15.3.8 Setting the agent host name resolution option
Resolution of agent host names might fail on the manager host if, for example, the host names are not correctly set in the hosts file or DNS. If an attempt is made to start or stop the JP1/AJS3 service on the manager host or an agent host when agent host names cannot be resolved, the following problems could occur:
-
The status of an event job registered for execution takes a long time to change to Now running.
-
Detection of an event monitored by an event job or start conditions is delayed.
-
The status of an event job or a jobnet with start conditions takes a long time to change when, for example, the job or jobnet is forcibly terminated.
-
The JP1/AJS3 service on the manager takes a long time to stop.
-
The JP1/AJS3 service on the manager takes a long time to start.
You can prevent these problems from occurring by setting the agent host name resolution option.
Note that you do not need to enable this option in an environment in which all agent host names can be resolved.
This option is effective only for a compatible ISAM configuration.
The following describes how to enable the option.
