Be careful of your attribute names as case matters. Attribute names =
class property names and class properties are usually referred to with a
lower case first letter as in initialLimit="5", not InitialLimit="5".

Hello!
I think that I have the same problem.
<Resource name="ehr" auth="Container" type="oracle.jdbc.pool.OracleDataSource"

What you are saying is that i can't use pooling on Tomcat/JNDI or only
in case of oracle.jdbc.pool.OracleDataSourceFactory?
Thanks a lot

Hello,
I am trying to set up 0racle connection pooling. Some of the
parameters are reflected normally, but some are specified via a property
lists. How do I set the property list properties using Tomcat/JNDI? I
can set up the basic DataSource, but I cannot set the maxLimit parameter
on the max number of connections because they are in the
setConnectionCacheProperties property map, not reflected.
The version of commons-dbcp that gets used with Tomcat knows how to
handle the property map, but unfortunately the simple factory Tomcat
uses to configure DBCP (which is part of DBCP) doesn't contain the feature.
On July 23rd the factory has been updated to include the property map
handling. The feature is waiting for a DBCP release (likely 1.3) since
then :(
We had a little trouble with updating our commons-pool dependency
recently, so I'm not sure how fast after a dbcp release tomcat will
actually adopt it.
If it's really important for you, you could build a dbcp snapshot, check
the commons pool version dependency and replace the components in Tomcat.

More specifically, here is my conf/Catalina/localhost/KMS.conf (My web
app is KMS).
# cat /opt/tomcat/conf/Catalina/localhost/KMS.xml
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/KMS" docBase="KMS" debug="5" reloadable="true"
crossContext="true">
<Resource name="jdbc/rkm" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
connectionCachingEnabled="true"
connectionCacheName="KmsConPool"
abandonedConnectionTimeout="200"
connectionWaitTimeout="200"
maxLimit="20"
url="jdbc:oracle:thin:@localhost:1521:rsakmpri"
user="local"
password="-THIS-SHOULD-BE-IGNORED-"
/> <!-- maxLimit ignored -->
</Context>
The problem is that parameters like connectionCachingEnabled are set
reflectively and work but some such as MaxLimit are set in property
lists.
Specifically doing this in ordinary, easy Java, from the Oracle manual:-
OracleDataSource ods = new OracleDataSource();
// set cache properties in map
java.util.Properties prop = new java.util.Properties();
prop.setProperty("MinLimit", "2");
prop.setProperty("MaxLimit", "10");
// set DataSource properties
String url = "jdbc:oracle:oci8:@";
ods.setURL(url);
ods.setConnectionCacheProperties (prop); //
<<<<<<<<<<<<<<<<<<<<<<<<<
ods.setUser("hr");
ods.setPassword("hr");
ods.setConnectionCachingEnabled(true);
ods.setConnectionCacheName("ImplicitCache01");
...
Connection conn = ods.getConnection(user, pass);
But of course this is "Enterprise" software, so it must be done in XML,
not Java. Any ideas as to how to do this most welcome.

PS. I have never seen any reference to the ability to put a file like
KMS.xml in the conf area. I certainly seems to work, and is very
necessary -- obviously one does not want site config in a war -- but
just not documented as far as I can tell.
