Configuring JDBC providers to use IBM Optim pureQuery Runtime to access DB2

Use this task to configure the application data source Java Database Connectivity (JDBC) provider to use IBM Optim pureQuery Runtime to access DB2® in a Java EE environment.

Before you begin

If you need to use multiple DB2 package collections, see the documentation about configuring pureQuery to use multiple package collections, before continuing with this task.

About this task

IBM Optim pureQuery Runtime makes use of DB2 packages. These packages consist of information for one or more SQL statements and are stored in the DB2 catalog. You must first run the wsdb2gen command on a JPA application to create the packages. The wsdb2gen command creates an XML file containing SQL statement information. This XML file must be included into the application Java archive (JAR) file. The DB2 bind command uses this file as input to create the DB2 package.

Attention: Read more about the DB2 JAR level compliance for IBM Optim pureQuery Runtime at the IBM Support Website: System requirements for IBM Optim pureQuery Runtime for Linux, UNIX, and Windows.

Procedure

  1. Update the application data source JDBC provider configuration to include the IBM Optim pureQuery Runtime JAR file. Either define an new JDBC provider or modify an existing provider to include the following JAR files. For more information, see the documentation about the JDBC provider settings and installing IBM Optim pureQuery Runtime.
    • pdq.jar
    • pdqmgmt.jar
  2. Using the DB2 bind command, bind the XML file to the database. This creates the DB2 packages. There are three ways to do this:
    • Use the wsadmin command. Refer to the information center topic on application management command group for the AdminTask object for more information.
    • Using the administrative console. Refer to the information center topic on SQLj profiles and pureQuery bind files settings for more information.
    • Using the DB2 bind command provided by Data Studio. Refer to the information center topic on the pureQuery Bind utility for more information.

What to do next

If you want to reconfigure the data source for JDBC, just remove the pdq.jar and pdqmgmt.jar from the class path.
