| System Requirements |  |
| This appendix supplies information about the web server system requirements and the desktop system requirements. Note In a Windows Terminal Server and Citrix environment, you cannot deploy Web UI. For more specific information, refer to http://pbc.infor.com. System requirements for the web server Required disk space The required disk space is calculated as follows.
Required disk space
Component | Required disk space (MB)
--- | ---
Web UI Code | 34
Infor ERP Online Help documents (for each language) | 40
Web UI form cache (for each package combination and for each language). Only applicable if you use Infor Enterprise Server 8.4.2 or lower. | 200
Report Viewer | 200
Total | 474
Note When the complete set of Infor ERP forms is exported and converted on the Web UI server system, an additional temporary size of 1 GB disk space is required. Extra disk space is also required when you convert 4GL reports to XML report designs. For details, refer to Infor ERP LN Development Tools 8.x Developer's Guide (U8883 US). Java servlet container The web server requires a Java servlet container that implements servlet API 2.2 or higher. The table below lists a number of servlet containers and application servers supported with Web UI. These servlet containers are supported on various Operating Systems. For information about the supported Operation Systems, refer to the servlet container’s documentation.

WebSphere v6 Note: Web UI supports WebSphere v6. However, the ERP LN Report Viewer requires Tomcat 5.5 or higher. For details, refer to Chapter 4, "Install ERP LN Report Viewer ". | IBM: http://www.ibm.com
Tomcat 5.5 or higher | Apache: http://jakarta.apache.org/tomcat/
J2SE v 1.4.2_13 (or up) | SUN: http://java.sun.com/
Java Runtime Environment Web UI requires Java 6. Version 1.6.0_23 is tested and delivered with the installer. Time zone data To accommodate daylight saving time changes in all time zones, the web server requires a Java Runtime Environment (JRE) containing the most recent time zone data. Depending on the type of your Web UI installation, the following actions are required:
Actions to ensure the JRE contains the most recent time zone data
Web UI installation type | Required actions
--- | ---
You manually installed a JRE, and manually deployed Web UI into a servlet container. | Complete one of the following steps: Install the latest JRE version. Run the Sun Java SE Platform TZupdater Tool. For details, refer to http://java.sun.com/javase/tzupdater_README.html.
You installed Web UI through the latest version of the Infor Enterprise Server Extensions installer. | No action is required, because the installation contains a JRE version with recent time zone data.
You installed Web UI through an older version of the Web UI installer, such as the Web UI 4.2 installer. | The installation contains a JRE with outdated time zone data. To correct this, complete one of the following steps: Run the TZupdater Tool. Uninstall the old Web UI version and install the latest Web UI version. Note: When you uninstall Web UI, you can decide to keep the files that contain the Web UI configuration settings. After the new installation, you can move these files to the appropriate folders under the new Web UI installation folder.
Note If no Java environment is installed on the Web UI server, you are prompted to install Java when you start Web UI. Java heap space Ensure the Java heap space is sufficient. If the heap space is too small, running multiple 'big' sessions in Web UI (inside a browser) can cause "OutOfMemoryError" messages. To prevent these errors, you can increase the heap space. Infor recommends a heap space of 128 Mb. Step 1. Check the allocated heap space Complete the following steps: In the system tray, right-click the Java icon and, on the shortcut menu, click Open <version number> Console. The Java Console starts. Type `s`. The system and deployment properties are displayed. View the "javaplugin.maxHeapSize" property. The displayed value is in Mb. For example: 96m means 96 Mb. Step 2. If necessary, increase the allocated heap space If the allocated heap space is less than 128 Mb, complete the following steps: Open the Windows Control Panel. Click Java. The Java Control Panel starts. Go to the Java tab. In the Java Runtime Environment Settings group, click View. The Java Runtime Environment Settings dialog starts. Perform this step for each row in the dialog. Double-click the Runtime Parameters column and enter the following value: `-Xmx128m -Djavaplugin.maxHeapSize=128m` Note If you perform an update of the JRE, a new entry is added to the list of JREs. After an update, you must add the same parameters for the new version. These settings are only effective if Web UI runs as an applet in a browser. They have no effect if Web UI runs as an application using Java Web Start. User limits (Linux) On a Linux web server you must set the following limits for the user who starts the web server:
User limit | Value
nofile (soft limit) | 65535
nofile (hard limit) | 65535
Set these limits in the /etc/security/limits.conf file. Example The web server is started by user root. You specify the following in the /etc/security/limits.conf file:
    root    soft    nofile  65535

    root    hard    nofile  65535
Environment variables DISPLAY On Linux/Unix-systems, the DISPLAY environment variable must be set to see the charts of Infor ERP LN 6.1. These chart images are generated on the web server. System requirements for the desktop For details on the software and hardware requirements for the client PC, refer to Infor ERP LN Web UI 8.x Sizing Guide (B0032 US). Additional requirements: 32-bits browser IE 7 or IE 8 (preferable), if Web UI runs in Companion Java 6, 32-bits, patch 22, if Web UI runs in Companion Related topics Prerequisites for the Infor ERP LN Server Prerequisites for using Infor Single Sign On |
