Industry Standard Benchmark Tests

This test type allows you to create load scenarios from one of the following industry standard benchmark tests: TPC-C, TPC-E, TPC-H, AS3AP, Scalable Hardware, TPC-B, or TPC-D. Each of these tests includes the steps to create/load all the required benchmark objects needed to execute the standard benchmark workloads. These synthetic workloads can be used when no real-world data is available to import for database load testing.

This test type also allows you to create a workload using the Benchmark Factory Replication test.

For more information, including a description of each of the standard benchmark tests included in Benchmark Factory, see Overview of Benchmark Testing.

Replication Benchmark Test

The Replication benchmark test is a unique test developed by Benchmark Factory for testing replication in applications such as SharePlex.

This test allows you to create customized database objects, as well as a customized workload, in order to produce a repeatable database change rate and history (for example, Oracle redo logs) that can be used to test replication strategies. This test can also be used to create a model of your database and workload in order to help demonstrate replication performance.

While this benchmark was designed for testing and evaluating replication strategies and functionality in SharePlex, it can also be used to test other database replication products as well.

The following options can be customized in the Replication benchmark test:

  • The number of tables in the test
  • The number of columns per table and the column types (data types)
  • The percentage of each column type (data type) in all tables, for example, 40% INT, 20% VARCHAR(255), etc.
  • The percentage of each statement type (insert, update, delete), as well as the number of statements per commit (transaction)

Capture and Replay a Workload

Capture/Replay tests allow you to capture and then replay a workload, or replay an existing capture from a trace file, database repository, text file, or output from another Quest Software tool.

Select one of the following topics for more information:

Capture and Replay Oracle Workload

Benchmark Factory allows you to capture Oracle workloads, then replay those workloads to view transactions and response times.

In Benchmark Factory, use one of the following workflows to capture an Oracle workload:

  • New Job Wizard—Use the New Job Wizard (File | New) to guide you through the steps of setting up and capturing the workload. Then add the captured workload to your new job to run it immediately or at a later time.
  • Capture Scenario Wizard—Select Tools | Capture Workload to open the Capture Scenario Wizard.

Note: This feature is not available in the freeware version of Benchmark Factory.

See also, Considerations When Performing an Oracle Capture and Replay.

To capture an Oracle workload

  1. Select File | New to open the New Job Wizard.
  2. On the Database Under Test page, select the database to test.
  3. Then click .
  4. On the Workload page, select Capture/Replay Test from the drop-down list.
  5. Then select the Capture and Replay Oracle Workload option.
  6. Click .
  7. On the Replay Workload page, click Perform New Capture. The Capture Scenario Wizard opens and the New Job Wizard closes.

    Tip: You can also create a new capture using the same settings as an existing capture project. In the Captures tab of the Benchmark Factory console, right-click a capture and select Repeat Capture.

  8. Capture Scenario Wizard. In the Capture Scenario Wizard, enter connection information for the database from which you want to capture a workload. For more information, see Create Oracle Connection. Click Next when finished.

  9. Select Capture Method. On the Select Capture Method page, select a capture method to use. Review the options below. Click Next when finished.

    Capture using Oracle Trace files

    Captures workloads using trace files written to a specified server directory.  These files are captured at the session level.

    Note: The Trace file capture method is not available for Oracle connections that use Real Application Clusters (RAC).

    Capture using FGAC (Fine-Grained Access Control)

    Captures workloads using the Oracle Fine-Grained Access objects that capture activities at the database table and view levels.

    Tablespace for capture table—Allows you to select the required tablespace for Fine Grained Access captures.

    Note: The FGAC capture method is enabled only if the feature is available in the target database.

  10. Apply Privileges. If the user does not have the required privileges to do the capture, the Apply Privileges page opens. Enter the credentials of a DBA-type user account that can apply the necessary privileges. Click Next when finished.

    Note: To view the missing privileges necessary for this user to perform the capture process, click the View/Save Script button and review the script.

  11. Directory Settings. On the Directory Settings page, specify an Oracle server-side directory in which to place the capture files. Also, specify the capture directory from which Benchmark Factory will replay the files. Review the following for additional information:

    Click Next when finished.

    Capture Name

    Enter a name for the capture, or use the default. This name is used for the sub-directory where the capture files are stored in the Capture Directory you specify.

    Note: Only alpha and numeric characters and the underscore (_) are permitted. The name must begin with a letter.

    Database Server Directory

    Specify an Oracle server-side directory where Benchmark Factory should place the capture files. Specify the path as the server sees it.

    Note: You can specify a network directory here. Enter the full network path to the network directory. The database service must be able to access the network directory. In a Linux environment, a local directory must be mounted to the network location.

    Capture Directory

    Specify a directory where Benchmark Factory will look for the capture files to replay. Do one of the following:

    • Manual transfer: Specify a client-side directory and then manually transfer the capture files to this location.
    • Shared directory: Specify the same Oracle server-side (or network) directory you specified in the preceding field. However, enter the path as the client computer sees it.

      To use this method, you must first map a drive on the client computer to the Database Server Directory (Oracle server-side or network directory). Then, browse to and select that mapped drive.

    Selecting a shared directory: The shared capture directory can be on the database server as a local directory or on a network file server as a local directory. Either location must be accessible by the Benchmark Factory client computer (Windows network share, Samba, or NFS). A network file server is the preferred location for the following reasons:

    • This minimizes total network I/O required for capture and replay.
    • The shared directory can be placed on an I/O subsystem with sufficient I/O bandwidth to handle both the concurrent I/O writing and the cumulative size of the trace and export files.

  12. Reporting method. On the Reporting Settings page, select the performance reporting method to use. Review the options below. Click Next when finished.

    Reporting Method

    Select a performance collection and reporting method.

