Planning for installation on z/OS

Use this task to prepare to install WebSphere® Application Server for z/OS® product code.

Before you begin

Print and review Creating implementation plans on z/OS. Assemble a team of people to install and configure the product. Be sure that the team has the skills needed to plan, install, and configure WebSphere Application Server for z/OS. See Skill requirements for more information.

About this task

You must completely install the product code for WebSphere Application Server for z/OS before you can set up an application serving environment. Obtain product code from IBM® in one of the following formats: Perform the tasks in this section before you install the WebSphere Application Server for z/OS product code. By planning your product code placement and naming, you can ease future product maintenance and migration tasks.

Procedure

  1. Make sure that the z/OS system on which you will install WebSphere Application Server for z/OS meets the hardware and software requirements. See z/OS driving system requirements for more information.
  2. Identify the software delivery option you will use. To review your product delivery options see IBM SystemPac or ServerPac or IBM Custom-Build Product Delivery Offering (CBPDO) for more information.
  3. Learn about WebSphere Application Server product data sets, and plan a naming convention. See z/OS product datasets for more information.
  4. Learn about WebSphere Application Server product directories, and plan a mount point convention. See Product file system for more information.
    Avoid trouble Avoid trouble: If you plan to install the application server on a z/OS system in which program control is enabled, when you log into a form-based web application you might receive the following error message in the system log file:
    ICH420I PROGRAM BBORSMCT FROM LIBRARY WAS.SBBOLD2 CAUSED THE ENVIRONMENT TO BECOME UNCONTROLLED.
    BPXP014I ENVIRONMENT MUST BE CONTROLLED FOR DAEMON (BPX.DAEMON)
    PROCESSING.
    If you receive this message, you should also see the errno2 code 151782063 in a RAS Trace for the servant:
    name --> errno value --> 157 --> 0x9d name --> errno2 value --> 151782063 --> 0x090C02AF
    
    The 02AF indicates that the program controlled bit is not properly set. The specified function is not supported in an address space where a load is done that is not program controlled.

    Although program control is enabled on the z/OS system, the program control extended control bits for the application server's native modules will not be enabled. To prevent or resolve this problem enable the program control bits for all of the native load modules in the SMP/E HTTP Server file system (HFS).

    1. Add the necessary attributes to the modules:
      cd SMPE_ROOT/usr/lpp/install_root/V7R0/lib/modules
      extattr +p *
      
    2. Add the attributes to the *.so files and bbo* files in the lib directory:
      cd SMPE_ROOT/usr/lpp/install_root/V7R0/lib
      extattr +p *.so
      extattr +p bbo*
    gotcha
  5. Decide whether to install the WebSphere Application Server Version 7.0 Optional Materials feature.

    This feature must be installed in order to install and use feature packs and other interim deliverables.

  6. Decide whether to install the DMZ Secure Proxy Server for WebSphere Application Server Version 7.0.

    The DMZ Secure Proxy Server must be installed in order to run a secure proxy server on a z/OS system that might not include the WebSphere Application Server for z/OS product.

What to do next

When you have finished the planning process, you are ready to begin installing the product. See Installing the product and additional software on z/OS.
