IBM 5.5 manual Configuring remote load balancing, Dependencies

For example, to allow on-demand connectivity for all Cisco 15454 (NEType name= “ONS15454”) devices, add the following lines to the precisiontn.xml file:

<properties name="NEPollingExtension ">

<property name="ne.polling.association.AssocControlledNETypes" value="{ONS15454}" />

</properties>

Dependencies

The simple configuration extension must be loaded before the on-demand connectivity feature. Check that the lfserver_ext_assembly.xml file has the lf-svc-scheduler.jarfile entry listed after the lf-cfgpol-simple.jarentry.

Configuring remote load balancing

Netcool/Precision TN can perform remote load balancing by controlling the amount of traffic sent to a remote target, whether it is a single device, gateway, or an EMS.

In order to support fragile or specific network limitations and requirements, Netcool/Precision TN allows you to specify the number of threads to use for polling on a per NEType basis.

This setting will prevent some agents (whether a single device or EMS) being overloaded, or crash, due to excessive management traffic.

Packaging and configuration

This feature is delivered as part of the scheduler extension in the lf-svc-scheduler.jarfile. It must be added in the lfserver_ext_assembly.xml configuration file, to be loaded with any other extensions.

A set of NETypes can be associated with a given queue, with a number of threads to process it. The NEPollingExtension parameter defines the ne.polling.thread.PrivateThreadQueue property whose syntax is a set of pairs composed by a named value (Names=Value) set of NEType names and the number of threads separated by commas.

For example, to instruct Netcool/Precision TN to poll Cisco 15454 and Cisco 15327 NEs one at a time, add the following lines to the precisiontn.xml file:

<properties name="NEPollingExtension ">

<property name="ne.polling.thread.PrivateThreadQueue " value="{{ONS15454,ONS15327}=1}" />

</properties>
