CWSOM0001I: ObjectManager using logFile {0} was cold started.
Explanation An empty logfile was given to the ObjectManager so it was cold started. Action None, unless you expected the ObjectManager to warm start. In which case, investigate why the log file was empty.
CWSOM0002I: ObjectManager using logFile {0} was warm started logFileType={1}.
Explanation A valid logfile was given to the ObjectManager which it was able to restart from. Action None, unless you expected the ObjectManager to cold start. In which case, investigate why the log file was not empty.
CWSOM0003I: ObjectManager using logFile {0} has shut down.
Explanation The ObjectManager was requested to shutdown. Action None, unless you did not expect the ObjectManager to shut down.
CWSOM0004I: ObjectManager using logFile {0} has shut down without performing a final checkpoint.
Explanation The ObjectManager was requested to shutdown without performing a final checkpoint, or shut down because of some previous error. Action None, unless you did not expect the ObjectManager to shut down without performing a final checkpoint. Examine diagnostic output to determine the cause of a unexpected shutdown.
CWSOM0005W: The ObjectManager found that the logFile was too full and will back out transaction {0}.
Explanation The ObjectManager was short of log file space after it had completed a checkpoint, it backed out the largest transaction in the log in order to release some space. Action You are trying to do too much transactional work for the size of log file we have configured. Consider whether your transactions are attempting to do too many updates, or whether you are trying to update too many large objects, or whether you are trying to run too many transactions at the same time, or whether your log file is too small and should be made larger.
CWSOM0100W: A transaction {0} was discovered during garbage collection and will be backed out.
Explanation The application lost its reference to a transaction and cannot complete the transaction. Thus, the ObjectManager will back out the transaction in order to free up its resources. Action Your application lost its reference to a transaction. If the application terminated abnormally there us nothing further to do. If however, the application lost its reference without terminating abnormally this could be considered to be a logic error in the application.
CWSOM0200W: The ObjectStore {0} with strategy STRATEGY_SAVE_ONLY_ON_SHUTDOWN could not safely be closed.
Explanation If there are active transactions at shutdown. ObjectStores with strategy STRATEGY_SAVE_ONLY_ON_SHUTDOWN cannot safely close as active transactions exist. Closing the ObjectStore might lead to it saving inconsistent data. The ObjectStore is left unchanged. Action Examine why active transactions exist. These active transactions might exist be because you are using an external transaction manager. If you cannot avoid having active transactions at shutdown then use an ObjectStore with a different storage strategy.
CWSOM0201W: The ObjectStore requested {0} bytes of storage when it currently has {1} bytes but received exception{2}.
