Subject: [grouper-users] vtldapPooling options seem to be ignored.

 

After having trouble with pooled connections. I tried to adjust the parameters by using the options provided by https://code.google.com/p/vt-middleware/wiki/vtldapPooling. I'm pretty sure that at least the sources.xml referencing the ldap.properties file is ignoring those parameters.

I've tried setting edu.vt.middleware.ldap.pool.minPoolSize to "5" but I still only get three connections on startup. I've adjusted the edu.vt.middleware.ldap.pool.pruneTimerPeriod and edu.vt.middleware.ldap.pool.expirationTime but I never see the disconnect. at the theoretical maximum of two minutes. experationTime to 90 seconds and pruneTimerPeriod to 30.

We have a load balancer sitting between us and the multiple LDAP server backend, however if a connection is open and idle, the LB will drop the connection silently after about three minutes. However the vtldapPool defaults keep the connections open for a lot longer than the LB allows.
