1 Installing the XML Accelerator Introduction What is this chapter for? Who should read it? What is being installed? This document explains the prerequisites and how to install the XML Accelerator. This is an advanced install guide for system administrators only. Casual users should consult their support group before continuing. What is being installed? The SAP XML Accelerator GUI which allows the user access to the Converter and the Adapter tools.
Prerequisites What is needed before the install can begin? This chapter will detail the software and hardware that the GUI depends on and where to find it. Hardware The XML Accelerator software stack and GUI depend on the installation of the XML Accelerator board. This must be installed and correctly configured in the PI system before continuing. NOTE: The converter component of the XML Accelerator GUI does not require the hardware to be installed, the Adapter GUI does, however.
System Installation Instructions 1. Install your server by using the server specific installation instructions. NOTE: The server is factory configured with the following options: • SUSE SLES10 is factory installed on the XML Accelerator. Any operating system installation steps should be omitted. • The XML Accelerator is factory configured with a default processor and memory configuration.
NOTE: An example would be /sapmnt//exe/jvm/linuxx86_64/ dapjvm_5.1.015/sapjvm_5. e. f. 7. SAP Instance: A list of SAP instances is displayed. Choose which SAP instance is to be used by the HP XML Acceleration Software. SAP Profile: A list of SAP profiles is displayed. Choose the profile for the SAP instance that will be using the HP XML Acceleration Software. Add the following to the JVM(s) classpath using the SAP config tool: • //lib/tarari_xtr_load.

2 XML Accelerator Administration Introduction What is this section for, what is the SAP XML Accelerator GUI, what kind of GUI is it? What does the GUI allow me to do? This section is for users of the HP XML Accelerator For NetWeaver PI. It is a guide to the administration functions and use of the browser for the Converter and Adapter components of the system. . What form does the GUI take? The GUI is a web based interface that is hosted by the same server that PI is installed on.
3 Using the HP XML Converter for SAP NetWeaver PI The HP XML Converter for SAP NetWeaver PI optimizes SAP JAR files to run faster during the XML conversion process. The SAP NetWeaver technology platform is the technical foundation for all SAP applications. SAP NetWeaver provides the development and runtime environment for SAP applications. It can be used to develop custom applications and to integrate these applications with other applications and systems.
3. Save the message mapping JAR file by clicking the button to the right of the field Is Byte Code Available?, as shown in the following figure: Converting SAP Mappings To convert SAP mappings to run faster on the adapter, click the Convert tab on the main screen, if necessary. The following window appears: To convert and optimize an SAP JAR file, follow these steps: 1. Click the Browse button to the right of the Mapping jar-file field and find the JAR file you want to convert.
3. 4. (Optional) Select Overwrite existing jar if you want the new converted JAR file to overwrite the name of a previously converted file. (Optional) Select a different Transactions option. The HP XML Converter identifies transaction processing in message mappings, which enables mappings to be executed more efficiently at runtime. (Transactions are defined as repeated subdocuments nested in an enclosing document.
Testing a Compiled Mapping File Follow these steps to test a compiled mapping file created with HP XML Converter for SAP NetWeaver PI. 1. Click the Test tab. The following window appears. 2. 3. 4. 5. In the Input Document field, enter the name of the XML file to use for the test. Alternatively, click the browse button to the right of the field, and select an XML file. In the Output Document field, enter a full pathname for the output file from the test.
4. Select the accelerated mapping class from the newly imported archive. The Operation Mapping is now ready for use with the accelerated mapping class. NOTE: The Software Component Version that contains the Imported Archive associated with the accelerated mapping class must list the Software Component Version containing the XTR runtime library as an Underlying Software Component Version.
4 Using the HP XML Adapter for SAP NetWeaver PI The HP XML Adapter application is the runtime environment that enables you to use the HP XML Accelerator for SAP NetWeaver PI with SAP Graphical Mappings generated by the Converter (see Chapter 3 (page 10)) and XSLT. With the use of the Adapter application, PI is run normally and no code or operational changes are necessary to accelerate the execution of mappings.
Loading and Unloading the Driver IMPORTANT: The driver should not be unloaded or loaded while SAP is running. Normally, the driver is loaded and the XML adapter is in Online mode when you start the HP XML Adapter for SAP NetWeaver PI. To unload the driver, follow these steps: 1. Select Offline as the System Mode. The Unload button is enabled. 2. Click Unload. The status changes to Driver is unloaded and the Unload button changes to Load.
of the tab. The following sections briefly describe the type of information returned for the various diagnostics categories. Board Info Diagnostics Most of the Board diagnostic information is self-explanatory. Bus lanes indicates the number of PCIe lanes on the board. Memory Diagnostics The Memory diagnostics verify that memory is installed, display the amount of memory, and display the results of a memory test.
