Introduction:
When trying to connect to the SCM Harvest broker you will sometimes get a “-306” or “-307” communication error. Understanding these error codes will help to more quickly resolve the problem.
Question:
What do the “-306” and “-307” comm error codes mean and how can these errors be resolved?
Environment:
CA Harvest SCM all versions, all platforms
Answer:
The “-306” comm error generally means the Harvest SCM client component (Workbench, Administrator Tool, Command Line utility, plugin or Harweb) cannot find the broker (or agent) machine and/or connect to the port - either the client machine is not connected to the network, broker (or agent) host name does not resolve to the correct IP address, the client cannot connect across the network to the broker (or agent) machine (unreachable), or a firewall is blocking the port.
Things to check:
The “-307” comm error generally means the Harvest SCM client component (Workbench, Administrator Tool, Command Line utility, plugin or Harweb) can find the broker machine and the port is open, but the broker is down or is known by a different name.
Things to check:
Additional Information:
More information on configuring communications between the Harvest SCM Broker and Clients can be found in the Implementation Guide.
If issue is seen in new Harvest Broker server, check system resources and see if they are sufficient.
