In database tables
Note: If your data source uses one of the JDBC drivers bundled with ColdFusion MX 7,
ColdFusion MX can automatically create the necessary tables. If your data source uses the ODBC
Socket or a third-party JDBC driver, you must manually create the necessary CDATA and
CGLOBAL database tables.

In the operating system registry
Caution: Macromedia recommends that you do not store client variables in the registry because it
can critically degrade performance of the server. If you do use the registry to store client variables,
you must allocate sufficient memory and disk space.

of cached queries on the
server to [n] queries
Select this option by entering a value to limit the maximum number of
cached queries that the server maintains. Cached queries allow
retrieval of result sets from memory rather than through a database
transaction. Because queries reside in memory, and query result set
sizes differ, you must provide a limit for the number of cached queries.
