The Oracle Hints feature is enabled with this variable. Set A-ORA-HINTS to 1 (default) to turn on the feature. The default is 1, or on. To turn off the feature, set it to 0. Hints can improve runtime performance significantly in some situations.
Note that keys must use the ACUCOBOL-GT naming convention for naming indexes in the database to this function. For example, the primary key on the file ftest would be named iftest_0.
Oracle hints can improve database performance considerably by 'strongly suggesting' to the oracle query optimizer that it uses a given index to process a query.
While the default value is "1", this configuration variable can also take values of "Yes," "No," "True," "False," "On," or "Off."
