Hi all, I am trying to use a connection pool in Tomcat to make JDBC connections to an Oracle Database. The pool works fine, because I can get a connection from it. The problem is that I want that Tomcat makes a set of connections at startup, and for that I used the initialSize parameter, but when I restart the tomcat any connection is established. I configured the connections to the database in the context.xml file, and his content is: <Context> <Resource name="jdbc/myoracle" auth="Container" type="javax.sql.DataSource" username="pret" password="pret" driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@10.197.92.48:1522:SIMEIDT" initialSize="2" maxActive="8"/> </context> The version of Tomcat is 6.0.10 I test the number of connections established with the following select: select machine, status from v$session; Can any body say me what is wrong. Is it necessary to configure another thing? Regards, Rui Torres
