Dear Monet Team,
I've been using the JDBC driver and have recently noticed that under load, calls to DriverManager.getConnection() will sometimes appear to hang.
I was able to resolve this problem by serializing access to getConnection() using a synchronized block. I haven't had a chance to dig through the JDBC driver code to see what would account for this, but I figured I'd make you aware just in case someone else runs into this.
If would be useful to know what the threads are hanging on when you feel they are stuck. I suspect that the server doesn't like you bombarding it in parallel. The code you reference is all pretty object oriented, and not using any shared resources. -- Fabian Groffen fabian@monetdb.org column-store pioneer http://www.monetdb.org/Home _______________________________________________ users-list mailing list users-list@monetdb.org http://mail.monetdb.org/mailman/listinfo/users-list
