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
