MUF_OPTIONS (MFO)

This table contains the general startup options that existed before Version 12.0. For information about newer startup options, see the MUF_CONFIG (MCF) section. Most MUF startup information is available but not all. Options which allow more than one occurrence are in other tables, such as the Accounting table or the CA Datacom products table. This table has only one row. Some of the fields are changeable, and the values reported are the current value at the time this row is read. An example is any of the FLEXPOOL fields. For these changeable fields, the value at the MUF startup is not available. CA Datacom/DB takes the liberty of rounding some of the buffer sizes up to doubleword or other boundaries. Expect this possibility in your reporting. A full description of these fields is contained in the section on modifying Multi-User startup options in the CA Datacom/DB Database and System Administration Guide.
