Bonecp는 dbcp, c3p0 를 대체하는 고성능의 Java database connection pool 구현물.

사용조건

JDK 1.5 이상
Google Guava library 필요
SLF4J logging library 필요

설정 값 및 성능 자료

설정값

partitionCount : Pool 에서 connection 을 가져올때 lock 경쟁을 최소화하기 위해 pool 을 여러 개 파티션으로 나눌수 있음. 기본값은 1이며 높은 성능이 필요할 때 3~4 정도 추천
maxConnectionsPerPartition: 파티션별 Connection 수. 전체 Connection 은 partitionCount * maxConnectionsPerPartion 이 됨.(3개 파티션이 있고 maxConnectionsPerPartion 이 5면 전체 DB Connection 은 15가 됨)
acquireIncrement: 파티션내 Connection 이 모두 소모되었을때 늘릴 Connection Count. 기본값은 10 이며 전체 Count가 아니라 파티션별 count임

WAS의 JNDI 로 사용

TOMCAT 설정

JNDI 로 사용시 WAS 구동시 BoneCP가 의존하는 library 를 찾기때문에 WAS의 lib 폴더에 의존성있는 library 를 넣어야 deploy 문제 없음

releaseHelperThreads 는 deprecated 이다.
IdleMaxAge 대신 idleMaxAgeInMinutes 를 써야 한다.
idleConnectionTestPeriod 대신 idleConnectionTestPeriodInMinutes 를 써야 한다.

https://github.com/wwadge/bonecp/blob/master/bonecp/src/main/resources/bonecp-default-config.xml

<Resource name="jdbc/spring-demo"  auth="Container"
   driverClass="com.mysql.jdbc.Driver"
   username="springdemo"
   password="demo1234"
   idleConnectionTestPeriodInMinutes="60"
   idleMaxAgeInMinutes="60"
   maxConnectionsPerPartition="30"
   minConnectionsPerPartition="5"
   partitionCount="3"
   acquireIncrement="5"   
   statementsCacheSize="100"
   factory="org.apache.naming.factory.BeanFactory"
   type="com.jolbox.bonecp.BoneCPDataSource"
   jdbcUrl="jdbc:mysql://localhost:3306/springdemo?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf8"
/>

tomcat의 경우 Context.xml 에 ResourceLink를 추가해 줘야 한다.

<Context>
   <ResourceLink name="jdbc/spring-demo" global="jdbc/spring-demo" type="javax.sql.DataSource"/>
</Context>
