Appendix C Configuration File Parameters for ContinentalClusters

This is a time interval, in minutes and/or seconds, after which the notifications defined in the associated NOTIFICATION parameters are sent and failover to the Recovery Cluster using the cmrecovercl command is enabled. This number must be a positive integer. Minimum is 30 seconds, maximum is 3600 seconds or 60 minutes (one hour)

This is a time interval, in minutes and/or seconds, after which the notifications defined in the associated NOTIFICATION parameters are sent. Failover to the Recovery Cluster using the cmrecovercl command is not enabled at this time. This number must be a positive integer. Minimum is 30 seconds, maximum is 3600 seconds or 60 minutes (one hour)

This is the domain of the nodes in the previously specified cluster. This domain is appended to the NODE_NAME to provide a full system address across the WAN.

Clustername/Status

This is a cluster name associated with one of the following changes of status:

The maximum length is 47 characters.

When the MONITORING_CLUSTER detects a change in status, one or more notifications are sent, as defined by the NOTIFICATION parameter, at time intervals defined by the CLUSTER_ALERT and CLUSTER_ALARM parameters.

The name of a member cluster within the continental cluster. It should be the same name that is defined in the MC/ServiceGuard cluster configuration ASCII file. Maximum size is 40 characters.

All nodes in the cluster should be listed after this variable using the NODE_NAME variable. A MONITOR_PACKAGE_NAME and MONITOR_INTERVAL should also be associated with each CLUSTER_NAME.

name

The name of a continental cluster managed by the ContinentalClusters product. Maximum size is 40 characters. This name cannot be changed after the configuration is applied. You must first delete the existing configuration if you want to choose a different name.

clustername/packagename

This variable is only used if the data replication is carried out by a separate software application that must be kept highly available. If the replication software uses a receiver process, you include this variable in the configuration file. Maximum size is 81 characters.

The parameter consists of a pair of names: the name of the cluster that receives the data to be replicated (usually the Recovery Cluster) as defined in the MC/ServiceGuard cluster configuration ASCII file, followed by a slash ("/"), followed by the name of the data replication receiver package as defined in the MC/ServiceGuard package configuration ASCII file. Some replication software may only have a receiver package as separate package because the sender package is built into the application.

clustername/packagename

This variable is only used if the data replication is carried out by a separate software application that must be kept highly available. If the replication software uses a sender process, you include this variable in the configuration file. Maximum size is 81 characters.

The parameter consists of a pair of names: the name of the cluster that sends the data to be replicated (usually the Primary Cluster) as defined in the MC/ServiceGuard cluster configuration ASCII file, followed by a slash ("/"), followed by the name of the data replication sender package as defined in the MC/ServiceGuard package configuration ASCII file. Some replication software may only have a receiver package as separate package because the sender package is built into the application.

n

The interval, in seconds, that the ContinentalClusters monitor polls the cluster, nodes, and packages to see if the status has changed. This number must be an integer. The minimum value is 30 seconds, the default is 60 seconds, and the maximum is 300 seconds (5 minutes).

This is the name of the MC/ServiceGuard package containing the ContinentalClusters monitor. Maximum size is 40 characters.

Name

This is name of the cluster that polls the cluster named in the CLUSTER_EVENT and sends notification. Maximum length is 40 characters.

This is the unqualified node name as defined in the DNS name server configuration. Maximum size is 40 characters.

This is a destination and message associated with a specific CLUSTER_ALERT or CLUSTER_ALARM. The maximum size of the message string is 170 characters including the quotation marks. The message string must be entered on a separate single line in the configuration file.

The following destinations are acceptable:

Any number of notifications may be associated with a given alert or alarm.

Clustername/Packagename

This is a pair of names: the name of a cluster as defined in the MC/ServiceGuard cluster configuration ASCII file, followed by a slash ("/"), followed by the name of the primary package as defined in the MC/ServiceGuard package configuration ASCII file. Maximum size is 81 characters.

name

This is a name for the set of related primary packages on one cluster and the recovery packages on another cluster that protect the primary packages. The maximum size is 40 characters.

You create a recovery group for each package that should be started on the recovery cluster in case of a failure on the primary cluster. A PRIMARY_PACKAGE and RECOVERY_PACKAGE should be associated with each RECOVERY_GROUP_NAME.

Clustername/Packagename

This is a pair of names: the name of the recovery cluster as defined in the MC/ServiceGuard cluster configuration ASCII file, followed by a slash ("/"), followed by the name of the recovery package as defined in the MC/ServiceGuard package configuration ASCII file. Maximum size is 81 characters.
