NAME
SUNW.derby, derby - resource type implementation of the Java DB database
DESCRIPTION
SUNW.derby is the failover resource type that enables you to use the Java DB database with Sun Cluster. The Java DB database is based on
the Derby database. For information about the database, see http://db.apache.org/derby/.
The extension properties associated with the SUNW.derby 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 omit-
ting the -C option for pmfadm(1M) (all children and their descendents are monitored).
Category Optional
Default -1
Tunable At creation
DB_path(string)
Specifies the location of the data file for the Java DB database.
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.
Category Mandatory
Default -1
Tunable At creation
DB_port(integer)
Specifies the port for the Java DB database.
Category Mandatory
Default 1527
Tunable At creation
DB_probe_port(integer)
Specifies the port that Sun Cluster uses to test the health of the server for the Java DB database.
Category Mandatory
Default 1528
Tunable At creation
Monitor_retry_count(integer)
Controls fault-monitor restarts. The property indicates the number of times that the process monitor facility restarts the fault moni-
tor. 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.derby resource.
Category Optional
Default 2
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 Mon-
itor_retry_count, the process monitor facility does not restart the fault monitor.
Category Optional
Default 2 minutes
Tunable Anytime
Probe_timeout(integer)
Specifies the timeout value, in seconds, for the probe command.
Category Optional
Default 30 seconds
Tunable Anytime
