Hi,
I have a controller with two backends one enabled and one disabled.
After sometimes, I want to enable the second backend.
So I use the JMX method enableBackendFromCheckpoint.
During the recovery process every access to the two
Backends are suspended so if a write request occurred during the
recovery process it will be delayed.
The code of the method AbstractScheduler.addSuspendedRequest is
synchronized (suspendedRequests)
{
suspendedRequests.add(obj);
}
synchronized (totalOrderQueue)
{
totalOrderQueue.notifyAll();
}
But if the VirtualDatabase is not a DistributedVirtualDatabase,
the field totalOrderQueue queue is null and a NPE is thrown.
Is it a bug or I cannot do this?
Xavier.
