Test connection takes several minutes before returning failure

You select an engine connection and click Test Connection to check that the communication is working. The test takes several minutes to complete and then returns a failure.

Cause and solution:

When the Test Connection is run, the result is returned only after the timeout expires. The timeout for running the Test Connection operation cannot be customized. The connection failed because of one of the following reasons:

The system where the IBM Workload Scheduler engine is installed is not active.
The IP address or the hostname of the system where the IBM Workload Scheduler engine is installed was not correctly specified (in other words, the host name specified by the showHostProperties command must be capable of being contacted by the Dynamic Workload Console and vice versa)
A network firewall prevents the system where the Dynamic Workload Console is installed and the system where the IBM Workload Scheduler engine is installed from communicating.

Check which of these reasons causes the communication failure, fix the problem, and then retry.
