Resolving Storage Tier Issues

The storage tier is the architectural tier where data is stored and managed through objects called atoms. Storage Managers are part of the storage tier in NuoDB’s architecture.

SQL and storage tier issues generally revolve around Transaction Engines (TEs) and/or SMs that fail to run or fail to remain running. By default, when these processes start the agent.log file will contain information regarding the state of the processes. The issues described in the following topics illustrate common messages that might be found in the agent.log file regarding these events. See also: Using Log Files.
