All Implemented Interfaces:

PASStartup

public class PASJdbcPoolStartup

extends java.lang.Object

implements PASStartup

A startup class for use with the Protomatter Application Server. It will create pools at startup based on configuration properties. This class looks for properties in the PAS properties file that look like this:

  ##
  ## Configuration properties for the pool.
  ##
  com.protomatter.jdbc.pool.POOLNAME=\
    pool.initialSize=pool-start-size,\
    pool.maxSize=pool-max-size,\
    pool.growBlock=grow-block-size,\
    pool.createWaitTime=wait-time,\
    jdbc.driver=driver-class-name,\
    jdbc.URL=connection-URL,\
    jdbc.validityCheckStatement=SQL-statement,\
    pool.refreshThreadCheckInterval=check-interval

  ##
  ## Connection properties for the pool.
  ##
  com.protomatter.jdbc.pool.POOLNAME.jdbcProperties=\
    key1=val1,\
    key2=val2
  

The properties in the first part of the example correspond to init parameters for the JdbcConnectionPool class. This class knows how to translate each option into the correct type (such as java.lang.Integer, etc) before initializing the pool. The properties defined in the second part of the example are passed in as the jdbc.properties init option.

A javax.sql.DataSource interface is also placed into JNDI for each pool at the "com.protomatter.jdbc.pool.PoolName" location.
