Disabling Tarari XML Acceleration Services and Removing the Accompanying Drivers

Issue/Introduction

The Tarari XML Accelerator is a hardware-based XML processing acceleration solution. It is an application-specific hardware solution to provide more throughput and bandwidth to XML-related message processing. It allows an application to perform XML-related operations (such as XPath, XSLT, and digital signatures) much faster than traditional hardware.

As time and technology moved forward, the capabilities of the hardware were overpowered by faster CPUs. The performance benefit of XML acceleration with a PCI expansion card against additional central processing power was decreased. As a result, Layer 7 Support has begun recommending that customers disable the Tarari implementation if their hardware appliance is not currently using it. Additionally, we recommend that customers using virtual appliances completely remove support for Tarari XML acceleration software. To completely decommission the Tarari acceleration you must disable the Tarari service and remove the Tarari drivers.

Environment

Release:
Component: APIGTW

Cause

Tarari XML Acceleration is deprecated as of 8.0 and is not recommended for use in any version of the Layer 7 Gateway virtual appliance. 

Resolution

Disabling the Tarari services

Log into the Gateway appliance as the ssgconfig user.
Select Option #3: Use a privileged shell (root).
Stop the Gateway service: service ssg stop

Stop the Tarari service: service tarari stop
Disable the Tarari service: chkconfig tarari off

Removing the Tarari services

Remain logged into the Gateway appliance as the root user.

Relocate the drivers to a new location:
