Download and Installation Instructions

Installing and using WebLogic Platform 8.1 SP5 on HP-UX 11i V2 (11.23) on Itanium requires the following:

To install WebLogic Platform 8.1 SP5 on HP-UX 11i V2 (HP-UX 11.23), complete the following procedure:

  1. Go to the following HP Web site:

    Download and install HP-UX SDK

  3. Go to the BEA Downloads site ( and download the appropriate package installer:
  4. Install WebLogic Platform 8.1 SP5 or WebLogic Server 8.1 SP5 for HP-UX 11i V2 using the instructions provided for .jar installation files, as described in Installing WebLogic Platform.
  5. For example, if you are installing in console mode, enter the following on the command line:

    $ java -jar pj_platform815_generic.jar -mode=console

    For detailed instructions, see "Starting Console-Mode Installation on UNIX Systems" in Installing BEA WebLogic Platform:

    Note: When using an Asian version of an installer (such as an installer for Japanese, Korean, or Simplified Chinese), you need to increase the maximum heap size to 256 MB by specifying the -Xmx256m argument on the command line. For example, if you are using a Japanese installer, enter the following command:
    $ java -Xmx256m -jar pj_platform815_ja_generic.jar -mode=console

  6. Set the WL_HOME variable to the directory in which you installed WebLogic Platform, and export WL_HOME:
  7. $ export WL_HOME=/your_installation_directory/weblogic81
  8. Set the correct execution modes on the contents of the weblogic81/server/bin and weblogic81/server/lib directories:
  9. $ chmod +x $WL_HOME/server/bin/*
    $ chmod -R +x $WL_HOME/server/lib/hpux11/*


Recommended Kernel Parameter Settings

The HP-UX 11i V2 (11.23) default value for maximum threads per process (max_thread_proc) is 64, which may be too low for WebLogic Server and many Java server applications in general. When the value is too low, WebLogic Server may have problems starting up. Therefore BEA recommends that you use the maximum kernel setting for the max_thread_proc parameter.

The following table provides some examples.

Table 3-2 Recommended HP-UX 11i V2 (11.23) Kernel Settings


Old Value

New Value





Maximum threads per process




Maximum data segment size




Soft file limit per process




Total number of threads in the system




Maximum number of processes


BEA also recommends that you use tools such as HPjconfig to verify that the values of your tunable kernel parameters are optimal. For more information about HPjconfig, see:
