Its a display thing in the EM, 50 databases all in lower case, someone had created a database in uppercase so in a tidy up operation I was asked could I change the case to lower. no problem, I'll use nid
SQL> select name from v$database;
NAME
---------
JUPITER
startup force mount and use nid to rename the database
nid target=sys dbname=jupiter setname=yes
get error
NID-00144: New name for database JUPITER is the same as current name JUPITER
hmm, ok, maybe try in double quotes
nid target=sys dbname="jupiter" setname=yes
same error
NID-00144: New name for database JUPITER is the same as current name JUPITER
Is there some trick to this without having to recreate database from controlfile?
