Emmanuel Cecchet commented on SEQUOIA-1050:
-------------------------------------------
public void setShutdownCheckpoint()
{
RecoveryLog recoveryLog = requestManager.getRecoveryLog();
if (recoveryLog != null)
try
{
recoveryLog
.storeCheckpoint("shutdown" + controller.getControllerName());
}
catch (SQLException e)
{
logger.warn("Error while setting shutdown checkpoint", e);
}
}
Should be fixed with:
public void setShutdownCheckpoint()
{
RecoveryLog recoveryLog = requestManager.getRecoveryLog();
if (recoveryLog != null)
try
{
recoveryLog
.storeCheckpoint(buildCheckpointName("shutdown"));
}
catch (SQLException e)
{
logger.warn("Error while setting shutdown checkpoint", e);
}
}
> Duplicate shutdown checkpoint names with non-distributed virtual databases
> --------------------------------------------------------------------------

> Key: SEQUOIA-1050
> URL: https://forge.continuent.org/jira/browse/SEQUOIA-1050
> Project: Sequoia
> Type: Bug
> Components: Recovery Log, Core
> Environment: Any non-distributed virtual database with recovery log
> Reporter: Emmanuel Cecchet
> Assignee: Emmanuel Cecchet
> Priority: Critical
>
>
> The code in VirtualDatabase.setShutdownCheckpoint does not generate unique
> checkpoint names. Shutting down the controller for the second time on the
> same controller will generate a duplicate entry exception in the recovery log.
> The method should use buildCheckpointName("shutdown") instead like in the
> DistributedVirtualDatabase implementation.
