Empty Database File

If the database file is empty, the required database file structures to support partitioning can be created in two ways.

Calling the setPartitioned method on the schema-defined DbFile instance associated with the database file, as shown in the following example.
```
begin
    beginTransaction;
    Customer.getDbFile.setPartitioned(true);
    commitTransaction;
end;
```
Executing the JADE Database Administration utility (jdbadmin) with the action=MakePartitioned action, as shown in the following example.
```
jdbadmin path=c:\jade\system ini=c:\jade\jade.ini action=MakePartitioned file=customer
```

When partitioning is enabled on a new file, the required partition structures are created when the file is first instantiated. Partitioning can be enabled on an existing empty non-partitioned file, in which case the non-partitioned file is deleted first.
