MQSeries_ChInst_per_Client_High  
Situation Description
Suggested Actions
Situation Description

The % Max Instances per Client value in the Channel Summary workspace is greater than 80%. The % Max Instances per Client attribute reflects the highest number of the channel instances that are grouped by clients as percentage of the maximum number of instances that can be started for a channel from a single client.

 

Suggested Actions

Navigate to the Channel Summary workspace for the server-connection channel that triggers this situation, check the values of the Highest Instances per Client and Maximum Instances per Client attributes, evaluate if the value of the channel parameter, MAXINSTC (the maximum number of simultaneous instances of a server-connection channel that can be started from a single client), is large enough, and determine if a larger value is required by the potential for a large number of the server-connection channel instances from a single client. If the MAXINSTC value is fairly large, consider balancing MQI applications among all the clients or offloading part of the MQI applications to other server-connection channels or to other queue managers. For details of all the channel instances, check the Channel Performance and Channel Status workspaces.
