About Dominant Database Status
NuoDB determines a dominant database status, which is the most common status among the database's processes. Each database process (transaction engine, storage manager) has its own status, which can be any one of the following:
|ACTIVE||The process is starting. This is a transitional state that you will rarely see.|
|RUNNING||The process is doing useful work or available for doing useful work.|
|SYNCING||The storage manager is synchronizing its state with an up-to-date storage manager. Transaction engines are never in this state.|
The process is doing a soft shutdown. Before shutting down, transaction engines either wait for client connections to close or sever connections if they do not close within a certain amount of time. Storage managers flush the journal and archive to disk and then shut down.
