An Agent is showing inactive in the Workload Automation DE Desktop Client Topology.
The problem was caused by name resolution. WA Agent was not able to resolve WADE Manager host name. The following errors were recorded in the WA Agent transmitter.log file:
03/20/2017 14:16:28.020 UTC+0000 1 TCP/IP Controller Plugin.Transmitter pool thread <Slow:1>.CybTargetHandlerChannel.constructConversation[:1139] - Error connecting to DS_<manager_name>
cybermation.library.communications.CybConversationConnectException: Unknown host: manager_name
WADE Agent 11.3.x, Windows/UNIX/Linux
To ensure that WA Agent can successfully resolve WADE Manager's host name (either short name or fully qualified name, depending on how it has been defined in the agentparm.txt file), either add the WADE Manager hostname to the hosts file on the WA Agent machine or update DNS so that the WADE Manager name can be resolved successfully.
