Web Accelerator 4500 Platform
This WebAccelerator system release includes support for the 4500 platform. This platform includes two 139GB RAID hard drives and redundant power supplies to ensure continuous operation in the event of power supply failure. Additionally, this platform is compliant with the Restriction of Hazardous Substances (RoHS) regulations and meets RoHS guidelines regarding lead-free electronic equipment.
PDF version 1.4 documents (CR65046)
The WebAccelerator system now properly handles PDF version 1.4 documents.
X-PvInfo response header value (CR65047)
The value for the X-PvInfo response header's S code, which under certain conditions was incorrectly displaying a value of 0, now displays the proper value.
Changes in US and Canada Daylight Saving Time (CR73948)
The Energy Policy Act of 2005, which was passed by the US Congress in August 2005, changed both the start and end dates for Daylight Saving Time in the United States, effective March 2007. Canada is also adopting this change. The resulting changes have been addressed in this version of the product software. To find out more about this issue, refer to SOL6551: F5 Networks software compliance with the Energy Policy Act of 2005.
After you install the WebAccelerator software, or any time you modify the pvsystem.conf file, you must stop and restart the WebAccelerator system, by typing the following commands:
service pivia stop
service pivia start
The following items are known issues in the current release.
Loading policies during initial WebAccelerator software installation (CR68441)
When performing the initial installation of the WebAccelerator software, a policy may fail to load. If this occurs, the WebAccelerator system reports the failure in the installation log, and the policy does not display in the pre-defined policy list. To view the installation log, type the /tmp/pvinstall.log command. If the installation log reports missing policies, see Installing policies manually in the Workaround for known issue section.
pvac stack trace reports error (CR68783)
When the pvac process shuts down for any reason (for instance, if you use the /etc/init.d/pivia stop and /etc/init.d/pivia stop restart commands to shut it down manually, or if you reboot the WebAccelerator system), or when you view the version information using the /etc/init.d/pivia versionx, the pvac stack trace reports the following error message: Caught terminating signal, probably due to invalid application state. This error is benign.
Network configuration script (CR68985)
The network configuration script does not validate network configuration settings, and the Management Console does not report any existing network misconfigurations. To avoid issues, verify your network configuration settings carefully before rebooting the WebAccelerator system. If you discover an error in your network configuration, rerun the network configuration script and correct the issue before rebooting.
Licensing the WebAccelerator system from the Management Console (CR72027)
If you attempt to license, from the Management Console, a WebAccelerator system that does not have a route to the F5 license server, the licensing process fails and you receive a Network unreachable error. To work around this issue, license the WebAccelerator system using the procedure described in SOL6697: Installing a license from the command line.
Providing the dossier for licensing (CR70231)
When you are using the Management Console to manually license the WebAccelerator system, the dossier does not display properly. To work around this issue, license the WebAccelerator system using the procedure described in SOL6697: Installing a license from the command line.
The following section describes the workaround for the corresponding known issue listed in the previous section.
If the installation log reports missing policies after you perform the initial installation of the WebAccelerator software, perform the following steps to install the missing policies manually.
To manually install missing policies
/etc/init.d/pivia import_config -f /opt/pivia/dac/policies/predefined/FAILED_POLICY.xml -c /opt/pivia/dac/conf/pvsystem.conf -a administrator -p PASSWORD -r -u -y
PASSWORD is the administrator password you assigned when you installed the WebAccelerator software.
FAILED_POLICY.xml is the name of the missing policy, as reported in the installation log.
