Data Admin System Documentation - Hardware and Software Requirements - May 2008

This page describes the hardware and software requirements for both the end user's client computing environment as well as those for the backend server. The first section lists the high level requirements needed for both the client and the backend IBIS-PH Admin Application Server. Following that list, more detailed information is provided about each critical component. These requirements are left to be somewhat general as one server configuration does not fit all the various adopting agencies needs and are dependent on a variety of factors. The beauty of Java is that it is scalable and runs on virtually all modern operating systems and hardware platforms. Given the above information the requirements really are simply as listed below.

High Level Requirements

  • Client (Front End)
    • Modern fairly up to date internet browser (IE 5.5+, FireFox, Netscape 6+ etc.)
    • Computer hardware and operating system needed to run the above browser
    • Internet connection to the server(s) that host the IBIS-PH system(s)
    • Typical End User's Computer: 2Ghz Intel Pentium PC with 100GB hard drive, 512MB memory, DSL internet connection, running MS IE 6.0.x.

  • IBIS-PH Data Admin Application (Back End)
    • Java Development Kit (1.5+)
    • Java Application Server (Servlet Container 2.3+)
    • IBIS-PH Data Administration System Web Application
    • Any operating system that supports the above Java Application Server and JDK
    • Internet connection to the server(s) that host the IBIS-PH system(s)
    • SQL based RDBMS which has a JDBC driver and is setup for outside application connectivity
    • RDBMS user account which has privs to select, insert, update, and delete table data records.
    • Typical Server Computer: Dual 2Ghz Intel Pentium Xeon processors in a 1u rack mount case, redundant power supplies, (4) 18GB hot swappable Raid 0+1 hard drives, 2GB memory, T3 internet connection, Sun's J2SE JVM version 1.5, Apache Tomcat version 5.5, MS XP or Linux, MySQL RDBMS, both IBIS-PH View and Data Administration applications.

      Low End Server:

      Single 2ghz Intel Pentium IV or AMD Athlon CPU, 512MB of memory, 40GB hard disk, Linux or Windows98, Java J2SE JDK 1.5, Tomcat 5.5, and the IBIS-PH Data Administration Application and MySQL. This configuration will run the application just fine in a light load environment. It will not be as manageable nor as potentially reliable as a redundant hot swappable server but if cost is a factor and if testing or deploying into an environment that has a light load then this configuration will do the job.

      High End Server:

      Clustered multi-processor Sun or IBM server environment with a centralized SAN running many apps on a centralized IBM's Websphere Java App Server on MS-Windows XP Server or Unix etc. A configuration like this is on the other end of the price spectrum and can cost hundreds of thousands of dollars when considering hardware, commercial software, and the IT labor costs.

Front End Client Internet Browser Requirements

  • The IBIS-PH Admin System produces HTML 4 and utilizes newer Javascript techniques and object calls so a modern, up to date browser is required. The system has been heavily tested with MS Internet Explorer 6.x on Windows/Intel based hardware since it dominates the installed base of browsers. Netscape Navigator versions 6+, Firefox version 1+ have also been heavily tested and found to work. Opera version 7+ and IE 5.x have also been tested and found to mostly work (although there are some issues with CSS and the SVG plugin which is the next item discussed). IE on the Mac has been shown to be problematic. Other modern compliant browsers should work but have not been tested.
  • All Admin web pages require Javascript to be enabled. The pages have a mechanism to auto save changed data when navigating to another page.

Current Utah System

As of May 2005 Utah is running the Admin, View, and IBIS-Q applications on two different servers. The first hosts the View System, Data Administration System as well as the MySQL RDBMS with the other server hosting the IBIS-Q system (along with the SAS software and SAS datasets). In the past it has been on as many as four servers View and Admin on a Sun iPlanet box, Oracle on an IBM mainframe, and IBIS-Q/SAS on an HP-UX box. The View, Admin, and MySQL RDBMS portion of the system uses:
  • Compaq 257917-001 Proliant Model DL380 with redundant power supplies
  • duel 2.40GHZ Intel Xeon processors
  • 3GB RAM
  • (4) 18GB 15k ultra 320 SCSI's running raid 0+1 (and are hot swappable)
  • SuSE Linux operating system
  • Tomcat 5.5 web and Java application server

The server runs at about 10% utilization with an occasional peak of around 85%. It was purchased in 2004 for under $5,000.

NOTE: The entire IBIS-PH system (View, Admin, relational database, IBIS-Q, and SAS) is capable of being hosted on a single machine but is equally well suited for being hosted on many machines in a distributed environment. The single, minimalist server described above should provide acceptable performance for light to moderate loads. If using with the query system with everything on one box then more CPU and faster disk IO is highly recommend to handle the demands of SAS. If the system is distributed among several machines then a high speed LAN/WAN is also an important factor in overall system performance. Basically, better performance will be achieved with a faster and more powerful machine(s). However, the end user's experience is probably going to be determined more by the speed of the network connection between them and the server since most backend servers easily handle the minimal IBIS application load.

Data Storage

Data Storage Capacity for the IBIS-PH Data Administration System is not very large in light of today's high capacity disks. Utah's IBIS-PH Data Administration System currently uses approximately 1 gigabyte of storage space for the application, application server software, MySQL application, and the MySQL data tables.

Web Server

Web Server (if using as a front end to the Java app server e.g. IIS or Apache instead of the Java app server's built in web server). This is not required but can be used as a front end proxy to centralize web trending and to aid in network security. If this is desired then that servers hardware/software requirements would need to be considered (typically this is minimal). The web server must be able to handle/be configured/setup for proxy or forwarding/handling the requests/responses to/from from the Java application server which contains the IBIS-PH Data Administration System. Microsoft IIS and the Apache web server are two of the more common web servers that are capable of interfacing with a backend Java application server.

Internet infrastructure/connection

Internet infrastructure/connection for the server(s) that are hosting the IBIS system and any related web servers (any needed networking and proxy configurations as well as firewall configurations as required by IT infrastructure).

Java Web Application Server

  • Java web application server (Java HTTP servlet container). The best known free, open source packages include JBoss and Apache's Tomcat. Commercial packages include IBM's Websphere, Sun's SunOne (Iplanet), BEA's WebLogic, and many others. If using Tomcat see the Tomcat Setup document for tips on setting up Tomcat.
  • Java JDK version 1.5+. Installed and setup to be used by the Java application server.
  • Java J2EE JDK version 1.3+. Installed and setup to be used by the Java application server (if not already included as part of the Java application server).
  • Setup/configure the JDBC JNDI connection.
  • IBIS-PH View software package. This open application/system software must be deployed to the Java web application server. Most app servers have mechanisms to deploy a war file to their environment (For Tomcat this can be as simple as copying the "ibisph-admin_version_x_y.war" file to the tomcat/webapps directory and restarting or can be done using the Tomcat Admin system). If not Tomcat then you will need to consult with your system administrator.

Database Server

Utah currently uses a dedicated MySQL database which is located on the same server as the web application. In the past, the database was hosted on an IBM mainframe running Oracle. The application has also been tested to run on Microsoft's SQL Server.
