Distributed Index Handler 25.4
Distributed Index Handler Help

# Polling

Set this parameter to `false` to prevent the Distributed Index Handler from periodically polling each job in the index queue for this child server to determine the jobs that are complete.

If `Polling` is to set `false`, DIH reports a job finished after the action has been sent.

You can also set the Polling parameter in the `[Server]` section to configure the value for all child servers.

NOTE: If you turn off Polling in the `[Server]` section, DIH does not create polling threads for its child servers, and you cannot turn `Polling` on for individual child servers.

If Polling is set to `true` in the `[Server]` section, you can turn it off for individual child servers.

You can use only a single value for `Polling`, even if you create a server group by specifying a comma-separated list of host names in the Host parameter.

Type: | Boolean
Default: | True
Required: | No
Configuration Section: | IDOLServer `N` or DIHEngine `N`
Example: | `Polling=true`
See Also: | PollInterval Polling (`[Server]` section)
