Figure 6-3 Pool configuration

After you define a connection pool, you may associate it with many different Integration

Objects. A copy of the connection pool becomes part of each application that includes one of

these Integration Objects, after the application is assembled in Application Integrator.

6.2.3 Information specified in a connection pool

A connection pool specifies several kinds of information, including:

 Data that allows your Host Publisher application to connect to a host. For Host Access

Integration Objects, this data includes the host name. For Database Access Integration

Objects, it includes the URL of the database.

 Whether connection pooling is enabled. Connection pooling is a method of keeping a

connection to a host open for many data transactions, instead of opening and closing a

connection with each new request. Connection pooling is designed to reduce the

response time between a request from a client browser and the display of the requested

information on a Web page. See 6.2.4, “Enabling and disabling connection pooling” on

page 146, for more information.

 Optionally

a user list. User lists contain information about accounts (user IDs) that a Host

Publisher application can use to access a host or database. Each entry in a user list

includes a user ID, password, and description of the account.

 Connect and disconnect macros (in Host Access only).
