Preparing your HP-UX machine

This section includes information for setting up your operating system for WebSphere Portal with Cloudscape. Other components might require additional steps; see the product documentation for the specific components you want to install for information.

 

Configure HP-UX kernel settings before installing

To set kernel parameters, perform the following steps:

  1. Log into the host machine with superuser (root) privileges.

  2. Determine the physical memory, which know to avoid setting certain kernel parameters above the physical capacity:

    1. Start the HP-UX System Administration Manager (SAM) utility.

    2. Select Performance Monitors > System Properties > Memory.

    3. Note the value for Physical Memory and click OK.

    4. Exit from the SAM utility.

  3. Set the maxfiles and maxfiles_lim parameters to at least 4096. (The table below recommends 8000 and 8196, respectively. first edit the /usr/conf/master.d/core-hpux file, to allow the SAM utility to set values greater than 2048:

    1. Open the file /usr/conf/master.d/core-hpux in a text editor.

    2. Change the line," *range maxfiles<=2048" to "*range maxfiles<=60000"

    3. Change the line, "*range maxfiles_lim<=2048" to "*range maxfiles_lim<=60000"

    4. Save and close the file. Old values might be stored in the /var/sam/boot.config file. Force the SAM utility to create a new boot.config file:

      1. Move the existing version of the /var/sam/boot.config file to another location, such as the /tmp directory.

      2. Start the SAM utility.

      3. Select Kernel Configuration > Configurable Parameters. When the Kernel Configuration window opens, a new boot.config file exists.

        Alternatively, rebuild the boot.config file with this command: 

        # /usr/sam/lbin/getkinfo -b

  4. Set new kernel parameter values:

    1. Start the SAM utility.

    2. Select Kernel Configuration > Configurable Parameters.

    3. For each of the parameters in the following table, perform this procedure:

      1. Highlight the parameter to change.

      2. Select Actions > Modify Configurable Parameter.

      3. Type the new value in the Formula/Value field.

      4. Click OK.

    When WebSphere Portal and DB2 are installed on the same machine, some kernel values are higher than those shown in the table below. If you are using this configuration, refer to the following topics for more information:

    Typical kernel settings for running WebSphere Portal appear in the following table:

  5. Select Actions > Process New Kernel.

  6. Click Yes on the information window to confirm your decision to restart the machine.

    Follow on-screen instructions to restart your machine and to enable the new settings.
