Enable / Disable Table Lock

Table Lock locks a table to prevent DDL operations. Oracle Database permits DDL operations on a table only if the table can be locked during the operation. Such table locks are not required during DML operations.

Enable Table Lock
Choose Enable Table Lock to enable table locks, thereby allowing DDL operations on the table. All currently executing transactions must commit or roll back before Oracle Database enables the table lock.

Disable Table Lock
Choose Disable Table Lock to disable table locks, thereby preventing DDL operations on the table.
