Updating the special resource database

Each resource is created with this structure:

 Order (priority) in which the scheduler uses the data: ────────────────|
                                                           Where?       │
                                                           CP RD        │

The interval and default (header) data is maintained in the resource database (RD) and copied to the current plan (CP), where you can change it with the MCP panel Resource Monitor. The overriding (global) fields are present only in the current plan.

The header has default values that are always used to complete any missing fields in the intervals. For example, suppose that you have created a special resource TAPES with these default values:


	Quantity	Availability	Connected workstations
Defaults	8	Y	CPU1 STC1

and you specify intervals with some values specified (shown in bold). The missing values are completed from the default (shaded) values:


Day and time	Quantity	Availability	Connected workstations
STANDARD 08.00 to 22.00	6	Y	CPU1 STC1
SATURDAY 00.00 to 24.00	8	Y	CPU1
SUNDAY 08.00 to 10.00	8	N	CPU1 STC1

STANDARD specifies the days of the week that are not otherwise specified (in this case, Monday to Friday). Days and times not covered by the intervals (such as Monday at 01.00 and Sunday at 01.00) take the default values of 8 drives available on the CPU1 and STC1 workstations. The STC1 workstation cannot use the TAPES resource on Saturdays. No workstation can use the resource (it is unavailable) between 08.00 and 10.00 on Sundays.

Do not confuse the default availability and quantity with the overriding (or global) values, which exist only in the current plan. When you alter the quantity with the SRSTAT command, for example, you always change the overriding quantity. If you use the MCP panel, you can change both default and overriding values.
