An OLAP DML option is a special type of analytic workspace object that specifies the characteristic of some aspect of how Oracle OLAP calculates or formats data or what Oracle OLAP operations are activated. Some options are read-only, while others are read/write options for which you can specify values. Read/write options have default values.
You can use the SET (=) command to retrieve the value of an option into a predefined variable and to specify a new value for a read/write option. Use the SHOW command to display the value of an option.
