Hi ,
I am trying to register a com.ibm.db2.jcc.DB2ConnectionPoolDataSource
datasource in tomcat 5.5.4.
I am not getting any exception's while doing a context lookup and gives me
the datasource.
However the paramaeter's that are set with that Resource are always null.

I didn't work on DB2 before, but i have configured Oracle and MySql
database in the same way.
First, you have to get the ideal connector for DB2, jar file, and
place it inside CATALINA_HOME/lib, or JAVA_HOME/lib/ext.
Second, Define your resource name, you already did.

Basically 32bit better for small volume servers that can live with a 2GB

Fundemental problem is that a process can only use 2GB no matter how

Strictly speaking, they still do, but global suspends occur much, much
