Hi Gurus,

How can I release the JDBC connection that is hooked by ERXJDBCConnectionAnalyser class?

I've defined following properties:

er.extensions.ERXJDBCAdaptor.useConnectionBroker = true

dbMinConnectionsGLOBAL=1

dbMaxConnectionsGLOBAL=5

dbMaxCheckoutGLOBAL=600

dbDebugLevelGLOBAL=3

I've following code being called one of my direct actions for testing purpose:

public WOActionResults monitorAction() {

NSMutableDictionary<String, String> dictStatus = new NSMutableDictionary<String, String>();

for (EOModel m : EOModelGroup.defaultGroup().models()) {

ERXJDBCConnectionAnalyzer ca = new ERXJDBCConnectionAnalyzer(m);

try {

ca.testConnection();

dictStatus.put(m.name(), "OK");

} catch (Throwable t) {

dictStatus.put(m.name(), "Error: " + t.getMessage());

}

WOComponent page = pageWithName(Monitor.class.getName());

page.takeValueForKey(dictStatus, "dictStatus");

return page;

}

If I set the useConnectionBroker property to "false", it works okay. Otherwise I get following exception.

How can I enforce ERXJDBCConnectionAnalyser to release connection?

Thanks,

Farrukh
