Issue/Introduction

After agent IP address change, the Workload Automation DE Server could not communicate with Agent and jobs status reported AGENTDOWN

 

Environment

Component: ESP Workload Automation DE (dSries)

Resolution

Generally, job in AGENTDOWN status indicates that the CA Workload Automation (CAWA) Server and Agent could not communicate with each other and therefore, job cannot be submitted to the Agent.

There could be several reasons why the WA DE Server and Agent cannot communicate among others;

• CAWA Server cannot establish connection to the Agent due to firewall or DNS name resolution problem.
  
  
• Agent is not running.
  
  
• Mismatch in Agent definition in WA DE Server topology and Agent parameter configuration in agentparm.txt file like agent address, port, and encryption key/cipher.

If agent IP address changed, then WA DE Server won't be able to communicate with agent and. Exception like below is logged in server tracelog;

Exception caught sending to agent: The conversation is unable to connect to partner <AGENT NAME>:<AGENT PORT>.
The exception is Connection timed out: could be due to invalid address.

If agent IP address cache on the WA  DE Server java side, restart WA de Server to remove the cache that holds the old IP address.
