CWSOM

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.
Action None, unless you did not expect the ObjectManager to shut down without performing a final checkpoint.
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 you 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 would not be able to complete it so 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 be closed as this might lead to their saving inconsistent data. The ObjectStore is left unchanged.
Action Examine why there are active transactions, this might 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}.
Explanation The file system could not allocate the required space. Attempts to allocate objects in the ObjectStore will fail.

CWSOM1009E: ObjectStore={0}(ObjectStore) generated sequenceNumber={1}(Long) which was already used by{2}(ManagedObject).
Explanation An internal error has occurred in the ObjectStore.
Action Report the problem to IBM service.

Explanation Only one token of each identity (objectStoreIdentifier and storedObjectIdentifier; store may exist, but the new Token and an existing one share the same identity.
Action The ObjectStore may be corrupt, contact IBM support.
CWSOM1011E: An invalid operation was attempted on Object={0} while it was in state={1}(int) {2}(String).

Explanation An attempt was made to unlock or replace a ManagedObject under a different transaction to the one that locked it. The attempt is rejected.
Action Examine the logic of the application using the ObjectManager Transaction.unlock(ManagedObject) interface to see why the two transactions are different.
CWSOM1017E: ObjectManagerState={0}(ObjectManagerState) caught exception={1}(Exception) trying to locate or create log file name={2}(String).
Explanation An exception was caught trying to open the named log file. The ObjectManager will not start.

Action See if another ObjectManager or another program is trying to use the same log file.
CWSOM1023E: Log file has no valid header.
Explanation The transaction log file contained data that the ObjectManager could not interpret.
Action Check that the log file is the correct one. If it is, contact IBM support.
CWSOM1024E: Attempt to set a transaction XID when it is already set existing XID={0}([]byte) rejectedXID={1}([]byte).
Explanation A transaction may only have one XID and it cannot be modified once set.
Action Examine the logic of the application and determine why it is trying to change the XID of a transaction that already has one.
CWSOM1025E: Attempt to set a transaction XID which is too long XID.length={0}(int).
Explanation An XID can have a maximum length of java.lang.Short.MAX_VALUE.

CWSOM1034E: An application attempted to start more that the defined maximum={0}(long) number of transactions.
Explanation The ObjectManager was asked to start more transactions than it has been configured for. The new transaction is not started.
Action Examine the logic of the application and discover why it tried to start too many transactions. Possibly it is starting them but not committing them or backing them out.
CWSOM1035E: The maximum number of active transactions was temporarily reduced current active transactions={0}(long) current capacity ={1}(long).
Explanation The ObjectManager was asked to start more transactions than it can support. Usually this has been reduced so that checkpoints can complete before the log file fills. The new transaction is not started.

CWSOM1039E: Duplicate key={0}(Object) conflicts with existing entry={1}(Map.Entry) locked by transaction={3}(InternalTransaction).
Explanation An attempt was made to add a unique key which already existed in the map and was not in a suitable state for replacement.

Action Make a request that is for more space than the currently used size.
CWSOM1041E: ObjectManager caught Exception={0}(java.nio.XXX Exception).
Explanation An nio Exception was caught by the ObjectManager, the IO operation could not be safely retried and was abandoned.
Action Investigate and fix the cause of the underlying Exception.
CWSOM1042E: ObjectStore={0}(ObjectStore) was asked to allocate space for ManagedObject={1}(ManagedObject) when it was full.
Explanation An ObjectStore was already full when a new allocate request was made. The allocation was not made.
Action Decide if you should make the ObjectStore larger or if you should remove some existing objects, or if you are trying to store more or larger objects than you had planned.
CWSOM1043E: ObjectManager was passed an invalid log file type={0}(int).
Explanation The ObjectManager constructor was passed a log file type that was not recognized as one of the LOG_FILE_TYPE_XXXX types. The ObjectManager is not instantiated.
Action Change the constructor invocation to use a recognized log file type.
CWSOM1044E: List={0}(List) was asked to create a sublist delimited by List.Entry={1}(List.Entry) which it did not contain.
Explanation A list was asked to create a sublist delimited by entries it did not contain. The sublist was not created.

Explanation An unrecognize signature was found in a ManagedObject, the deserialization was abandoned.
Action Contact IBM support.
CWSOM1046E: ObjectStore={0} was constructed using an invalid store strategy={1}(int).
Explanation ObjectStores can only be constructed with valid storage strategies.
Action Use a valid storage strategy to construct the ObjectStore.
CWSOM1047E: Attempt to construct an ObjectStore using, storeName={0}(String) and identifier {1} which has already been used by ObjectStore={2}
Explanation ObjectStore identifiers must be unique within an ObjectManager.
Action Add existing ObjectStores to the ObjectManagerbefore creating new ones, this allows the ObjectManager to avoid reusing the identifier.
CWSOM1048E: Object={0} discovered potentially corrupted data in Object={1}(Object).
Explanation For data protected by Guard bytes, a mismatch in the value of the Guard bytes has been found.
Action Contact IBM support.
