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:

Process Status Description
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.
QUIESCING The process is starting to quiesce.
UNQUIESCING The process is moving from being quiesced to running.
QUIESCED The process is quiesced and will not service transactions.

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.
