Subject [jira] Closed: (OPENJPA-734) Commons DBCP parameters should be configurable.
Date Tue, 30 Sep 2008 22:25:44 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-734?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Dick closed OPENJPA-734.
--------------------------------

    Resolution: Fixed

Fixed in revision 700603. 

The change adds a dbcp.args property to pom.xml. The property is passed in to the surefire
test harness and used when to configure the connection pool.

The property may be set on the command line  or in a profile in .m2/settings.xml. 

Example command line usage : 
$ mvn test -Ddbcp.args=MaxActive =5,MaxIdle=2

Example settings.xml usage: 
<profile>
    <id>unreasonably-large-pool<id>
    <properties> 
         <dbcp.args>MaxActive=1000,MaxIdle=0,MaxWait=500</dbcp.args>
    </properties>
</profile> 

$ mvn test -Punreasonably-large-pool

More practical examples include increasing the MaxIdle to avoid the overhead of creating connections.


The default settings may be found in pom.xml (openjpa-persistence-jdbc) and are currently
MaxActive=100,MaxIdle=0,MaxWait=10000

> Per conversation on the users mailing list [1] it would be nice to make the connection
pool used for unit tests configurable. Some environments are not well suited to handle the
current list of defaults.