    • AWR—If this option is selected, Benchmark Factory uses the optional Oracle Enterprise Manager (OEM) “Diagnostic Pack” Automatic Workload Repository (AWR) to collect database wide performance statistics, collect before and after workload capture, replay AWR snapshots of database-wide performance statistics, and generate a differences report between the capture and replay results.

      Note: A valid licenses is required to use the optional OEM Diagnostics Pack.

    • Statspack—If this option is selected, Benchmark Factory calls the Oracle “Stats Pack” utility to create a performance data repository, collect before and after workload capture, replay Stats Pack snapshots of database-wide performance statistics, and generate a different report between the capture and replay results.

      Note: "perfstat" is the default password.

    • ADDM—Select to instruct Benchmark Factory to use performance analysis information from the Oracle Automatic Database Diagnostic Monitor (ADDM).
    • None—If this option is selected, no reports are generated.

  13. Capture Scope. The Capture Scope page allows you to select schemas for capture. You can select the entire database or use the list to select specific schemas. Review the options below. Click Next when finished.

    Capture activity for entire database

    Captures activity for the entire database, but not for built-in accounts.

    Capture only activity upon selected owner's database objects

    Captures only the data of the selected database objects. This option allows you to select individual schemas for capture.

    1. To select database objects, move the desired schemas to the right pane.
    2. To specify auto-included schemas, click one or both of the following buttons:
      • Roles—Opens the Auto Included Roles dialog which displays the roles that can access the objects in the schemas in the Selected Schemas column. Select which roles to include or exclude.
      • Schemas—Opens the Auto Included Schemas dialog which displays schemas that can access the objects in the Selected Schemas. Select which related schemas to include or exclude.

  14. Export Scope. The Export Scope page allows you to specify whether or not to export the database objects and data required to replay the workload on the same data snapshot. Review the options below. Click Next when finished.

    Perform export as part of capture process

    Select to instruct Benchmark Factory to export the objects selected on the previous page (Capture Scope). The export is performed during the capture procedure.

    Note: If you selected to capture activity for the entire database, exporting the entire database can require significant time and space.

    Include export of related schemas—Select to export the auto-included schemas selected on the Capture Scope page.

  15. Filter Settings. (Optional) The Filtered Settings page allows you to add filters to exclude activity from the capture.
    • To add a filter, click Add. Then specify parameters for the filter. Click Next when finished.

  16. Capture Thresholds. Benchmark Factory allows you to specify limits for CPU usage and free space during a capture. If levels exceed the values you specify, the capture process is stopped.

    Benchmark Factory displays the current values to help you determine the best thresholds to specify. Review the options below. Click Next when finished.

    Stop capture if CPU percentage exceeds Enter a percentage. If CPU usage exceeds this value, Benchmark Factory stops the capture process.
    Stop capture if disk/tablespace free space falls below Enter a value for free space in MB. If the amount of free space falls below this level, Benchmark Factory stops the capture process.
  17. Capture Control. Use the Capture Control page to specify when to start the capture.

    You can start the capture immediately after finishing the wizard, or you can schedule the capture. Review the options below. Click Next when finished.

    Start Capture/Export

    Immediately—Select to start the capture process immediately.

    Scheduled (via database schedule)—Select to schedule the capture process. Then specify a date and time based on the server time.

    Capture Automatically

    Stop After—Use the sliders to specify a duration for the capture process. The default is 30 minutes.

  18. Start the capture. The Finish page provides capture specifications. To start the capture (or enable the schedule), click Capture.

  19. Capture Status. The Capture Status window opens providing export or capture status and process details.

    Immediate capture: If you selected to start the capture immediately, the Capture Status window displays information about the capture process, such as the status of the export process and the number of sessions captured.

    • Click the Click here for details link to view more-detailed information during the export or capture. You can view which objects are exporting or which session/user is currently being captured and the total number of sessions captured.
    • Click Settings to review the capture description.

    Scheduled capture: If you scheduled the capture process, leave the capture wizard open to run the capture at the scheduled time.

  20. Transfer and process files. When the workload capture is finished, the Oracle capture files are processed.
    • If you stopped the capture before it was finished, Benchmark Factory prompts you to process the files.
    • If you specified a client-side directory (instead of a shared directory) as the Capture Directory (directory from which the client replays the capture), BMF prompts you to transfer the capture files to your client-side directory now. Copy or move the trace/xml and export (DMP) files from the directory where they were generated (Database Server Directory) to the client-side Capture Directory. Place the files into the existing capture-named sub-directory. After transferring the files, click OK in the message box. BMF then processes the necessary files and updates the project file.

      Optionally, if you want to transfer the files at a later time, click Cancel.

  21. Click the Click here for details links to review the export and capture processes. Close the Capture Status window when finished. You can open the Capture Status window again from the Captures tab in the Benchmark Factory console. In the Captures tab, right-click a capture and select View Status.

Considerations When Performing an Oracle Capture and Replay

Consideration Description
Trace file capture and replay times (AWR) might not match

When using trace files as the capture method, you could find that the replay time as reported by the AWR does not match your specified capture time.

Benchmark Factory trace method only captures sessions that are initiated after the capture starts. If there is a lag between when the capture starts and when the first session is captured, this lag is reflected by the mismatched times.

Oracle Enterprise Manager TPS results If you choose to collect database wide performance statistics from the AWR, the TPS results from Benchmark Factory and Oracle Enterprise Manager may not match. This is because Benchmark Factory displays TPS for the workload, while OEM displays TPS for all the work the server is doing.

Notes:

  • Database objects created by Benchmark Factory for the capture process are automatically dropped after the capture is finished.
  • You can manage your existing capture projects from the Captures tab in the Benchmark Factory console.
