A hybird Notes/DB2 environment provides a requisition catalog on the Web. Client
browsers are connected to a GWA infrastructure including a first network dispatcher
and a virtual cluster of Domino.Go servers. The network dispatcher sprays out browser
requests among configured .nsf servers in virtual server cluster. Communications
from this virtual server cluster are, in turn, dispatched by a second network dispatcher
in a Domino cluster. External objects, primarily for a GUI, are served in a .dfs
and include graphic files, Java files, HTML images and net.data macros. The catalog
is built from supplier provided flat files. A front end is provided for business
logic and validation, as also is a relation database backend. HTML forms are populated
using relational database agents. A role table is used for controlling access both
to Notes code and DB2 data. Large amounts of data are quickly transferred using
an intermediate agent and window.
