Tuning Performance
This topic describes how to tune performance in a BEA Liquid Data for WebLogicTM deployment. It includes the following sections:
In a production environment, Liquid Data performance is generally measured by the speed with which queries are processed and results are returned. This topic describes general guidelines for performance and, where possible, provides specific guidelines for tuning a Liquid Data deployment.
In addition to the material described in this topic, you can refer to the following documentation to tune WebLogic Server and WebLogic Integration performance:
Where to Begin
This topic describes where to begin tuning a Liquid Data deployment. It contains the following sections:
Checking the System Configuration
Before you begin to investigate how to tune Liquid Data performance, make sure that the system on which Liquid Data runs is reasonably configured.
Tuning Queries
In addition to the system configuration, Liquid Data performance is greatly affected by the query design, as described in Query Performance Factors. Therefore, make sure that the queries running on the Liquid Data server are reasonably designed:
Liquid Data Performance Factors
Many factors influence overall Liquid Data performance. Certain factors, such as query design, are within the scope of Liquid Data's control, while other factors, such as data source processing speed, are outside the scope of Liquid Data control. This topic identifies the main factors that can affect Liquid Data performance. It includes the following sections:
Liquid Data performance depends on the way queries are designed and configured for execution. The following query factors affect Liquid Data performance:
In general, Liquid Data performance depends on the speed at which the data source host system is able to process query requests and return results. Performance Factors for All Data Sources The following data source factors affect Liquid Data performance:
Performance Factors for Data Source Types The following table describes the most important performance factors for each supported data source type:
This section describes performance factors associated with the Liquid Data server, including the host server hardware, clustering Liquid Data servers, tuning threads, tuning WebLogic Server, and tuning WebLogic Integration. The most important factor is running Liquid Data on a very fast server machine with the maximum amount of available memory. For general information about platform performance, see Tuning Hardware, Operating System, and Network Performance in BEA WebLogic Server Performance and Tuning. This section describes the following platform performance factors:
General Platform Performance Factors
The following general performance factors are associated with a Liquid Data deployment:
WebLogic Server Performance Factors Liquid Data performance is affected by WebLogic Server performance. The WebLogic Server documentation provides a detailed suggestions for monitoring and tuning run-time performance. For detailed information, see BEA WebLogic Server Performance and Tuning in the WebLogic Server documentation. The following table provides a summary of tuning factors, which are described at length in the WebLogic Server documentation:
Liquid Data Host Server Machine Faster hardware (storage, memory, and CPU throughput), large capacity storage (for caching and disk swapping), and for the Liquid Data server host machine generally provides higher performance. The following performance factors are associated with the host server machine:
WebLogic Integration Performance Factors If Liquid Data is deployed with WebLogic Integration, then WebLogic Integration performance might affect Liquid Data performance, depending on how the two components interact. The WebLogic Integration documentation provides a detailed suggestions for monitoring and tuning run-time performance. For detailed information, see Tuning Performance in Deploying Solutions in the WebLogic Integration documentation. The following table provides a summary of tuning factors, which are described at length in the WebLogic Integration documentation.
Monitoring Liquid Data Performance
This section describes how to monitor Liquid Data performance. It includes the following sections:
For detailed information about monitoring resources for the Liquid Data Server, see Monitoring the Server in the WebLogic Server Administration Guide.
Monitoring Guidelines
When monitoring Liquid Data performance, consider the following guidelines:
Using the Administration Console to Monitor Performance
You can use the Administration Console to monitor performance on a Liquid Data server, including the following areas:
For detailed information about using the Administration Console to monitor server performance, see the following topics in the WebLogic Server documentation:
