Configuring dynamic agent communications through a gateway
In some complex network topologies, the master domain manager or
the dynamic domain manager are
prevented from directly communicating with the dynamic agent.
Before you begin
In a simple configuration, dynamic agents connect directly to
the master domain manager or to the dynamic domain manager. However, in more complex network
topologies, if the network configuration prevents the master domain manager or the dynamic domain manager from directly communicating with the
dynamic agent, for example, if the agents
are behind a firewall and need to communicate through the internet, or if they need to communicate
with a Network Address Translation (NAT) process, then you can configure your dynamic agents to use
a local or remote gateway.
About this task
You can set up your dynamic agents to use a gateway for communication
with the master domain manager or
to the dynamic domain manager when
you install a dynamic agent, or you can configure a gateway subsequent
to the installation.
To
configure an existing HCL Workload Automation version
9.2 or later dynamic agent to
communicate to its master domain manager or dynamic domain manager through
a local gateway, perform the following configuration steps:
Procedure
Edit the JobManager.ini file on the dynamic agent workstation
that you want to configure to communicate through a gateway. Edit
the [ResourceAdvisorAgent] section so that the value of the ResourceAdvisorURL parameter
is https://$(tdwb_server):$(tdwb_port)/ita/JobManagerGW/JobManagerRESTWeb/JobScheduler/resource ,
where, $(tdwb_server) and $(tdwb_port) correspond to
the host name and port of the gateway that you want to use for communication
with the master domain manager or
the dynamic domain manager.
Stop and start the dynamic agent to
implement the changes.
Results
The master domain manager or dynamic domain manager can now communicate with the
dynamic agent workstation
through the gateway.
Note:
If you have more than 100 dynamic agents that communicate
through one single gateway to the master domain manager or dynamic domain manager, in the
JobManagerGW.ini file on the dynamic agent workstation where the
gateway resides, set the ActionPollers parameter as described in Configuring general properties [ITA].
Only for version 9.5 Fix Pack 4, if you
install your agents so that they communicate with the master through a remote gateway, ensure
that they can reach the master directly at installation time. For more information, see Dynamic agent gateway installation examples
Example
The following diagram depicts a network topology where
the master domain manager communicates to the dynamic agents, located
behind a firewall, through a gateway configured on one of the dynamic
agents.
The following are the configuration settings used in
the network topology depicted in the figure:
