ORA-45161: The backup piece size cannot exceed database DISK_RESERVED_SPACE

The database size is 30g and it was created  with 10g reserved space in RA:

SQL> conn rasys/welcome1
SQL> exec dbms_ra.add_db(db_unique_name=>'o11203',protection_policy_name =>'gold', reserved_space=>'10g');
SQL> exec dbms_ra.grant_db_access (db_unique_name=>'o11203',username => 'FD');




 

Documentation says about reserved_space: "Theamount of disk space that is guaranteed to be available for the protected database." 
As i understand it is minimum space quota guaranteed to the database.
So, the database IS ALLOWED to use more space !

But in real life well running backup may stumble on this threshold.
Demo:


[oracle@el01ac03-db01 rman_scripts]$ rman target / catalog FD/welcome1@zdlra | tee backup-FD-06041801.log

ZDLRA configuration parameters

The documentation says that rasys.RA_SERVER is the place of setting for RA. Look: But the actual settings treasury is rasys.CONFIG !...
