DDL lock

DDL lock is also known as dictionary lock. DDL locks protect the structure of schema objects, for example, the definitions of tables and views. A data dictionary (DDL) lock protects the definition of a schema object while an ongoing DDL operation (CREATE, ALTER, DROP) acts on or refers to the object.
