Deploy data access applications

Before you deploy a data access application into the WAS environment, first make sure that the appropriate database objects are available. This action includes creating and configuring any databases or tables required, setting necessary configuration parameters to handle expected load, and configuring any necessary JDBC providers and data source objects for servlets, enterprise beans, and client applications to use.

Consider the following before you deploy a data access application:

• Create a database and the tables that are required by your application.
  You must perform this step it your database configuration does not already exist.

  • If your application uses entity enterprise beans to access the data, you can create the tables with the data definition language (DDL) that is generated from the enterprise bean configuration. For more information, see Recreating database tables from the exported table DDL.

  • If your application does not use entity beans, use your database server interfaces to create the tables.

  • See Available JDBC providers for DB2 UDB for iSeries data source requirements.

• Migrate a Version 4 data access application to Version 5 in the Migration topic, if applicable.

• Administer JDBC providers and data sources in the Administration topic.
  If your data access application contains a Web application or an enterprise bean (EJB) application that uses connection pooling to access a relational database, create a JDBC provider before you deploy your application.

• Configure WAS to access databases.
  You must configure your application server to access databases if your enterprise application contains an application client that accesses a relational database.

• Consider Security of lookups with component managed authentication.
  If an external Java client (stand alone client or server from other cells) needs to get a connection, it must assume responsibility for the authentication data.

See Administer applications in Administration for more information about deploying your data access application.
