HP: Preparing your operating system

Prepare the operating system to ensure a successful installation.

Procedure

  1. Log in to the host server with superuser (root) privileges.
  2. Choose one of the following options to determine the physical memory, which you must know to avoid setting certain kernel parameters higher than the physical capacity:
    • HP-UX 11i Version 3 and later: Use the /usr/sbin/dmesg command.
    • HP-UX 11i Version 2 and earlier: Complete the following steps:
      1. Start the HP-UX System Administration Manager (SAM) utility with the /usr/sbin/sam command.
      2. Select Performance Monitors > System Properties > Memory.
      3. View 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 minimum value for maxfiles is 8000. The minimum value for maxfiles_lim is 8196.

    To allow the SAM utility to set values greater than 2048, edit the /usr/conf/master.d/core-hpux file.

    Note: If you are using HP-UX 11i Version 2, the /usr/conf/master.d/core-hpux file does not exist; instead, use the SAM utility to set the new kernel parameter values.
    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 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. Web Content Manager only: Use the ulimit -f command to set the maximum size of files that can be created. Set this value to be at least the size of the largest file you must upload to the content server.
    The command ulimit -f -1 removes any limit on file size.
  5. Complete the following steps to configure the HP-UX system kernel:
    1. Start the SAM utility.
    2. Select Kernel Configuration > Configurable Parameters.
    3. Repeat the following steps for each parameter in the table:
      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.
      Note: When HCL Portal and DB2® are installed on the same server, some kernel values are higher than the values shown in the table.
