tomcat - MaxActive database connection parameter doesn't work -


i have problem datasource configuration.

i have tomcat 7 java 7 , quartz web application. application has datasource configured: 

<resource     auth="container"    driverclassname="com.mysql.jdbc.driver"    factory="org.apache.tomcat.dbcp.dbcp.basicdatasourcefactory"    logabandoned="true"    maxactive="3"    maxidle="1"    maxwait="10000"    name="jdbc/name"    password="xxxxxx"    removeabandoned="true"    removeabandonedtimeout="120"    type="javax.sql.datasource"    url="jdbc:mysql://xxxxxx:3306/xxxxx?autoreconnect=true&zerodatetimebehavior=converttonull&rewritebatchedstatements=true"    username="usr"    validationquery="select 1" />

with maxactive = 3 expected see no more 3 connection opened. instead of this, see new connection opened every time quartz job starts, untill 8 connection (don't know if default limit).

so seems parameter not considered, other yes, because connection database correct username, password etc... ok.

can me please?

thanks

i reply myself

it problem of factory org.apache.tomcat.dbcp.dbcp.basicdatasourcefactory

using org.apache.tomcat.dbcp.dbcp2.basicdatasourcefactory (replacing originial tomcat 7 jar) works

don't know why, works. org.apache.tomcat.dbcp.dbcp.basicdatasourcefactory if initialsize set 8, 1 instantiated. replacinig org.apache.tomcat.dbcp.dbcp2.basicdatasourcefactory, 8 instantiated
