CL Command Reference - CHGCLUCFG
CL Command List > CHGCLUCFG Reference
Description:
The Change Cluster Configuration (CHGCLUCFG) command is used to tune cluster performance and configuration parameters. The command provides a base level of tuning support where the cluster will adjust to a predefined set of values identified for maximum, minimum, and normal timeout and messaging interval values. If an advanced level of tuning is desired, usually anticipated with the help of IBM support personnel, then individual parameters may be tuned over a predefined range of values using the Change Cluster Resource Services (QcstChgClusterResourceServices) API.
Values for current settings may be retrieved using the Display Cluster Information (DSPCLUINF) command.
Restrictions:
1. You must have input/output system configuration (*IOSYSCFG) special authority to run this command.
2. This command cannot be called from a cluster resource group exit program.
3. This command must be called on a cluster node with a status of Active.
4. The tuning parameters defined under the Change Cluster Resource Services (QcstChgClusterResourceServices) API must match exactly in both partitions for a merge to be allowed.
Examples:
CHGCLUCFG CLUSTER(MYCLUSTER) LEVEL(*MIN)
This command changes the configuration and tuning level of the cluster MYCLUSTER. The tuning level is set to the minimum sensitivity level.
