Class PropertyConfigurator

  org.logicalcobwebs.proxool.configuration.PropertyConfigurator

public class PropertyConfigurator
extends java.lang.Object

Uses a standard Java properties file to configure Proxool. For example:

 jdbc-0.proxool.alias=property-test
 jdbc-0.proxool.driver-url=jdbc:hsqldb:.
 jdbc-0.proxool.driver-class=org.hsqldb.jdbcDriver
 jdbc-0.user=foo
 jdbc-0.password=bar
 jdbc-0.proxool.house-keeping-sleep-time=40000
 jdbc-0.proxool.house-keeping-test-sql=select CURRENT_DATE
 jdbc-0.proxool.maximum-connection-count=10
 jdbc-0.proxool.minimum-connection-count=3
 jdbc-0.proxool.maximum-connection-lifetime=18000000
 jdbc-0.proxool.simultaneous-build-throttle=5
 jdbc-0.proxool.recently-started-threshold=40000
 jdbc-0.proxool.overload-without-refusal-lifetime=50000
 jdbc-0.proxool.maximum-active-time=60000
 jdbc-0.proxool.verbose=true
 jdbc-0.proxool.trace=true
 jdbc-0.proxool.fatal-sql-exception=Fatal error
 jdbc-0.proxool.prototype-count=2

 jdbc-1.proxool.alias=property-test-2
 jdbc-1.proxool.driver-url=jdbc:hsqldb:.
 jdbc-1.proxool.driver-class=org.hsqldb.jdbcDriver
 jdbc-1.user=scott
 jdbc-1.password=tiger
 jdbc-1.proxool.house-keeping-sleep-time=40000
 jdbc-1.proxool.house-keeping-test-sql=select CURRENT_DATE
 jdbc-1.proxool.maximum-connection-count=10
 jdbc-1.proxool.minimum-connection-count=3
 jdbc-1.proxool.maximum-connection-lifetime=18000000
 jdbc-1.proxool.simultaneous-build-throttle=5
 jdbc-1.proxool.recently-started-threshold=40000
 jdbc-1.proxool.overload-without-refusal-lifetime=50000
 jdbc-1.proxool.maximum-active-time=60000
 jdbc-1.proxool.verbose=true
 jdbc-1.proxool.trace=true
 jdbc-1.proxool.fatal-sql-exception=Fatal error
 jdbc-1.proxool.prototype-count=2
 

The first word (up to the first dot) must start with "jdbc", but it can be anything you like. Use unique names to identify each pool. Any property not starting with "jdbc" will be ignored.

The properties prefixed with "proxool." will be used by Proxool while the properties that are not prefixed will be passed on to the delegate JDBC driver.
