Summary:  IBM® InfoSphere® Optim™ Query Capture and Replay (IOQCR) 1.1 for Linux®, UNIX® and Windows® enable an organization to create a production-like data application test environment where changes can be tested and tuned before being deployed into production. InfoSphere Optim Query Capture and Replay captures all of the application workload running against a production database and replays it against a test database without the need to replicate the entire application infrastructure. It not only replays both dynamic and static SQL, but also reproduces the number of client connections and their properties, the timing and order of execution, transaction boundaries and isolation levels, and many other critical features of workload execution. The result is a much closer approximation of production workloads and greater confidence that when changes are deployed, they will not disrupt production.

Web console

By default, no login is required to access the InfoSphere Optim Query Capture and Replay web console. However to support multiple users and configure the console for user authentication, a repository database must be defined, as shown in Figure 4.

Task launcher

The Task launcher is the first page that is displayed. This page provides quick launch links for all the stages of the capture replay workload process stages. The key tasks and the getting started tasks can also be accessed from the Openmenu.

Key tasks

This provides links to all the main tasks to manage a capture and replay workload life-cycle as shown previously in Figure 4.

  • Capture: Capture a DB2 workload opens the Capture dialog where required information can be specified to create a new workload to capture traffic on a DB2 database.
  • Transform: Transform a captured DB2 workload opens the Transform Dialog which enables transformation of a captured workload to a replay-ready workload.
  • Replay: Replay a DB2 workload opens the Replay dialog. Here you can select a replay-ready workload and replay it on a DB2 database.
  • Guardium web console: Open the Guardium web console link will allow you to log on to the Guardium web console. Here you can configure the S-TAP agent for the capture and replay database.

Getting started

The Databases tab provides links to all the administration/setup tasks, as shown in Figure 5.


Figure 5. Monitored database screen
Monitored Database Screen
  • Help: "Steps for capturing and replaying DB2 workloads" opens help with detailed instruction on how to use InfoSphere Optim Query Capture and Replay web console.
  • Add Databases: “Add database connections” opens the databases tab which allows you to configure database connections. All the databases used during the workload life-cycle are defined here. An option to add a new database is also available in the Capture and Transform dialogs.
  • Manage Privileges: Manage capture and replay database privileges opens the Manage Privileges tab. In order to perform the various tasks in the workload life-cycle, a user ID with privileges to perform the corresponding task must be specified.

    The Enable and Disable tab as shown in the Manage Privileges page in Figure 6 lists the privileges that are available for a selected database.



    Figure 6. Manage privileges – enable and disable

    The privileges of database users/groups/roles for the selected database can be managed in the Grant and Revoke tab as shown in the Figure 7. Users with appropriate privileges can grant/revoke permissions to other users.

This panel provides links to resources that provide more information about the InfoSphere Optim Query Capture and Replay product shown previously in Figure 4 in the section marked as 3 on the right bottom corner.

Open menu

You can click Open Menu at the upper left corner of the web console to access links to all the key tasks that are accessible from the Task Launcher. The menu provides a few additional links, including the following.

  • Capture and Replay: This opens the Capture and Replay page which lists existing workloads in the SQL Workloads tab and provides buttons to open the dialogs that are used to create the stages of the capture and replay process life-cycle, including Capture, Transform, and Replay and Report, as shown in Figure 9.
