Assigns the named row cache as the default for all storage areas
    in the database. All rows stored in an area, whether they consist
    of table data, segmented string data, or special rows such as
    index nodes, are cached.

    You must create the row cache before terminating the CREATE
    DATABASE statement. For example:

    SQL> CREATE DATABASE FILENAME test_db
    cont> ROW CACHE IS ENABLED
    cont> CACHE USING test1
    cont> CREATE CACHE test1
    cont>    CACHE SIZE IS 100 ROWS
    cont> CREATE STORAGE AREA area1;

    You can override the database default row cache by either
    specifying the CACHE USING clause after the CREATE STORAGE AREA
    clause or by later altering the database and storage area to
    assign a new row cache. Only one row cache is allowed for each
    storage area.

    If you do not specify the CACHE USING clause or the NO ROW CACHE
    clause, NO ROW CACHE is the default for the database.
