Note:

Oracle does not recommend using identifiers for Oracle AI Database object names that must be quoted. While the use of quoted identifiers may be valid as names in some command-line tools or in SQL statements, such as CREATE DISKGROUP "1DATA", the names may not be valid when using other tools that manage the object.
