### 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 Oracle Solaris 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:

`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`.

`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.derby` resource.

`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.
