Known Issues

  1. The HP-UX 11.0 V2 (11.23) default value for maximum threads per process 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.

    2. BEA recommends that you use the maximum kernel setting for the max_thread_proc and maxusers parameters. Setting maxusers to a higher value increases other machine-wide limits, such as nkthread (the maximum number of kernel threads). The following table provides some examples.

    Parameter

    Old Value

    New Value

    Description

    max_thread_proc

    64

    Maximum threads per process

    maxfiles

    Soft file limit per process

    maxusers

    nkthread

    3635

    Total number of threads on the system

    nproc

    2068

    Maximum number of processes

    ncallout

    292

    2084

    Number of pending timeouts


     

    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: http://www.hp.com/products1/unix/java/java2/HPjconfig/index.html.

  2. The WebLogic Platform upgrade installer (pj_platform816_upgrade_generic.jar) throws an exception while upgrading

    3. If you try to perform one of these types of upgrade with the upgrade installer, a java.lang.OutOfMemory exception is thrown.

    You may need to increase the size of the thread stack with the -Xms and -Xmx options, as follows:

    java -Xms512m -Xmx512m -jar pj_platform816_upgrade_generic.jar

  3. If your application involves working with very large objects via RMI over IIOP, then it may encounter the following exception:

    4. java.rmi.MarshalException: ; nested exception is:

    org.omg.CORBA.MARSHAL: vmcid: 0x0 minor code: 0 completed:

    If you see this exception, you may need to increase the size of the thread stack with the -Xss option. The JVM default is 512 KB; the new value depends on the size of the object in question.

  4. The Smart Update tool cannot be used to upgrade your WebLogic Platform software from a previous 8.1 SP version to SP6 for the HP-UX 11i V2 on Itanium configuration. If you want to upgrade your existing WebLogic Platform 8.1 software to SP6, use the upgrade installer.
  5. While trying to load module mod_wl_20.so using Apache/2.0.55 HP-UX_Apache-based_Web_Server on HP-UX 11i V2 on Itanium, it may throw the following error:

    6. Unsatisfied code symbol '_Unwind_Resume' in load module

    To work around this problem:

    Add the following code

    LoadFile /usr/lib/hpux64/libunwind.so

    before the LoadModule code:

    LoadModule weblogic_module <Path for mod_wl_20.so>

    in $APACHE_HOME/conf/httpd.conf file.

  6. While trying to load module mod_wl128_20.so using Apache/2.0.55 HP-UX_Apache-based_Web_Server on HP-UX 11i V2 on Itanium, it may throw the following errors:

    7. Unsatisfied code symbol '__cxa_personality_routine' in load module.

    Unsatisfied data symbol '_ZTVN10__cxxabiv119__pointer_type_infoE' in load module

    Unsatisfied data symbol '_ZTVN10__cxxabiv117__class_type_infoE' in load module

    To work around this problem:

    Add the following two lines of code

    LoadFile /usr/lib/hpux64/libunwind.so

    LoadFile /usr/lib/hpux64/libCsup.so.1

    before the LoadModule code:

    LoadModule weblogic_module <Path for mod_wl128_20.so>

    in $APACHE_HOME/conf/httpd.conf file.

WebLogic Platform 8.1 SP6 Installation Instructions

To install WebLogic Platform 8.1 SP6 on HP 11i v2 on Itanium:

  1. Go to the BEA Downloads site (http://commerce.bea.com) and download the appropriate package installer:
  2. Install WebLogic Platform or WebLogic Server following the instructions provided for .jar installation files, as described in Installing WebLogic Platform.

    3. For example, if you are installing in console mode, enter the following at the command prompt:

    $ java -jar pj_platform816_generic.jar -mode=console

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

    http://download.oracle.com/docs/cd/E13196_01/platform/docs81/install/console.html#instcon003

    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_platform816_ja_generic.jar -mode=console

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