NAME

SUNW.HADerby, HADerby – resource type implementation of the Derby database

Description

SUNW.HADerby is the failover resource type that enables you to use the Derby data base with Sun Cluster. For information about the Derby database, see http://db.apache.org/derby/.

The extension properties associated with the SUNW.HADerby resource type are as follows:

Child_mon_level(integer)

Provides control over the processes that are monitored through the process monitor facility. This property denotes the level to which the forked children processes are monitored. Omitting this property or setting this property to the default value is the same as omitting the -C option for pmfadm(1M) (all children and their descendents are monitored).

The value for DB_path is a string specifying PATH. The specified path should be a path controlled by your chosen storage, for example HAStoragePlus.

Monitor_retry_count(integer)

Controls fault-monitor restarts. The property indicates the number of times that the process monitor facility restarts the fault monitor. The property corresponds to the -n option passed to the pmfadm(1M) command. The Resource Group Manager (RGM) counts the number of restarts in a specified time window (see Monitor_retry_interval). Note that Monitor_retry_count refers to the restarts of the fault monitor itself, not of the SUNW.HADerby resource.

Tunable

Anytime

Monitor_retry_interval(integer)

Indicates the time window in minutes during which the RGM counts fault-monitor failures. The property corresponds to the -t option passed to the pmfadm(1M) command. If the number of times that the fault monitor fails exceeds the value of the extension property Monitor_retry_count, the process monitor facility does not restart the fault monitor.
