Agents Pending Token alarm

The Agents Pending Token alarm becomes active when the number of agents waiting for a token (a permission to run) in comparison to the total number of registered agents for the DB2 instance reaches a threshold percentage.

This alarm has been predefined with a Low severity level. The underlying metric for this alarm can be adjusted to suit your environment by using the Metric Editor.

What you can do

Determine whether the current value for the MAXAGENTS database configuration parameter is appropriate for your system. Some environments might use the MAXAGENTS parameter value to limit the number of processing tokens, thereby limiting the amount of execution concurrency in the database manager. Although this strategy might be beneficial to the system as a whole, it can impact applications, causing problems such a high percentage of agents awaiting tokens.

Configuration parameter edits

If your are running Quest Central for DB2, you can easily obtain information about and edit the DB2 database configuration parameters defined for a specific database. In the object tree in the left pane of the Quest Central for DB2 database explorer, right-click the database name. Select Configure to display an alphabetized list of the configuration parameters and their values defined for the database. Select a parameter to display a brief description of the parameter and to edit its value.
