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.
