[Sequoiadb-discuss] Driver problem

[BESSON-DEBLON, Pierre \(S. H. TECH\) <PIE...@ai...>]

Sorry for previous mail ....

Hi,


We have a problem with our sequoia : we have 2 controllers, the JDBC URL looks like that jdbc jdbc:sequoia://cont1,cont2/db.
If we have cont1 down and cont2 with a deactivated backend, the requests fail even when cont2 backend is reactivated.

Digging in the source code, the following code seems suspicious :
ControllerPingSender.run() :
        ....
        for (Iterator it = controllers.getControllerIterator(); it.hasNext();)
        {
          ControllerInfo ctrl = (ControllerInfo) it.next();
          sendPingTo(ctrl);
        }

When the first controller is unreachable, the sendPing will throw an exception and the sendPing will not be sent to others.

What will be the consequences ? Could it explain our problem ?
