WLST modified db uname/pwd verification for JDBC resource-No Restart Server

Question

Hi,
I have created a WLST script for changing the db username and password for a particular jdbc resource.It is working fine.
But to verify whether the right username and password has been provided ,is there a way to test the db connection for the changed user name and password without restarting the server.
I also understand that there would be the cached connections of the previous user name and password for the jdbc resource.
Please let me know if I can do this using any API's in WLST or any other way.
Idea is to execute the change db user name and password and verification in one go.
Cheers,
Mohan

You could try something like
servers = domainRuntimeService.getServerRuntimes();
# this return an array, for example array(weblogic.management.runtime.ServerRuntimeMBean,[[MBeanServerInvocationHandler]com.bea:Name=AdminServer,Location=AdminServer,Type=ServerRuntime])
# we obtain the server to which the datasource is targetted
admin = servers[0];
jdbcruntime = admin.getJDBCServiceRuntime();
datasources = jdbcruntime.getJDBCDataSourceRuntimeMBeans();
# this returns an array of the active datasources on the server, for example array(weblogic.management.runtime.JDBCDataSourceRuntimeMBean,
# [[MBeanServerInvocationHandler]com.bea:ServerRuntime=AdminServer,Name=ExampleDataSource,Location=AdminServer,Type=JDBCDataSourceRuntime])
datasource = datasources[0];
# Reset the connection pool in the data source by shutting down and recreating all available database connections in the pool.
datasource.reset();
# Test the connection pool in the data source by reserving and releasing a connection from it.
test = datasource.testPool();
# Print out information about all the connections in the connection pool in the data source, if there are any.
datasource.dumpPool();
