You can use system settings to control how often the system queries
a server for its manifest properties.
By default, the system checks Built-in and Set Value properties
more frequently than Run Command properties. It uses several system settings
to determine when to perform updates:
- The settings Active server refresh interval and Inactive
server refresh interval set the number of seconds between updates
of Built-in and Set Value properties. The settings discriminate between active
(currently running a project) and inactive (not currently running a project)
servers, so that you can have properties refresh more frequently on servers
when they are being used.
- The setting Default _AGE sets the number of seconds
between updates of Run Command properties. These properties, which require
that the system run a command on the server to get updated data, create more
network traffic during their updates. The default value for this setting is
86400, which provides for updates once per day. IBM does not recommend setting
a value lower than this setting unless the values you retrieve through Run
Command properties change frequently.
You can use a collector to set a value for _AGE that applies
only to the servers that use that collector. When you use the special name
_AGE for a variable, the system interprets its value as the desired number
of seconds between updates. To set this up:
