Known Issues

This section describes known issues that occur when WebLogic Server 9.0 is run on Red Hat Enterprise Linux 4.0 systems based on an Itanium, AMD64, or 64-Bit Xeon chip architecture. For descriptions of these issues and, when available, workarounds for them, see the appropriate section:

Serial Version UID Mismatch

A Serial Version UID Mismatch Issue may be encountered if you deploy an application on a latest JVM, but compiled with an earlier JDK release.

Workaround: To be compatible with the serialization of previously compiled applications, modify the <BEA_HOME>/Weblogic90/common/bin/commEnv.sh file to include the following command:

JAVA_OPTIONS="$JAVA_OPTIONS -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0"

Note: If you intend to deploy new applications with previously compiled applications, they must be recompiled as necessary to have the same Serial Version UID.

Issues with Configurations Based on Itanium, AMD64, or 64-Bit Xeon

When installing WebLogic Server on a system that includes NFS mounted file systems, you may see the following exception:

"Caused by:  java.lang.IllegalArgumentException: Can not list file system roots on this computer"

If you see this message, complete the following procedure:

  1. Make sure you have a minimum of 600 MB of disk space.
  2. Start the installation again, including the flag -Dspace.detection=false, as follows:
    3. java -Dspace.detection=false -jar server900_generic.jar -mode=console

Download and Installation Instructions

This section provides procedures for downloading and installing the software required to run WebLogic Server 9.0 on a configuration based on Red Hat Enterprise Linux 4.0 on either (a) Itanium, or (b) AMD64 or 64-Bit Xeon. See the instructions appropriate for your configuration:

Instructions for Red Hat Enterprise Linux 4.0 on Itanium

To install WebLogic Server 9.0 on a configuration comprising Red Hat Enterprise Linux 4.0-2 on Itanium, you must have JRockit 5.0 and the installer for WebLogic Server 9.0. This section provides instructions for:

Downloading and Installing JRockit 5.0

  1. Download and install the 64-bit JRockitTM 5.0 R26 JDK (R26.0.0-188) for Itanium-based machines hosting Linux systems.

    2. Note: For information on how to download BEA products refer to My Oracle Support Note 762254.1 and My Oracle Support Note 763603.1.

    The BEA Download Center (i.e. http://commerce.bea.com) will be decommissioned on February 2, 2009. After this time, customers will be able to download the BEA software from Oracle's E-delivery portal (http://edelivery.oracle.com) or Oracle Technology Network (http://otn.oracle.com).

  2. Update the JAVA_HOME environment variable to reflect the JDK installation directory. For example:
    3. export JAVA_HOME=<JRockit_installation_directory>
  3. Add your Java executables to the PATH environment variable: 
    4. export PATH=$JAVA_HOME/bin:$PATH

Downloading and Installing WebLogic Server 9.0

  4. Set the BEA_HOME variable to point to the directory in which WebLogic Server is installed and export BEA_HOME. For example: 
    5. export BEA_HOME=<your_WebLogic_Server_installation_directory>
  5. In a text editor, open the script that is used to set up your WebLogic Server environment: $BEA_HOME/weblogic90/common/bin/commEnv.sh.
