OFBiz trunk + Apache DBCP2 + MySQL connectivity issues
Hello Everyone,
I've been observing frequent errors such as
"org.ofbiz.entity.GenericDataSourceException: Unable to esablish a
connection with the database. (Unable to acquire a new connection from the
pool)". While OFBiz restart helps for sometime, but we would like to avoid
frequent restarts.
I'm wondering if someone else has faced same issues or would like to share
their thoughts. Could it be that upgrade to DBCP2 has introduced new bugs?
I'm using OFBiz trunk (revision 1704086) + MySQL v5.6 + MySQL JDBC driver
v5.1.38 + JDK 7. This version uses Apache DBCP2.
entityengine.xml configuration -
- pool-minsize = "2"
- pool-maxsize = "250"
- time-between-eviction-runs-millis="600000" [used to give same errors with
-1]
Below is the stacktrace of associated with one of these errors -
org.ofbiz.entity.GenericDataSourceException: Unable to esablish a
connection with the database. (Unable to acquire a new connection from the
pool). Rolling back transaction.
org.ofbiz.entity.GenericDataSourceException: Unable to esablish a
connection with the database. (Unable to acquire a new connection from the
pool)

Re: OFBiz trunk + Apache DBCP2 + MySQL connectivity issues
Posted by Jacques Le Roux <ja...@les7arts.com>.
Before doing so we could check if there are any changes in PoolableManagedConnectionFactory else it's unlikely that the issue Scott fixed is fixed in
2.1.1 (we use 2.1)
We could also work with commons to see if Scott's fix can/should be incorporated... (beware working with the commons team can be rough)

Maybe upgrading the jar to commons-dbcp2-2.1.1.jar will address the issue.

Re: OFBiz trunk + Apache DBCP2 + MySQL connectivity issues
Posted by Scott Gray <sc...@hotwaxsystems.com>.
I'm pretty sure it's a bug in DBCP2 but the issue was complicated and I
didn't have time to do any more than fix it at the time. Maybe it doesn't
affect all dbs though because I'm surprised no one else has raised the
issue. I can't say what affect it might have on other database servers.

Re: OFBiz trunk + Apache DBCP2 + MySQL connectivity issues
Posted by Scott Gray <sc...@hotwaxsystems.com>.
Actually yes, I have encountered this. I fixed it with the following
class, which you would then use in the DBCPConnectionFactory class in place
of the PoolableManagedConnectionFactory.
/**
* An extension to the DBCP2 PoolableManagedConnectionFactory that ensures
that
* PoolableConnections are always set to setCacheState(false). This is
needed
* because otherwise PoolableConnections will cache the autoCommit setting
of the
* underlying connection even though the flag on the underlying connection
is often set
* directly (specifically by LocalXAConnectionFactory.LocalXAResource, see
start()
* and commit()).
*/
public class DBCPPoolableManagedConnectionFactory extends
PoolableManagedConnectionFactory {
@Override
public synchronized PooledObject<PoolableConnection> makeObject() throws
Exception {
PooledObject<PoolableConnection> pooledObject = super.makeObject();
pooledObject.getObject().setCacheState(false);
return pooledObject;
}
public DBCPPoolableManagedConnectionFactory(XAConnectionFactory
connFactory, ObjectName dataSourceJmxName) {
super(connFactory, dataSourceJmxName);
}
}
