Issue/Introduction

I have three WCC instances. Schedulers/Operators can use the Enterprise Command Line on only two of the three instances. On the third instance, the ECL hangs with the following error when executing a command:

WCLI8000 - The command request timed out. 

Environment

CA Workload Control Center r11.4 SP3

Resolution

Restart the iGateway service of the Autosys instance you are trying to run your ECL command(s) against.
