Take Action commands show return code 0, but might be unsuccesful
Take Action commands are a standard feature of the Tivoli® Enterprise Portal in IBM® Tivoli Monitoring and are described in the user's guide. In general, Take Action commands display a zero (0) return code in the Tivoli Enterprise Portal (which is always located on a distributed system). This code indicates successful submission of the command. The portal does not display the actual result of the command being executed. For information on the result of command execution refer to the command output in the z/OS® SYSLOG for the specific system that is the target of the Take Action command.
