restart all instances
and now successfully enable DV at last!

Of course, afterwards ORA_NLS10 must be set again
srvctl setenv  database -d <DB_UNIQUE_NAME> -t "ORA_NLS10=<ORACLE_HOME>/nls/data/9idata"
and instances restarted once more.
