Monitoring the settings

The number of allocates rejected by the queue control mechanism should be monitored. If there are too many, it may indicate a lack of resources to satisfy the demands on the system—or poor tuning.

The number of times the queue is purged should indicate the number of times a serious problem occurred on the remote system. If the purges do not happen when the remote system fails to respond, examine the setting of the MAXQTIME parameter—it may be too high, and insensitive. If the indication of a problem is too frequent and causes false alarms due to variations in response time of the remote system, the parameter may be too low, or the QUEUELIMIT value too low.
