First, launch Windows Task Manager to see if the system has run out of memory. When Available

Physical Memory displays zero, the host is RAM paging. If this is encountered, and the host does not

have at least 3 GB of RAM, consider the appropriate actions:

 Add more RAM.

 Be sure you are using a separate host to run the client.

NOTE The client also requires a full 1 GB of RAM. Client and server applications running on the

same host tend to use lots of RAM.

 Scale back the amount of memory being used by the SQL instance (Tools, Options, Shared,

General settings). While this sounds like it will impede performance, it may actually free up some

memory to be used by the HP Web Jetadmin service.

 Evaluate your HP Web Jetadmin host and usage:

 Are too many users adding tasks like Discovery, Exporting, and Reporting to the system?

 Is it severely underpowered for the way in which it is being used?

 Is it being shared for other high-overhead applications?

 Is it being run on a virtualized operating system (OS) that is not set up with proper resources

or is it on a system that is itself underpowered?

Other resources for planning and implementation

A number of documents and online help can be used for planning and implementation of HP Web

Jetadmin. The materials are available by going to www.hp.com/go/wja and clicking Self Help and

Documentation, or from within the application itself, as stated below:

 “Web Jetadmin User Guide” (available via the software’s online help)

 “Web Jetadmin Installation and Setup Guide” (available via the software’s online help)

 “HP Web Jetadmin Migration Too” (available via the software’s online help)

 “HP Web Jetadmin Security”

 “Discovering Devices in HP Web Jetadmin”

 “HP Web Jetadmin Late Breaking News”

Enterprise systems management integration

HP Web Jetadmin provides a bridge link for enterprise systems management applications such as

HP OpenView or IBM Tivoli. These applications and others can be configured to launch HP Web

Jetadmin software for specific printers and other imaging devices found within the enterprise

application. Here is how an administrator might use this functionality when managing devices within

an application such as HP OpenView.

IT administrators can use HP OpenView, Network Node Manager to monitor the status of network

hosts such as routers, switches, servers, and devices. This is done within a Network Node Manager

displayed map of the network or network segment. However, to arrive at appropriate and specific

printing or digital imaging detail, the administrator requires the help of a tool that is focused on the

wide variety of features needed to manage these devices. HP Web Jetadmin is that tool.

Once the HP Web Jetadmin linkage, or “bridge,” has been created within HP OpenView, the

administrator simply configures any printing or imaging device to launch an HP Web Jetadmin device

view when they are selected. HP Web Jetadmin activates this device view launch with this simple URL

format: http://WJAServer:8000/device/xxx.xxx.xxx.xxx, where xxx.xxx.xxx.xxx is the IP address of

the device (you can also use the device hostname). When HP Web Jetadmin is launched in this way,

the application loads with the device pre-selected in the All Devices list within HP Web Jetadmin.

Again, the linkage used to support the HP OpenView bridge is generic enough to be used in any

enterprise systems management application that can be configured, or “bridged,” into an application
