Use the IBM Systems Workload Estimator to predict the capacities and resource requirements for
WebSphere Commerce Payments.  The Estimator allows you to predict a standalone WCP environment
or a WCP environment associated with the buy visits from a WebSphere Commerce estimation.  Work
with your marketing representative to utilize this tool.  You’ll find the tool at:  

Workload Description:  The PayGen workload was measured using clients that emulate the payment
transaction initiated when Internet users purchase a product from an e-commerce shopping site.  The
payment transaction includes the Accept and Approve processing for the initiated payment request.
WebSphere Commerce Payments has the flexibility and capability to integrate different types of payment
cassettes due to the independent architecture.  Payment cassettes are the plugins used to accommodate
payment requirements on the Internet for merchants who need to accept multiple payment methods.  For
more information about the various cassettes, follow the link below: 

Performance Tips and Techniques:

1. DTD Path Considerations:  When using the Java Client API Library (CAL), the performance of the

WebSphere Commerce Payments can be significantly improved if the merchant application specifies
the dtdPath parameter when creating a PaymentServerClient.  When this parameter is specified, the
overhead of sending the entire IBMPaymentServer.dtd file with each response is avoided.  The
dtdPath parameter should contain the path of the locally stored copy of the IBMPaymentServer.dtd
file.  For the exact location of this file, refer to the Programmer's Guide and Reference at the
following link: 

2. Other Tuning Tips:  More performance tuning tips can be found in the Administrator’s Guide under

Appendix D at the following link: 

3. WebSphere Tuning Tips:   Please refer to the WebSphere section in section 6.2, for a discussion on

WebSphere Application Server performance as well as related web links.
