HP Web Jetadmin - Performance and Threadpools in HP Web Jetadmin

the firmware file to the device and reports success after the file is delivered in its entirety. This can

eliminate potentially 90% of the transaction time per device, meaning many more devices are

completed in a fraction of the previous time when status checking was being employed.

Perform the following steps:

1. Using a text editor, edit the existing file on the HP Web Jetadmin host system in one of the

following location:

 Windows 2003 Server / XP:

DRIVE:\Documents and Settings\NetworkService\Local Settings\Application Data\Hewlett-

Packard\HPWebJetadmin\WjaService\config\FirmwareUpgrade.config.xml

 Windows 7 / 2008 / Vista:

DRIVE:\Windows\ServiceProfiles\NetworkService\AppData\Local\Hewlett-

Packard\HPWebJetadmin\WjaService\config\ FirmwareUpgrade.config.xml

2. Change the values for IsJetdirectMonitorRequired and IsPrinterMonitorRequired from True to False:

<type>HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString</type>

</property

<type>HP.Imaging.Wjp.Sdk.Core.Framework.ConfigurationItemString</type>

</property>

3. Change the values to False to bypass status checking for HP Jetdirect and/or printer firmware and

significantly speed up batch upgrades.

4. Save the file and restart the HP Web Jetadmin service (HPWJA Service). Notify all users logged

into the system about the service restart and ensure that active HP Web Jetadmin tasks are

stopped or rescheduled to avoid problems with the restart.

NOTE Use standard XML format when creating this file. Use a simple text editor such as Microsoft®

Notepad. Line breaks should occur only after the appropriate tag at the end of a statement.

Documentation viewers might add what appear to be line breaks in the XML content shown

above.

Since HP Web Jetadmin now reports success only after the file deliveries are complete, to check

completion status on the devices, check the Device Firmware Version and Device Firmware Date

columns to determine if successful.

SUMMARY

Sizing an HP Web Jetadmin installation and optimizing it for performance can be challenging. The

hardware where HP Web Jetadmin is installed, enabled features, and number of devices directly

influences the performance of an HP Web Jetadmin installation. This document discussed techniques

for how to potentially improve the performance of many tasks in HP Web Jetadmin by manipulating

the number of threads to be used for each task. Configuring the Windows Paging File Size to provide

reliable support for very large servers is also crucial to improving performance and eliminating

memory out conditions (crashes).
