JDBC Detector

The JDBCDetector connects to a JDBC-enabled database and tries to fetch its catalog. If the fetch is successful, it returns the detected value. If it is not successful, it returns the not detected value.

Configuration and use

The JDBCDetector uses the common configuration parameters.

Table 1. Parameters for the JDBCDetector
Parameter	Description	Default value
Required
dbDriver	Database driver class name.	org.postgresql.Driver
password	JDBC password.	Empty String object.
url	JDBC URL to query. Note: this URL can differ based on JDBC drivers, databases, and so on.	`jdbc:postgresql://localhost/opennms`
user	JDBC username.	postgres
Optional
port	Port to query.	3306

Database driver

The JDBCDetector requires a JDBC driver to communicate with any database. Meridian uses a PostgreSQL database, so the PostgreSQL JDBC driver is included out of the box. For all other database systems, you must provide a compatible JDBC driver as a .jar file. To provide a JDBC driver, place the driver-jar in your ${OPENNMS_HOME}/lib folder.

Examples

<detector name="MySQL-JDBC" class="org.opennms.netmgt.provision.detector.jdbc.JdbcDetector">
    <parameter key="password" value="borkborkbork"/>
    <parameter key="user" value="opennms"/>
    <parameter key="dbDriver" value="com.mysql.jdbc.Driver"/>
    <parameter key="url" value="jdbc:mysql://OPENNMS_JDBC_HOSTNAME:3306/test"/>
    <parameter key="timeout" value="5000"/>
</detector>

This example assumes you have loaded the MySQL driver file (see Install JDBC Driver).
